Something strange happened a while back - although
GCC builds
were
and the repository transaction was working, the actual compilers weren’t showing up on the repository.There just wasn’t any
gcc
binary in the usual places.
Now, this is very wierd, because functional tests are run on the compilers before they are shipped - so my suspicion was aroused. The initial investigation pointed to something going wrong in the delivery part rather than the integration part.
Even after re-shipping the build artefacts, this was the case - I triggered the
shipit
job, to synchronise the
gcc
artefacts in the repo, then waited for the transaction complete. –
On my laptop :

No gcc !? 🤔
Turns out this was due to a previous hack which we had to include in the repository transaction step of the pipeline, which removed hard links . Previous versions of the CVMFS server could not handle hard links (at least this was the case when FR3 was built).
Guess what : the GCC binaries are hardlinked into
$GCC_DIR/bin
from various places - so these were getting removed in the course of the repository transaction !
This has now been fixed :

Time to build us some netcdf !
