Convert the find
to a static list colon :
separated PKG_CONFIG_PATH list to reduce launch time.
Step 1. Run pkg-config --list-all
to determine what packages are already know by
pkg-config --list-all # tidy tidy - tidy - HTML syntax checker # tesseract tesseract - An OCR Engine # …
Step 2. Run find
to determine the pkgconfig
directories that contain *.pc files.
### long form `find` find /usr/local/Cellar -name 'pkgconfig' -type d | grep lib/pkgconfig | tr '\n' ':' | sed s/.$// find /usr/local/Cellar -name 'pkgconfig' -type d | grep share/pkgconfig | tr '\n' ':' | sed s/.$// # - or - find /usr/local/Cellar -name 'pkgconfig' -type d | grep pkgconfig | tr '\n' ':' | sed s/.$// ### short form `find` find / -name "pkgconfig" -print # /usr/local/Cellar/abc/0.1.5/lib/pkgconfig:…/usr/local/Cellar/xyz/2.6/lib/pkgconfig
Step 3. Add the paths libraries of interest, that are not already discoverable by pkg-config
, to PKG_CONFIG_PATH.
Option: use a /usr/local/Cellar/…
path which will need to be updated with each version number change.
export PKG_CONFIG_PATH=/usr/local/Cellar/abc/0.1.5/lib/pkgconfig export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/Cellar/abc/0.1.5/lib/pkgconfig export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/my/build/from/source/mmmm/0.1.5/lib/pkgconfig
Options: When the Cellar is linked (typically) into /usr/local/opt/…
then a version independent path can be found and used.
sudo find / -name "uvw" -print # /usr/local/Cellar/uvw # /usr/local/opt/uvw ls -l /usr/local/opt/uvw # /usr/local/opt/uvw@ -> ../Cellar/uvw/4.2_1
Set these:
export PKG_CONFIG_PATH=/usr/local/opt/uvw/share/pkgconfig export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/opt/xyz/lib/pkgconfig
Note: Apple ARM and Apple Intel have different homebrew Cellar
locations.
- Apple ARM:
/opt/homebrew/Cellar
- Apple Intel:
/usr/local/Cellar

I had a similar issue in Mac Mojave as /usr/include
is gone under Xcode 10, and you have to install a separate package to get it back.
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
