Mac OS X installation: [ERROR] The compilation of ctypes failed at "make".

[laowantong]

I have just installed a binary of OPAM with the official script on Mac OS X Yosemite 10.10.5, XCode 7.2.1. Now, trying to install iocaml works fine until make fails on ctypes. Various errors follow. Relaunching the installation produces the following:

MacBook-Air:~ username$ opam install iocaml

Seems to be installing a very, very old version of ctypes. Perhaps try ``` $ opam install ctypes.0.11.2 iocaml ```

It's a little surprising that the depext command isn't finding anything. Do you have Homebrew or MacPorts installed?

[laowantong]

@yallop Not at all.

@andrewray Thanks, unfortunately that still fails:

[andrewray]

@yallop is correct - you need `libffi` installed in order to find `ffi.h` and that you might, therefore, require something like homebrew. To fix the new problem here with iocamljs-kernel, you will need to constrain it manually, for now I think this should work ``` opam install js_of_ocaml.2.8.3 iocaml ``` Let me know how it goes, as it is something I should fix in the opam repo.

Don't know why it is looking for a user named sabae. For Julia, I remember having installed it a long time ago. Anyway, this is just a warning, may be unrelated to the fatal error.

Concerning:

opam install js_of_ocaml.2.8.3 iocaml

it fails too, but I guess it's normal since libffi is still missing.

[laowantong]

Actually it seems that I already have libffi in several places (I just kept 3 in the following):

$ locate libffi
/Applications/Dropbox.app/Contents/Frameworks/libffi.6.dylib
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib/libffi.tbd
/usr/lib/libffi.dylib

[andrewray]

Can you see ffi.h? On my (linux) system I need a package called libffi-dev to get the header files.

[laowantong]

Yes, in two places:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/ffi/ffi.h
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift-migrator/sdk/MacOSX.sdk/usr/include/ffi/ffi.h

[yallop]

@laowantong, you may be able to fix this by setting the LIBFFI_CFLAGS and LIBFFI_LIBS environment variables when installing ctypes. More details here: https://github.com/ocamllabs/ocaml-ctypes/blob/e66d23ea56fad3ef7c6b2c6955bebb06b01cb2d2/Makefile#L200-L209

That said, the recommended approach is to install libffi via MacPorts or Homebrew, if possible. The system-installed libffi is often so old that it lacks features required by ctypes.

[laowantong]

@yallop Thanks. Since all of this is far above my head, I am not quite sure which replacement is required, tentatively:

export LIBFFI_CFLAGS=-I//Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/ffi/include
export LIBFFI_LIBS=\"-L//Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/ffi/lib -lffi\"

But the latter is rejected with the following message:

-bash: export: `-lffi': not a valid identifier

Sorry for having taken too much of your time, but I think I am going to give up here. I have tried the recommended approach (with homebrew) last year, with no more success, going deeper and deeper into the rabbit hole with no result at the end of the day.

[yallop]

The double quotes (in the LIBFFI_LIBS) shouldn't be preceded by \:

export LIBFFI_CFLAGS=-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/ffi/include
export LIBFFI_LIBS="-L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/ffi/lib -lffi"

[laowantong]

OK, this one was really stupid, sorry. After the correction, installing ctypes fails later:

### stderr ###
# /Users/username/.opam/4.02.1/build/ctypes.0.11.2/src/ctypes-foreign-base/ffi_call_stubs.c:22:10: fatal error: 'ffi.h' file not found
# #include <ffi.h>
#          ^
# 1 error generated.
# make: *** [_build/src/ctypes-foreign-base/ffi_call_stubs.o] Error 2

[yallop]

That looks like progress. Does the following help things along any further?

export LIBFFI_CFLAGS=-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/ffi/
export LIBFFI_LIBS="-L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib -lffi"

(The directories in the above should be the respective locations of the header file (ffi.h) and the shared library.)

[laowantong]

Yes, this goes further.

Not sure what to do next:

opam install js_of_ocaml.2.8.3 iocaml

... gives some new errors I think:

[ERROR] The compilation of iocamljs-kernel failed at "make clean min".
[ERROR] The compilation of iocaml-kernel failed at "make all".
...
### stderr ###
# iocaml_zmq_stubs.c:1:10: fatal error: 'zmq.h' file not found
# #include <zmq.h>
#          ^
# 1 error generated.
# make: *** [stub] Error 2

Same thing with the original command:

opam install iocaml

And this time, zmq.h is nowhere to be found.

[andrewray]

The iocamljs-kernel failure I will have a look into and try to find some set of working package versions.

For iocaml, just like libffi, you will need a development version of zmq3 or 4 installed.
