First we determine the filename template (self.filename_tpl), then we |

set the output filename (self.filename). |
|
|
|
The template is needed while creating aliases (self.get_aliases), |
|
which are needed while generating .so shared libraries for Linux. |
|
|
|
Besides this, there's also the import library name, which is only used |
|
on Windows since on that platform the linker uses a separate library |
|
called the "import library" during linking instead of the shared |
|
library (DLL). The toolchain will output an import library in one of |
|
two formats: GCC or Visual Studio. |
|
|
|
When we're building with Visual Studio, the import library that will be |
|
generated by the toolchain is self.vs_import_filename, and with |
|
MinGW/GCC, it's self.gcc_import_filename. self.import_filename will |
|
always contain the import library name this target will generate. |
