Revery: undefined reference to `FT_Init_FreeType' on Mac

[SeraphRoy]

Run esy build on my Mac and I get the following error:

    # esy-build-package: running: './esy/test.sh'

FreeType 2.9.1 is already installed by brew install freetype.

My Mac version: 10.14.2

Any help?

[OhadRau]

Hmm. did you esy install already? Looks like there's some esy packages missing.

[SeraphRoy]

@OhadRau Yeah esy install is fine but but esy build.

[MusiKid]

Is it normal that it uses the mingw32 compiler?
The problem may come from there.

/usr/local/bin/x86_64-w64-mingw32-gcc
Using compiler: x86_64-w64-mingw32-gcc

[SeraphRoy]

@Musikid That could be.. How do I configure the compiler when using esy build?

[SeraphRoy]

Ok so @MusiKid you are right that x86_64-w64-mingw32-gcc is the issue with esy-freetype. In esy-freetype package ./esy/test.sh I see the following:

  1 if which x86_64-w64-mingw32-gcc; then
  2    ¦CC=x86_64-w64-mingw32-gcc
  3    ¦CCLIB=
  4 else
  5    ¦CC=gcc
  6    ¦CCLIB="-lbz2 -lpng -lz"
  7 fi

Somehow my Mac does have x86_64-w64-mingw32-gcc installed so it uses that which it shouldn't be. So I think this is a bug in esy-freetype, whose maintainer is also @bryphe is that correct?

And unfortunately after bypassing the esy-freetype issue by temporally removing my x86_64-w64-mingw32-gcc, I got another error saying:

The error is too long to paste here. reason-glfw is also a package of @bryphe . Could you provide some more information as the main package maintainer whether I did something wrong or this is indeed an issue with your package(s)? Thanks!

[bryphe]

Thanks for all the help troubleshooting! @jaredly helped me on the Discord too (had the same issue).

Indeed, @MusiKid and @SeraphRoy those checks are wrong - nice find - they're assuming only Windows has the x86_64-w64-mingw32-gcc, but turns out its pretty common to have that cross-compiler on OSX too.

I fixed those issues in freetype2 and harfbuzz, and pulled those fixes in Revery w/ #266 , which is in the latest master.

Could you please try pulling the latest and letting me know how it goes? Curious to see if those GLFW errors still reproduce.

[SeraphRoy]

Hi @bryphe thank you for your reply! After pulling the lastest master and build, the esy-freetype issue goes away but not GLFW. The error looks to me the same/similar but paste an excerpt here just in case:

Also attached the .log (renamed to .txt as github doesn't allow me to upload with that suffix) and .info files in case you need them:

esy_glfw-3.2.1008-c9039271.log

esy_glfw-3.2.1008-c9039271.txt

Please ask if you need anything else. Thanks for the help!

[SeraphRoy]

Sorry the above means renaming .info to .txt but keeping .log the same.

[bryphe]

Thanks @SeraphRoy for the logs, very helpful! I fixed esy-glfw to have a more robust check for Windows and am picking that up in #273 . Hopefully that's the last of these issues... 🤞

[bryphe]

Merged #273 - please try latest master and let me know how it goes.

[SeraphRoy]

Great the latest master works! Thank you so much for the help!

[bryphe]

Wonderful - thanks for confirming @SeraphRoy!
