Subject: Problem with Compress::LZO installation

Hello! I've got a problem with Compress::LZO installation. Due to the fact that LZO library has been installed painlessly, I suspect this might be a problem with the module itself. The problem appears when trying to "use" the module: $ perl -e "use Compress::LZO;" perl: symbol lookup error: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/Compress /LZO/LZO.so: undefined symbol: __lzo_init_v2 If you could investigate the problem and give me some clues, I'd be extremely grateful for your help! Here's all the important information: OS/arch: Linux/x86_64 Makefile.PL options: $LZO_INCLUDE = '-I/usr/local/include/lzo'; $LZO_LIB = '-L/usr/local/lib'; Console output: [tccbuild@neon Compress-LZO-1.08]$ ./configure Note (probably harmless): No library found for -llzo Writing Makefile for Compress::LZO $ make cp LZO.pm blib/lib/Compress/LZO.pm AutoSplitting blib/lib/Compress/LZO.pm (blib/lib/auto/Compress/LZO) /usr/bin/perl /usr/lib/perl5/5.8.8/ExtUtils/xsubpp -typemap /usr/lib/perl5/5.8.8/ExtUtils/typemap -typemap typemap LZO.xs > LZO.xsc && mv LZO.xsc LZO.c gcc -c -I/usr/local/include/lzo -D_REENTRANT -D_GNU_SOURCE -fno-strict-aliasing -pipe -Wdeclaration-after-statement -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gdbm -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -DVERSION=\"1.08\" -DXS_VERSION=\"1.08\" -fPIC "-I/usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/CORE" LZO.c LZO.xs: In function âXS_Compress__LZO_compressâ: LZO.xs:134: warning: pointer targets in assignment differ in signedness LZO.xs: In function âXS_Compress__LZO_decompressâ: LZO.xs:182: warning: pointer targets in assignment differ in signedness Running Mkbootstrap for Compress::LZO () chmod 644 LZO.bs rm -f blib/arch/auto/Compress/LZO/LZO.so gcc -shared -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic LZO.o -o blib/arch/auto/Compress/LZO/LZO.so \ \ chmod 755 blib/arch/auto/Compress/LZO/LZO.so cp LZO.bs blib/arch/auto/Compress/LZO/LZO.bs chmod 644 blib/arch/auto/Compress/LZO/LZO.bs Manifying blib/man3/Compress::LZO.3pm $ su Password: # make install Installing /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/Compress /LZO/LZO.so Installing /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/Compress /LZO/LZO.bs Files found in blib/arch: installing files in blib/lib into architecture dependent library tree Installing /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/Compress /LZO/autosplit.ix Installing /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/Compress/LZO. pm Installing /usr/share/man/man3/Compress::LZO.3pm Writing /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/Compress /LZO/.packlist Appending installation info to /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/perllocal.pod [root@neon Compress-LZO-1.08]# exit $ perl -e "use Compress::LZO;" perl: symbol lookup error: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/Compress /LZO/LZO.so: undefined symbol: __lzo_init_v2 If you need any more, please let me know!

This looks like some problem during linking - see the warning: Note (probably harmless): No library found for -llzo BTW, this is _not_ harmless. pawel.bol@comarch.com via RT wrote: Show quoted text

Hey! Thanks a lot for pointing that out... Now it works great for me! Here's what I did... First created the symlinks to LZO libraries, which helped me to get rid of the "Note (probably harmless): No library found for -llzo" message (by the way, I wouldn't guess that "probably harmless" could be meant "_not_ harmless"). # ln -s /usr/local/lib/liblzo2.a /usr/local/lib/liblzo.a # ln -s /usr/local/lib/liblzo2.la /usr/local/lib/liblzo.la During the "make" step, the following error appeared: /usr/bin/ld: /usr/local/lib/liblzo.a(lzo_crc.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC So I have recompiled the LZO libraries with the additional "-fPIC" flag. $ export CFLAGS=-fPIC $ ./configure $ make $ make test # make install After this, all of the module installation went perfectly! Thank you! Best regards, Pawel Bol.
