Description Kent Fredric (IRC: kent\n) gentoo-dev 2020-06-19 06:24:04 UTC
First, to replicate this, you must undo some silly things done by gcc:

> rm /usr/bin/c99 
> rm /usr/bin/c89

As these are wrapper scripts installed in gcc's post_inst which are *also* broken because internally, they just invoke "gcc", which doesn't exist ( bug #728722 )

And then, also, you must make sure you purge ccache shadows

> eselect compiler-shadow clean all

Otherwise, configure will see a c99 in PATH and go "Yep, we can use that", without ever testing it works, and later failing in compilation, such as:

> make[2]: Entering directory '/var/tmp/portage/media-video/vlc-3.0.11/work/vlc-3.0.11/src'
> Makefile:3707: warning: ignoring prerequisites on suffix rule definition
> Makefile:3711: warning: ignoring prerequisites on suffix rule definition
> rm -f -- "../include/vlc_about.h.tmp"
> rm -f -- fourcc_gen
> rm -f -- revision.tmp
> c99 -I. -o fourcc_gen misc/fourcc_gen.c
> if ! git \
>                 --git-dir="../.git/" describe \
>                 --tags --long --match '?.*.*' --always; then \
>         cat ./revision.txt ; \
> fi > revision.tmp
> ccache: error: Could not find compiler "c99" in PATH
> make[2]: *** [Makefile:3719: fourcc_gen] Error 1
> make[2]: *** Waiting for unfinished jobs....
> mkdir -p -- ../include

Or

_Only_ then can you see the proper failure in configure.
