From 06f2392bb648d84f231e4f19be79336870d26ed3 Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Sun, 12 Jun 2022 07:24:22 -0700 Subject: Modernize to current gettext, gnulib MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * .gitignore, po/.gitignore: Revamp to match current source. * README: Fix typo in file name. * am/rmt.m4 (PU_RMT): Modernize to use AC_PREPROC_IFELSE instead of AC_TRY_CPP. * am/rmt.m4 (PU_RMT): * configure.ac: Modernize to use AS_HELP_STRING instead of AC_HELP_STRING. * am/system.m4 (PU_SYSTEM): * configure.ac: Remove obsolescent AC_HEADER_STDC. Use AC_CHECK_MEMBERS([struct stat.st_blksize]) instead of AC_STRUCT_ST_BLKSIZE. * am/system.m4 (PU_SYSTEM): Use AC_CHECK_HEADERS_ONCE([sys/time.h]) instead of obsolescent AC_HEADER_TIME. * bootstrap: Sync from Gnulib. * build-aux/bootstrap: Remove. * bootstrap.conf: Simplify. Don’t make m4, $source_base. (bootstrap_post_import_hook): New function, replacing a direct write. * configure.ac: Remove calls to no-longer-needed macros AC_ISC_POSIX, AM_STDBOOL_H, AC_HEADER_STDC, AC_TYPE_SIGNAL. Modernize to use AC_COMPILE_ELSE instead of AC_TRY_COMPILE. Remove MU_DEBUG_MODE, paxutils_GNULIB (not sure what those were from). Fix quoting in warning Remove Iconv code, as the iconv module should do this now. Update Gettext version from 0.12.1 (2003) to 0.21 (2020). Use AC_CONFIG_FILES. All uses of corresponding C macros changed. * gnulib.modules, paxlib.modules: Switch from gettext to gettext-h. * paxlib.modules: Add iconv. --- .gitignore | 32 +- README | 11 +- am/rmt.m4 | 20 +- am/system.m4 | 11 +- bootstrap | 1185 +++++++++++++++++++++++++++++++++++---------------- bootstrap.conf | 14 +- build-aux/bootstrap | 270 ------------ configure.ac | 51 +-- gnulib.modules | 4 +- lib/rtapelib.c | 11 +- lib/system.h | 7 +- paxlib.modules | 5 +- paxlib/rtape.c | 11 +- po/.gitignore | 29 +- 14 files changed, 912 insertions(+), 749 deletions(-) delete mode 100755 build-aux/bootstrap diff --git a/.gitignore b/.gitignore index a353d05..85e10df 100644 --- a/.gitignore +++ b/.gitignore @@ -3,23 +3,25 @@ *.lo *.o *~ -.bootstrap .deps .emacs* -.libs -ABOUT-NLS +/.bootstrap +/ABOUT-NLS +/INSTALL +/[0-9]* +/aclocal.m4 +/am/.gitignore +/autom4te.cache/ +/build-aux +/config.h +/config.h.in +/config.log +/config.status +/configure +/gnu/ +/gnulib/ +/m4/ +/stamp-h1 ChangeLog -INSTALL Makefile Makefile.in -aclocal.m4 -autom4te.cache -build-aux -config.h -config.h.in -config.log -config.status -configure -gnu -m4 -stamp-h1 diff --git a/README b/README index bb710c2..92a1849 100644 --- a/README +++ b/README @@ -10,7 +10,7 @@ GNU paxutils aims to provide: 3. pax implementation, conforming to POSIX standard.
