[ros-users] Errors compiling gmapping

OSX 10.7.2
XCode 4.3.2

I found a strange error in gmapping under build/gmapping_export/gridfastslam/gfs2rec.cpp, for some reason i gets redefined (line 148)? 

struct ResampleRecord: public Record{
	vector<unsigned int> indexes;
	virtual void read(istream& is){
		is >> dim;
		for (unsigned int i=0; i< dim; i++){
			unsigned int i; <<<<<<< why redefined???
			is >> i;

Unfortunately all of this code appears to be in a tar ball so when I fix the code and do a make clean, it all gets erased and downloaded again. 

I tried not doing the make clean, but it still fails because the makefile tries to reapply patches to code it already applied patches too. I commented out the code in cmakelists.txt so it can move on (it failed because of the failed patch re-applies), but then the next errors are the paths are not setup correctly.

This code is hosed … I assume it runs on Linux right? How can I fix the include path?
