This builds the library libbz2.a and then the programs > 26 bzip2 and bzip2recover. Six self-tests are run.

This Makefile seems to work for > 51 Linux-ELF (RedHat 7.2 on an x86 box), with gcc. I make no claims > 52 that it works for any other platform, though I suspect it probably > 53 will work for most platforms employing both ELF and gcc. > 54 > 55 bzip2-shared, a client of the shared library, is also built, but not > 56 self-tested. So I suggest you also build using the normal Makefile, > 57 since that conducts a self-test. A second reason to prefer the > 58 version statically linked to the library is that, on x86 platforms, > 59 building shared objects makes a valuable register (%ebx) unavailable > 60 to gcc, resulting in a slowdown of 10%-20%, at least for bzip2. > 61 > 62 Important note for people upgrading .so's from 0.9.0/0.9.5 to version > 63 1.0.X. All the functions in the library have been renamed, from (eg) > 64 bzCompress to BZ2_bzCompress, to avoid namespace pollution. > 65 Unfortunately this means that the libbz2.so created by > 66 Makefile-libbz2_so will not work with any program which used an older > 67 version of the library. I do encourage library clients to make the > 68 effort to upgrade to use version 1.0, since it is both faster and more > 69 robust than previous versions. > 70 > 71 > 72 HOW TO BUILD -- Windows 95, NT, DOS, Mac, etc. > 73 > 74 It's difficult for me to support compilation on all these platforms. > 75 My approach is to collect binaries for these platforms, and put them > 76 on the master web site (http://www.bzip.org). Look there. However > 77 (FWIW), bzip2-1.0.X is very standard ANSI C and should compile > 78 unmodified with MS Visual C. If you have difficulties building, you > 79 might want to read README.COMPILATION.PROBLEMS. > 80 > 81 At least using MS Visual C++ 6, you can build from the unmodified > 82 sources by issuing, in a command shell: > 83 > 84 nmake -f makefile.msc > 85 > 86 (you may need to first run the MSVC-provided script VCVARS32.BAT > 87 so as to set up paths to the MSVC tools correctly). > 88 > 89 > 90 VALIDATION > 91 > 92 Correct operation, in the sense that a compressed file can always be > 93 decompressed to reproduce the original, is obviously of paramount > 94 importance. To validate bzip2, I used a modified version of Mark > 95 Nelson's churn program. Churn is an automated test driver which > 96 recursively traverses a directory structure, using bzip2 to compress > 97 and then decompress each file it encounters, and checking that the > 98 decompressed data is the same as the original. > 99 > 100 > 101 > 102 Please read and be aware of the following: > 103 > 104 WARNING: > 105 > 106 This program and library (attempts to) compress data by > 107 performing several non-trivial transformations on it. > 108 Unless you are 100% familiar with *all* the algorithms > 109 contained herein, and with the consequences of modifying them, > 110 you should NOT meddle with the compression or decompression > 111 machinery. Incorrect changes can and very likely *will* > 112 lead to disastrous loss of data. > 113 > 114 > 115 DISCLAIMER: > 116 > 117 I TAKE NO RESPONSIBILITY FOR ANY LOSS OF DATA ARISING FROM THE > 118 USE OF THIS PROGRAM/LIBRARY, HOWSOEVER CAUSED. > 119 > 120 Every compression of a file implies an assumption that the > 121 compressed file can be decompressed to reproduce the original. > 122 Great efforts in design, coding and testing have been made to > 123 ensure that this program works correctly. However, the complexity > 124 of the algorithms, and, in particular, the presence of various > 125 special cases in the code which occur with very low but non-zero > 126 probability make it impossible to rule out the possibility of bugs > 127 remaining in the program.

Specifically, the very > 160 slow performance caused by repetitive data is fixed. > 161 * Many small improvements in file and flag handling. > 162 * A Y2K statement. > 163 > 164 WHAT'S NEW IN 1.0.0 ? > 165 > 166 See the CHANGES file. > 167 > 168 WHAT'S NEW IN 1.0.2 ? > 169 > 170 See the CHANGES file. > 171 > 172 WHAT'S NEW IN 1.0.3 ? > 173 > 174 See the CHANGES file. > 175 > 176 WHAT'S NEW IN 1.0.4 ? > 177 > 178 See the CHANGES file. > 179 > 180 WHAT'S NEW IN 1.0.5 ? > 181 > 182 See the CHANGES file. > 183 > 184 WHAT'S NEW IN 1.0.6 ? > 185 > 186 See the CHANGES file. > 187 > 188 > 189 I hope you find bzip2 useful.
