Build error Python 2.4.1 - stat problem?

[Guest]

Hello,

I tried to build Python 2.4.1 on a Reliant Unix system. Just after the
python executable program has been built, I get the following error:

==== begin make output ===
CC -W1 -Blargedynsym -o python \
Modules/python.o \

==== end make output ===

It is strange that the Makefile complains about /usr/local/lib/python2.4
since this is still the build phase, far away from the installation into
/usr/local.


I used the python executable from the build directory to run the
following program:

import os

def main():
if not (os.path.exists("/")):
print "/ does not exist"
else:
print "/ exists"
if not (os.path.isdir("/")):
print "/ is not a directory"
else:
print "/ ok"

if __name__ == "__main__":
main()

The output is:

/ exists
/ is not a directory

It's the same for every (existing) directory name I try: os.path.isdir()
always returns false.

It looks as if the stat results are not recognised: os.path.exists()
works, but all the functions os.path.isdir(), os.path.isfile() etc.
don't.

Could anyone help me to solve the problem?

Unless there are other Reliant users here ahead of you, some
of it is going to be up to you. If you follow isdir() back,
you'll find some hard-coded octal bitmask definitions, including
S_IFDIR = 0040000.

Check it out. Try to use that value the way they're using it,
in C and in Python, and print out all the values involved.
At worst, if C comes out wrong too, you may have a question
that the vendor will be more likely to respond to.
