Fix cross-compiling of ioctlsort

2015-02-27T04:43:06+00:00

Use the AX_PROG_CC_FOR_BUILD helper to set up build settings when cross
compiling.  This way ioctlsort uses the build tools all the time.

* configure.ac: Call AX_PROG_CC_FOR_BUILD.
* Makefile.am (ioctlsort_CC): Set to CC_FOR_BUILD.
(ioctlsort_CPPFLAGS): Change CPPFLAGS to CPPFLAGS_FOR_BUILD.
(ioctlsort_CFLAGS): Change CFLAGS to CFLAGS_FOR_BUILD.
(ioctlsort_LDFLAGS): Change LDFLAGS to LDFLAGS_FOR_BUILD.
(ioctlsort_LD): Delete.
(ioctlsort%): Change to ioctlsort%$(BUILD_EXEEXT).  Use ioctlsort_CFLAGS.
* m4/ax_prog_cc_for_build.m4: Import from the autoconf-archive package.

Update warnings.m4

2015-01-21T21:06:10+00:00

* m4/warnings.m4: Update from gnulib.

configure.ac: remove unused AC_INCLUDEDIR

2015-01-21T16:43:18+00:00

* configure.ac (AC_INCLUDEDIR): Remove.
* m4/includedir.m4: Remove.

Use AC_CHECK_TYPES to check for struct statfs64

2015-01-08T04:12:29+00:00

* m4/statfs.m4: Remove.
* configure.ac (AC_STATFS64): Remove.
(AC_CHECK_TYPES): Add struct statfs64.
* statfs.c: Replace HAVE_STATFS64 with HAVE_STRUCT_STATFS64.

Use AC_CHECK_TYPES to check for struct stat64

2015-01-08T04:06:06+00:00

* m4/stat.m4: Remove.
* configure.ac (AC_STAT64): Remove.
(AC_CHECK_TYPES): Add struct stat64.
* file.c: Replace HAVE_STAT64 with HAVE_STRUCT_STAT64.

Remove unused AC_OFF_T_IS_LONG_LONG configure check

2013-11-12T15:43:06+00:00

* configure.ac: Remove AC_OFF_T_IS_LONG_LONG.
* m4/long_long.m4: Likewise.

Implement prlimit64 decoding, rewrite [gs]etrlimit decoding

2012-03-16T19:05:21+00:00

* configure.ac: Remove AC_RLIM_T_IS_LONG_LONG call.
Define SIZEOF_RLIM_T.
* m4/long_long.m4 (AC_RLIM_T_IS_LONG_LONG): Remove.
* linux/dummy.h (sys_prlimit64): Remove.
* linux/syscall.h (sys_prlimit64): New prototype.
* resource.c (resources): Reindent, add RLIMIT_RTTIME.
(sprintrlim, print_rlimit32, sys_getrlimit, sys_setrlimit): Remove.
[HAVE_LONG_LONG_RLIM_T]: Remove dead code.
[_LFS64_LARGEFILE || HAVE_LONG_LONG_RLIM_T]: Likewise.
(sprint_rlim64, print_rlimit64, decode_rlimit64, sprint_rlim32,
print_rlimit32, decode_rlimit, sys_getrlimit, sys_setrlimit,
sys_prlimit64): New functions.

Remove parts of automake machinery which are not needed on Linux

2012-02-25T14:34:10+00:00

This change is a verbatim part of Dmitry's changes to remove support
for non-Linux architectures.

* Makefile.am: Don't install PORTING file. Install README-linux-ptrace file.
Set OS variable to linux unconditionally.
* configure.ac: Remove code to set opsys variable, and its usage.
Remove checks for headers which are never present on Linux.
* m4/stat.m4: Remove 'ifdef LINUX' check.
* m4/statfs.m4: Likewise.

Manual removal of non-Linux source, documentation, etc.

2012-02-25T01:30:32+00:00

Remove non-Linux source directories: freebsd/, svr4/, sunos4/, svr4/.
Remove README-freebsd, README-sunos4, README-svr4, m4/procfs.m4.

linux/sparc/{errnoent1,ioctlent1,signalent1}.h used to point to svr4/ files -
replace their contents with copies of used (and now deleted) files.
Make linux/sparc64/{errnoent1,ioctlent1,signalent1}.h include these files
instead of svr4/* ones.

Makefile.am: remove references to deleted files.
configure.ac: Remove a few tests which make no sense on Linux.
Man page: remove non-Linux quirks information.

Fix off_t/rlim_t size checks when cross-compiling

2010-09-15T15:36:00+00:00

The current off_t/rlim_t size checks (wrt size of long long) use AC_RUN
which obviously doesn't work when cross-compiling.  While we don't hit
any configure errors, the fall back code is pretty dumb (which is to say
there isn't any).  Considering the code in question though, we can use
some fun compiler tricks with sizeof and array lengths to turn it into
a pure build test and avoid the RUN issue completely.

* m4/long_long.m4 (AC_OFF_T_IS_LONG_LONG, AC_RLIM_T_IS_LONG_LONG):
Convert from AC_RUN_IFELSE to AC_COMPILE_IFELSE.
