This actually allowed me to get LLVM to build properly. My PR checks here shows error but that is only due to caching github-action current caching. Otherwise works as expected to build out a development package https://github.com/SynoCommunity/spksrc/pull/5225 So far I got all I need with the exception of gcc ... > I simply edited the by-configure-produced Makefile via removing all the > requisites to build libsanitizer. Then everything continued as expected. I really wonder what you did in here to get this going in order to prevent it to build as it is referred everywhere in there? I could script this if you can provide me a few additional pointers. In the meantime I tried variations on the --enable-libsanitizer or --disable-libsanitizer or --disable-libiberty all together... all failing one way or another. > Probably I will rebuild the toolchain from sources again, removing the > '--enable-libsanitizer' in the configure command.

Similar to what I did for LLVM where v9 builds ok from toolchain provided gcc-4.9 for Synology DSM 6.x and LLVM latest (v16) builds fine using toolchain provided gcc-8.5 for Synology DSM 7.x. > The options were copied "selectively" from the original gcc-8.5.0 in the > Synology toolchain > (for a x86_64 host). The '$prefix' was my own standard '/opt/cross' and > the '$sys-root' the > '/opt/host-$target' I tried finding a configuration within various arches toolchains. I couldn't find anything. Where did you find this? Also wondered, if by any chance you have spare cycles to try out building from our spksrc framework that would be really really nice of you. I've committed my current testing & mostly failures with gcc here https://github.com/SynoCommunity/spksrc/pull/5225/commits/39bff938665601f96e060b229c28e88e6aedcd44 The howto use is relatively straight-forward and documented https://github.com/SynoCommunity/spksrc using docker or lxc/lxd. Then its a matter of doing a make setup from the framework root directory and cd cross/gcc then make arch-x64-7.1 (e.g. make arch-<ARCH>-<DSM-VERSION>) or simply make all-supported (currently no archs are defined as unsupported for gcc as none is working anyway). Additional help or guidance would be much appreciated, thnx! Thnx in advance :) - vin 1,1 Top
