Two instances of g++ delivered with Qt?

[mzimmers]

Hi -

I just noticed that Creator is finding two instances of g++:

• QtSDK\mingw\bin\mingw32-g++.exe
• QtSDK\mingw\bin\g++.exe

did it come this way? I just downloaded the "standard" version of Qt (didn't build it myself or anything).

do I need both versions? (I like to keep things minimal)

if I don't need both, what's the safe way to delete one of them?

Thanks.

Hi,

Answer from "mingw faq":http://www.mingw.org/wiki/FAQ exaplains that quite well.

What's the difference between gcc and mingw32-gcc?
The mingw32-gcc, mingw32-g++, etc. binaries exist as an aid to cross development. They are created in a typical build of gcc. They are therefore distributed as the maintainers of GCC meant them to be. The gcc.exe indicates that the binary produces binaries for a target equal to the build, while the mingw32-gcc binary produces binaries to be executed on the mingw32 target.

I need to return to this question, though it's been a few months.

If I understand the explanation, when I'm using Qt to build an app for the same platform from which I'm running Qt, I want gcc.exe (or, presumably, g++.exe).

If this assumption is correct, how do I tell my project that I want to choose g++.exe over mingw32-g++.exe? I suspect this is causing me some compile issues.

Does the solution entail using the QMAKE_CXX variable in my .pro file?

Thank you.
