1*4a711beaSLionel Sambuc------------------------------------------------------------------ 2*4a711beaSLionel SambucThis file is part of bzip2/libbzip2, a program and library for 3*4a711beaSLionel Sambuclossless, block-sorting data compression. 4*4a711beaSLionel Sambuc 5*4a711beaSLionel Sambucbzip2/libbzip2 version 1.0.6 of 6 September 2010 6*4a711beaSLionel SambucCopyright (C) 1996-2010 Julian Seward <jseward@bzip.org> 7*4a711beaSLionel Sambuc 8*4a711beaSLionel SambucPlease read the WARNING, DISCLAIMER and PATENTS sections in the 9*4a711beaSLionel SambucREADME file. 10*4a711beaSLionel Sambuc 11*4a711beaSLionel SambucThis program is released under the terms of the license contained 12*4a711beaSLionel Sambucin the file LICENSE. 13*4a711beaSLionel Sambuc------------------------------------------------------------------ 14*4a711beaSLionel Sambuc 15*4a711beaSLionel Sambucbzip2-1.0.6 should compile without problems on the vast majority of 16*4a711beaSLionel Sambucplatforms. Using the supplied Makefile, I've built and tested it 17*4a711beaSLionel Sambucmyself for x86-linux and amd64-linux. With makefile.msc, Visual C++ 18*4a711beaSLionel Sambuc6.0 and nmake, you can build a native Win32 version too. Large file 19*4a711beaSLionel Sambucsupport seems to work correctly on at least on amd64-linux. 20*4a711beaSLionel Sambuc 21*4a711beaSLionel SambucWhen I say "large file" I mean a file of size 2,147,483,648 (2^31) 22*4a711beaSLionel Sambucbytes or above. Many older OSs can't handle files above this size, 23*4a711beaSLionel Sambucbut many newer ones can. Large files are pretty huge -- most files 24*4a711beaSLionel Sambucyou'll encounter are not Large Files. 25*4a711beaSLionel Sambuc 26*4a711beaSLionel SambucEarly versions of bzip2 (0.1, 0.9.0, 0.9.5) compiled on a wide variety 27*4a711beaSLionel Sambucof platforms without difficulty, and I hope this version will continue 28*4a711beaSLionel Sambucin that tradition. However, in order to support large files, I've had 29*4a711beaSLionel Sambucto include the define -D_FILE_OFFSET_BITS=64 in the Makefile. This 30*4a711beaSLionel Sambuccan cause problems. 31*4a711beaSLionel Sambuc 32*4a711beaSLionel SambucThe technique of adding -D_FILE_OFFSET_BITS=64 to get large file 33*4a711beaSLionel Sambucsupport is, as far as I know, the Recommended Way to get correct large 34*4a711beaSLionel Sambucfile support. For more details, see the Large File Support 35*4a711beaSLionel SambucSpecification, published by the Large File Summit, at 36*4a711beaSLionel Sambuc 37*4a711beaSLionel Sambuc http://ftp.sas.com/standards/large.file 38*4a711beaSLionel Sambuc 39*4a711beaSLionel SambucAs a general comment, if you get compilation errors which you think 40*4a711beaSLionel Sambucare related to large file support, try removing the above define from 41*4a711beaSLionel Sambucthe Makefile, ie, delete the line 42*4a711beaSLionel Sambuc 43*4a711beaSLionel Sambuc BIGFILES=-D_FILE_OFFSET_BITS=64 44*4a711beaSLionel Sambuc 45*4a711beaSLionel Sambucfrom the Makefile, and do 'make clean ; make'. This will give you a 46*4a711beaSLionel Sambucversion of bzip2 without large file support, which, for most 47*4a711beaSLionel Sambucapplications, is probably not a problem. 48*4a711beaSLionel Sambuc 49*4a711beaSLionel SambucAlternatively, try some of the platform-specific hints listed below. 50*4a711beaSLionel Sambuc 51*4a711beaSLionel SambucYou can use the spewG.c program to generate huge files to test bzip2's 52*4a711beaSLionel Sambuclarge file support, if you are feeling paranoid. Be aware though that 53*4a711beaSLionel Sambucany compilation problems which affect bzip2 will also affect spewG.c, 54*4a711beaSLionel Sambucalas. 55*4a711beaSLionel Sambuc 56*4a711beaSLionel SambucAIX: I have reports that for large file support, you need to specify 57*4a711beaSLionel Sambuc-D_LARGE_FILES rather than -D_FILE_OFFSET_BITS=64. I have not tested 58*4a711beaSLionel Sambucthis myself. 59
