Cross-configuring Lsof Introduction ============ Lsof cross-configuration is useful when the target dialect or target dialect version for which lsof is to be configured and built differs from the one on which the Configure operation is done. Marty Leisner <leisner@sdsp.mc.xerox.com> suggested the method described here for lsof cross-configuration, and he supplied modifications to the Configure script for cross-configuring Linux lsof. Marty says: "I used this to successfully compile (lsof) on the same machine for (Linux) 2.0.30 and 2.1.42. (I normally don't bring up a 2.1.42 machine all the time). Also it (the 2.0.30 system) doesn't have much storage and compiles on it are slow. Set LSOF_VERS if it's not the (version of the) current system. (Actually, you should get the version out of include/linux/version.h.) Define LINUX_KERNEL to (the path) where the kernel sources are (located). (No longer necessary as of lsof revision 4.53.) This should work on most systems; they put a kernel in /usr/src/linux, which is the default. Now I can just do: LINUX_KERNEL=/some/other/kernel LSOF_VERS=2142 ./Configure linux Comments? Its very convenient when running multiple kernels. (It would be (have been) very handy when the structures changed between 2.0.2* and 2.0.30 , or whatever.) I run multiple OSes at a time (not to mention multiple architectures. It's very pleasant to cross-build either operating systems or versions." So, the situation is that you have lsof sources on a UNIX dialect version, and you want to configure them to build lsof for some other version of the same dialect, or perhaps for some other UNIX dialect altogether. The Cross-Configure Method ========================== The lsof cross-configure method uses environment variables to tell the lsof Configure script about the target dialect. The environment variables may specify alternate locations for Configure to examine when it determines characteristics of the target, or they may specify the values Configure would discover when it examined the target's characteristics. Consult each environment variable description for the UNIX dialect in which you're interested to see how it affects the operation of the Configure script. The number and values of the variables differ by dialect. Each variable begins with an upper case version of the dialect's Configure abbreviation -- e.g., AIX for aix or aixgcc, LINUX for linux, UW for uw (UnixWare), etc. Of course, the UNIX dialect's version is probably different from that of the system on which you're doing the cross-configuration, so you will need to specify the new version, too. For example, to configure for FreeBSD 3.0 on a 2.1.7 system, where the standard 3.0 header files are in /3.0/usr/include and the 3.0 system sources are in /3.0/sys, do this: LSOF_VERS=300 LSOF_INCLUDE=/3.0/usr/include \ FREEBSD_SYS=/3.0/sys Configure -n freebsd General Environment Variables ============================= There are some environment variables whose names don't begin with an upper case rendering of a dialect abbreviation. Generally they apply to all dialects. AFS_VICE is for AFS configuration. It need be set only if lsof supports AFS on your dialect and you want to specify an alternate path to the VICE files. default: /usr/vice LSOF_AR is the path to and arguments for the library archive application that is used to build the lsof library, liblsof.a. When this value is placed in the library Makefile as the contents of the AR make string, it is followed by the path to the library and the relative paths of the library module default: ar cr LSOF_ARCH is the architecture type string for the system. Usually this is the output of `uname -m`. Consult the Configure script for details. The LSOF_ARCH value may have to be quoted if it contains spaces. default: auto-detection (e.g., from `uname -m`) LSOF_BLDCMT may be used to introduce a builder's comment into lsof's -v output. It defaults to the null string, causing no builder's comment to appear in -v output. default: none LSOF_CC is the path to the C compiler. You may need to specify it if your C compiler is in a non-standard place, not found by your path. If you specify a compiler different from the expected default, you may have to change the compile time flags by specifying new CFGF, CFGL, and DEBUG strings on the make command line. default: normally cc, but some dialects have other defaults and some have auto-detection. Check the dialect stanza in the lsof Configure script to see how LSOF_CC is set by default. LSOF_CCV is the C compiler version. You should specify it if you have specified a compiler path in LSOF_CC. default: the lsof Configure script knows how to find the version number of gcc and some other dialect-specific compilers. Check the dialect stanza in the lsof Configure script to see how lsof_CCV is set by default. LSOF_CFGF may be used to specify additional configuration values that will appear in the CFGF string of the Makefile. LSOF_CFGL may be used to specify additional library specifications that will appear in the CFGL string of the Makefile. LSOF_HOST may be used to specify a value in lsof's -v output other than the name of the host where lsof was built. A value of "none" inhibits host name display in -v output. default: the dialect's host name application -- e.g., hostname or uname -n LSOF_INCLUDE is the path to the standard header files. You may need to specify it if you want Configure to test header files in a tree different from /usr/include, and you want to compile lsof from the header files in that different tree. LSOF_LOGNAME may be used to specify a value in lsof's -v output other than the one in the LOGNAME environment variable for the login name of the person who built lsof. A value of "none" inhibits login name display in -v output. default: the LOGNAME environment variable LSOF_MAKE is the path to the make command. deafult: the output of `which make`, if it is not NULL; otherwise the string "make". LSOF_MKC may be