[Python-Dev] build problems large and small on FreeBSD

[Jeremy Hylton]

I just built the latest CVS sources on a FreeBSD machine (4.1-RELEASE
FreeBSD).  There are a number of compiler warnings, all having to do
with redefinitions, plus some linker warnings and a test failure.

I don't have time to investigate further, but thought I'd let people
know in case someone else has time to take a look.

test_math failed -- overflowing exp() didn't trigger OverflowError

Python 2.0c1 (#2, Oct 13 2000, 15:50:26) 
[GCC 2.95.2 19991024 (release)] on freebsd4
Type "copyright", "credits" or "license" for more information.
>>> import math
>>> math.exp(1200)
Inf

The warnings from the linker seem harmless enough.  I don't know why
it is complaining about setkey and des_setkey.  

/usr/lib/libc.so: WARNING!  setkey(3) not present in the system!
/usr/lib/libc.so: warning: this program uses gets(), which is unsafe.
/usr/lib/libc.so: warning: mktemp() possibly used unsafely; consider using mkstemp()
/usr/lib/libc.so: WARNING!  des_setkey(3) not present in the system!
/usr/lib/libc.so: WARNING!  encrypt(3) not present in the system!
/usr/lib/libc.so: warning: tmpnam() possibly used unsafely; consider using mkstemp()
/usr/lib/libc.so: warning: this program uses f_prealloc(), which is stupid.
/usr/lib/libc.so: WARNING!  des_cipher(3) not present in the system!
/usr/lib/libc.so: warning: tempnam() possibly used unsafely; consider using mkstemp()

The compiler-time warnings look like they are caused by a configure
problem.  If so, I don't know how to fix it :-).
