( https://gerrit.osmocom.org/c/libosmo-sccp/+/17791 ) Change subject: configure.ac: fix libtool issue with clang and sanitizer ...................................................................... configure.ac: fix libtool issue with clang and sanitizer As pointed out at https://github.com/libexpat/libexpat/issues/312 libtool does not play nice with clang sanitizer builds at all. For those builds LD shoud be set to clang too (and LDFLAGS needs the sanitizer flags as well), because the clang compiler driver knows how linking to the sanitizer libs works, but then at a later stage libtool fails to actually produce the shared libraries and the build fails. This is fixed by this patch. Addtionally LD_LIBRARY_PATH has no effect on conftest runs during configure time, so the rpath needs to be set to the asan library path to ensure the configure run does not fail due to a missing asan library, i.e.: SANS='-fsanitize=memory -fsanitize-recover=all -shared-libsan' export CC=clang-10 ASANPATH=$(dirname `$CC -print-file-name=libclang_rt.asan-x86_64.so`) export LDFLAGS="-Wl,-rpath,$ASANPATH $SANS $LDFLAGS" Change-Id: I292c303840a76c5042dc077829c5df46158ca8ba --- M configure.ac 1 file changed, 5 insertions(+), 0 deletions(-) Approvals: laforge: Looks good to me, approved Jenkins Builder: Verified diff --git a/configure.ac b/configure.ac index 9cf517a..fdd6941 100644 --- a/configure.ac +++ b/configure.ac @@ -22,6 +22,11 @@ AC_PROG_INSTALL LT_INIT +dnl patching ${archive_cmds} to affect generation of file "libtool" to fix linking with clang +AS_CASE(["$LD"],[*clang*], + [AS_CASE(["${host_os}"], + [*linux*],[archive_cmds='$CC -shared $pic_flag $libobjs $deplibs $compiler_flags $wl-soname $wl$soname -o $lib'])]) + dnl check for pkg-config (explained in detail in libosmocore/configure.ac) AC_PATH_PROG(PKG_CONFIG_INSTALLED, pkg-config, no) if test "x$PKG_CONFIG_INSTALLED" = "xno"; then -- To view, visit https://gerrit.osmocom.org/c/libosmo-sccp/+/17791 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: libosmo-sccp Gerrit-Branch: master Gerrit-Change-Id: I292c303840a76c5042dc077829c5df46158ca8ba Gerrit-Change-Number: 17791 Gerrit-PatchSet: 3 Gerrit-Owner: Hoernchen <ewild at sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge at osmocom.org> Gerrit-MessageType: merged -------------- next part -------------- An HTML attachment was scrubbed...
