-Python for AtheOS
-
-
-Before building:
-
- Make sure you have shared versions of the libraries you want to use
- with Python. You will have to compile them yourself, or download
- precompiled packages.
-
- Recommended libraries:
-
- ncurses-4.2
- readline-4.2a
- zlib-1.1.4
-
-Build:
-
- $ ./configure --prefix=/usr/python
- $ make
-
- Python is always built as a shared library, otherwise dynamic loading
- would not work.
-
-Testing:
-
- $ make test
-
-Install:
-
- # make install
- # pkgmanager -a /usr/python
-
-
-AtheOS issues:
-
- - large file support: due to a stdio bug in glibc/libio, access to
- large files may not work correctly.
- fseeko() tries to seek to a negative offset.
- ftello() returns a negative offset, it looks like a 32->64bit
- sign-extension issue.
- The lowlevel functions (open, lseek, etc) are OK.
- - sockets: AF_UNIX is defined in the C library and in Python, but
- not implemented in the system.
- - select: poll is available in the C library, but does not work
- (It does not return POLLNVAL for bad fds and hangs).
- - posix: statvfs and fstatvfs always return ENOSYS.
- -
- - disabled modules:
- - mmap: not yet implemented in AtheOS
- - nis: broken (on an unconfigured system yp_get_default_domain()
- returns junk instead of error)
- - dl: dynamic loading doesn't work via dlopen()
- - resource: getrimit and setrlimit are not yet implemented
-
- - if you are getting segmentation faults, you probably are low on memory.
- AtheOS doesn't handle very well an out-of-memory condition and
- simply SEGVs the process.
-
-Tested on:
-
- AtheOS-0.3.7
- gcc-2.95
- binutils-2.10
- make-3.78
