From 77c89f62f106d88ef2b5963f4a13755c337c793d Mon Sep 17 00:00:00 2001 From: Fabrice Fontaine Date: Mon, 15 Feb 2021 07:56:29 +0100 Subject: [PATCH] configure.ac: fix build without threads Cross-compilation of libgpg-error fails on toolchain without threads since commit 988211d3d4c1f3d5cfa6b460210f65ab636763b5, 9ee011259f819a3cf50fe7019fa4366dbc437e0e and 50e62b36ea01ed25d12c443088b85d4f41a2b3e1 Indeed, since that time, libgpg-error assumes that pthread.h is always available resulting in the following error at configure time: checking for arm-unknown-linux-gnueabi-objdump... (cached) /tmp/instance-1/output-1/host/bin/arm-linux-objdump conftest.c:1:10: fatal error: pthread.h: No such file or directory 1 | #include | ^~~~~~~~~~~ compilation terminated. configure: generated src/lock-obj-pub.native.h using arm-unknown-linux-gnueabi-objdump and gawk checking whether to enable log_clock... no This error will in turn results in a build failure because "Can't determine mutex size" is echoed by gen-lock-obj.sh: In file included from strsource-sym.c:27: ./gpg-error.h:1115:4: warning: missing terminating ' character 1115 | Can't determine mutex size | ^ Full build log: http://autobuild.buildroot.org/results/334/3344c96e5627a9327b0eabe0b27f34490bbabc0d/build-end.log Signed-off-by: Fabrice Fontaine [Upstream status: https://dev.gnupg.org/T5296] --- configure.ac | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/configure.ac b/configure.ac index b9a2a3e..15d9fdc 100644 --- a/configure.ac +++ b/configure.ac @@ -599,7 +599,7 @@ if test x$cross_compiling = xyes; then case $host in *-*-linux*) AC_CHECK_TOOL(OBJDUMP, [objdump]) - if test -n "$OBJDUMP"; then + if test -n "$OBJDUMP" -a x"$gl_use_threads" != xno; then lock_obj_h_generated=yes if test ! -d src; then mkdir src; fi LOCK_ABI_VERSION=1 host=$host host_alias=$host_alias \ -- 2.30.0
