 Dear Andreas,

 I installed successfully Ipopt with linking WSMP (trial version) by using
 the following configuration,

 ./configure AR='ar -X64' NM='nm -X64' CC='xlc_r -q64' F77='xlf_r -q64'
 CXX='xlC_r -q64' CFLAGS='-O3 -qarch=auto -qcache=auto -qhot -qtune=auto
 -bmaxdata:0x7f0000000' FFLAGS='-O3 -qarch=auto -qcache=auto -qhot
 -qtune=auto -bmaxdata:0x7f0000000' CXXFLAGS='-qrtti=dyna -O -qarch=auto
 -qcache=auto -qtune=auto -bmaxdata:0x7f0000000' --with-blas="-lm_r
 -lessl_r -qsmp=omp" --with-wsmp="/home/andanh/wsmp-AIX/lib/libwsmp64.a
 -q64 -b64 -lpthread -lm_r" --disable-shared

 Here is my .profile :

 I was able to solve the example hs071_f and other small problems. However
 when I executed a big problem on our server (AIX 5.0, 6.9Gb, 4 processors)
 , Ipopt is terminated after the first step.

 Here is abstract of IPOPT.OUT

 Start reading options from stream.
 Adding option "tol" with value "1.e-4" to OptionsList.
 Adding option "linear_solver" with value "wsmp" to OptionsList.
 Adding option "wsmp_num_threads" with value "4" to OptionsList.
 Adding option "max_iter" with value "5000" to OptionsList.
 Finished reading options from file.

 Could you give me advice how to fix this?

 Thank you in advance.
