2015-10-21configure.ac: detect ssl need with libcurlLibravatar Remi Pommarel1-0/+10
When libcurl has been statically compiled with openssl support they both need to be linked in everytime libcurl is used. During configuration this can be detected by looking for Curl_ssl_init function symbol in libcurl, which will only be present if libcurl has been compiled statically built with openssl. configure.ac checks for Curl_ssl_init function in libcurl and if such function exists; it sets NEEDS_SSL_WITH_CURL that is used by the Makefile to include -lssl alongside with -lcurl.

2015-10-21Makefile: make curl-config path configurableLibravatar Remi Pommarel1-0/+13
There are situations, e.g. during cross compilation, where curl-config program is not present in the PATH. Make the makefile use a configurable curl-config program passed through CURL_CONFIG variable which can be set through config.mak. Also make this variable tunable through use of autoconf/configure. Configure will set CURL_CONFIG variable in config.mak.autogen to whatever value has been passed to ac_cv_prog_CURL_CONFIG.

2014-12-04compat: convert modes to use portable file type valuesLibravatar David Michael1-0/+23
This adds simple wrapper functions around calls to stat(), fstat(), and lstat() that translate the operating system's native file type bits to those used by most operating systems. It also rewrites the S_IF* macros to the common values, so all file type processing is performed using the translated modes. This makes projects portable across operating systems that use different file type definitions. Only the file type bits may be affected by these compatibility functions; the file permission bits are assumed to be 07777 and are passed through unchanged.

2014-03-27Portable alloca for GitLibravatar Kirill Smelkov1-0/+8
In the next patch we'll have to use alloca() for performance reasons, but since alloca is non-standardized and is not portable, let's have a trick with compatibility wrappers: 1. at configure time, determine, do we have working alloca() through alloca.h, and define #define HAVE_ALLOCA_H if yes. 2. in code #ifdef HAVE_ALLOCA_H # include <alloca.h> # define xalloca(size) (alloca(size)) # define xalloca_free(p) do {} while(0) #else # define xalloca(size) (xmalloc(size)) # define xalloca_free(p) (free(p)) #endif and use it like func() { p = xalloca(size); ... xalloca_free(p); } This way, for systems, where alloca is available, we'll have optimal on-stack allocations with fast executions. On the other hand, on systems, where alloca is not available, this gracefully fallbacks to xmalloc/free. Both autoconf and config.mak.uname configurations were updated. For autoconf, we are not bothering considering cases, when no alloca.h is available, but alloca() works some other way - its simply alloca.h is available and works or not, everything else is deep legacy. For config.mak.uname, I've tried to make my almost-sure guess for where alloca() is available, but since I only have access to Linux it is the only change I can be sure about myself, with relevant to other changed systems people Cc'ed. NOTE SunOS and Windows had explicit -DHAVE_ALLOCA_H in their configurations. I've changed that to now-common HAVE_ALLOCA_H=YesPlease which should be correct.

2012-12-19git-compat-util.h: do not #include <sys/param.h> by defaultLibravatar Junio C Hamano1-6/+0
Earlier we allowed platforms that lack <sys/param.h> not to include the header file from git-compat-util.h; we have included this header file since the early days back when we used MAXPATHLEN (which we no longer use) and also depended on it slurping ULONG_MAX (which we get by including stdint.h or inttypes.h these days). It turns out that we can compile our modern codebase just file without including it on many platforms (so far, Fedora, Debian, Ubuntu, MinGW, Mac OS X, Cygwin, HP-Nonstop, QNX and z/OS are reported to be OK). Let's stop including it by default, and on platforms that need it to be included, leave "make NEEDS_SYS_PARAM_H=YesPlease" as an escape hatch and ask them to report to us, so that we can find out about the real dependency and fix it in a more platform agnostic way.

2012-11-27configure.ac: fix pthreads detection on Mac OS XLibravatar Max Horn1-1/+11
The configure script checks whether certain flags are required to use pthreads. But it did not consider that *none* might be needed (as is the case on Mac OS X). This lead to configure adding "-mt" to the list of flags (which does nothing on OS X except producing a warning). This in turn triggered a compiler warning on every single file. To solve this, we now first check if pthreads work without extra flags. This means the check is now order dependant, hence a comment is added explaining this, and the reasons for it. Note that it might be possible to write an order independent test, but it does not seem worth the extra effort required for implementing and testing such a solution, when this simple solution exists and works.

