| 19 | DESCRIPTION |
| 20 | ----------- |
| 21 | |
| 22 | Compress-Raw-Bzip2 provides the interface to the bzip2 library for the modules |
| 23 | IO::Compress::Bzip2 and IO::Compress::Bunzip2. |
| 24 | |
| 25 | PREREQUISITES |
| 26 | ------------- |
| 27 | |
| 28 | Before you can build Compress-Raw-Bzip2 you need to have the following |
| 29 | installed on your system: |
| 30 | |
| 31 | * A C compiler |
| 32 | |
| 33 | * Perl 5.004 or better. |
| 34 | |
| 35 | BUILDING THE MODULE |
| 36 | ------------------- |
| 37 | |
| 38 | Assuming you have met all the prerequisites, the module can now be built |
| 39 | using this sequence of commands: |
| 40 | |
| 41 | perl Makefile.PL |
| 42 | make |
| 43 | make test |
| 44 | |
| 45 | INSTALLATION |
| 46 | ------------ |
| 47 | |
| 48 | To install Compress-Raw-Bzip2, run the command below: |
| 49 | |
| 50 | make install |
| 51 | |
| 52 | TROUBLESHOOTING |
| 53 | --------------- |
| 54 | |
| 55 | Solaris build fails with "language optional software package not installed" |
| 56 | --------------------------------------------------------------------------- |
| 57 | |
| 58 | If you are trying to build this module under Solaris and you get an |
| 59 | error message like this |
| 60 | |
| 61 | /usr/ucb/cc: language optional software package not installed |
| 62 | |
| 63 | it means that Perl cannot find the C compiler on your system. The cryptic |
| 64 | message is just Sun's way of telling you that you haven't bought their |
| 65 | C compiler. |
| 66 | |
| 67 | When you build a Perl module that needs a C compiler, the Perl build |
| 68 | system tries to use the same C compiler that was used to build perl |
| 69 | itself. In this case your Perl binary was built with a C compiler that |
| 70 | lived in /usr/ucb. |
| 71 | |
| 72 | To continue with building this module, you need to get a C compiler, |
| 73 | or tell Perl where your C compiler is, if you already have one. |
| 74 | |
| 75 | Assuming you have now got a C compiler, what you do next will be dependent |
| 76 | on what C compiler you have installed. If you have just installed Sun's |
| 77 | C compiler, you shouldn't have to do anything. Just try rebuilding |
| 78 | this module. |
| 79 | |
| 80 | If you have installed another C compiler, say gcc, you have to tell perl |
| 81 | how to use it instead of /usr/ucb/cc. |
| 82 | |
| 83 | This set of options seems to work if you want to use gcc. Your mileage |
| 84 | may vary. |
| 85 | |
| 86 | perl Makefile.PL CC=gcc CCCDLFLAGS=-fPIC OPTIMIZE=" " |
| 87 | make test |
| 88 | |
| 89 | If that doesn't work for you, it's time to make changes to the Makefile |
| 90 | by hand. Good luck! |
| 91 | |
| 92 | Solaris build fails with "gcc: unrecognized option `-KPIC'" |
| 93 | ----------------------------------------------------------- |
| 94 | |
| 95 | You are running Solaris and you get an error like this when you try to |
| 96 | build this Perl module |
| 97 | |
| 98 | gcc: unrecognized option `-KPIC' |
| 99 | |
| 100 | This symptom usually means that you are using a Perl binary that has been |
| 101 | built with the Sun C compiler, but you are using gcc to build this module. |
| 102 | |
| 103 | When Perl builds modules that need a C compiler, it will attempt to use |
| 104 | the same C compiler and command line options that was used to build perl |
| 105 | itself. In this case "-KPIC" is a valid option for the Sun C compiler, |
| 106 | but not for gcc. The equivalent option for gcc is "-fPIC". |
| 107 | |
| 108 | The solution is either: |
| 109 | |
| 110 | 1. Build both Perl and this module with the same C compiler, either |
| 111 | by using the Sun C compiler for both or gcc for both. |
| 112 | |
| 113 | 2. Try generating the Makefile for this module like this perl |
| 114 | |
| 115 | perl Makefile.PL CC=gcc CCCDLFLAGS=-fPIC OPTIMIZE=" " LD=gcc |
| 116 | make test |
| 117 | |
| 118 | This second option seems to work when mixing a Perl binary built |
| 119 | with the Sun C compiler and this module built with gcc. Your |
| 120 | mileage may vary. |
| 121 | |
| 122 | HP-UX Notes |
| 123 | ----------- |
| 124 | |
| 125 | I've had a report that when building Compress-Raw-Bzip2 under HP-UX that it |
| 126 | is necessary to have first built the bzip2 library with the -fpic |
| 127 | option. |
| 128 | |
| 129 | FEEDBACK |
| 130 | -------- |
| 131 | |
| 132 | How to report a problem with Compress-Raw-Bzip2. |
| 133 | |
| 134 | To help me help you, I need all of the following information: |
| 135 | |
| 136 | 1. The Versions of everything relevant. |
| 137 | This includes: |
| 138 | |
| 139 | a. The *complete* output from running this |
| 140 | |
| 141 | perl -V |
| 142 | |
| 143 | Do not edit the output in any way. |
| 144 | Note, I want you to run "perl -V" and NOT "perl -v". |
| 145 | |
| 146 | If your perl does not understand the "-V" option it is too |
| 147 | old. This module needs Perl version 5.004 or better. |
| 148 | |
| 149 | b. The version of Compress-Raw-Bzip2 you have. |
| 150 | If you have successfully installed Compress-Raw-Bzip2, this one-liner |
| 151 | will tell you: |
| 152 | |
| 153 | perl -MCompress::Raw::Bzip2 -e 'print qq[ver $Compress::Raw::Bzip2::VERSION\n]' |
| 154 | |
| 155 | If you are running windows use this |
| 156 | |
| 157 | perl -MCompress::Raw::Bzip2 -e "print qq[ver $Compress::Raw::Bzip2::VERSION\n]" |
| 158 | |
| 159 | If you haven't installed Compress-Raw-Bzip2 then search Compress::Raw::Bzip2.pm |
| 160 | for a line like this: |
| 161 | |
| 162 | $VERSION = "2.015" ; |
| 163 | |
| 164 | c. The version of bzip2 you have used. |
| 165 | If you have successfully installed Compress-Raw-Bzip2, this one-liner |
| 166 | will tell you: |
| 167 | |
| 168 | perl -MCompress::Raw::Bzip2 -e "print q[bzip2 ver ]. Compress::Raw::Bzip2::ZLIB_VERSION.qq[\n]" |
| 169 | |
| 170 | If not, look at the beginning of the file zlib.h. |
| 171 | |
| 172 | 2. If you are having problems building Compress-Raw-Bzip2, send me a |
| 173 | complete log of what happened. Start by unpacking the Compress-Raw-Bzip2 |
| 174 | module into a fresh directory and keep a log of all the steps |
| 175 | |
| 176 | [edit config.in, if necessary] |
| 177 | perl Makefile.PL |
| 178 | make |
| 179 | make test TEST_VERBOSE=1 |
