Package: coinor-libipopt-dev
Version: 3.8.3-2
Severity: normal
I have been using a hand-compiled libipopt with a C++ program
for a while. The linear solver for ipopt was ma27 (fortran). The
C++ program was purely sequential, hence there was no need
to mention or have MPI.
Now I want to build the same program with libipopt from the new
package (thanks for packaging, by the way!). As the linker flags
I use
-lipopt -llapack -lblas -lgfortran
which is what worked before. (As ma27 is not used anymore I guess
the -lgfortran is obsolete.) The program compiles and links,
however when running it I get
symbol lookup error: /usr/lib/libipopt.so.0: undefined symbol: MPI_Init
on the first call to libipopt, and the program aborts.
Trying to be smart, I add -lmpi to me list of linker flags. Then I
get the run time error
[haile:4637] *** An error occurred in MPI_Comm_rank
[haile:4637] *** on communicator MPI_COMM_WORLD
[haile:4637] *** MPI_ERR_COMM: invalid communicator
[haile:4637] *** MPI_ERRORS_ARE_FATAL (your MPI job will now abort)
Is this a bug or am I using the wrong flags? How can I find out what
the correct linker flags are? The ipopt manual mentions a file
ipopt_addlibs_cpp.txt with this information, but it is not contained
in the Debian package.
I guess the most elegant solution would be to use pkg-config.
Support for pkg-config seems to have entered the ipopt code
shortly after the 3.8.3 release. Maybe it can be backported?
