Ice-related Build Problem

Building GR with the latest pybombs completes successfully, but when
calling a GR binary, there’s an error about ICE (which built without
problems):

$:~/pybombs/src/gnuradio/build$ gnuradio-config-info -v
gnuradio-config-info: error while loading shared libraries:
libIce.so.35:
cannot open shared object file: No such file or directory

This is on Ubuntu 12.04 x64

Very Respectfully,

Running find to search for the missing library does find it at:

/usr/lib64/libIce.so.35

These ‘cannot open shared object file’ errors are usually solved for me
by
running ‘sudo ldconfig’.

Pybombs should not be run as root as everything gets installed to the
target directory.

You need to run ‘./pybombs env’ and append the line about ‘source
…’
to your home directory’s ‘.bashrc’ file.

Thanks, Tom! See my comments in context below:

Wait, why do you have a lib64 on an Ubuntu machine? But, we do check in
lib64, so that shouldn’t be the problem.

I don’t know, but I do have ia32-libs installed on all of my nodes. It
had
been necessary in the past for one of our binaries, but may no longer be
so.

However, package management is not one of ZeroC’s strong suits, as Philip
and I can attest to with the OE recipe work… And finding the libraries is
a pain as well.

Do you have /usr/include/Ice*? And specifically,
/usr/include/IceUtil/Config.h. We use that to test if the Ice dev files are
there, and if so, extract the version number from it.

I do have those directories and the specific file you mentioned.

Things seem to be completely different for Ice 3.4 and Ice 3.5 and on
different versions of Ubuntu as well as other distros. It’s kind of a mess.
Can you get the CMake output for me? For the latest Ice 3.5 cmake script,
there’s a lot more output info to see what’s happening.

Sure. I assume you mean for gnuradio and no Ice.

Tom,

Interestingly, when I was retesting the cmake output for you, I built it
manually after that and it worked this time - no ice complaints. So,
the
problem seems likely to be somehow brought out when pybombs does the
build
(maybe passing options that I did not when compiling manually).

The original problem was on multiple machines and across multiple tries
to
build with pybombs, so this final success was definitely the result of
something done differently.

Very Respectfully,

Dan CaJacob
