Hi,the next [patch 3/5] will change the libcc1.so API. I am not sure if the API change gets approved that way but for such case: (1) We really need to change GCC_FE_VERSION_0 -> GCC_FE_VERSION_1, this feature is there for this purpose. That is [patch 2/5]. (2) Currently GDB does only dlopen("libcc1.so") and then depending on which libcc1.so version it would find first it would succeed/fail. I guess it is more convenient to do dlopen("libcc1.so.1") instead (where ".1"=".x" corresponds to GCC_FE_VERSION_x). That is this patch (with x=0). GCC_C_FE_LIBCC is used only by GDB. (3) Currently there is no backward or forward compatibility although there could be one implemented. Personally I think the 'compile' feature is still in experimental stage so that it is OK to require last releases. At least in Fedora we can keep GDB<->GCC in sync. GDB counterpart: [PATCH 1/4] compile: Use libcc1.so->libcc1.so.0 https://sourceware.org/ml/gdb-patches/2015-04/msg00805.html Message-ID: <20150421213635.14147.15653.st...@host1.jankratochvil.net> Jan include/ChangeLog 2015-04-21 Jan Kratochvil <jan.kratoch...@redhat.com> * gcc-c-interface.h (GCC_C_FE_LIBCC): Quote it. Append GCC_FE_VERSION_0.
OK. Please install on the trunk. jeff
