While trying to build m4.git with clang on a Fedora 40 machine, and with gnulib updated to the latest git commit, I'm hitting the following during 'make check' (building with gcc worked):
CC test-gettimeofday.o CCLD test-gettimeofday /usr/bin/ld: test-gettimeofday.o: in function `main': /home/eblake/m4-tmp/tests/test-gettimeofday.c:44:(.text+0x46): undefined reference to `rpl_gettimeofday' /usr/bin/ld: /home/eblake/m4-tmp/tests/test-gettimeofday.c:60:(.text+0x6c): undefined reference to `rpl_gettimeofday' /usr/bin/ld: /home/eblake/m4-tmp/tests/test-gettimeofday.c:62:(.text+0x8a): undefined reference to `rpl_gettimeofday' /usr/bin/ld: libtests.a(time.o): in function `rpl_time': /home/eblake/m4-tmp/tests/time.c:33:(.text+0xe): undefined reference to `rpl_gettimeofday' clang: error: linker command failed with exit code 1 (use -v to see invocation) make[5]: *** [Makefile:6925: test-gettimeofday] Error 1 Grepping build logs shows: config.log: ac_cv_func_gettimeofday=yes gl_cv_func_gettimeofday_posix_signature=yes GL_COND_OBJ_GETTIMEOFDAY_FALSE='' GL_COND_OBJ_GETTIMEOFDAY_TRUE='#' GL_M4_GNULIB_GETTIMEOFDAY='IN_M4_GNULIB_TESTS' HAVE_GETTIMEOFDAY='1' REPLACE_GETTIMEOFDAY='0' #define HAVE_GETTIMEOFDAY 1 #define GETTIMEOFDAY_TIMEZONE void #define GNULIB_TEST_GETTIMEOFDAY 1 Makefile.in: GL_M4_GNULIB_GETTIMEOFDAY = @GL_M4_GNULIB_GETTIMEOFDAY@ HAVE_GETTIMEOFDAY = @HAVE_GETTIMEOFDAY@ REPLACE_GETTIMEOFDAY = @REPLACE_GETTIMEOFDAY@ Makefile: GL_M4_GNULIB_GETTIMEOFDAY = IN_M4_GNULIB_TESTS HAVE_GETTIMEOFDAY = 1 REPLACE_GETTIMEOFDAY = 0 Is this a case of a missing LDFLAGS in m4's tests/Makefile.am (which right now only includes gnulib.mk) or top-level Makefile.am? Or is it a gnulib problem? -- Eric Blake, Principal Software Engineer Red Hat, Inc. Virtualization: qemu.org | libguestfs.org
