Using the supplied Makefile, I've built and tested it +myself for x86-linux and amd64-linux. With makefile.msc, Visual C++ +6.0 and nmake, you can build a native Win32 version too. Large file +support seems to work correctly on at least on amd64-linux. + +When I say "large file" I mean a file of size 2,147,483,648 (2^31) +bytes or above. Many older OSs can't handle files above this size, +but many newer ones can. Large files are pretty huge -- most files +you'll encounter are not Large Files. + +Early versions of bzip2 (0.1, 0.9.0, 0.9.5) compiled on a wide variety +of platforms without difficulty, and I hope this version will continue +in that tradition. However, in order to support large files, I've had +to include the define -D_FILE_OFFSET_BITS=64 in the Makefile. This +can cause problems. + +The technique of adding -D_FILE_OFFSET_BITS=64 to get large file +support is, as far as I know, the Recommended Way to get correct large +file support. For more details, see the Large File Support +Specification, published by the Large File Summit, at + + http://ftp.sas.com/standards/large.file + +As a general comment, if you get compilation errors which you think +are related to large file support, try removing the above define from +the Makefile, ie, delete the line + + BIGFILES=-D_FILE_OFFSET_BITS=64 + +from the Makefile, and do 'make clean ; make'. This will give you a +version of bzip2 without large file support, which, for most +applications, is probably not a problem. + +Alternatively, try some of the platform-specific hints listed below. + +You can use the spewG.c program to generate huge files to test bzip2's +large file support, if you are feeling paranoid. Be aware though that +any compilation problems which affect bzip2 will also affect spewG.c, +alas. + +AIX: I have reports that for large file support, you need to specify +-D_LARGE_FILES rather than -D_FILE_OFFSET_BITS=64. I have not tested +this myself. |