used to specify an alternate method of connecting dialect sources to the top-level lsof directory. See 00PORTING for more information. default: ln -s LSOF_RANLIB may be used to specify an alternate command for the randomizing of the lsof library. default: ranlib for most dialects none for: IBM AIX; HP-UX; SCO OpenServer; Solaris and SCO|Caldera UnixWare LSOF_SYSINFO may be used to specify a value in lsof's -v output other than the standard system identification -- e.g., output from uname. A value of "none" inhibits system information display in -v output. default: the dialect's standard system identification application output -- e.g., uname, sysinfo LSOF_USER may be used to specify a value in lsof's -v output other than the one in the USER environment variable for the login name of the person who built lsof. A value of "none" inhibits login name display in -v output. default: the USER environment variable LSOF_VERS is the target dialect version number. It must be stated in the dialect's form -- e.g., FreeBSD 2.0.5 is given as 205, Solaris 7 as 70000, etc. The table, "Abbreviations, Variable Prefixes, and Version Numbers," in this file gives the form for LSOF_VERS for each dialect lsof supports. default: auto-detection (e.g., from `uname -r`) LSOF_VSTR is the version string from which LSOF_VERS is derived. Usually this is the output of `uname -r` or `uname -v`. Consult the Configure script for details. The LSOF_VSTR value may have to be quoted if it contains spaces. default: auto-detection (e.g., output from `hostname`, `uname -r`, or `uname -v) Make Strings ============ The CFGF, CFGL, and DEBUG strings can be specified on the make command line to change default values placed in the top-level and library Makefiles by Configure. For example, Configure usually defines the compiler optimization level to be -O, but you can change that with "DEBUG=-g" on the make command -- e.g., $ make DEBUG=-g lsof Similarly, the CFGF string contains miscellaneous compile-time options, and CFGL contains loader options. Consult the Makefiles generated by Configure for the values it defines by default for CFGF and CFGL. As an example, Configure might define CFGL to be "-L./lib -llsof -w" for NextStep 3.1; to remove "-w", use this make invocation: $ make CFGL="-L./lib -llsof" Abbreviations, Variable Prefixes, and Version Numbers ===================================================== The following table describes the relationship between Configure abbreviations, environment variable prefixes, and lsof UNIX dialect version numbers. The lsof UNIX dialect version number must be declared exactly in the listed form when supplied via the LSOF_VERS environment variable.

Dialect-Specific Environment Variables ====================================== Here are the dialect-specific environment variables, listed alphabetically. The first part of any environment variable will be the dialect abbreviation, as specified to Configure, converted to upper case characters. See the `Configure -help` output for a listing of the abbreviations. AIX_ARCH specifies the AIX architecture when the AIX version is 5.0 or higher. A value of "" signifies POWER; "ia64", 64 bit x86 (Itanium). default: none (tested via `uname -a`) AIX_HAS_AFS specifies the state of AIX ADS support when the AIX version is 4.3.3 or lower. (Lsof doesn't support AFS above AIX 4.3.3.) A value of "" allows the Configure script to determine the AFS support state; "no", disables AFS support; and "yes", forces the enabling of AFS support. default: none (tested via presence of AFS files and the lsof AFSConfig shell script) AIX_KERNBITS specifies the kernel bit size, 32 or 64, of the Power architecture AIX 5.x kernel for which lsof was built. default: determined by the Configure script with a test program that uses <sys/systemcfg.h> macros. AIX_USHACK If this environment variable has a value of "Y" or "y", and if the aixgcc Configure abbreviation is selected, the AIX 4.1 and greater gcc user structure hack is activated; any other non-NULL value, it's not set; a NULL value, it's tested by compilation. default: none (tested by compilation) DARWIN_XNUDIR If this environment variable has a value, the value is used as the path to the Darwin XNU kernel source code. default: none (entry requested) DARWIN_XNU_HEADERS If this environment variable has a value, the value is used as the path to the Darwin XNU kernel header files. This path would match the DSTROOT environment variable used when a "make installhdrs" was executed from the Darwin XNU kernel source directory. default: none DU_ADVFSV specifies the DEC OSF/1, Digital UNIX, or Tru64 UNIX ADVFS file system version -- e.g., 200 for 2.0, 400 for 4.0, etc. default: determined via /usr/sbin/setld DU_CDIR specifies the name of the DEC OSF/1, Digital UNIX, or Tru64 UNIX system configuration directory. default: first host name component, converted to upper case DU_SHLIB specifies the DEC OSF/1, Digital UNIX, or Tru64 UNIX shared library directory path. default: /usr/shlib DU_SYSDIR DEC OSF/1, Digital UNIX, or Tru64 UNIX system directory path. 2.x and 3.x default: /sys 4.x default: /usr/sys FREEBSD_KERNEL specifies the path to the FreeBSD kernel for FreeBSD version less than 2.0. default: /386bsd FREEBSD_SYS specifies the path to the FreeBSD system source directory. default: /sys HPUX_BASE specifies the HP-UX lsof source code base, kmem or pstat, to be used. default: determined by testing for the /usr/include/sys/pstat subdirectory HPUX_BOOTFILE specifies the file in which lsof's Configure script can find kernel information. This specification may be useful for defining the path to a copy of /stand/vmunix that has been processed by pxdb or q4pxdb. default: /stand/vmunix HPUX_CCDIR1 specifies the first directory where Configure might find an HP-UX C compiler. This is ignored when LSOF_CC has been specified. default: /bin HPUX_CCDIR2 specifies the second directory where Configure might find an HP-UX C compiler.

