Hi,all
I referred to Martin's method in " Walkthrough: Installation of OpenFOAM-1.6-ext on openSUSE 12.2 64-bit", there is a question about how to do a hotfix through git. As he says:
# apply the hotfix for gcc4.7 by Philippose Rajan
git branch hotfix/gcc47
git checkout hotfix/gcc47

I just don't know how to do it . So this time I ignored this problem and went on. The ThirdParty was installed with no error. While in the Allmake stage when compiling OpenFOAM-1.6-ext, some errors occured:

r/lib64/gcc/x86_64-suse-linux/4.7/../../../../x86_64-suse-linux/bin/ld: cannot find -ldynamicMesh
/usr/lib64/gcc/x86_64-suse-linux/4.7/../../../../x86_64-suse-linux/bin/ld: cannot find -lmeshTools
collect2: error: ld returned 1 exit status
make: *** [/home/huangxian/OpenFOAM/OpenFOAM-1.6-ext/lib/linux64Gcc47DPOpt/libfaceDecompositionMotionSolver.so] Error 1

and

Many similar errors as above. I suppose the reason is the previous step hotfix of Gcc47 undo. Can anybody give me some advise to git a hotfix as the author says?
