This part looks good to me, but I think the part that follows
should be wrapped in a LDFLAGS="..." block, like this:<br>
<br>
LDFLAGS="-L/Users/ray/build/Ipopt-3.10.1/build/lib -lipopt
-L/Users/ray/build/Ipopt-3.10.1/build/lib -lcoinmumps -lpthread

-lgfortran -lSystem -L/Users/ray/build/Ipopt-3.10.1/build/lib
-lcoinmetis -framework vecLib -framework vecLib -framework vecLib
-lm -ldl"<br>
<br>
And then the remainder looks fine to me:<br>
<br>
-output ipopt.mexmaci64 matlabexception.o matlabfunctionhandle.o
matlabjournal.o iterate.o ipoptoptions.o options.o sparsematrix.o
callbackfunctions.o matlabinfo.o matlabprogram.o ipopt.o</font><br>
<br>
The "-framework vecLib" statement appears multiple times because the
library dependencies are generated automatically by pkgconfig, and
may contain repetitions. I hope something I said is helpful!<br>
