[Ipopt] Matlab Interface Crash

[Siddharth Goyal]

Hi,

I am trying to install ipopt and use it with matlab. I have used the instructions mentioned on following webpage.
https://projects.coin-or.org/Ipopt/wiki/Ipopt_on_Mac_OS_X

I have used snow leopard,HSL MA 57,native OS X  with 64 bit matlab 2011.
When I run the given examples in ipopt, matlab crashes. I suppose it is because of mex file.
Let me give you more details about the makefile in src folder.

Originally LIBS line in the makefile had 
LIBS = -L/Users/siddharthgoyal/Documents/build/Ipopt-3.10.1/build64/lib -lipopt  -L/Users/siddharthgoyal/Documents/build/Ipopt-3.10.1/build64/lib -lcoinhsl -framework vecLib -L/usr/lib/gcc/i686-apple-darwin10/4.2.1/x86_64 -L/usr/lib/i686-apple-darwin10/4.2.1 -L/usr/lib/gcc/i686-apple-darwin10/4.2.1 -L/usr/lib/gcc/i686-apple-darwin10/4.2.1/../../../i686-apple-darwin10/4.2.1 -L/usr/lib/gcc/i686-apple-darwin10/4.2.1/../../.. -lgfortranbegin -lgfortran -lSystem  -L/Users/siddharthgoyal/Documents/build/Ipopt-3.10.1/build64/lib -lcoinmetis  -framework vecLib -framework vecLib -lm  -ldl

I changed it to 
LIBS = -L/Users/siddharthgoyal/Documents/build/Ipopt-3.10.1/build64/lib -lipopt  -L/Users/siddharthgoyal/Documents/build/Ipopt-3.10.1/build64/lib -lcoinhsl  -L/Users/siddharthgoyal/Documents/build/Ipopt-3.10.1/build64/lib -lcoinmetis -lm  -ldl


when I make the file, the result on the terminal is 

-> mexopts.sh sourced from directory (DIR = $PREF_DIR)

Please let me know if this is a successful compilation. If yes, why does the matlab crash. If not, how can it be fixed.


Thanks
