If you get failures in test_long, or sys.maxint gets set to -1, you

are probably experiencing compiler bugs, usually related to

optimization. This is a common problem with some versions of gcc and

egcs, and some vendor-supplied compilers, which can sometimes be
|

worked around by turning off optimization. Consider switching to

stable versions (gcc 2.7.2.3, egcs 1.1.2, or contact your vendor.)

From Python 2.0 onward, all Python C code is ANSI C. Compiling using

old K&R-C-only compilers is no longer possible. ANSI C compilers are

available for all modern systems, either in the form of updated

compilers from the vendor, or one of the free compilers (gcc, egcs).

When the dynamic loader complains about errors finding shared

libraries, such as

|

ld.so.1: ./python: fatal: libstdc++.so.5: open failed:
|

No such file or directory
|

|

you need to first make sure that the library is available on
|
||||
your system. Then, you need to instruct the dynamic loader how
|
||||
to find it. You can chose any of the following strategies:
|
||||
|
||||
1. When compiling Python, set LD_RUN_PATH to the directories
|
||||
containing missing libraries.
|
||||
2. When running Python, set LD_LIBRARY_PATH to these directories.
|
||||
3. Use crle(8) to extend the search path of the loader.
|
||||
4. Modify the installed GCC specs file, adding -R options into the
|

*link: section.
