bzip2-1.0.4 should compile without problems on the vast majority of
|
|
platforms. 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.
