Cannot install gcld3 on OS X

[erip]

Hi all. I have protobuf 3.15.8 installed but when I try to install gcld3 through pip, protobuf headers aren't found when building from source:

Do you have any thoughts?

Ok

I just installed gcld3 successfully on macOS 10.14.6. First I installed protobuf through homebrew (brew install protobuf), then I installed gcld3 itself through pip (pip3 install gcld3).

It seems that you installed protobuf in a directory that's not part of gcc's default include directories (where gcc searches for header files such as above google/protobuf/stubs/common.h ). You can get gcc's default include directories by executing gcc -xc++ -E -v -.

You can add to gcc's default include directories by using the environment variables C_INCLUDE_PATH and CPLUS_INCLUDE_PATH. I haven't tried that myself, though.

Just a followup related to the previous comment, for those on macOS 12.1 and/or using M1 Silicon:

On M1 (ARM) Macs, after installing protobuf via Homebrew, the headers will be located in /opt/homebrew/include. So you'll need to add this path to CPLUS_INCLUDE_PATH or CPATH, depending on which compiler you're using.

For example, if using clang from the Xcode Command Line Tools, you would install via:

$ CPATH=/opt/homebrew/include pip3 install gcld3

[sschamp]

For me, this is what worked on an M1 Mac:

brew install protobuf
CPLUS_INCLUDE_PATH=/opt/homebrew/include LIBRARY_PATH=/opt/homebrew/Cellar/protobuf/21.12/lib pip3 install gcld3

Optionally:

brew install gcc llvm
