Compress-Raw-Bzip2 Version 2.086 31 March 2019 Copyright (c) 2005-2019 Paul Marquess. All rights reserved. This program is free software; you can redistribute it and/or modify it under the same terms as Perl itself. The directory bzip2-src contains a subset of the source files copied directly from bzip2 version 1.0.6. These files are Copyright(C) 1996-2010 Julian Seward. See the file bzip2-src/LICENSE for licence details for these files. Full source for the bzip2 library is available at http://www.bzip.org/ Note that the files bzip2.c, bzip2recover.c, bzlib.c & decompress.c have been modified to allow them to build with a C++ compiler. The file bzip2-src/bzip2-cpp.patch contains the patch that was used to modify the original source. DESCRIPTION ----------- Compress-Raw-Bzip2 provides the interface to the bzip2 library for the modules IO::Compress::Bzip2 and IO::Compress::Bunzip2. PREREQUISITES ------------- Before you can build Compress-Raw-Bzip2 you need to have the following installed on your system: * A C compiler * Perl 5.006 or better. BUILDING THE MODULE ------------------- Assuming you have met all the prerequisites, the module can now be built using this sequence of commands: perl Makefile.PL make make test INSTALLATION ------------ To install Compress-Raw-Bzip2, run the command below: make install TROUBLESHOOTING --------------- Solaris build fails with "language optional software package not installed" --------------------------------------------------------------------------- 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! Solaris build fails with "gcc: unrecognized option `-KPIC'" ----------------------------------------------------------- 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: 1. Build both Perl and this module with the same C compiler, either by using the Sun C compiler for both or gcc for both. 2. Try generating the Makefile for this module like this perl 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. HP-UX Notes ----------- 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. FEEDBACK -------- How to report a problem with Compress-Raw-Bzip2. To help me help you, I need all of the following information: 1. The Versions of everything relevant. This includes: a. The *complete* output from running this 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 = "2.086" ; 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] perl Makefile.PL make make test TEST_VERBOSE=1 Paul Marquess <firstname.lastname@example.org>
