15 bzip2-1.0.6 should compile without problems on the vast majority of | |
16 platforms. Using the supplied Makefile, I've built and tested it | |
17 myself for x86-linux and amd64-linux. With makefile.msc, Visual C++ | |
18 6.0 and nmake, you can build a native Win32 version too. Large file | |
19 support seems to work correctly on at least on amd64-linux. | |
20 | |
21 When I say "large file" I mean a file of size 2,147,483,648 (2^31) | |
22 bytes or above. Many older OSs can't handle files above this size, | |
23 but many newer ones can. Large files are pretty huge -- most files | |
24 you'll encounter are not Large Files. | |
25 | |
26 Early versions of bzip2 (0.1, 0.9.0, 0.9.5) compiled on a wide variety | |
27 of platforms without difficulty, and I hope this version will continue | |
28 in that tradition. However, in order to support large files, I've had | |
29 to include the define -D_FILE_OFFSET_BITS=64 in the Makefile. This | |
30 can cause problems. | |
31 | |
32 The technique of adding -D_FILE_OFFSET_BITS=64 to get large file | |
33 support is, as far as I know, the Recommended Way to get correct large | |
34 file support. For more details, see the Large File Support | |
35 Specification, published by the Large File Summit, at | |
36 | |
37 http://ftp.sas.com/standards/large.file | |
38 | |
39 As a general comment, if you get compilation errors which you think | |
40 are related to large file support, try removing the above define from | |
41 the Makefile, ie, delete the line | |
42 | |
43 BIGFILES=-D_FILE_OFFSET_BITS=64 | |
44 | |
45 from the Makefile, and do 'make clean ; make'. This will give you a | |
46 version of bzip2 without large file support, which, for most | |
47 applications, is probably not a problem. | |
48 | |
49 Alternatively, try some of the platform-specific hints listed below. | |
50 | |
51 You can use the spewG.c program to generate huge files to test bzip2's | |
52 large file support, if you are feeling paranoid. Be aware though that | |
53 any compilation problems which affect bzip2 will also affect spewG.c, | |
54 alas. | |
55 | |
56 AIX: I have reports that for large file support, you need to specify | |
57 -D_LARGE_FILES rather than -D_FILE_OFFSET_BITS=64. I have not tested | |
58 this myself. |
