QT 4.2.3 Compilation error on solaris10 (sparc)

[Intaek Lim]

Hello, I need to compile QT 4.2.3 on solaris 10 (sparc).
But, when I make the project, there's an error on src/corelib as follows

____________

cc1plus: error: invalid option 't'

I cannot figure out what the option 't' means. Any suggestion?

thanks in advance.

An option "t" is given to the compiler, and this option is not recognized.
I remember getting this error when compiling Qt 3.x on Solaris x86 with Sun Studio, some time ago. I solved the problem by switching to gcc. If you have this possibility, maybe you should consider doing it.

Yeah, I know that... but,, the same error occurs even though using gcc instead of g++.

Thanks anyway.

Now, I omitted the option '-mt' (CXXFLAGS in src/corelib/Makefile and src/gui/Makefile) and everything seed to be fine. But, I'm not sure really it is. What the option '-mt' means to gcc(or g++)?
