From 0090089f8fb9661d5a97d6300388b6b005e35ac8 Mon Sep 17 00:00:00 2001 From: Alexandre Vassalotti Date: Fri, 17 Jul 2009 05:26:39 +0000 Subject: Cache the results of all runtime checks. This will be helpful to people who want to compile Python with a cross-compiler. Now you can upload the configure script on your host machine, run it with caching enabled, and download the cached results on your build machine. --- configure.in | 101 +++++++++++++++++++++++++++++++++++++---------------------- 1 file changed, 64 insertions(+), 37 deletions(-) diff --git a/configure.in b/configure.in index 0e193a2..e235ebd 100644 --- a/configure.in +++ b/configure.in @@ -918,10 +918,11 @@ yes) AC_MSG_CHECKING(whether $CC accepts -fno-strict-aliasing) ac_save_cc="$CC" CC="$CC -fno-strict-aliasing" + AC_CACHE_VAL(ac_cv_no_strict_aliasing_ok, AC_TRY_RUN([int main() { return 0; }], ac_cv_no_strict_aliasing_ok=yes, ac_cv_no_strict_aliasing_ok=no, - ac_cv_no_strict_aliasing_ok=no) + ac_cv_no_strict_aliasing_ok=no)) CC="$ac_save_cc" AC_MSG_RESULT($ac_cv_no_strict_aliasing_ok) if test $ac_cv_no_strict_aliasing_ok = yes @@ -2589,6 +2590,7 @@ AC_CHECK_LIB(c, inet_aton, [$ac_cv_prog_TRUE], # On Tru64, chflags seems to be present, but calling it will # exit Python AC_MSG_CHECKING(for chflags) +AC_CACHE_VAL(ac_cv_have_chflags, AC_TRY_RUN([ #include #include @@ -2598,12 +2600,18 @@ int main(int argc, char*argv[]) return 1; return 0; } -],AC_DEFINE(HAVE_CHFLAGS, 1, Define to 1 if you have the `chflags' function.) - AC_MSG_RESULT(yes), - AC_MSG_RESULT(no) +], ac_cv_have_chflags=yes, + ac_cv_have_chflags=no, + ac_cv_have_chflags=no) ) +AC_MSG_RESULT($ac_cv_have_chflags) +if test $ac_cv_have_chflags = yes +then + AC_DEFINE(HAVE_CHFLAGS, 1, Define to 1 if you have the `chflags' function.) +fi AC_MSG_CHECKING(for lchflags) +AC_CACHE_VAL(ac_cv_have_lchflags, AC_TRY_RUN([ #include #include @@ -2613,10 +2621,15 @@ int main(int argc, char*argv[]) return 1; return 0; } -],AC_DEFINE(HAVE_LCHFLAGS, 1, Define to 1 if you have the `lchflags' function.) - AC_MSG_RESULT(yes), - AC_MSG_RESULT(no) +], ac_cv_have_lchflags=yes, + ac_cv_have_lchflags=no, + ac_cv_have_lchflags=no) ) +AC_MSG_RESULT($ac_cv_have_lchflags) +if test $ac_cv_have_lchflags = yes +then + AC_DEFINE(HAVE_LCHFLAGS, 1, Define to 1 if you have the `lchflags' function.) +fi dnl Check if system zlib has *Copy() functions dnl @@ -2770,19 +2783,22 @@ AC_TRY_LINK([ #include #include #include -],[ -getaddrinfo(NULL, NULL, NULL, NULL); -], [ -AC_MSG_RESULT(yes) -AC_MSG_CHECKING(getaddrinfo bug) -AC_TRY_RUN([ +], [getaddrinfo(NULL, NULL, NULL, NULL);], +have_getaddrinfo=yes, +have_getaddrinfo=no) +AC_MSG_RESULT($have_getaddrinfo) +if test $have_getaddrinfo = yes +then + AC_MSG_CHECKING(getaddrinfo bug) + AC_CACHE_VAL(ac_cv_buggy_getaddrinfo, + AC_TRY_RUN([[ #include #include #include #include #include -main() +int main() { int passive, gaierr, inet4 = 0, inet6 = 0; struct addrinfo hints, *ai, *aitop; @@ -2854,26 +2870,22 @@ main() if (aitop) freeaddrinfo(aitop); - exit(0); + return 0; bad: if (aitop) freeaddrinfo(aitop); - exit(1); + return 1; } -], -AC_MSG_RESULT(good) -buggygetaddrinfo=no, -AC_MSG_RESULT(buggy) -buggygetaddrinfo=yes, -AC_MSG_RESULT(buggy) -buggygetaddrinfo=yes)], [ -AC_MSG_RESULT(no) -buggygetaddrinfo=yes -]) +]], ac_cv_buggy_getaddrinfo=no, + ac_cv_buggy_getaddrinfo=yes, + ac_cv_buggy_getaddrinfo=yes)) +fi -if test "$buggygetaddrinfo" = "yes"; then - if test "$ipv6" = "yes"; then +if test $have_getaddrinfo = no -o $ac_cv_buggy_getaddrinfo = yes +then + if test $ipv6 = yes + then echo 'Fatal: You must get working getaddrinfo() function.' echo ' or you can specify "--disable-ipv6"'. exit 1 @@ -3205,6 +3217,7 @@ fi # Multiprocessing check for broken sem_getvalue AC_MSG_CHECKING(for broken sem_getvalue) +AC_CACHE_VAL(ac_cv_broken_sem_getvalue, AC_TRY_RUN([ #include #include @@ -3225,11 +3238,16 @@ int main(void){ sem_close(a); return res==-1 ?
