Re: Help on installation - Can't find function `int isinf(...)'

[Rodrigo]

Thanks Mats. I tried some ways of doing this without success and I finally 
create a isinf.h and a isinf.c ... Probably not the most elegant way of 
solving it, but it seems to have solved the issue. I successfully built it. 
But now I'm having problems running the program. I will send another post 
related to this new problem.

[]s,

Rodrigo

PS-I'm not sure what I'm supposed to do about the patch you said in your 
email ...
