27 Compress-Raw-Bzip2 provides the interface to the bzip2 library for the modules
28 IO::Compress::Bzip2 and IO::Compress::Bunzip2.
33 Before you can build Compress-Raw-Bzip2 you need to have the following
34 installed on your system:
38 * Perl 5.006 or better.
43 Assuming you have met all the prerequisites, the module can now be built
44 using this sequence of commands:
53 To install Compress-Raw-Bzip2, run the command below:
60 Solaris build fails with "language optional software package not installed"
61 ---------------------------------------------------------------------------
63 If you are trying to build this module under Solaris and you get an
64 error message like this
66 /usr/ucb/cc: language optional software package not installed
68 it means that Perl cannot find the C compiler on your system. The cryptic
69 message is just Sun's way of telling you that you haven't bought their
72 When you build a Perl module that needs a C compiler, the Perl build
73 system tries to use the same C compiler that was used to build perl
74 itself. In this case your Perl binary was built with a C compiler that
77 To continue with building this module, you need to get a C compiler,
78 or tell Perl where your C compiler is, if you already have one.
80 Assuming you have now got a C compiler, what you do next will be dependent
81 on what C compiler you have installed. If you have just installed Sun's
82 C compiler, you shouldn't have to do anything. Just try rebuilding
85 If you have installed another C compiler, say gcc, you have to tell perl
86 how to use it instead of /usr/ucb/cc.
88 This set of options seems to work if you want to use gcc. Your mileage
91 perl Makefile.PL CC=gcc CCCDLFLAGS=-fPIC OPTIMIZE=" "
94 If that doesn't work for you, it's time to make changes to the Makefile
97 Solaris build fails with "gcc: unrecognized option `-KPIC'"
98 -----------------------------------------------------------
100 You are running Solaris and you get an error like this when you try to
101 build this Perl module
103 gcc: unrecognized option `-KPIC'
105 This symptom usually means that you are using a Perl binary that has been
106 built with the Sun C compiler, but you are using gcc to build this module.
108 When Perl builds modules that need a C compiler, it will attempt to use
109 the same C compiler and command line options that was used to build perl
110 itself. In this case "-KPIC" is a valid option for the Sun C compiler,
111 but not for gcc. The equivalent option for gcc is "-fPIC".
113 The solution is either:
115 1. Build both Perl and this module with the same C compiler, either
116 by using the Sun C compiler for both or gcc for both.
118 2. Try generating the Makefile for this module like this perl
120 perl Makefile.PL CC=gcc CCCDLFLAGS=-fPIC OPTIMIZE=" " LD=gcc
123 This second option seems to work when mixing a Perl binary built
124 with the Sun C compiler and this module built with gcc. Your
130 I've had a report that when building Compress-Raw-Bzip2 under HP-UX that it
131 is necessary to have first built the bzip2 library with the -fpic
137 How to report a problem with Compress-Raw-Bzip2.
139 To help me help you, I need all of the following information:
141 1. The Versions of everything relevant.
144 a. The *complete* output from running this
148 Do not edit the output in any way.
149 Note, I want you to run "perl -V" and NOT "perl -v".
151 If your perl does not understand the "-V" option it is too
152 old. This module needs Perl version 5.004 or better.
154 b. The version of Compress-Raw-Bzip2 you have.
155 If you have successfully installed Compress-Raw-Bzip2, this one-liner
158 perl -MCompress::Raw::Bzip2 -e 'print qq[ver $Compress::Raw::Bzip2::VERSION\n]'
160 If you are running windows use this
162 perl -MCompress::Raw::Bzip2 -e "print qq[ver $Compress::Raw::Bzip2::VERSION\n]"
164 If you haven't installed Compress-Raw-Bzip2 then search Compress::Raw::Bzip2.pm
165 for a line like this:
169 c. The version of bzip2 you have used.
170 If you have successfully installed Compress-Raw-Bzip2, this one-liner
173 perl -MCompress::Raw::Bzip2 -e "print q[bzip2 ver ]. Compress::Raw::Bzip2::ZLIB_VERSION.qq[\n]"
175 If not, look at the beginning of the file zlib.h.
177 2. If you are having problems building Compress-Raw-Bzip2, send me a
178 complete log of what happened. Start by unpacking the Compress-Raw-Bzip2
179 module into a fresh directory and keep a log of all the steps
181 [edit config.in, if necessary]
