configure: add option for user to override checks for Python modules
|
|
|
|
The check for google.protobuf is inherently flawed for cross-compilation,
|
|
as it uses the host Python to check for target modules.
|
|
|
|
In this case, it is not possible to check for a Pyhon modules altogether,
|
|
and we need to rely on the user to properly tell us whether we do or do
|
|
not have google.protobuf.
|
|
|
|
This is done by adding am autoconf cache variable:
|
|
ac_cv_have_pymod_google_protobuf
|
|
|
|
which can be set to:
|
|
- yes : force the test to be true
|
|
- no : force the test to be false
|
|
- (empty) : let the test decide
|
|
|
|
This is then used in AX_PYTHON_MODULE to override the test.
|
|
|
|
Currently, only the google.protobuf Python module is checked for, but
|
|
the same could be done later on of other Python modules that may be
|
|
added in the future, of course.
|
|
|
|
Fixes configure-errors like:
|
|
http://autobuild.buildroot.net/results/e63/e634d5f0cee3967caffaa6e7ada8c0968e3eff63/build-end.log
|
|
|
|
Also fixes some under-quotation in the python module check.
