Hi everyone,
I’m trying to install Gentoo musl-llvm on an AMD64-based laptop, using the newest release of Gentoo LiveGUI. Since I did most of steps of AMD64 handbook last week, the stage 3 file extracted on disk is stage3-amd64-musl-llvm-20250330T165244Z.tar.xz.I’m currently stuck at manual configuration of the Linux kernel. While trying to run | Code: | | make localmodconfig |
in /usr/src/linux, I get the following output:
| Code: | HOSTCC scripts/basic/fixdep
/bin/sh: line 1: gcc: command not found
make[2]: *** [scripts/Makefile.host:116: scripts/basic/fixdep] Error 127
make[1]: *** [/usr/src/linux-6.12.21-gentoo/Makefile:623: scripts_basic] Error 2
make: *** [Makefile:224: __sub-make] Error 2 |
The second line surprised me, since I thought that emerging sys-kernel/gentoo-sources should automatically take care of dependencies and/or fetch the right files. The handbook did so far include notes regarding musl users, but nothing here this time. What’s the correct way of fixing this problem? I tried searching for solutions, but found nothing similar enough to my case.
I’m aware of various nuances of using a musl-based OS, I deliberately decided on choosing this flavor. While I don’t consider myself an advanced Linux user, I’m neither entirely new to it. I even installed Gentoo once (and it worked), but that was years ago and many things have changed since then.
If it’s anything of importance, I also got weird behavior from sys-kernel/modprobed-db. When I tried to run inside the chroot, it gave me:
| Code: | | ==> ERROR: Cannot locate user home directory. |
I checked and /root is there. But when I opened another terminal window in the LiveGUI and (without chrooting) pointed to the binary on the laptop’s disk, it ran as described in the handbook, as well as the Wiki page. I ended up manually copying the created database onto the laptop. |

I believe you need LLVM=1 added to all kernel make operations. Otherwise, the kernel build assumes gcc.
