Notes:
|
|
- shared library support is buggy: it assumes that a static and dynamic library can be build from the same object files. This is not true on many platforms. For this reason it is only enabled on linux-gcc at the current time.
|
|
|
|
To add a platform:
|
|
- add its name in options allowed_values below
|
|
- add tool initialization for this platform. Search for "if platform == 'suncc'" as an example.