2012-05-30docs: drop asciidoc7compatible flagLibravatar Jeff King1-7/+0
When we made the switch to supporting asciidoc 8 in 4c7100a (Documentation: adjust to AsciiDoc 8, 2007-06-14), we were able to leave most of the documentation intact by defining asciidoc7compatible. Since commit 6cf378f (docs: stop using asciidoc no-inline-literal, 2012-04-26), we don't support versions of asciidoc older than 8.4.1, which is when inline literals were introduced. Therefore there is not much point in keeping our documentation compatible with asciidoc 7. So we are now free to drop the asciidoc7compatible flag and update the documentation itself to assume asciidoc8. Fortunately, doing the latter is very easy; we weren't using any of the constructs impacted by asciidoc7compatible, so there are no changes to make. The reason is somewhat subtle. The asciidoc7compatible affects only super/sub-scripts ("^" and "~") and index terms. We don't use the latter at all. Nor we do we use the former, but we did have to protect them from accidental expansion in constructs like "rev^1". However, all of our uses of "~" and "^" are either in code blocks (which are rendered literally), or inside backticks. Prior to 6cf378f, backticks were not inline literals, and needed proper quoting. But post-6cf378f, we don't have to worry whether we are using the old or new rules, as those characters are not interpreted at all in either case. I verified that the result of "make install-html install-man" is identical before and after this patch on asciidoc 8.6.7.

2012-03-09configure: allow user to prevent $PATH "sanitization" on SolarisLibravatar Stefano Lattarini1-0/+17
On a Solaris 10 system with Solaris make installed as '/usr/xpg4/bin/make', GNU make installed as '/usr/local/bin/make', and with '/usr/local/bin' appearing in $PATH *before* '/usr/xpg4/bin', I was seeing errors like this upon invoking "make all": Usage : make [ -f makefile ][ -K statefile ]... make: Fatal error: Unknown option `-C' This happenes because the Git's Makefile, when running on Solaris, automatically "sanitizes" $PATH by prepending '/usr/xpg6/bin' and '/usr/xpg4/bin' to it in order to avoid using non-POSIX /bin/sh from being used. In the setup described above, however, this has an unintended consequence of forcing the use of Solaris make in recursive make invocations -- even if the $(MAKE) macro is being correctly used in them! When building without using the autoconf machinery, this can be solved by overriding $(SANE_TOOL_PATH). Teach the autoconf machinery to also allow users of ./configure to override it from the command line with a new --with-sane-tool-path option.

