[SciPy-dev] undefined symbols in scipy_core-0.4.2

[Lisandro Dalcin]

If this has been reported, please ignore it...

I've got undefined symbols in  scipy/lib/lapack_lite.so:

[dalcinl at trantor lib.linux-i686-2.4]$ python
Python 2.4.2 (#1, Sep 28 2005, 15:28:55)
[GCC 3.3.3 20040412 (Red Hat Linux 3.3.3-7)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from scipy.base import *
Traceback (most recent call last):

  File "scipy/basic/basic_lite.py", line 7, in ?
    import scipy.lib.lapack_lite as lapack_lite
ImportError: scipy/lib/lapack_lite.so: undefined symbol: s_cat

Googling, I've found this reference about 'libg2c':

http://gcc.gnu.org/ml/gcc-help/2000-12/msg00010.html

I added  '-lg2c' flag (manually, in the command line, and it worked!). Perhaps

Sorry if I can't help a bit more right now! I am a recent user
(comming from numarray) and I have not found the time to look at
scipy.distutils.


BTW, I got the following warnings...
