[Coin-ipopt] some problems about CUTEr interface

[Zaiwen Wen]

My configuration for Ipopt is:

./configure --with-blas="-L/opt/intel/mkl721/lib/32 -lmkl_lapack 
-lmkl_ia32 -lguide -lpthread" \
  CXXLIBS='-L/usr/lib/gcc/i386-redhat-linux/4.0.2 -lstdc++ -lm -lgcc '
  F77=gfortran

My configuration for CUTEr is:
  CUTEr.large.pc.lnx.g95


I have the following experience:

1. in File /Apps/CUTErInterface/CUTErInterface.f

----------------------------------------
C
C     Call IPOPT
C
       IPROBLEM = IPCREATE(N, X_L, X_U, M, G_L, G_U, NELE_JAC, NELE_HESS,
      1     EV_F, EV_G, EV_GRAD_F, EV_JAC_G, EV_HESS)

---------------------------------------

should be:

--------------------------------------


       IPROBLEM = IPCREATE(N, X_L, X_U, M, G_L, G_U, NELE_JAC, NELE_HESS,
      1   IDX_STY,  EV_F, EV_G, EV_GRAD_F, EV_JAC_G, EV_HESS)

one should also  add definition:
       integer IDX_STY
       parameter  (IDX_STY = 1 )
---------------------------------------

The definition of the function "IPCREATE" is in file:
 	/Interfaces/IpStdFInterface.c


2. According to my experience, if the fortran compiler for ipopt and CUTEr 
are different, there will be some conflictions during compilation when 
using "sdipo\ipo".


3.

Since the new script "ipo" defines
  setenv SYSLIBS "`cat ${MYCUTER}/double/lib/ipo.liblist`", 
it will probably  cause some problems for the following lines in the 
script "runpackage" in "CUTEr/mycuter/bin"

$LOAD $FFLAGS -o ${PAC}min ELFUN.o GROUP.o RANGE.o $EXTER $DRIVER \
       $SUBR $ALT_LIB_PATH -L$LIBDIR $SYSLIBS -lcuter  $BLAS $LAPACK

After these two lines  modifed to:

$LOAD $FFLAGS -o ${PAC}min ELFUN.o GROUP.o RANGE.o $EXTER $DRIVER \
       $SUBR $ALT_LIB_PATH -L$LIBDIR -lcuter  $SYSLIBS

sdipo and ipo work perferctly.



Wish these information will be  helpful.
