Installation Issues and Debugging
Starting with LSL version 0.4.5, a installation and debugging script is included in the root directory of the LSL release. This script, gatherDebugging.py, probes the current Python installation to:
- Identify the version of Python that is being used,
- Check if the required Python modules are installed and usable,
- Check if the required C libraries are installed (Linux only),
- List detailed information about the Numpy installation and its linking, and
- List detailed information about the LSL installation and its linking.
For installation problems, the script helps identify missing modules or modules that do not import without error. For debugging, the script help identify linking problem (32 vs. 64-bit Numpy installations) and version problems.
Typical Output - Linux
A typical output of the script should look like:
Executable path: /usr/bin/python Platform: linux2 Version: 2.6.5 (r265:79063, Apr 16 2010, 13:57:41) [GCC 4.4.3] API: 1013 Bits: 64bit Linkage: ELF Numpy: version 1.3.0 Scipy: version 0.7.0 Pyfits: version 2.4.0 Ephem: version 18.104.22.168 Aipy: version unknown libatlas: found in /usr/lib libcblas: found in /usr/lib libfftw3: found in /usr/lib libnova: found in /usr/local/lib libgdbm: found in /usr/lib Numpy Path: /usr/lib/python2.6/dist-packages/numpy Numpy Version: 1.3.0 Numpy Linkage: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped LSL Path: /usr/local/lib/python2.6/dist-packages/lsl-0.5.dev_r654-py2.6-linux-x86_64.egg/lsl LSL Base Version: 0.5 LSL Linkage: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, not stripped

(from the fornax-mac build system).
Usage with Older LSL Version
The debugging script should be usable with all LSL 0.4.x releases prior to 0.4.5. To get a copy of the the script via subversion:
svn export http://fornax.phys.unm.edu/lwa/subversion/branches/lsl-0.4.x/gatherDebugging.py
