GCC bootstrap build error with openembedded/v8 model
Hi all, I am facing build error, when I try to bootstrap GCC trunk for native aarch64-unknown-linux-gnu configuration in openemedded/V8 model. Linker error occurs while building stage 1 GCC. (Snip) /usr/lib/gcc/aarch64-oe-linux/4.7.3/../../../../aarch64-oe-linux/bin/ld: gcov: hidden symbol `__deregister_frame_info' in /usr/lib/gcc/aarch64-oe-linux/4.7.3/../../../aarch64-oe-linux/4.7.3/libgcc_eh.a(unwind-dw2-fde-dip.o) is referenced by DSO /usr/lib/gcc/aarch64-oe-linux/4.7.3/../../../../aarch64-oe-linux/bin/ld: final link failed: Bad value collect2: error: ld returned 1 exit status (Snip) The steps to reproduce the issue is attached. Need some help to solve this. regards, Venkat. Below are the steps to reproduce: Step 1 -- Download the openembedded image and resize it by adding ~10GB. Steps to do that is described here. https://wiki.linaro.org/WorkingGroups/ToolChain/IncreaseImageSize I used latest image "vexpress64-openembedded_lamp-armv8_20130526-344.img" at http://www.linaro.org/engineering/armv8 Step 2 -- Check out GCC trunk svn checkout svn://gcc.gnu.org/svn/gcc/trunk gcc199474 I used trunk revision 199474 Step 3 -- Mount and copy GCC source to /home/root sudo mount -o loop,offset=54525952 -t ext4 vexpress64-openembedded_lamp-armv8_20130526-344.img /mnt/temp2 copy the source to /mnt/temp2/home/root Step 4 -- Start the V8 model and boot openembedded image ./Foundation_v8pkg/Foundation_v8 --image img-foundation.axf --block-device vexpress64-openembedded_lamp-armv8_20130526-344.img --network=nat --network-nat-ports=8022=22 Step 5 --- In the xterm window go to /home/root, create a build directory, configure and run make. mkdir build cd build ../gcc199474/configure --enable-languages=c,c++ --disable-threads --disable-libssp --disable-libgomp --disable-libmudflap --disable-libatomic --without-libquadmath --disable-libquadmath --prefix=/home/root/install make ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain

Re: GCC bootstrap build error with openembedded/v8 model
Hi Renato, Thanks for helping out. I need to explictly link against libgcc_eh.a GCOV_OBJS = gcov.o gcov$(exeext): $(GCOV_OBJS) $(LIBDEPS) +$(LINKER) $(ALL_LINKERFLAGS) $(LDFLAGS) $(GCOV_OBJS) $(LIBS) -lgcc_eh -o $@ GCOV_DUMP_OBJS = gcov-dump.o gcov-dump$(exeext): $(GCOV_DUMP_OBJS) $(LIBDEPS) +$(LINKER) $(ALL_LINKERFLAGS) $(LDFLAGS) $(GCOV_DUMP_OBJS) \ $(LIBS) -lgcc_eh -o $@ Build crossed that error point now. regards, Venkat.
