gikotim has asked for the wisdom of the Perl Monks concerning the following question:

Hi I desperately try to compile a module which needs an external library (without root access). I have compiled the library and put it (and the header-files) under /home/rolf/local/lib & /home/rolf/local/include Then I run the perl Make: 
perl Makefile.PL LIBS=-L/usr/home/rolf/local/lib
INC=-I/usr/home/rolf/local/include 
INSTALL_BASE=/usr/home/rolf/local

This runs without any complains. Than make 
cp lib/SwissEph.pm blib/lib/SwissEph.pm
/usr/bin/perl /usr/local/lib/perl5/5.8.9/ExtUtils/xsubpp  -typemap /us
+r/local/lib/perl5/5.8.9/ExtUtils/typemap  SwissEph.xs > SwissEph.xsc 
+&& mv SwissEph.xsc SwissEph.c

Re: compile perl module without root and extra library
by Anonymous Monk on Jan 12, 2010 at 08:47 UTC
    LIBS is supposed to be
    -L/some/path/to/lib -lnameOfYourLib
    where nameOfYourLib defines swe_pheno

    Also, if nameOfYourLib is a dynamic library, you're supposed to set LD_LOAD_PATH to point to /some/path/to/lib

[reply]
      ok, here what I did: perl Makefile.PL LIBS=-L/usr/home/rolf/local/lib -lswe INC=-I/usr/home/rolf/local/include INSTALL_BASE=/usr/home/rolf/local make test -> same error msg make sure that the lib is correct: 
      file /usr/home/rolf/local/lib/libswe.so     
/usr/home/rolf/local/lib/libswe.so: ELF 32-bit LSB shared object, Inte
+l 80386, version 1 (FreeBSD), dynamically linked, not stripped

strings /usr/home/rolf/local/lib/libswe.so|grep swe_pheno
swe_pheno
swe_pheno_ut

      Any other idea, what I'm doing wrong? Many thanks for your help

        I think that should be LIBS="-L/usr/home/rolf/local/lib -lswe" (note the quotes). Also, the A.M. probably meant LD_LIBRARY_PATH. As an alternative to the latter, try passing the -rpath option to the linker (to compile in the run-time lib search path).

        As a quick fix, simply manually run (from the directory where SwissEph.o resides): 

        $ cc -shared -L/usr/local/lib SwissEph.o -o blib/arch/auto/SwissEph/Sw
+issEph.so -L/usr/home/rolf/local/lib -lswe -Wl,-rpath,/usr/home/rolf/
+local/lib
