fatal error: 'mbedtls/arc4.h' file not found

[euclaise]

When running the installer I get:

[ 54%] Building C object plugins/obs-outputs/CMakeFiles/obs-outputs.dir/librtmp/rtmp.c.o

Indeed, /opt/homebrew/include/mbedtls does not include an arc4.h, including only the following:

Try the following:

1. Uninstall the latest version and rollback the older version 2 of mbedtls

   brew remove mbedtls
   brew install mbedtls@2

2. Edit the install.sh and change the mbedtls to use mbedtls@2, this to avoid the reinstall of the new version.

3. Compile with REPACKAGE=true ./install.sh

4. ???

5. Profit!

@cicloid thanks, I can confirm that your solution works!

[ThomasWaldmann]

The remaining questions is for what they need crypto as crappy as arc4. :-)

[tobiasbischoff]

Ran into the same issue, maybe someone should change install.sh to ask for mbedtls@2 in the first place.

[jbubik]

@carlosonunez please commit #13. Currently mbedtls points to mbedtls@3 (incompatible changes in mbedtls API since 2.27.0)

I had the same mbedtls issue and after the ...@2 fix, it proceeds but now I get a new error with jansson.h. Unclear what to do now. (This is on MacOS 12.0 Beta (21A5304g))

Hello! I just did a fresh rebuild of OBS 27.0.1 and, unfortunately, wasn't able to replicate this issue. However, since I did merge the PR that fixes this, I'm going to close this issue. Feel free to re-open it if this continues to be a problem.
