Compress-Raw-Bzip2 provides the interface to the bzip2 library for the modules IO::Compress::Bzip2 and IO::Compress::Bunzip2.
Before you can build Compress-Raw-Bzip2 you need to have the following installed on your system:
Assuming you have met all the prerequisites, the module can now be built using this sequence of commands:
perl Makefile.PL
make
make test
To install Compress-Raw-Bzip2, run the command below:
make install
If you are trying to build this module under Solaris and you get an error message like this
/usr/ucb/cc: language optional software package not installed
it means that Perl cannot find the C compiler on your system. The cryptic message is just Sun's way of telling you that you haven't bought their C compiler.
When you build a Perl module that needs a C compiler, the Perl build system tries to use the same C compiler that was used to build perl itself. In this case your Perl binary was built with a C compiler that lived in /usr/ucb.
To continue with building this module, you need to get a C compiler, or tell Perl where your C compiler is, if you already have one.
Assuming you have now got a C compiler, what you do next will be dependent on what C compiler you have installed. If you have just installed Sun's C compiler, you shouldn't have to do anything. Just try rebuilding this module.
If you have installed another C compiler, say gcc, you have to tell perl how to use it instead of /usr/ucb/cc.
This set of options seems to work if you want to use gcc. Your mileage may vary.
perl Makefile.PL CC=gcc CCCDLFLAGS=-fPIC OPTIMIZE=" " make test
If that doesn't work for you, it's time to make changes to the Makefile by hand. Good luck!
You are running Solaris and you get an error like this when you try to build this Perl module
gcc: unrecognized option `-KPIC'
This symptom usually means that you are using a Perl binary that has been built with the Sun C compiler, but you are using gcc to build this module.
When Perl builds modules that need a C compiler, it will attempt to use the same C compiler and command line options that was used to build perl itself. In this case "-KPIC" is a valid option for the Sun C compiler, but not for gcc. The equivalent option for gcc is "-fPIC".
The solution is either:
perl Makefile.PL CC=gcc CCCDLFLAGS=-fPIC OPTIMIZE=" " LD=gcc
make test
This second option seems to work when mixing a Perl binary built
with the Sun C compiler and this module built with gcc. Your
mileage may vary.
I've had a report that when building Compress-Raw-Bzip2 under HP-UX that it is necessary to have first built the bzip2 library with the -fpic option.
How to report a problem with Compress-Raw-Bzip2.
To help me help you, I need all of the following information:
perl -V
Do not edit the output in any way.
Note, I want you to run "perl -V" and NOT "perl -v".
If your perl does not understand the "-V" option it is too
old. This module needs Perl version 5.004 or better.
b. The version of Compress-Raw-Bzip2 you have.
If you have successfully installed Compress-Raw-Bzip2, this one-liner
will tell you:
perl -MCompress::Raw::Bzip2 -e 'print qq[ver $Compress::Raw::Bzip2::VERSION\n]'
If you are running windows use this
perl -MCompress::Raw::Bzip2 -e "print qq[ver $Compress::Raw::Bzip2::VERSION\n]"
If you haven't installed Compress-Raw-Bzip2 then search Compress::Raw::Bzip2.pm
for a line like this:
$VERSION = "2.037" ;
c. The version of bzip2 you have used.
If you have successfully installed Compress-Raw-Bzip2, this one-liner
will tell you:
perl -MCompress::Raw::Bzip2 -e "print q[bzip2 ver ]. Compress::Raw::Bzip2::ZLIB_VERSION.qq[\n]"
If not, look at the beginning of the file zlib.h.
2. If you are having problems building Compress-Raw-Bzip2, send me a
complete log of what happened. Start by unpacking the Compress-Raw-Bzip2 module into a fresh directory and keep a log of all the steps
[edit config.in, if necessary]
