ImportError : Undefined symbol
Hey
I get that this error means I screwed up somewhere in installation. Or some libraries are not being linked. But, I can't figure out how which library has to be linked and how.
Originally, I wanted to install PAL2 in a virtual environment. Everything went smoothly but when I tried to import libstempo, I got undefined symbol error.
I was able to run and import libstempo in my original environment just fine. I think there is some library not being found/linked when I do it in that virtual environment.
Can you shed some light on this?
Traceback (most recent call last): File "<string>", line 1, in <module> File "/home/shining/anaconda2/envs/pal2_conda/lib/python2.7/site-packages/libstempo/__init__.py", line 8, in <module> from libstempo.libstempo import * ImportError: /home/shining/mega/PDA/lib/libtempo2.so.2: undefined symbol: omp_get_thread_num
This is actually a problem with the tempo2 library, not libstempo. Recent versions use openmp, so you need to compile tempo2 with something that supports it. On the Mac, I use Homebrew-installed llvm (brew install llvm) and then do (export CC=/usr/local/opt/llvm/bin/clang; export CXX=/usr/local/opt/llvm/bin/clang++) before configuring tempo2. If you have a recent gcc through Homebrew or Macports, that could work also. There may be also compilers available through Anaconda, I’m not sure.
