Ask away: http://ask.fedoraproject.org Unfortunately nothing worked. In the cuda distribution there is a host_config.h file which contains the following lines: #if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ > 9) #error -- unsupported GNU version! gcc versions later than 4.9 are not supported! #endif /* __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ > 9) */ This checks the version of the compiler and triggers an error with gcc-6.1 even if I pass --std=gnu89 which was the default C standard in gcc-4.9. Second, the gcc-4.9.src.rpm did not build with gcc-6.1. Initially it did not build because it required /lib/libc.so.6 and /usr/lib/libc.so.6 (in addition to the lib64 versions), so I just removed /lib/libc.so.6 and /usr/lib/libc.so.6 from the gcc.spec file. The rebuild process did start after that, and I thought it would go through, but it bombed out with some compilation error which I don't feel inclined to fix, as it must be due to some incompatibility between my gcc-6.1 and what I'm trying to compile. I might get it to compile if I can specify gcc --std=gnu89 when compiling the old compiler, but I don't know how to pass compiler options to rpmbuild. Third, I was only able to find a Fedora-21-Live image and I created a virtual box from it, booted that up and installed to disk. But, as one might expect, gnome-boxes only knew about the Live VM, and each time I would boot it up, it would boot up the live image, not the one I installed to disk. Not sure how install to disk works in a VM. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://lists.fedoraproject.org/admin/lists/users@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