Default: assumed to be "Y" if <selinux/selinux.h> exists LINUX_INCL specifies the path to the header file tree: default: /usr/include LINUX_LSEEK If this environment variable has a value of "Y" or "y", Configure uses Makefile.lseek in place of Makefile in order to enable use of the private lseek() function for 2.1.x kernels; any other non-NULL value, Makefile.lseek will isn't used; a NULL value, the alternate lseek() need is determined by compilation. default: determined by test program LINUX_VERSION_CODE specifies the value of the LINUX_VERSION_CODE in the same decimal form as found in the LINUX_VERSION_CODE #define of /usr/include/linux/version.h: default: the value of LINUX_VERSION_CODE in /usr/include/linux/version.h NETBSD_SYS specifies the path to the NetBSD system source directory. default: /usr/include NETBSD_UVM If this environment variable has a value of "Y" or "y", the NetBSD system uses the UVM virtual memory system; any other non-NULL value, it does not; a NULL value, it will be determined by the contents of /etc/mk.conf. default: tested by grep'ping /etc/mk.conf OPENBSD_SYS specifies the path to the OpenBSD system source directory. default: /sys OPENBSD_UVM If this environment variable has a value of "Y" or "y", the OpenBSD system uses the UVM virtual memory system; any other non-NULL value, it does not; a NULL value, it will be determined by examining /bsd. default: tested by grep'ping `nm /bsd` output OSR_CFGF The value of this environment variable is made the initial value for the compiler flags the lsof Configure script constructs for the Makefile CFGF macro. default: "" OSR_CFGL The value of this environment variable is made the initial value for the loader flags the lsof Configure script constructs for the Makefile CFGL macro. default: "" OSR_STATLSTAT If this environment variable has a value of "Y" or "y", HAS_STATLSTAT is defined in the Makefile's CFGL string; any other non-NULL value, it's not defined; a NULL value, it is determined with nm and grep. default: determined with nm and grep SOLARIS_23P101318 If this environment variable has a non-NULL value, the value is interpreted as the patch level of the Solaris 2.3 P101318 patch. default: pkginfo tested with grep SOLARIS_24P101945 If this environment variable has a non-NULL value, the value is interpreted as the patch level of the Solaris 2.4 P101945 patch. default: pkginfo tested with grep SOLARIS_24P102303 If this environment variable has a non-NULL value, the value is interpreted as the patch level of the Solaris 2.4 P102303 patch. default: pkginfo tested with grep SOLARIS_26PR_GWINDOWS If this environment variable has a value of "Y" or "y", the HASPR_GWINDOWS definition is set in the Solaris 2.6 and 7 Makefile's CFG string; any other non-NULL value, it's not set; a NULL value, it's tested by compilation. default: tested by compilation SOLARIS_26PR_LDT If this environment variable has a value of "Y" or "y", the HASPR_LDT definition is set in the Solaris 2.6 Makefile's CFGL string; any other non-NULL value, it's not set; a NULL value, it's tested by compilation. default: tested by compilation SOLARIS_CCDIR specifies the path to the Sun C compiler -- i.e., when `Configure solariscc` is used. This is ignored when LSOF_CC has been specified. default: /opt/SUNWspro/bin SOLARIS_INSTR specifies the Sun C compiler target instruction set when building lsof for a 64 bit kernel -- i.e., when the Configure abbreviation is "solariscc".

If SOLARIS_VXFSINCL is not set, the default is used. default: VxFS < 4.0: /opt/VRTSvxfs/include VxFS 4.0 and above: /opt/VRTSfssdk/<version>/include SOLARIS_VXFSLIB This environment variable defines the path to the VxFS 3.4 or greater utility libraries, libvxfsutil.a (32 bit) and libvxfsutil64.a (64 bit). If SOLARIS_VXFSLIB is not set, the default is used. Note: end SOLARIS_VXFSLIB at the "/lib" component; do NOT put "/sparcv9" at its end. The lsof Configure script will add "/sparcv9" if it is required; hence, if Configure finds that "/sparcv9" is needed, your SOLARIS_VXFSLIB directory tree must have a sparcv9 subdirectory. default: `dirname $SOLARIS_VXFSINCL`/lib SUN_AFSAPATHDEF specifies the path to the AFS library modload file for either Solaris or SunOS. default: /usr/vice/etc/modload/libafs Verified with ls.
