Unfortunately it looks like this could cause some problems when bootstrapping a new toolchain. If the libc.so script references libubacktrace, but libubacktrace.so.0 is not yet installed anywhere, gcc will throw an error during the final link on the other shared libraries: rm -f lib/libdl.so lib/libdl.so.0 lib/libdl-0.9.32.1.so arm-linux-uclibcgnueabi-gcc -Wl,-EL -shared -Wl,--warn-common -Wl,--warn-once -Wl,-z,combreloc -Wl,-z,relro -Wl,-z,defs -Wl,-fini,dl_cleanup -Wl,-soname=libdl.so.0 -nostdlib -o lib/libdl-0.9.32.1.so -Wl,--whole-archive ldso/libdl/libdl_so.a -Wl,--no-whole-archive ./lib/interp.os -L./lib ./lib/libc.so ./lib/ld-uClibc.so.0 /ssd/test/bin/../lib/gcc/arm-linux-uclibcgnueabi/4.5.3/libgcc.a /ssd/test/bin/../lib/gcc/arm-linux-uclibcgnueabi/4.5.3/libgcc_eh.a /ssd/test/bin/../lib/gcc/arm-linux-uclibcgnueabi/4.5.3/../../../../arm-linux-uclibcgnueabi/bin/ld: cannot find libubacktrace.so.0 collect2: ld returned 1 exit status make[1]: *** [lib/libdl.so] Error 1 I did not see this earlier because -nostdlib doesn't actually keep gcc from passing ld "-L" arguments pointing into the sysroot directories. So it saw my existing libubacktrace.so.0 from the installed sysroot and did not complain that libubacktrace.so.0 was missing from the uClibc build tree. Maybe we will need to revert back to this technique, at least in some form? -# Add the AS_NEEDED entry for libubacktrace.so - if [ -f $(top_builddir)lib/libc.so -a -f $(PREFIX)$(RUNTIME_PREFIX)$(MULTILIB_DIR)/$(SHARED_LIBNAME) ] ; then \ - echo "GROUP ( $(UBACKTRACE_ASNEEDED) )" >> $(PREFIX)$(DEVEL_PREFIX)$(MULTILIB_DIR)/libc.so; \ - fi -endif I would appreciate any feedback/suggestions. _______________________________________________ uClibc mailing list uClibc@uclibc.org http://lists.busybox.net/mailman/listinfo/uclibc
