Config mex for Matlab on macOS

July 7, 2012 Leave a comment

I have been trying a lot to make the ‘mex’ working on my mac. But a lot of errors such as can’t find the ‘float.h’, although it is there! multiple tries… finally fix this problem today 🙂

I searched a little bit and finally found this link is quite useful. Basically, you have to make some changes of the ‘’ file. I have Matlab 2012a, and x-code 4 installed. I didn’t try the suggestion of downloading Xcode3, but the following suggestions work. Find the block of ;; maci64, and change MACOSX_DEPLOYMENT_TARGET to ‘10.6’. Also remove -isysroot in CFLAGS and CXXFLAGS (there are two -isysroot).  Here’s my final file.

 CFLAGS="-fno-common -no-cpp-precomp -arch $ARCHS -mmacosx-version-min=$MACOSX_DEPLOYMENT_TARGET" 
 CFLAGS="$CFLAGS -fexceptions"
 CLIBS="$CLIBS -lstdc++"
 CXXFLAGS="-fno-common -no-cpp-precomp -fexceptions -arch $ARCHS -mmacosx-version-min=$MACOSX_DEPLOYMENT_TARGET" 
 CXXLIBS="$MLIBS -lstdc++"

3D Reconstruction (I)

Today’s my first test on Bundler
I didn’t use the source cause there are many packages needed to be set up first, so I follow the recommendation using the binary package (
There are some error I encountered cause I carelessly NOT copying the into the the required path. Well this can be easily fixed by changing/adding the dir-path of to your LD_LIBRARY_PATH. In my case, the LD_LIBRARY_PATH is empty, so I simply create this env-variable.

export LD_LIBRARY_PATH=./bin/

This should be the directory path to the, otherwise you will get error that ‘error while loading shared libraries: cannot open shared object file: No such file or directory’.

So read carefully for the ‘Before you begin’ section. Also, if you are trying older version, e.g. v0.2, you will need to change the BASE_PATH for multiple files, such as the sift.txt. Just check if there is BASE_PATH for your ‘TO-DO’.

Find my gtk version on ubuntu
$ dpkg -s libgtk2.0-0|grep ‘^Version’
