Re: [Libguestfs] [PATCH nbdkit v3] tests: Improve test for libc_malloc_debug

+dnl Does this platform have $libdir/libc_malloc_debug.so.0 (glibc >= +dnl 2.34)? We have to override the idiotic exec_prefix misfeature to +dnl get to the real libdir. +real_libdir="$( + if test "x$prefix" != xNONE; then + exec_prefix="$prefix" + else + exec_prefix="$ac_default_prefix" + fi + eval echo $libdir +)" +LIBC_MALLOC_DEBUG="$real_libdir/libc_malloc_debug.so.0" +AC_MSG_CHECKING([for $LIBC_MALLOC_DEBUG]) +AS_IF([test -r $LIBC_MALLOC_DEBUG], [ + have_libc_malloc_debug=yes + AC_SUBST([LIBC_MALLOC_DEBUG]) +],[have_libc_malloc_debug=no]) +AC_MSG_RESULT([$have_libc_malloc_debug]) +AM_CONDITIONAL([HAVE_LIBC_MALLOC_DEBUG], + [test "x$have_libc_malloc_debug" = xyes])
