I've now done just that: * build top of gcc-11 with --enable-languages=d --enable-libphobos * use that as bootstrap gdc for master Results are pretty good: * The corrupted *.Po files in stage1 are gone. * On 10.7, the d21 SEGV is gone * gdc and libphobos testsuite results on both 10.7 and 12 are reasonable. There's one caveat, though: On 10.7 (so far), a couple of files don't compile building stage2 libphobos: dyld: Symbol not found: __D6object10_xopEqualsFxPvxQdZb Referect10_xopEqualsFxPvxQdZb Referenced from: /var/gcc/regression/mnced from: /var/gcc/regression/master/10.7-gcc/build/./gcc/d21 Expected in: /var/gcc/regression/master/10.7-gcc/build/x86_64-apple-darwin11.4.2/libphobos/src/.libs/libgphobos.2.dylib in /var/gcc/regression/master/10.7-gcc/gcc/regression/master/10.7-gcc/build/./gcc/d21 and indeed that symbol (object._xopEquals(const(void*), const(void*))) is missing from the freshly built libgphobos, while it is present in the gcc-11 one. I suspect this happens because the toplevel Makefile sets DYLD_LIBRARY_PATH, since when I just run make in x86_64-apple-darwin11.4.2/libphobos, the build succeeds without further problems. There are two issues here, I believe: * The one line patch to gcc/config/darwin.h to support -static-libphobos should be backported to the gcc-11 branch to avoid this in the first place. * Besides, making incompatible changes to libgphobos (like removing an exported interface) shouldn't be done without increasing the library version number.
