Cannot install Gzip::Faster : tests are failing

peroumal1 commented 10 years ago

Hello,

I just tried to install with cpanm Gzip::Faster on my server and the tests have failed.

My environment : perl 5.012002 built for x86_64-linux

The error I get :

 
Can't load '~/.cpanm/work/1409191837.20471/Gzip-Faster-0.09/blib/arch/auto/Gzip/Faster/Faster.so' for module Gzip::Faster: ~/.cpanm/work/1409191837.20471/Gzip-Faster-0.09/blib/arch/auto/Gzip/Faster/Faster.so: undefined symbol: inflate at ~/perl5/perlbrew/perls/perl-5.12.2/lib/5.12.2/x86_64-linux/DynaLoader.pm line 200.
 at t/gzip-faster.t line 7.

Can you help ?

Thanks !

The section

undefined symbol: inflate

looks like it's trying to dynamically link to zlib but cannot find it.

Please run the following:

 make clean
 perl Makefile.PL > make.log
 make >> make.log
 make test >> make.log

and post the file make.log here.

So with the instructions you provided, here is the make.log :

I also noticed the following from STDERR (not in the make.log) when running 'perl Makefile.PL' :

 
Warning (mostly harmless): No library found for -lz

Could it be the source of what I am experiencing ? Maybe I'm missing a library in my environment ?

Yes, you seem to be missing libz (zlib). The module won't work without that. What Linux is it? If it's something like Ubuntu, you might need to do something like

 sudo apt-get install zlib1g-dev

Please could you let me know what happens.

benkasminbullock commented 10 years ago

My guess is that this was the problem. I've added a note to the module documentation in 79da4f1490cf8208632a7bc697a0a53cff996730, and I'm closing the issue. @peroumal1, please reopen the issue if this does not solve the problem.

peroumal1 commented 10 years ago

The library was already installed on my system, so it's not coming from here. I'm using Ubuntu 12.04.

benkasminbullock commented 10 years ago

The zlib library may be installed on your system, but is the above zlib1g-dev installed?

benkasminbullock commented 10 years ago

If you have no response, I'll assume the library was not installed and that was the problem.

peroumal1 commented 10 years ago

Hey, I was sleeping, that is why I had no response. Thanks anyway for your support, I'll be using another module. Le 28 août 2014 07:03, "Ben Bullock" notifications@github.com a écrit :

OK then. Good luck with the other module.
