[Ipopt] Problem running Ipopt matlab interface

Hi again. From your original email, it looks like you modified the makefile 
for the Matlab interface a fair amount relative to what configure generated? 
The line that appears to be causing a problem is
> -L/usr/site-local/lib/gcc/x86_64-unknown-linux-gnu/4.2.4 -lgfortran

This is leading mex to link against the 4.2.4 version of libgfortran, rather 
than the 4.6 version that you compiled BLAS, LAPACK, and the HSL routines 
with. I'm guessing that if gfortran-4.6 is in /usr/bin, then the libgfortran 
that you want to link against is probably in 
/usr/lib/gcc/x86_64-unknown-linux-gnu/4.6.something (possibly with the 
2nd-to-last folder named more specific depending on your distro), or maybe 
just in /usr/lib[64].

Usually pkg-config figures this all out for you and automatically links to 
the right libraries. Was that method not working?

-Tony

Subject: Re: [Ipopt] Problem running Ipopt matlab interface

Thanks for the answers. I built a static version of ipopt. But now I
get an error when compiling the Matlabinterface:

This was my configure call for compiling ipopt:
../configure --prefix=/homes/numerik/paul/lib/Ipopt \
CXX=/usr/site-local/bin/g++-4.2 \
CC=/usr/site-local/bin/gcc-4.2 \
F77=/usr/bin/gfortran-4.6 \
ADD_CXXFLAGS="-fPIC -fexceptions -DFUNNY_LAPACK_FINT" \
ADD_CFLAGS="-fPIC -fexceptions" \
ADD_FFLAGS="-fPIC -fexceptions" \
--with-matlab-home=/net/matlab/Matlab2011b \
LDFLAGS="-L/usr/lib64 -lblas_pic" \
-disable-shared

Ipopt compiled fine, but when I try to compile the matlab interface I
get an error:
