     19By default both libgdal.a and libgdal.dll are generated. However, command line utilities such as gdalinfo.exe, etc... will statically link against libgdal.a, instead of libgdal.dll, which leak to huge binary files. You can edit GNUmakefile as such to avoid producing libgdal.a :

    133187If you use the regular Python Windows binaries, you need to edit $PYTHON_ROOT\lib\distutils\ccompiler.py (at least true for Python 2.7) and change the "_default_compilers" mapping as following, in order GCC to be used instead of MSVC when building the GDAL Python bindings :
