I’ve just reinstalled gnuradio yesterday, using PyBOMBS. The newly installed version is gnuradio 3.7.4. The installation succeeded, but it then failed to compile my custom module which worked flawlessly with previous gnuradio installation. The previous version was gnuradio 3.7.3 which was installed using build-gunuradio, which had no problem at all. Compilation error: ``` Linking CXX shared library libgnuradio-activecat.so [71%] Built target gnuradio-activecat Scanning dependencies of target test-activecat [72%] Building CXX object ``` lib/CMakeFiles/test-activecat.dir/test\_activecat.cc.o [74%] Building CXX object lib/CMakeFiles/test-activecat.dir/qa\_activecat.cc.o Linking CXX executable test-activecat /usr/bin/ld: CMakeFiles/test-activecat.dir/test\_activecat.cc.o: undefined reference to symbol ‘\_ZN5boost10filesystem6detail16create\_directoryERKNS0\_4pathEPNS\_6system10error\_codeE’ /usr/bin/ld: note: ‘\_ZN5boost10filesystem6detail16create\_directoryERKNS0\_4pathEPNS\_6system10error\_codeE’ is defined in DSO /home/sgku/download/gnuradio/target/lib/libboost\_filesystem-mt.so.1.53.0 so try adding it to the linker command line /home/sgku/download/gnuradio/target/lib/libboost\_filesystem-mt.so.1.53.0: could not read symbols: Invalid operation collect2: error: ld returned 1 exit status make[2]: \*\*\* [lib/test-activecat] Error 1 make[1]: \*\*\* [lib/CMakeFiles/test-activecat.dir/all] Error 2 make: \*\*\* [all] Error 2 System info: ``` sgku@rs: ~ $ gnuradio-config-info -v v3.7.4git-257-gcb0bc7f0 sgku@rs: ~ $ uname -a Linux rs 3.2.0-4-686-pae #1 SMP Debian 3.2.57-3+deb7u1 i686 ``` GNU/Linux How to solve this? ---

Solution: Reinstall gnuradio using PyBOMBS, make sure prefix=/usr/local Note: During PyBOMBS install wizard, we are prompted for prefix, which defaults to ../target If we just press ENTER to accept the default value, then the prefix becomes something like /home/user1/download/gnuradio/target. But regardless of what has been configured for the prefix, the OOT (out-of-tree module) will be install into /usr/local. Since the newly generated setup\_env.sh does not include /usr/local, above error could occur. ---

FYI, I don’t like installing stuff to /usr/local. If you take PyBombs’ directory, and then use -DCMAKE\_INSTALL\_PREFIX on your own OOT, that’ll make both work and you don’t have to screw around in your system’s dirs. M ---

Is there any way to “hard code” this install\_prefix into the OOT setting file, so that we just need “cmake ../” in the OOT build directory? ---

Thanks, I’ve found the answer at > **[\[CMake\] cmake . -DCMAKE\_INSTALL\_PREFIX=/foo broken on solaris and hpux](https://cmake.org/pipermail/cmake/2007-September/016565.html)** ---

The block also doesn’t show up in the block tree. Instead of /home/user1/download/gnuradio/target/lib/python2.7/dist-packages/activecat/abc.py, it wrongly installed to /usr/local/lib/python2.7/dist-packages/activecat/abc.py As a result I have to copy it manually to the correct location. It seems PyBOMBS is still very problematic. ---

I’m failing to see how your hand installation of your own OOT module has anything to do with PyBOMBS? Tom
