Running

pip3 install git+https://github.com/src-d/wmd-relax

I got this issue

Following Farama-Foundation/ViZDoom@1737ff0

That was solved by adding #include <iostream> in emd.h

 #include <cmath>
 #include <algorithm>
 #include <string>
+#include <iostream>

[melodywolk]

Then I had another issue with openmp
Running cmake -D CMAKE_BUILD_TYPE=Release .
I got this error message

CMake Error at /usr/local/Cellar/cmake/3.9.0/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:137 (message):

I managed to solve this so I thought it could be useful

1. brew install llvm

2. Following this https://stackoverflow.com/questions/46414660/macos-cmake-and-openmp I changed CMakeLists.txt (here is the diff)

     # workaround

And compile with CC=gcc-7 CXX=g++-7 cmake -DCMAKE_BUILD_TYPE=Release .

3. Using make -j I had this error message

wmd-relax/or-tools/src/base/sysinfo.cc:35:10: error: unused variable 'task' [-Werror=unused-variable]
   task_t task = MACH_PORT_NULL;
          ^~~~

make[1]: *** [CMakeFiles/wmdrelax.dir/all] Error 2
make: *** [all] Error 2

That I just solved by commenting this line

4. Finally everything worked great

make -j

But trying to import the library in python (3.6.4) caused an error

>>> import wmd
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "wmd-relax/wmd/__init__.py", line 11, in <module>
    import libwmdrelax
ModuleNotFoundError: No module named 'libwmdrelax'

That was solved following this https://github.com/src-d/kmcuda
and renaming the file
mv libwmdrelax.{dylib,so}

And it worked :)

And compile with CC=gcc-7 CXX=g++-7 cmake -DCMAKE_BUILD_TYPE=Release .

1. Using make -j I had this error message

wmd-relax/or-tools/src/base/sysinfo.cc:35:10: error: unused variable 'task' [-Werror=unused-variable]
   task_t task = MACH_PORT_NULL;
          ^~~~
cc1plus: all warnings being treated as errors

make[1]: *** [CMakeFiles/wmdrelax.dir/all] Error 2
make: *** [all] Error 2

That I just solved by commenting this line

1. Finally everything worked great

make -j

[100%] Linking CXX shared library libwmdrelax.dylib
[100%] Built target wmdrelax

But trying to import the library in python (3.6.4) caused an error

>>> import wmd
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "wmd-relax/wmd/__init__.py", line 11, in <module>
    import libwmdrelax
ModuleNotFoundError: No module named 'libwmdrelax'

That was solved following this https://github.com/src-d/kmcuda
and renaming the file
mv libwmdrelax.{dylib,so}

And it worked :)

Hi,

Thanks for your sharing.
Right now, I still have some questions.
I have same issue with you that I can not find the OpenMP,
so, I change the CMakeList.txt' just like your wrote, but it still has the error.
Then, I replace "gcc-7" to "Clang" and it works.

After that, I try to run make -j, I have the following problems:

(cvan2) cvans-MacBook-Air:wmd-relax cvanzy$ make -j

Do you have idea about that?

I think I have resolved this issue.
I download the gcc version 7 and implement in the code then works.

But when I run the code, it always shows:
Segmentation fault: 11
