Some linker problem. I was guessing Intel is using clang for their compiles.

namcap also complains about missing dependency openssl.

@bsdice: what error did you see from GCC?

Package did not compile for me. Another day another gcc problem. So I switched to clang.

@lahwaacz: simdjson isn't in official repos, and is only required by pcm. By switching to the bundled version, one can now use extra-x86_64-build to produce the package in one go, without the need to build simdjson first. I would also very much like to use a packaged simdjson if it is in the official repo.

Also, simdjson is introduced as a git submodule and its version is decided by the pcm repo. It isn't simply an untagged master branch.

What's wrong with building with system simdjson package? Bundling the dependency is not right, especially when the PKGBUILD references untagged sources from the master branch...

I can't build the project:
