Description: This patch is needed in situations where build system is running same version of binutils that is intended to be built cross-native ( build != host = target) and has shared libraries enabled. binutils/binutils Makefile has some tools which are built to run on build system. Toplevel makefile for binutils passes HOST_EXPORTS to sub-makefiles which also include RPATH_ENVVARS containing LD_LIBRARY_PATH which is modified so that it also includes host libraries like opcodes and libbfd which are just built for the host system. Now the problem is that same LD_LIBRARY_PATH value gets set in environment even for the tools that are being built for build system using CC_FOR_BUILD and the tools like as,ld it invokes from build machine get the LD_LIBRARY_PATH set to search the newly build host libraries like opcodes and bfd and if host is like a big endian system say (mips-linux) the build system linker and assembler do not run because ld.so tries to load these shared libraries instead of the ones from /usr/lib for the build tools. This patch fixes the issue by clearing LD_LIBRARY_PATH for BUILD tools This patch would be needed on other versions of binutils. I just cared about 2.20 May be upstream is also interested in such a patch. -Khem Index: binutils-2.20/binutils/Makefile.am =================================================================== --- binutils-2.20.orig/binutils/Makefile.am 2009-12-30 15:30:35.302438121 -0800 +++ binutils-2.20/binutils/Makefile.am 2009-12-30 15:33:09.154420373 -0800 @@ -251,24 +251,24 @@ sysroff.h: sysinfo$(EXEEXT_FOR_BUILD) sy ./sysinfo$(EXEEXT_FOR_BUILD) -d <$(srcdir)/sysroff.info >sysroff.h sysinfo$(EXEEXT_FOR_BUILD): sysinfo.o syslex.o - $(CC_FOR_BUILD) $(CFLAGS_FOR_BUILD) $(LDFLAGS_FOR_BUILD) -o $@ sysinfo.o syslex.o + LD_LIBRARY_PATH= $(CC_FOR_BUILD) $(CFLAGS_FOR_BUILD) $(LDFLAGS_FOR_BUILD) -o $@ sysinfo.o syslex.o syslex.o: syslex.c sysinfo.h config.h if [ -r syslex.c ]; then \ - $(CC_FOR_BUILD) -c -I. $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) syslex.c -Wno-error ; \ + LD_LIBRARY_PATH= $(CC_FOR_BUILD) -c -I. $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) syslex.c -Wno-error ; \ else \ - $(CC_FOR_BUILD) -c -I. -I$(srcdir) $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) $(srcdir)/syslex.c -Wno-error ;\ + LD_LIBRARY_PATH= $(CC_FOR_BUILD) -c -I. -I$(srcdir) $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) $(srcdir)/syslex.c -Wno-error ;\ fi sysinfo.o: sysinfo.c if [ -r sysinfo.c ]; then \ - $(CC_FOR_BUILD) -c -I. $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) sysinfo.c -Wno-error ; \ + LD_LIBRARY_PATH= $(CC_FOR_BUILD) -c -I. $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) sysinfo.c -Wno-error ; \ else \ - $(CC_FOR_BUILD) -c -I. $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) $(srcdir)/sysinfo.c -Wno-error ; \ + LD_LIBRARY_PATH= $(CC_FOR_BUILD) -c -I. $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) $(srcdir)/sysinfo.c -Wno-error ; \ fi bin2c$(EXEEXT_FOR_BUILD): - $(CC_FOR_BUILD) -o $@ $(AM_CPPFLAGS) $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) $(LDFLAGS_FOR_BUILD) $(srcdir)/bin2c.c $(srcdir)/version.c + LD_LIBRARY_PATH= $(CC_FOR_BUILD) -o $@ $(AM_CPPFLAGS) $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) $(LDFLAGS_FOR_BUILD) $(srcdir)/bin2c.c $(srcdir)/version.c embedspu: embedspu.sh sed "s@^program_transform_name=@program_transform_name=$(program_transform_name)@" < $< > $@ Index: binutils-2.20/binutils/Makefile.in =================================================================== --- binutils-2.20.orig/binutils/Makefile.in 2009-12-30 15:30:44.582922535 -0800 +++ binutils-2.20/binutils/Makefile.in 2009-12-30 15:33:47.322422313 -0800 @@ -1193,24 +1193,24 @@ sysroff.h: sysinfo$(EXEEXT_FOR_BUILD) sy ./sysinfo$(EXEEXT_FOR_BUILD) -d <$(srcdir)/sysroff.info >sysroff.h sysinfo$(EXEEXT_FOR_BUILD): sysinfo.o syslex.o - $(CC_FOR_BUILD) $(CFLAGS_FOR_BUILD) $(LDFLAGS_FOR_BUILD) -o $@ sysinfo.o syslex.o + LD_LIBRARY_PATH= $(CC_FOR_BUILD) $(CFLAGS_FOR_BUILD) $(LDFLAGS_FOR_BUILD) -o $@ sysinfo.o syslex.o syslex.o: syslex.c sysinfo.h config.h if [ -r syslex.c ]; then \ - $(CC_FOR_BUILD) -c -I. $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) syslex.c -Wno-error ; \ + LD_LIBRARY_PATH= $(CC_FOR_BUILD) -c -I. $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) syslex.c -Wno-error ; \ else \ - $(CC_FOR_BUILD) -c -I. -I$(srcdir) $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) $(srcdir)/syslex.c -Wno-error ;\ + LD_LIBRARY_PATH= $(CC_FOR_BUILD) -c -I. -I$(srcdir) $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) $(srcdir)/syslex.c -Wno-error ;\ fi sysinfo.o: sysinfo.c if [ -r sysinfo.c ]; then \ - $(CC_FOR_BUILD) -c -I. $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) sysinfo.c -Wno-error ; \ + LD_LIBRARY_PATH= $(CC_FOR_BUILD) -c -I. $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) sysinfo.c -Wno-error ; \ else \ - $(CC_FOR_BUILD) -c -I. $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) $(srcdir)/sysinfo.c -Wno-error ; \ + LD_LIBRARY_PATH= $(CC_FOR_BUILD) -c -I. $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) $(srcdir)/sysinfo.c -Wno-error ; \ fi bin2c$(EXEEXT_FOR_BUILD): - $(CC_FOR_BUILD) -o $@ $(AM_CPPFLAGS) $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) $(LDFLAGS_FOR_BUILD) $(srcdir)/bin2c.c $(srcdir)/version.c + LD_LIBRARY_PATH= $(CC_FOR_BUILD) -o $@ $(AM_CPPFLAGS) $(AM_CFLAGS) $(CFLAGS_FOR_BUILD) $(LDFLAGS_FOR_BUILD) $(srcdir)/bin2c.c $(srcdir)/version.c embedspu: embedspu.sh sed "s@^program_transform_name=@program_transform_name=$(program_transform_name)@" < $< > $@
