Then it'd most likely be the issue discussed in <https://gcc.gnu.org/PR83790> "Update nvptx target to work with cuda 9". By now, there has a fix been committed to GCC trunk, and I assume the same would also work on earlier GCC releases/branches. > I was able to build that part for gcc-7.2.0 with the same commands. Interesting. Or, maybe you've not been using CUDA 9 in that build? Grüße Thomas
