Compilation error: cannot initialize a parameter of type 'int32_t *'

[cveaux]

Hi, I've being trying to install pyreaper, first with pip install pyreaper and then by cloning the repository and doing:
git submodule update --init --recursive
python setup.py build (I also tried python setup.py develop)

however in each case I got this error:

pyreaper/creaper.cpp:4153:155: error: cannot initialize a parameter of type 'int32_t *' (aka 'int *') with an rvalue of type '__pyx_t_5numpy_int32_t *' (aka 'long *')

it was preceded by this warning (although I think it's independent from the error message).
warning: "Using deprecated NumPy API, disable it by " "#defining NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION" [-W#warnings]

Have you encountered this error before ?

I forgot to say that my version of Cython is 0.27.3

and the corresponding code in creaper.pyx:

/* "pyreaper/creaper.pyx":184

•     = np.zeros(pN, dtype=np.float32)
  

• et.GetTrackTimes(pm_track.ptr, & pm_times[0])
  

• et.GetTrackVoicedFlags(pm_track.ptr, & pm[0])             # <<<<<<<<<<<<<<

I haven't encountered it ever. What platform are you on? Windows perhaps?

[cveaux]

No I'm on OSX 10.13.3

[r9y9]

I'm on OSX 10.13.3 too. Could you provide me more detailed information? python version, conda/virtualenv, gcc (clang) version, etc.

[cveaux]

I'm using Python 2.7.10 (in a virtual environment)

clang --version:
Apple LLVM version 9.0.0 (clang-900.0.39.2)
Target: x86_64-apple-darwin17.4.0

and this is the flags used for the compilation:

cc -fno-strict-aliasing -fno-common -dynamic -arch x86_64 -arch i386 -g -Os -pipe -fno-common -fno-strict-aliasing -fwrapv -DENABLE_DTRACE -DMACOSX -DNDEBUG -Wall -Wstrict-prototypes -Wshorten-64-to-32 -DNDEBUG -g -fwrapv -Os -Wall -Wstrict-prototypes -DENABLE_DTRACE -I/opt/X11/include -arch i386 -arch x86_64 -pipe -I/Users/cveaux/Projects/Deepzen/work/venv/lib/python2.7/site-packages/numpy/core/include -I/Users/cveaux/Projects/Deepzen/work/repos-3rd/pyreaper/lib/REAPER -I/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c pyreaper/creaper.cpp -o build/temp.macosx-10.13-intel-2.7/pyreaper/creaper.o

[r9y9]

Okay, I think -arch i386 does cause the compile error. I didn't pay attention to 32-bit architectures.. Can you try the following command?

ARCHFLAGS="-arch x86_64" pip install pyreaper --no-cache-dir -v

[cveaux]

Great, it compiles and install fine with the ARCHFLAGS.
Thanks!

[r9y9]

Nice! I will leave the issue open until I find more general fix.

on windows 10, 64-bit architecture, I have the same problem but cannot use the provided solution: simply no ARCHFLAGS option on windows to run pip. Doesn't work either to add this parameter as environment variable.
I am currently unable to install pyreaper in any form into my machine. BTW it works on Ubuntu 64-bit.
Please fix this because is quite a sensitive issue being limited to specific OS and/or architecture.

[r9y9]

Sorry for the inconvenience, but it's hard to fix for me since I don't have windows machines...

[r9y9]

Seems like env command exists on windows? env ARCHFLAGS="-arch x86_64" pip install pyreaper --no-cache-dir -v ?
