autoconf: Use autoconf to write installation directories to config.mak.autogen This is beginning of patch series introducing installation configuration using autoconf (and no other autotools) to git. The idea is to generate config.mak.autogen using ./configure (generated from configure.ac by running autoconf) from config.mak.in, so one can use autoconf as an _alternative_ to ordinary Makefile, and creating one's own config.mak. Local settings in config.mak override generated settings in config.mak.autogen This patch includes minimal configure.ac and config.mak.in, so one can set installation directories using autoconf generated ./configure script e.g. ./configure --prefix=/usr Signed-off-by: Jakub Narebski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <junkio@cox.net>

CC = @CC@
Fix compilation with Sun CC - Add the CFLAGS variable to config.mak.in to override the Makefile's default, which is gcc-specific and won't work with Sun CC. - Prefer "cc" over "gcc", because Pasky's Git.pm will not compile with gcc on Solaris at all. On Linux and the free BSDs "cc" is linked to "gcc" anyway. - Set correct flag to generate position-independent code. - Add "-xO3" (= use default optimization level) to CFLAGS.

config.mak.in: Pass on LDFLAGS from configure The configure script allows you to specify flags to pass to the linker step in the LDFLAGS environment variable but this was being ignored in the Makefile.

configure: auto detect dynamic library path switches Most systems (e.g. Linux gcc) use "-Wl,-rpath," to pass to the linker the runtime dynamic library paths. Some other systems (e.g. Sun, some BSD) use "-R" etc. This patch adds tests in configure for the three most common switches (to my best knowledge) which should cover all current platforms where Git is used.

Add --with-tcltk and --without-tcltk to configure. --with-tcltk enables the search of the Tcl/Tk interpreter. If no interpreter is found then Tcl/Tk dependend parts are disabled. --without-tcltk unconditionally disables Tcl/Tk dependent parts. The original behaviour is not changed: bare './configure' just installs the Tcl/Tk part doing no checks for the interpreter. Signed-off-by: Eygene Ryabinkin <rea-git@codelabs.ru>

configure.ac: rework/fix the NEEDS_RESOLV and NEEDS_LIBGEN tests The "action" parameters for these two tests were supplied incorrectly for the way the tests were implemented. The tests check whether a program which calls hstrerror() or basename() successfully links when -lresolv or -lgen are used, respectively. A successful linking would result in NEEDS_RESOLV or NEEDS_LIBGEN being unset, and failure would result in setting the respective variable. Aside from that issue, the tests did not handle the case where neither library was necessary for accessing the functions in question. So solve both of these issues by re-working the two tests so that their form is like the NEEDS_SOCKET test which attempts to link with just the c library, and if it fails then assumes that the additional library is necessary and sets the appropriate variable. Also an entry in the config.mak.in file is necessary for the NEEDS_LIBGEN variable to appear in the config.mak.autogen file with the value assigned by the configure script. Without it, the generated shell script would contain a snippet like this: for ac_lib in ; do ... which is incorrect.
