Bug 855458 – net-misc/dahdi-3.1.0-r4 calls cc directly

• Product: Gentoo Linux
• Status: UNCONFIRMED ---

Issue: net-misc/dahdi-3.1.0-r4 calls cc directly.
Discovered on: amd64 (internal ref: ci)

NOTE:
As per QA policy, toolchain tools must not be called directly because they can cause issue in cross-compiling and because is not possible use a different CC implementation (like clang). To reproduce, please use sys-devel/gcc-config[-native-symlinks], sys-devel/binutils-config[-native-symlinks].

Error(s) that match a know pattern:


/bin/sh: line 1: gcc: command not found

I'm unable reproduce this one, even after rm /usr/bin/{gcc,ld} I still get a successful build and merge.

Going to need help on this one.

did you build sys-devel/gcc-config with -native-symlinks ?

[Comment 5 Jaco Kroon 2022-07-04 12:12:45 UTC]

Doesn't look like something I can do:

# USE=-native-symlinks emerge -pv gcc-config

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] sys-devel/gcc-config-2.5-r1::gentoo  USE="(cc-wrappers) (native-symlinks)" 0 KiB

Total: 1 package (1 reinstall), Size of downloads: 0 KiB

I did however do rm /usr/bin/{gcc,ld} directly prior to emerge -1av dahdi - after which:

plastiekpoot [14:11:55] ~ # which ld gcc
which: no ld in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/usr/lib/llvm/14/bin:/usr/lib/llvm/13/bin)
which: no gcc in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/usr/lib/llvm/14/bin:/usr/lib/llvm/13/bin)

So I trust that any invocation of gcc should be caught.  If that's not good enough, please advise on how to disable native-symlinks fully.

Gives you an idea what you need to do. Study it if you want to try on your own system, but you can simply run it in a testing environment.
