Fedora Core 5 x86_64 lib install problems

GNU Radio
1

I’m having issues getting the gnu-radio core libraries installed in the
correct location on my 64-bit installation of Fedora Core 5. The
problem
appears to be the separation of the 32-bit and 64-bit libraries. I
compiled with:
./for-all-dirs …/buildit -n --prefix=$HOME/z.research/z.gnuradio

After compiling gnuradio-core successfully, gr-audio-alsa fails in the
check stage with this error:

make[3]: Entering directory
`/home/matlis/z.research/z.gnuradio/gr-build/gr-audio-alsa/src’
Traceback (most recent call last):
File “./qa_alsa.py”, line 23, in ?

ImportError: No module named _gnuradio_swig_python
FAIL: run_tests

The test routine is looking in …lib/python2.4 - shouldn’t it look in
lib64? This is where _gnuradio_swig_python.so is stored. I noticed
“run_tests” in the gr_audio_alsa/src directory contained the following:

Where to look for installed GNU Radio python modules

FIXME this is wrong on a distcheck. We really need to ask

gnuradio-core

where it put its python files.

installed_pythondir=${prefix}/lib/python2.4/site-packages
installed_pyexecdir=${exec_prefix}/lib64/python2.4/site-packages

I noticed the first line referes to lib as opposed to lib64, but
changing
this to lib64 didn’t seem to fix the problem.

Here are my environment variables defind in .bash_profile:

GR=$HOME/z.research/z.gnuradio
export GR
PATH=$PATH:.:$GR/bin
export PKG_CONFIG_PATH=$GR/lib64/pkgconfig/:/usr/lib64/pkgconfig
export
PYTHONPATH=$GR/lib64/python2.4/site-packages:/usr/lib64/python2.4/site-packages
export LD_LIBRARY_PATH=$GR/lib64
export CVS_RSH=ssh
export LDFLAGS="-L$GR/lib"

Any suggestions?

thanks!

This shouldn’t matter in your case. It’s a warning about
(patholigical) cases where gnuradio-core is installed in a different
prefix than what you’re trying to build. It is strange that the two
path are different however…

export LDFLAGS="-L$GR/lib"

Any suggestions?

Is PYTHONPATH already exported?

Does your system have a /lib64 directory?
Does it contain both 32-bit and 64-bit libraries for at least some
parts?

Answering my own query… The two lines should be different. One is
the library path (which has the lib64), the other is the “execpath”.

Eric,

I just tried this on my X86_64 running SuSE 9.3. Worked fine for me
on a fresh checkout from CVS. The output of

$ ./for-all-dirs …/buildit --prefix=/home/eb/test/install 2>&1 | tee
make.log

is here: http://comsec.com/make.log

Perhaps you can figure out what’s different between the two runs?
I suggest examining the output of configure for gnuradio-core and
gr-audio-alsa. I didn’t set any environment variables to special
values. I just used buildit and the normal values I use for building
with the default prefix (/usr/local).

Here are my tool versions:

$ uname -a

PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig:/usr/local/lib/pkgconfig:/usr/lib64/pkgconfig:/opt/gnome/lib64/pkgconfig

I do NOT have LD_LIBRARY_PATH set.

FYI, I removed all GNU Radio stuff from /usr/local/* before doing this
build
with the non-default prefix.
