- 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 <pthread.h>
- | ^~~~~~~~~~~
- 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
- | ^
