Re: [Discuss-gnuradio] CMake/SWIG build problems
Hi Rafael, I am preparing a release for the beginning of next week. The release will contain my DRM30 transmitter with various, fully configured flowgraphs that hopefully can be used more or less as-is and especially without deep knowledge of DRM. It's already working, but before releasing my code I want to put together a Readme file explaining how to install/use my software and what the constraints are. When everything is ready to be made public, I will notify the list about it. Currently I am implementing DRM+ support but I cannot say if it will make it into the first release. But as I mentioned before, this project doesn't end for me when GSoC ends. I already wrote to Michael Feilen and asked for a version of his DRM+ receiver software so that I can test my code. We got the same consumer receiver (DR111) here at my institute, but it's a preproduction sample as far as I know and it's quite buggy. Especially bandwidths above 10 kHz (spectrum occupancy 4 and 5) do not work with that receiver and unicode support for text messages is very limited. However, DREAM decodes the signal and so I guess I'm not doing everything wrong =). Best regards, Felix Hi Felix, Do you have something in a ready-to-test state concerning the DRM transmitter? I got a new DRM receiver (DR111) which shows the MER and SNR of the reception.

Hi Felix, Do you have something in a ready-to-test state concerning the DRM transmitter? I got a new DRM receiver (DR111) which shows the MER and SNR of the reception. Best regards, Rafael Diniz Hi Josh, That hint with the visibility option solved all my problems. I commented it out in the CMakeLists.txt and the undefined symbols were gone. Thank you so much! Best regards, Felix It compiles without any errors or warnings, but when I try to import my module, I get undefined symbol errors. I looked at the swig shared library file using nm and noticed that I have lots of undefined symbols in the part that contains my former drm_init module. The C++ shared library seems fine, so I guess it's a SWIG problem. You probably have some class or function thats defined in a header and either missing from the library or not exported. SWIG basically uses all of the functions/classes you feed it. So anything missing, so long as it was defined in a header you fed to swig, is going to be heard about when you import the module. Are you compiling with -fvisibility=hidden? you need to declare any public symbols to be default visibility http://gcc.gnu.org/wiki/Visibility Just a guess, -josh I would really appreciate it if somebody could give me a hint how I can configure CMake / SWIG correctly. The current (working) configuration can be found on github.com/fewu. The custom make file can be found under misc/, the other in the swig/ folder.

[Discuss-gnuradio] CMake/SWIG build problems
Hi all, I am currently preparing a release of my DRM transmitter blockset. This package shall contain my GNU Radio blocks and a set of classes (no blocks) used for initializing the transmitter parameters before the flow graph is started. At the moment, I have a source tree generated by gr_modtool based on CMake that contains my GNU Radio blocks and creates the python module drm and a second folder containing the classes for initializing where I wrote the .i file myself and compile everything by hand. This folder ends up in drm_init. Everything works fine if I do it like that but it's quite inconvenient. Now I'd like to combine these two build processes in the CMake build and the two modules in one. My first try was to add the source files in the CMakeLists file in lib/, the header files in include/. Then I added everything from my custom swig file in the existing one in swig/. It compiles without any errors or warnings, but when I try to import my module, I get undefined symbol errors. I looked at the swig shared library file using nm and noticed that I have lots of undefined symbols in the part that contains my former drm_init module. The C++ shared library seems fine, so I guess it's a SWIG problem. I would really appreciate it if somebody could give me a hint how I can configure CMake / SWIG correctly. The current (working) configuration can be found on github.com/fewu. The custom make file can be found under misc/, the other in the swig/ folder.
