brew doctor

Your system is ready to brew.

Verification

• My "brew doctor output" says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.

What were you trying to do (and why)?

Running some build automation checks whether libarchive is installed using pkg-config --exists libarchive, and fails because pkg-config returns 1 even when I have updated the PKG_CONFIG_PATH environment variable to point to the libarchive.pc file as described in brew info libarchive.

What happened (include all command output)?

pkg-config appears to be able to see the package when queried with --modversion, but it returns 1 (false) when asked if the package exists using the --exists option.

What did you expect to happen?

I expect pkg-config to return 0 when the package is installed and the .pc file is on the PKG_CONFIG_PATH.

Step-by-step reproduction instructions (by running brew commands)

brew install libarchive
echo ' export PKG_CONFIG_PATH="/opt/homebrew/opt/libarchive/lib/pkgconfig"' >> ~/.zshrc
source ~/.zshrc


pkg-config --modversion libarchive
# 3.6.2

pkg-config --exists libarchive; echo $?
# 1

I've tried this on two separate Macs, both running Ventura 13.1 (22C65).

What does pkg-config --exists --print-errors libarchive output? I'm betting it's the following:

Package iconv was not found in the pkg-config search path.
Perhaps you should add the directory containing `iconv.pc'
to the PKG_CONFIG_PATH environment variable
Package 'iconv', required by 'libarchive', not found

[graymalkin]

Ah, yes exactly that.

I think that makes this related to #117869. The work-around is good for me for now. Can I keep this issue open to track the bug?

The workaround from that issue (for those who need it and find this thread googling) is to remove Requires.private: iconv from /opt/homebrew/opt/libarchive/lib/pkgconfig/libarchive.pc. You might need to do chmod +w first.

It seems that this breaks building mpv from source (maybe also other formulas?).
