|

This script provides distutils-based deployment for KLayout's
|
||||
standalone Python modules.
|
||||
|
||||
The standalone libraries are basically extension modules.
|
||||
Build requirements are:
|
||||
* curl library
|
||||
* expat library
|
||||
|
||||
The main challenge is to map KLayout's shared object architecture.
|
||||
The structure consists of the Python extension libraries and a bunch
|
||||
of libraries providing the actual implementation part.
|
||||
The Python extension libraries reference the implementation libraries.
|
||||
The extension libraries are prefixed with an underscore.
|
||||
|
||||
For example:
|
||||
|
||||
tl (Python) -> _tl, _gsi
|
||||
|
||||
There is a specific issue with the building of the extension
|
||||
libraries: distutils only allows building of shared objects
|
||||
as extension libraries and does not provide a intrinsic feature
|
||||
for linking other libraries into the extension library.
|
||||
|
||||
Hence we need to add the dependencies through "extra_objects".
|
||||
|
||||
On Linux there is a specific issue: The shared objects produced
|
||||
for extension libraries are not matching the Linux name conventions.
|
||||
So we have to add them as .so link objects including the path.
|
||||
If we do so, the runtime loading will look them up by their path
|
||||
and won't find them. So we need to take away the path with
|
||||
"-Wl,-soname" on Linux (see Config.link_args).
