Description Agostino Sarubbo gentoo-dev

2022-11-29 12:34:46 UTC

https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/

Issue: dev-lang/gnat-gpl-2021-r4 installs less files with clang stricter.
Discovered on: amd64 (internal ref: clang-stricter_tinderbox)

NOTE:
To reproduce this issue:
1) Install the package with CC=clang - CXX=clang++
2) Put the list of the installed files into a file ( qlist -e PACKAGE:SLOT | sort | uniq > /tmp/qlist1 )
3) Install the package with CC=clang - CXX=clang++ - CFLAGS/CXXFLAGS=-Werror=implicit-function-declaration -Werror=implicit-int -Werror=incompatible-function-pointer-types
4) Put the list of the installed files into a file ( qlist -e PACKAGE:SLOT | sort | uniq > /tmp/qlist2 )
5) See the diff between the two files ( diff -ru /tmp/qlist_1 /tmp/qlist_2 )

On this machine:
- the installed files with clang are 4111
- the installed files with clang stricter are 4079

This type of report comes from a check that is a bit outside of the tinderbox, that's the reason because build.log was not provided (however in cases like these the build.log doesn't help much) but if you need further help to diagnose this issue feel free to ask.

In any case I'm providing a diff.

this package does not support building with clang/clang++.
It is gcc (adapted from adacore) and build only with gcc

It is probably ignoring CC and CXX as the use flag bootstrap is not disabled.

I understand, bbut if clang does not work here, let's hang the build process, see:
