I tried to install smatch but I'm getting some errors: First I did : git clone git://repo.or.cz/smatch.git Then : cd smatch When I run : make .. I get the following error Makefile:107: Your system does not have libgtk2, disabling test-inspect LINK sparse-llvm /usr/bin/ld: cannot find -ledit collect2: error: ld returned 1 exit status Makefile:211: recipe for target 'sparse-llvm' failed make: *** [sparse-llvm] Error 1 So I tried to install : sudo apt-get install libgtk2.0-dev which gives the error: Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libgtk2.0-dev : Depends: libglib2.0-dev (>= 2.27.3) but it is not going to be installed Depends: libgdk-pixbuf2.0-dev (>= 2.21.0) but it is not going to be installed Depends: libpango1.0-dev (>= 1.20) but it is not going to be installed Depends: libatk1.0-dev (>= 1.29.2) but it is not going to be installed Depends: libcairo2-dev (>= 1.6.4-6.1) but it is not going to be installed E: Unable to correct problems, you have held broken packages. Any help? Thanks in advance :)
