From: Yogesh Prasad <yogesh.prasad () rockwellcollins com> Description This patch will correct the sequence of -pie and -shared options. When used together, -pie should be provided to the linker before -shared. If -pie is provided after -shared, the linker throws below error. ------------------------------------------------------------------------- /host/powerpc-buildroot-linux-gnu/sysroot/usr/lib/Scrt1.o:(.data+0x4): undefined reference to `main' /host/lib/gcc/powerpc-buildroot-linux-gnu/6.4.0/../../../../ powerpc-buildroot-linux-gnu/bin/ld: BFD (GNU Binutils) 2.28.1 assertion fail elf32-ppc.c:8923 collect2: error: ld returned 1 exit status make[2]: *** [libpcap.so] Error 1 make[1]: *** [/build/libpcap-1.8.1/.stamp_built] Error 2 make: *** [_all] Error 2 ------------------------------------------------------------------------- Signed-off-by: Yogesh Prasad <yogesh.prasad () rockwellcollins com> Signed-off-by: Matt Weber <matthew.weber () rockwellcollins com> --- Makefile.in | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/Makefile.in b/Makefile.in index e71d973..34b1097 100644 --- a/Makefile.in +++ b/Makefile.in @@ -371,7 +371,7 @@ libpcap.so: $(OBJ) @rm -f $@ VER=`cat $(srcdir)/VERSION`; \ MAJOR_VER=`sed 's/\([0-9][0-9]*\)\..*/\1/' $(srcdir)/VERSION`; \ - @V_SHLIB_CMD@ @V_SHLIB_OPT@ @V_SONAME_OPT@$@.$$MAJOR_VER $(LDFLAGS) \ + @V_SHLIB_CMD@ $(LDFLAGS) @V_SHLIB_OPT@ @V_SONAME_OPT@$@.$$MAJOR_VER \ -o $@.$$VER $(OBJ) $(ADDLOBJS) $(LIBS) # @@ -434,7 +434,7 @@ libpcap.sl: $(OBJ) # libpcap.shareda: $(OBJ) @rm -f $@ shr.o - $(CC) @V_SHLIB_OPT@ -o shr.o $(OBJ) $(ADDLOBJS) $(LDFLAGS) $(LIBS) + $(CC) $(LDFLAGS) @V_SHLIB_OPT@ -o shr.o $(OBJ) $(ADDLOBJS) $(LIBS) $(AR) rc $@ shr.o # -- 1.9.1 _______________________________________________ tcpdump-workers mailing list tcpdump-workers () lists tcpdump org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
