[1] +We do not actually need this function at all, as we know the iio library +will be referencable in the system under the name "libiio.so". +So instead of kicking of this complicated cross-platform/cross-distro +compatible machinery, we just pass in the name of the library we already +know. + +[1] https://docs.python.org/3/library/ctypes.html#finding-shared-libraries + +Upstream: N/A, buildroot doesn't have to care about different OS's and +distro setups, so we can just hardcode the lib name, but we cannot +submit that upstream. + +Signed-off-by: Marcus Hoffmann +--- + bindings/python/iio.py | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/bindings/python/iio.py b/bindings/python/iio.py +index b91260cc..bde17694 100644 +--- a/bindings/python/iio.py ++++ b/bindings/python/iio.py +@@ -224,7 +224,7 @@ else: + # Non-windows, possibly Posix system + _iiolib = "iio" + +-_lib = _cdll(find_library(_iiolib), use_errno=True, use_last_error=True) ++_lib = _cdll("libiio.so", use_errno=True, use_last_error=True) + + _get_backends_count = _lib.iio_get_backends_count + _get_backends_count.restype = c_uint +-- +2.25.1 +
