Dear Easybuilders, We would like to install a GCC with OpenMP 4.5 / OpenACC with offloading capabilities to nvptx targets as described here https://gcc.gnu.org/wiki/Offloading#How_to_try_offloading_enabled_GCC
We would of course prefer to do this installation with EasyBuild. As far as I can determine, no EasyConfigs are available for this yet, and I even doubt whether this can be build with the conventional GCC EasyBlock: the installation procedure for a GCC with offloading support is quite different, as nvptx-tool, nvptx-newlib, an accelerator GCC compiler and a host GCC compiler all need to be built (and it is suggested to install all in the same directory), through repeated configure/make/make installs (see e.g. this build script: https://gist.github.com/kristerw/4e9a735f2d755ffa73f9bf27edbf3c29 ). My questions to you: 1) Has anyone already tried building a GCC with offloading support though EasyBuild? 2) Specifically to the Gent people who wrote the GCC EasyBlock: would you think this can somehow be done with the current EasyBlock (my guess would be: no)? If not, would you think the existing EasyBlock should be adapted to support this, or would you feel a separate EasyBlock would be better? I personally wouldn't like 2 GCC EasyBlocks; on the other hand, incorporating it in the existing one results in a more complicated EasyBlock. I must immediately say that I am not yet sure if I can invest the time to write / adapt an EasyBlock for this, but I just want to explore my options and your thoughts on this.
