Hello,
I've created my own GR module with GR mod tool. I added two files
include/my_mod/crc.h
lib/crc.cc
And I can use the functions (crc32 for example) in those files perfectly fine within classes that wind up in libgnuradio-my_mod.so. However, I can't use the functions in crc.h/crc.cc in external applications that link to libgnuradio-my_mod.so.
The correct symbols exist in libgnuradio-my_mod.so however the symbols are local, not global.
$ readelf -a lib/libgnuradio-my_mod.so | grep crc32
192: 0000000000228440 1024 OBJECT LOCAL DEFAULT 24 crc32_tab
426: 000000000000f3f0 52 FUNC LOCAL DEFAULT 11 _Z5crc32jPKvm
How can I expose crc32 to the outside world? Do I have to make the change in one of my CMakeLists.txt files or one of the source files? The function (crc32) isn't a static.
