> - I did have a newer version of binutils already installed, so I prepended the ../bin and ../lib of this binutils to my PATH and LD_LIBRARY_PATH, respectively. Considering your remark that the old binutils doesn't support plugins, I think this is exactly what the warning I got earlier pointed to. > - I removed the --disable-multilib option from the nvptx GCC configuration step. > - I added the --enable-plugins to the host GCC configure options (I couldn't find this as a configure option though on https://gcc.gnu.org/install/configure.html, nor on the instructions in https://gcc.gnu.org/wiki/Offloading ?) > - I compiled my test program with the new gcc, making sure the new binutils ../bin and ../lib are still in my PATH and LD_LIBRARY_PATH, respectively. Ok, that might have been slightly unclear, just to clarify: I did step 1-3 (below), then recompiled GCC with my (adapted) compilation script. Then I did step 4.
