[Ipopt] compilation of 3.7.0 failed

[Dieter Kraft]

Hi,

has anybody been successful to compile ipopt 3.7.0
with Fedora 11 and gcc 4.4.0?

I get:

configure: Configuration of Ipopt successful
configure: Main configuration of Ipopt successful
root at dk/usr/local/Ipopt> make

if I exclude the definition of log2 in
/usr/include/bits/mathcalls.h:145: note: previous declaration of '__log2'
everything works. But is this allowed for the compilation of other software?

Thanks
Dieter
