"opam install lame" failing on MacOS #6

Open omarmn opened 1 year ago

omarmn commented 1 year ago

Trying to install liquidsoap on Mac as per instructions on the book. I am using opam to install it. All packages install fine expect lame. I am not a developer by trade, but I'm self taught and I do as much as I can. I am helping 2 community radios to automate their processes here using liquidsoap, and this is causing a major blocker for us. Any help would be much appreciated. I get the following error when installing lame using opam:

compiling c program:

 [...]

For some reason, the "include" line is not finding the lame.h. I have installed lame using "brew", I can see it installed and lame.h file is there under the include folder in the LAME brew folders.

I am a little bit out of my depths here, but I tried editing the discover.ml file and I added an absolute path to the lame.h file to the include line, but that didn't work. I tried to copy the lame.h to the same place as discover.ml file, no luck here. I also tried another Mac (which is fresh out of the box) that had exactly the same problem.

Thanks :)

Maybe you want to use 4.13.1 instead of 5.0.0? I was able to get this to install under Rosetta with a new Mac (M2) after some playing around with it. Here's what I did:

Good luck!

deanh commented 1 year ago

The downside is that all OCaml/opam work should be done in Rosetta for this user or the .opam directory may become a mess–I didn't try to figure out how to maintain a separate arm64 install. This is fine for me, but could be a problem if you want to do any additional OCaml work.

I'm not familiar with the toolchain so I can't explain all of the reasoning here, but I ran into the same issue using macports and was able to resolve so i'll add some ideas;

I successfully installed liquidsoap via opam on x86 macos with ocaml 5.1 using these extra steps

Awesome thanks both. The project is currently on pause, shifted focus on other tasks. Once I get back to it, will report back :)

Same problem here with MacOS on Apple M1 / Sonoma 14.2.1

I finally managed to install lame with this command

% CPATH=/opt/homebrew/include LIBRARY_PATH=/opt/homebrew/lib opam install lame

It was clearly written on the home page here : https://www.liquidsoap.info/doc-2.2.3/install.html :)

Hi, I've restarted the project and once I set the PATHS as per above it worked for me too. I was following the instructions in the PDF, which didn't have those steps there. Thanks for pointing out this web page.
