Hello
I’m using the Random Forest library for Matlab ( link ). I’m using it for classification. On Windows it works very well out of the box (precombiled mex files) but I also want to run it on a CentOS cluster.
I have tried to compile it on the cluster by executing make mex but I’m getting an error. The output is as follows:
rm twonorm_test -rf
rm tempbuild/*.o *.o -rf
rm *~ -rf
rm *.mexw32 twonorm_test -rf
rm *.mexa64 -rf
rm classRF -rf
rm *.exe -rf
echo 'Compiling classTree.cpp'

Unknown MEX argument '-o'.
make: *** [mex_classRF] Error 255
Does somebody knows how to solve this issue? If you want, you can take RF_MexStandalone-v0.02.zip from the above link and then go to randomforest-matlab/RF_Reg_C/Makefile.

In the corresponding Make file for Windows the mex arguments contain "-output" instead of "-o", so I assume replacing "-o" by "-output" solves the problem.
