Build log
It seems to be connected to configuration item CONFIG_GCC_PLUGIN_LATENT_ENTROPY, which switches the undefined variable. |
When compiling the sys-kernel/gentoo-kernel-6.12.16 on a hardened system, the compilation always fail with the same error. On a non-hardened system, the kernel compiles and runs fine. Reproducible: Always Steps to Reproduce: 1. emerge -v =sys-kernel/gentoo-kernel-6.12.16 Actual Results: The compilation fails with the error in the attached log. Expected Results: The kernel would have compiled correctly.
