ocamlfind -toolchain windows ocamlc -I /freetype2 src/ftintf.c
Here's the problem:
-I /freetype2

Hang on. Why are you expecting camlimages-windows to pick up anything installed via Homebrew? That's not how cross-compilation works; nothing installed in the host environment is relevant.

from opam-cross-windows.

Good point! That should be coming from MXE. All the other packages we use seem to be picking up MXE, except this.

from opam-cross-windows.

So... these two commands fail: https://github.com/whitequark/opam-cross-windows/blob/master/packages/conf-gcc-windows.1/opam#L6-L7

Could you try running them manually? I can set up MXE on my OS X VM but it'll take a while.

from opam-cross-windows.

Of course, replace %{conf-gcc-windows64:prefix}% with the prefix leading to your gcc inside MXE.

Coming back to this, I think the issue is that freetype is being installed in a freetype2 sub-directory of the include. Adding the symbolic links below makes it work. Is there a better fix?

sakhalin% pwd
/Users/mhayden/plotter/proj/mxe/mxe/usr/x86_64-w64-mingw32.shared/include
sakhalin% ln -s freetype2/
freetype/ ft2build.h
sakhalin% ln -s freetype2/freetype .
sakhalin% ln -s freetype2/ft2build.h .

from opam-cross-windows.

Hm, this freetype idiosyncrasy is supposed to be handled here: https://github.com/whitequark/opam-cross-windows/blob/master/packages/camlimages-windows.4.2.1/opam#L88-L90

from opam-cross-windows.

Specifically, "-I" "%{conf-gcc-windows:c-include}%/freetype2" fails as you get a -I /freetype2 flag, which means that the variable conf-gcc-windows:c-include is empty. This is set here: https://github.com/whitequark/opam-cross-windows/blob/master/packages/conf-gcc-windows.1/opam#L4-L7. Something on OS X is behaving funky, probably because I have an implicit GNU assumption somewhere in that horrible script.

Oh.

user@users-iMac:~$ readlink -f x
readlink: illegal option -- f

There's... no good way to make everything work without readlink -f. There are no good solutions to that either (see https://stackoverflow.com/questions/1055671/how-can-i-get-the-behavior-of-gnus-readlink-f-on-a-mac). Please install GNU readlink and make sure it's in PATH as readlink.

Hi Peter,

I installed coreutils from Homebrew and linked /opt/local/gin/greadlink to ~/bin/link. It still won’t install camlimages-windows. Am I doing something wrong?

Yeah--as I understand the symlink is named greadlink, it should be readlink. I'll look into making the opam build script look for greadlink on OS X later, but such conditions are irritating to implement due to some of opam's design choices.

I named the symlink readlink but things still didn’t work. If readlink is required, maybe the install should fail if it is missing or doesn’t support ‘-f’ option?

Sorry--I neglected to mention. After installing readlink you need to reinstall conf-gcc-windows. That should fix it.

Ok; that worked. Thanks! —M
