Marcus,
I think I have found the issue, just not a correct solution yet. Based
on the bug report:
https://cmake.org/Bug/print_bug_page.php?bug_id=14367
Which is marked as not a bug, but explains the issue I am seeing very
well.
gnuradio-runtime.swig/CMakeLists.txt uses an absolute path for the
DESTINATION ( or something that gets turned into an absolute path) in the
lines:
install(
TARGETS runtime_swig
EXPORT runtime_swig-export
DESTINATION ${GR_PYTHON_DIR}/gnuradio/gr
)
The DESTINATION should point to a relative path, based on the above bug
report.
For testing I changed the last line to:
DESTINATION lib/python3.5/site-packages/gnuradio/gr
And rebuild gnuradio for cross-compiling.
I then build OOT modules gr-iio from my fork and gr-paint38, both
successful built. I have not tried executing the code yet.
I am not sure of the correct way to create a variable which will point to
the relative path only of GR_PYTHON_DIR within the CMake process, and I
think that is what is needed to correctly fix the issue. This may show up
because the installed path is /usr/lib/... on the sysroot and not an actual
PREFIX.
Thanks
Toby
