Same issues. Does anyone knows a resolve?

Having the same issue, can not build successfully

Also have this issue.

I replaced the affected lines in benchmark_module.h with

#ifndef BENCHMARK_MODULE
// define new benchmark type for benchmark module
extern PyTypeObject BenchmarkType;
// define new benchmark error type (will be used for notifying errors)
extern PyObject *BenchmarkError;
#else
// define new benchmark type for benchmark module
PyTypeObject BenchmarkType;
// define new benchmark error type (will be used for notifying errors)
PyObject *BenchmarkError;
#endif

to conditionally compile the types only for the right source file, and this particular problem went away.
However, I hit #239 and could not go further.

Edited: delete 'extern' in modifition of 'benchmark_module.c'.
Hey guys, I have just found the solution. Just as @dfaranha said, replace the affected lines(about 56 to 60) in benchmark_module.h with:

#ifndef BENCHMARK_MODULE
// define new benchmark type for benchmark module
extern PyTypeObject BenchmarkType;
// define new benchmark error type (will be used for notifying errors)
extern PyObject *BenchmarkError;
#else
// define new benchmark type for benchmark module
PyTypeObject BenchmarkType;
// define new benchmark error type (will be used for notifying errors)
PyObject *BenchmarkError;
#endif

But you should also modify the benchmark_module.c after include the head file:

#add after include
#ifndef BENCHMARK_MODULE
// define new benchmark type for benchmark module
PyTypeObject BenchmarkType;
// define new benchmark error type (will be used for notifying errors)
PyObject *BenchmarkError;
#endif

And you'll solve this.

@fremakvi can you pls submit a PR?

I hit #239 when I was trying to install charm in conda base environment in this way. But when I create a new environment for charm, I installed it successfully. I'm still confused about this error.
