Hi Stefan:
Here is the output when I try to make the test examples:

Also here are the relevant parts of config_ipopt.h
/* Define to 1 if function drand48 is available */
/* #undef HAVE_DRAND48 */
DRAND48 is not to be found anywhere else in this file.
Is this file rewritten with every configure command or with every make command?
Thanks
Krish

Hi,
> I finally was able to compile Ipopt with the Intel Fortran Compiler (version 11). I then went to config_ipopt.h looking for #define HAVE_DRAND48, but this is not present in the file. I anyway uncommented #undef HAVE_DRAND48 and tried a make tests. But this failed because of unresolved externals drand48 and srand48. I next tried #defien HAVE_DRAND48 0, but this too was of no use. This was not a problem when I first compiled Ipopt with Intel version 10 and MSVC 2005. So I wonder what else I can do to compile the examples and link them with libIpopt.lib. Thanks.
Can you say where the unresolved externals appear, i.e., which file or
function wants to use it?
If there is no #define HAVE_DRAND48 in config_ipopt.h, then Ipopt should
not use it. See Ipopt/src/Common/IpUtils.cpp, from line 140 on.

>> Thanks. I moved the code to another machine that had the Intel Fortran Compiler without MKL. This time around, the BLAS and LAPACK code was compiled and I had no problem creating libipopt.lib. So the issue definitely has something to do with the MKL part of the fortran compiler.
