Hi, I'm maintaining Ceph in Debian. That's probably the only distro where we have a mips64el port. And it fails there: https://buildd.debian.org/status/package.php?p=ceph&suite=experimental (click on the "Build-Attempted" to see the build log in front of mips64el) This CPU doesn't support atomic operations, so it must use the emulation provided by the lib atomic. So "-latomic" should be added to the command line. I've first tried to add in debian/rules: DEB_LDFLAGS_MAINT_APPEND=-latomic but this puts -latomic at the beginning of the command line, before the Ceph internal .so, which fails. So I tried another approach which was to patch the CMakeLists.txt: --- ceph-16.2.6+ds.orig/src/tools/rbd_mirror/CMakeLists.txt +++ ceph-16.2.6+ds/src/tools/rbd_mirror/CMakeLists.txt @@ -71,6 +71,7 @@ add_library(rbd_mirror_internal STATIC add_executable(rbd-mirror main.cc) target_link_libraries(rbd-mirror + atomic rbd_mirror_internal rbd_mirror_types rbd_api --- a/src/mgr/CMakeLists.txt 2021-11-03 11:57:18.576976453 +0100 +++ b/src/mgr/CMakeLists.txt 2021-11-21 22:46:46.353082042 +0100 @@ -37,7 +37,8 @@ osdc client heap_profiler global-static ceph-common Boost::python${MGR_PYTHON_VERSION_MAJOR}${MGR_PYTHON_VERSION_MINOR} - Python3::Python ${CMAKE_DL_LIBS} ${GSSAPI_LIBRARIES}) + Python3::Python ${CMAKE_DL_LIBS} ${GSSAPI_LIBRARIES} + atomic) set_target_properties(ceph-mgr PROPERTIES POSITION_INDEPENDENT_CODE ${EXE_LINKER_USE_PIE}) install(TARGETS ceph-mgr DESTINATION bin) This worked for the libs, but failed when building rbd_mirror binary. So my question is: what's the best way, for a Debian package, to make Ceph add -latomic *AT THE END* of the command line? As for the mipsel arch, the error is: virtual memory exhausted: Cannot allocate memory so I'd need to save some memory at build time, somehow. Tips would be appreciated. For armel, the issue is: /tmp/cc3CvITT.s:2594: Error: selected processor does not support `yield' in ARM mode Does anyone know how to fix that? Thanks in advance for anyone who will help, Cheers, Thomas Goirand (zigo) _______________________________________________ Dev mailing list -- dev@xxxxxxx To unsubscribe send an email to dev-leave@xxxxxxx
