I see no error here...

I included an incomplete set sorry.

It always breaks shortly after this warning:

Hi, sorry for writing in old bug but this is still a valid case.

Trying to build Calf 0.9.3 on OpenMandriva Cooker with LLVM/Clang 11 and I see same error:

Worth to add, If I switch compiler to GCC, then all is compiled fine.
and here is also bug on Gentoo https://bugs.gentoo.org/740158

[yurivict]

Any solution to this?

[yurivict]

Any hope to fix build with clang? The FreeBSD Calf port is broken because of this.

[vimproved]

Digging deeper here, this issue seems to be caused by the -export-symbols-regex "lv2_descriptor" in libcalf_la_LDFLAGS. Removing it makes calf link completely fine with LLD.

[vimproved]

Removing this doesn't seem to cause any issues but I'd like to defer to someone who knows more about why this was added in the first place.

[vimproved]

Specifically, this seems to stem from LLD handling -retain-symbols-file differently from GNU ld. GNU ld doesn't discard any symbols when using -retain-symbols-file, however LLD does.

[vimproved]

Removing the export-symbols-regex shouldn't break anything since libtool exports all symbols by default.

[yurivict]

The FreeBSD had this problem, and it has -module removed from the link lines, likely for the same reason.

Odd. That doesn't fix it for me on Linux.

[yurivict]

Here are all the patches from the FreeBSD port: https://cgit.freebsd.org/ports/tree/audio/calf-lv2/files

Maybe if you would apply all of them this would help.

It was a long time ago that I solved this problem on FreeBSD, and I unfortunately don't remember the details now.

Nevermind, it seems like the FreeBSD fix does the same thing as my PR of removing -export-symbols-regex. It does compile with all the FreeBSD patches applied.
