When I run "FaceTrackingKLTpackNGoExample.m", I get the following error
>> FaceTrackingKLTpackNGoExample
-> Generating Code (it may take a few minutes) ....
??? Build error: Build failed for project 'FaceTrackingKLTpackNGo_kernel'. See the Target Build Log in
the report for further details.
Error in ==> FaceTrackingKLTpackNGo_kernel Line: 1 Column: 1

Error using codegen
Error in FaceTrackingKLTpackNGoExample (line 70)
codegen(codegenArgs{:}, fileName);
When I click "View Error Report", I see the following
/usr/bin/ld: HostLib_rtw.o: undefined reference to symbol 'dlclose@@GLIBC_2.2.5'
/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/libdl.so: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
gmake: *** [/tmp/tp44a3c425_46b9_48ab_b357_fe1e097b3d62/codegen/FaceTrackingKLTpackNGo_kernel] Error 1
Has anyone ever experienced the same problem? Any solution please?

You may need to add the "dl" library to be linked. If you are working from the command line that would be by adding -ldl
I see in the error message a reference to /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/libdl.so . The first .. would take you up to where 4.8 was a child; the second .. would take you up to where x86_64-linux-gnu was a child; the third .. would take you up to where gcc was a child, so that would seem to resolve to /usr/lib/x86_64-linux-gnu/libdl.so . I wonder if that actually exists or if the file is really in /usr/lib/gcc/x86_64-linux-gnu/libdl.so ? Is /usr/lib/gcc/x86_64-linux-gnu/libdl.so perhaps a symlink that resolves to /usr/lib/x86_64-linux-gnu/libdl.so ?

Look in the directory codegenOutDir -- you might have to look a directory down from there to find the Makefile
