ci has reproduced this issue with version 3.13.3 - Updating summary.

[Comment 3 Sebastian Parborg 2022-02-18 11:25:19 UTC]

This is the offending cmake lines:
---
execute_process(COMMAND objdump -C -t ${file} OUTPUT_VARIABLE output)
string(REPLACE "\n" ";" output ${output})
---

I don't have any issues building this on my machine. So I have no clue why this would fail on your automated test system.

Do you have any ideas?

ci has reproduced this issue with version 3.13.4 - Updating summary.

binutils-config[-native-symlinks], I'm guessing.

[Comment 6 Sebastian Parborg 2022-08-11 11:09:45 UTC]

That does seem likely.

Should I add that as a required use flag?

Or is there an easy way in cmake to query for the path to the active binutils `objdump`?

[Comment 7 Violet Purcell 2023-07-09 13:16:05 UTC]

I'm also hitting this issue with llvm-objdump. This may be unrelated though. Manually running "objdump -C -t /var/tmp/portage/media-libs/embree-3.13.5/work/embree-3.13.5_build/libembree_avx512.a" produces no output.

[Comment 8 Violet Purcell 2023-07-09 13:26:49 UTC]

Oddly, I can't reproduce this when building outside of portage.

[Comment 9 Violet Purcell 2023-07-09 13:32:51 UTC]

Okay, it seems like by default embree builds with -g in CXXFLAGS. For some reason, this isn't the case when building with portage. The cmake step it fails on requires the static archive it runs on to have debug info for objdump to produce any output.

Nevermind, that's not it.

[Comment 11 Violet Purcell 2023-07-09 13:48:44 UTC]

I'll open a new bug for the issue with LLVM binutils, since it seems to be unrelated to the original build failure.

ci has reproduced this issue with version 4.3.0 - Updating summary.
