From e684939559341cb1c6373dfc6469b59e580d80af Mon Sep 17 00:00:00 2001 From: Changqing Li Date: Wed, 3 Jun 2020 13:39:18 +0800 Subject: [PATCH] Makefile.am: fixup issue #17 only make $(LIBOBJS) depend on $(LTLIBOBJS) still have race condition, library like pidfile.o may be changed when compile or link for target libsyslog_la_LIBADD, which will cause problem like below: ERROR: dwarfsrcfiles failed with exit code 1 (cmd was ['dwarfsrcfiles', /tmp/work/ppc7400-oe-linux/sysklogd/2.1.2-r0/package/usr/lib/libsyslog.a']): dwarfsrcfiles: tmp/work/ppc7400-oe-linux/sysklogd/2.1.2-r0/package/usr/lib/libsyslog.a: not a valid ELF file arm-oe-linux-gnueabi-libtool: link: arm-oe-linux-gnueabi-gcc -march=armv7ve -mthumb -mfpu=neon -mfloat-abi=hard --sysroot=TOPDIR/tmp-glibc/work/armv7vet2hf-neon-oe-linux-gnueabi/sysklogd/2.1.2-r0/recipe-sysroot -shared -fPIC -DPIC .libs/libsyslog_la-syslog.o ../lib/.libs/pidfile.o ../lib/.libs/strlcpy.o ../lib/.libs/strlcat.o -march=armv7ve -mthumb -mfpu=neon -mfloat-abi=hard --sysroot=TOPDIR/tmp-glibc/work/armv7vet2hf-neon-oe-linux-gnueabi/sysklogd/2.1.2-r0/recipe-sysroot -O2 -g -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed -Wl,-soname -Wl,libsyslog.so.0 -o .libs/libsyslog.so.0.0.0 arm-oe-linux-gnueabi-libtool: link: (cd ".libs" && rm -f "libsyslog.so.0" && ln -s "libsyslog.so.0.0.0" "libsyslog.so.0") arm-oe-linux-gnueabi-libtool: link: (cd ".libs" && rm -f "libsyslog.so" && ln -s "libsyslog.so.0.0.0" "libsyslog.so") arm-oe-linux-gnueabi-libtool: link: arm-oe-linux-gnueabi-gcc-ar cru .libs/libsyslog.a libsyslog_la-syslog.o ../lib/pidfile.o ../lib/strlcpy.o ../lib/strlcat.o TOPDIR/tmp-glibc/work/armv7vet2hf-neon-oe-linux-gnueabi/sysklogd/2.1.2-r0/recipe-sysroot-native/usr/bin/arm-oe-linux-gnueabi/../../libexec/arm-oe-linux-gnueabi/gcc/arm-oe-linux-gnueabi/10.1.0/ar: `u' modifier ignored since `D' is the default (see `U') TOPDIR/tmp-glibc/work/armv7vet2hf-neon-oe-linux-gnueabi/sysklogd/2.1.2-r0/recipe-sysroot-native/usr/bin/arm-oe-linux-gnueabi/../../libexec/arm-oe-linux-gnueabi/gcc/arm-oe-linux-gnueabi/10.1.0/ar: ../lib/strlcat.o: No such file or directory Signed-off-by: Changqing Li --- src/Makefile.am | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/src/Makefile.am b/src/Makefile.am index f8a6820..9b80a02 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -66,6 +66,7 @@ libsyslog_la_LIBADD = $(LTLIBOBJS) # ld: syslogd-syslogd.o: in function `main': syslogd.c:417: undefined # reference to `__pidfile' # -# Work around the problem by building one .o from lib at a time, this -# can be achieved by making LIBOBJS depend on LTLIBOBJS. -$(LIBOBJS): $(LTLIBOBJS) +# Work around the problem by make LIBOBJS depend on libsyslog.la, +# so that LIBOBJS/syslogd/logger will start compile after libsyslog.la +# is completed +$(LIBOBJS): $(lib_LTLIBRARIES)