2011-12-05i18n: add infrastructure for translating Git with gettextLibravatar Ævar Arnfjörð Bjarmason1-0/+19
Change the skeleton implementation of i18n in Git to one that can show localized strings to users for our C, Shell and Perl programs using either GNU libintl or the Solaris gettext implementation. This new internationalization support is enabled by default. If gettext isn't available, or if Git is compiled with NO_GETTEXT=YesPlease, Git falls back on its current behavior of showing interface messages in English. When using the autoconf script we'll auto-detect if the gettext libraries are installed and act appropriately. This change is somewhat large because as well as adding a C, Shell and Perl i18n interface we're adding a lot of tests for them, and for those tests to work we need a skeleton PO file to actually test translations. A minimal Icelandic translation is included for this purpose. Icelandic includes multi-byte characters which makes it easy to test various edge cases, and it's a language I happen to understand. The rest of the commit message goes into detail about various sub-parts of this commit. = Installation Gettext .mo files will be installed and looked for in the standard $(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to override that, but that's only intended to be used to test Git itself. = Perl Perl code that's to be localized should use the new Git::I18n module. It imports a __ function into the caller's package by default. Instead of using the high level Locale::TextDomain interface I've opted to use the low-level (equivalent to the C interface) Locale::Messages module, which Locale::TextDomain itself uses. Locale::TextDomain does a lot of redundant work we don't need, and some of it would potentially introduce bugs. It tries to set the $TEXTDOMAIN based on package of the caller, and has its own hardcoded paths where it'll search for messages. I found it easier just to completely avoid it rather than try to circumvent its behavior. In any case, this is an issue wholly internal Git::I18N. Its guts can be changed later if that's deemed necessary. See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for a further elaboration on this topic. = Shell Shell code that's to be localized should use the git-sh-i18n library. It's basically just a wrapper for the system's gettext.sh. If gettext.sh isn't available we'll fall back on gettext(1) if it's available. The latter is available without the former on Solaris, which has its own non-GNU gettext implementation. We also need to emulate eval_gettext() there. If neither are present we'll use a dumb printf(1) fall-through wrapper. = About libcharset.h and langinfo.h We use libcharset to query the character set of the current locale if it's available. I.e. we'll use it instead of nl_langinfo if HAVE_LIBCHARSET_H is set. The GNU gettext manual recommends using langinfo.h's nl_langinfo(CODESET) to acquire the current character set, but on systems that have libcharset.h's locale_charset() using the latter is either saner, or the only option on those systems. GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either, but MinGW and some others need to use libcharset.h's locale_charset() instead. =Credits This patch is based on work by Jeff Epler <jepler@unpythonic.net> who did the initial Makefile / C work, and a lot of comments from the Git mailing list, including Jonathan Nieder, Jakub Narebski, Johannes Sixt, Erik Faye-Lund, Peter Krefting, Junio C Hamano, Thomas Rast and others.

2011-05-09configure: Check for libpcreLibravatar Michał Kiedrowicz1-0/+40
This patch adds checks for libpcre to configure. By default libpcre is disabled, --with-libpcre enables it (if it works). Signed-off-by: Michał Kiedrowicz <michal.kiedrowicz@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-03-28Improve test for pthreads flagLibravatar Giuseppe Bilotta1-0/+2
When compiling with CC=clang using Clang 1.1 as shipped by Debian unstable (package version 2.7-3), the -mt flag is sufficient to compile during the `configure` test. However, building git would then fail at link time complaining about missing symbols such as `pthread_key_create' and `pthread_create'. Work around this issue by adding pthread key creation to the pthreads configure test source.

2011-03-17unbreak and eliminate NO_C99_FORMATLibravatar Jonathan Nieder1-24/+0
In the spirit of v1.5.0.2~21 (Check for PRIuMAX rather than NO_C99_FORMAT in fast-import.c, 2007-02-20), use PRIuMAX from git-compat-util.h on all platforms instead of C99-specific formats like %zu with dangerous fallbacks to %u or %lu. So now C99-challenged platforms can build git without provoking warnings or errors from printf, even if pointers do not have the same size as an int or long. The need for a fallback PRIuMAX is detected in git-compat-util.h with "#ifndef PRIuMAX". So while at it, simplify the Makefile and configure script by eliminating the NO_C99_FORMAT knob altogether.

2011-02-14configure: use AC_LANG_PROGRAM consistentlyLibravatar Ralf Wildenhues1-37/+19
Avoid warnings from Autoconf 2.68 about missing use of AC_LANG_PROGRAM and friends. Quoting autoconf-2.68/NEWS: ** The macros AC_PREPROC_IFELSE, AC_COMPILE_IFELSE, AC_LINK_IFELSE, and AC_RUN_IFELSE now warn if the first argument failed to use AC_LANG_SOURCE or AC_LANG_PROGRAM to generate the conftest file contents. A new macro AC_LANG_DEFINES_PROVIDED exists if you have a compelling reason why you cannot use AC_LANG_SOURCE but must avoid the warning. The underlying reason for that change is that AC_LANG_{SOURCE,PROGRAM} take care to supply the previously computed set of #defines (and include standard headers if so desired) for preprocessed languages like C and C++. In some cases, AC_LANG_PROGRAM is already used but not sufficiently m4-quoted, so we just need to add another set of [quotes] to prevent the autoconf warning from being triggered bogusly. Quoting all arguments (except when calling special macros that need to be expanded before recursion) is better style, anyway. These and more rules are described in detail in 'info Autoconf "Programming in M4"'. No change in the resulting config.mak.autogen after running ./configure intended.
