[Gate-users] Workaround for compiling Gate on OS X 10.8 Mountain Lion & 10.7 Lion

[Gaens, Michaela]

Hi Marc and Gate Users,

I actually ran into the same trouble when trying to compile Gate v6.2 on Mac OS X Lion yesterday. In the end I also managed to compile and run Gate, but I went the other way and looked at the code instead of the compiler.

Looking at the definition of std:ostringstream (http://www.cplusplus.com/reference/iostream/ostringstream/ostringstream/), the used constructor in GateUIcmdWithAVector.hh line 124 indeed has the wrong arguments, since it does not expect an integer. After a slight modification the error disappeared.

I then encountered one more error related to GateMaps.hh:

/Applications/gate_v6.2/source/digits_hits/include/GateMaps.hh:120:7: error: use of undeclared identifier 'insert'

It seems that a "this->" was missing there.

After changing that, the compilation completed (using llvm-gcc-4.2) and also the benchmarks worked fine.

I have attached the modified files.

GateUIcmdWithAVector.hh belongs into the folder gate_v6.2/source/general/include and GateMaps.hh into the folder gate_v6.2/source/digit_hits/include .

Maybe someone can have a look if my modifications make sense.
