I want to use the PSPP-Perl-Module, but it seem to be much harder than expected. I would be fine using any version of the module, but since it seems like one has to build it on every mashine (please correct my if I am wrong) I go for Ubuntu LTS versions:
pspp-0.7.9+git20120319 is the PSPP version in Ubuntu LTS 12.04.
First try: CPAN install
cpan PSPP:Sysfile
Will build a pretty old version
CPAN.pm: Going to build P/PD/PDONELAN/PSPP-Perl-0.7.2.20090730.tar.gz
and asks for a configured source directory which I don't have at the moment.
Enter the location of the build directory of the configured pspp source: []
Second try: apt-get source -b
cd ~
apt-get build-dep pspp
apt-get source -b pspp
Downloads the source of 0.7.9+git20120319 into the current directory and builds it. Building seems to work for quite a while but ends with an error in test phase:

The PSPP users mailinglist discussed some problems building the Perl-Module this January, and I quote:
Basically you are right, you will need to compile PSPP first, but you don't need
to install it. At a risk of contradicting that sentence, you should follow the
instructions in the file called INSTALL. However, to save yourself a bit of
time and from having to install lots of things you won't need, you can pass
various --without-* flags to configure, thus:
./configure --without-gui --without-cairo --without-libncurses
make
cd perl-module
make install
So with my unfinished build I entered the perl-module directory
cd pspp-0.7.9+git20120319/perl-module
make install

:-(
The file PSPP.so in question exists:
ls /usr/local/lib/perl/5.14.2/auto/PSPP
libpspp-0.7.9.so libpspp-core-0.7.9.so libpspp-core.so libpspp.so PSPP.bs PSPP.so
This is where I am stuck. Any hints on any approaches are very very welcome. My understanding is, that CPAN has an uploaded old version 0.7.2 of the PSPP-Module, but that the PSPP-Module is actually part of the main PSPP source. Why is the module not automatically installed on by mashine as part of apt-get install pspp. Is it? Am I too stupid to find/use it?
Many thanks in advance, Steve
Thanks to an answer on PSPP's friendy mailinglist, I found a solution:
ldd /usr/local/lib/perl/5.14.2/auto/PSPP/PSPP.so
linux-vdso.so.1 => (0x00007fffe23d2000)
libpspp-core-0.7.9.so => not found

/lib64/ld-linux-x86-64.so.2 (0x00007f7b6702c000)
Then I created a file
echo '/usr/local/lib/perl/5.14.2/auto/PSPP' > /etc/ld.so.conf.d/pspp.conf
ldconfig
And now it looks better!

I've followed all the instructions exactly - is there something I'm missing?
I'm compiling an executable called "interrogate" with:
g++ -o built/bin/interrogate -Lbuilt/lib -Lbuilt/tmp -L/usr/X11R6/lib \
built/tmp/interrogate_composite1.o built/tmp/interrogate_composite2.o \
-lp3cppParser -lp3dtool -lp3dtoolconfig -lp3pystub -pthread -ldl
After the compilation, when i try to execute the executable:
$ LD_LIBRARY_PATH=built/lib built/bin/interrogate
built/bin/interrogate: symbol lookup error: built/lib/libp3dtool.so.1.8: undefined symbol: _Py_NoneStruct
This symbol is provided by the libp3pystub.so, but the interrogate executable doesn't have any reference to this library (I did used the -lp3pystub):
$ LD_LIBRARY_PATH=built/lib ldd built/bin/interrogate

If i manually load the libp3pystub.so, the executable works:
$ LD_PRELOAD=built/lib/libp3pystub.so LD_LIBRARY_PATH=built/lib built/bin/interrogate
Usage:
interrogate [opts] file.C [file.C ...]
interrogate -h
My question is: why the library i've added with -lp3pystub is not referenced by the interrogate executable?
I actually find the answer myself. I was compiling on Ubuntu, and they added a default optimization flags: -Wl,--as-needed. This optimization check if no symbol from the libraries passed with -l are used in the main executable, they will be removed.
And that's where my error was: _Py_NoneStruct is not directly used by interrogate, but by another shared library. So i must manually specify that the p3pystub is needed.
One possible fix would be:
$ g++ -o built/bin/interrogate -Lbuilt/lib -Lbuilt/tmp -L/usr/X11R6/lib \
built/tmp/interrogate_composite1.o built/tmp/interrogate_composite2.o \
-Wl,--no-as-needed -lp3cppParser -lp3dtool -lp3dtoolconfig -lp3pystub \
-pthread -ldl
And then i correctly got the library in the ldd output:

How can I use bash to retrieve lib directory? For example: /usr/lib or /usr/lib64?
Edit
I'm packaging an RPM which copies some files to %{_libdir}. So I'd like to know the path to lib directory… I can use if [ -f "path-to-my-file" ]; then ... but I wonder if there is a command line?

libc.so.6 => /lib/libc.so.6 (0x0096c000)
libpthread.so.0 => /lib/libpthread.so.0 (0x00ab9000)
/lib/ld-linux.so.2 (0x00949000)
The binary path is /usr/local/lib/libre2.so.0.
Is there any way we can force compiler to pick the .so file from our preferred path?
Yes, there is a way: you can specify full path to the shared library when linking,e.g.:
Let my library is: libtest2.so (it is in /projects/tests/test_so)
Let my main program cpp file is: main.cpp
Then:
g++ main.cpp -o test /projects/tests/test_so/libtest2.so
Produces binary test which has embedded absolute path /projects/tests/test_so in it. No matter where you move the test binary it will always look for /projects/tests/test_so/libtest2.so
Alternatively you may look at -rpath switch that you can use with gcc (actually it is a linker switch),e.g:
gcc -Wl,-rpath,'<path-to-lib-directory>'
But this approach may cause your program to look also for other shared libraries in <path-to-lib-directory> which may not be exactly what you want.
