To recompile a Cython module with the `-fPIC` flag, you can follow these steps:
1. Open your Cython source file (with the `.pyx` extension) in a text editor.
2. Add the following line at the top of your file to include the necessary Cython directives:
```python
# cython: language_level=3, boundscheck=False, wraparound=False, cdivision=True
```
3. Next, compile your Cython module using the following command:
```
cython --cplus -3 -f -w --fast-fail your_module.pyx
```
Here, `your_module.pyx` should be replaced with the name of your Cython source file.
The options used in this command are as follows:
- `--cplus`: Generate C++ code instead of C code.
- `-3`: Enable Python 3 syntax.
- `-f`: Include the `-fPIC` flag during compilation.
- `-w`: Disable all warning messages.
- `--fast-fail`: Abort compilation on the first error encountered.
4. After compilation, you can build the shared object file (`.so`) using a C++ compiler. For example, if you have `g++` installed, you can use the following command:
```
g++ -shared -pthread -fPIC -fwrapv -O2 -Wall -fno-strict-aliasing -I/usr/include/python3.8 -o your_module.so your_module.cpp
```
Make sure to replace `your_module.so` with the desired name for your shared object file.
Now you should have a recompiled Cython module with the `-fPIC` flag enabled.
