Building with gcc-15 fails #814
Comments
|
Builds fine with gcc-15 for me ( 570.124.04 and last update 570.133.07). ~$ gcc --version
|
|
I'm using the development version of Fedora (rawhide), which started using gcc-15 in early January. |
|
Fedora 42, not building neither 570 nor 575. |
Maybe report the issue to the rpmfusion maintainers to apply the patches. |
This is when trying the .run file or compiling it by hand, not using the rpmfusion packages. |
|
Rpmfusion added a patch (nvidia-kernel-ccflags-y.patch) for the latest 575.51.02 and fc43 rawhide ; but there is no build yet for fc42. |
|
I can confirm that using https://github.com/negativo17/nvidia-kmod/blob/fedora-42/nvidia-kernel-ccflags-y.patch allows for compile with gcc-15 and linux-6.14.1 |

Build Command
Build using gcc-14.2 completes.
Build with gcc-15.x fails with errors that were warnings in previous gcc.
Workaround is to add the following no-error statements, until the code is updated to avoid these warnings.
EXTRA_CFLAGS += -Wno-error=return-type -Wno-implicit-function-declaration -Wno-int-conversion -Wno-incompatible-pointer-typesTerminal output/Build Log
As above
Also errors
