# Install
```
 pip install Pyllab
```

or


# Build .whl package On Linux:
```
pip install -r requirements.txt
sh generate_wheel_unix.sh
```

- On Linux specifically you have to fix the wheel package:

```
sudo docker run -i -t -v `pwd`:/io quay.io/pypa/manylinux1_x86_64 /bin/bash
```

go in /io and move the libllab.so to /usr/local/lib/

```
cd io
mv libllab.so /usr/local/lib/
```

Then repair the wheel package it.

```
cd dist
auditwheel repair package.whl --plat manylinux2014_x86_64
```

in the wheelhouse directory you have the fixed wheel package

# Build .whl package on MacOS
```
pip install -r requirements.txt
sh generate_wheel_unix.sh
sh repair_wheel_macos.sh
```

# Build .whl package on Windows

- It is a PIA. Why?

Pyllab is a cython library compiling .C files that use posix calls system. Now you can see the problem here. Just follow me in this journey:


- Install Mingw with MYSYS2: https://www.msys2.org/ follow the steps and also the passages to install mingw-w64 

-  now navigate to Pyllab with MYSYS2 and create the .lib library:

```
sh create_library.sh
```

- Go to your Python Folder (We assume as example we are using python 3.7):

- You can find your python folder with:

```
import sys

locate_python = sys.exec_prefix
print(locate_python)
```

- Create the file Python37\Lib\distutils\distutils.cfg that should look like this:

```
[build]
compiler=mingw32

[build_ext]
compiler=mingw32
```

- Download this .dll file https://it.dllfile.net/microsoft/vcruntime140-dll:

- Move it to Python37\libs and to Python37\DLLs

- Move libllab.lib previously built to Python37\libs

- Now, Move to Python37\Lib\distutils\cygwinccompiler.py and modify the function get_msvcr() as follows: https://bugs.python.org/file40608/patch.diff

- The last part

```
elif msc_ver == '1900':
```

change it to 

```
elif msc_ver == '1916':
```

- Now other bug fix: go to Python37\include\pyconfig.h and add these lines:

 ```
 /* Compiler specific defines */


#ifdef __MINGW32__
#ifdef _WIN64
#define MS_WIN64
#endif
#endif
```

- Now you can run from MYSYS2:

```
sh build_python_library.sh
```

 - https://bugs.python.org/file40608/patch.diff (function fix, changing from 1900 to 1916 was my guess and it worked, it enables the use of the .dll previously installed)

# Install .whl files

Once you have created the .whl file, you can install it locally using pip:

```
pip install package.whl
```
# Import the library in python

```
import pyllab
```
