The above is wrong. The kernel (and modules) record what version of GCC they were compiled with. This version is checked at module load. If the kernel's GCC version doesn't match the modules GCC version, the module loading fails. This only becomes an issue with modules that are compiled outside of the kernel tree [1]. To fix this you have two options. either switch out which version of gcc you are using and recompile modules that are maintained outside of the tree, or recompile your kernel with the current version of gcc. First though, you need info: # modinfo <modname> | grep vermagic # cat /proc/version # gcc-config -l I would recommend recompiling the kernel, but it's up to you. hth, Jason [1] - The caveat being when the GCC version has changed after the kernel tree was already compiled and installed, and you are recompiling the kernel tree for one module, without cleaning the tree. -- gentoo-amd64@gentoo.org mailing list
