This section gathers all the system libraries needed for xdm features. They may be in standard C library on some platforms and in discrete libraries on others.
Any xorg library is excluded from this section. XTRANS macros will be invoked at a later time and contribute additional libraries. Although a function is used to search for the library, this should not be confused with function checking (AC_CHECK_FUNC). Sample configuration output on GNU/Linux: checking for library containing getifaddrs... none required checking for library containing getspnam... none required checking for library containing setproctitle... no checking for library containing setusercontext... no checking for library containing pam_open_session... no checking for library containing is_selinux_enabled... -lselinux checking for library containing arc4random... -lbsd checking for library containing crypt... -lcrypt In the Makefile, libs are pre-pended: LIBS = -lcrypt -lbsd -lselinux Signed-off-by: Gaetan Nadon <[email protected]> --- =========== Second edition =========== Changed GNU/Linux to GNU systems Changed comment for the crypto library configure.ac | 35 +++++++++++++++++++++++++++++++++-- 1 files changed, 33 insertions(+), 2 deletions(-) diff --git a/configure.ac b/configure.ac index 72a08fd..7925ebc 100644 --- a/configure.ac +++ b/configure.ac @@ -53,6 +53,39 @@ XORG_WITH_LINT AC_PATH_PROG(MKTEMP_COMMAND, mktemp) AM_CONDITIONAL(HAVE_MKTEMP_COMMAND, test x$MKTEMP_COMMAND != x) +#------------------------------------------------------------------------------ +# Check for system libraries +# +# AC_SEARCH_LIBS: tests using $LIBS and tests again with each listed library. +# pre-pends the found library to $LIBS. +# +#------------------------------------------------------------------------------ +# Function getifaddrs comes from the C library or the name service library (nsl) +AC_SEARCH_LIBS([getifaddrs], [nsl]) + +# Function getspnam comes from the C library, Sysmtem V -lsec, UnixWare 7 -lgen +# or Old Linux versions -lshadow +AC_SEARCH_LIBS([getspnam], [sec gen shadow]) + +# Function setproctitle is in BSD -lutil or GNU systems -lbsd but N/A on Solaris +AC_SEARCH_LIBS([setproctitle], [util bsd]) + +# Function setusercontext is in BSD -lutil but N/A on Solaris or GNU systems +AC_SEARCH_LIBS([setusercontext], [util]) + +# Function pam_open_session is in -lpam +AC_SEARCH_LIBS([pam_open_session], [pam]) + +# Function is_selinux_enabled is in -lselinux +AC_SEARCH_LIBS(is_selinux_enabled, [selinux]) + +# Function arc4random is in BSD standard C or GNU systems -lbsd +AC_SEARCH_LIBS([arc4random], [bsd]) + +# The crypto library comes from OpenSSL +AC_SEARCH_LIBS(crypt, crypt) +#------------------------------------------------------------------------------ + m4_ifdef([AM_SILENT_RULES],[HAVE_AM_SILENT_RULES=yes]) AM_CONDITIONAL(HAVE_AM_SILENT_RULES, test x$HAVE_AM_SILENT_RULES != x) @@ -400,8 +433,6 @@ fi AM_CONDITIONAL(HAS_XDM_AUTH, test x$xdmauth = xyes -a x$xdmauth_enable != xno) -AC_SEARCH_LIBS(crypt, crypt) - AC_SUBST(XDM_CFLAGS) AC_SUBST(XDM_LIBS) -- 1.6.0.4 _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
