Filip Navara :
My rough guess is that it's combination of wrong include path (in ROS build files) and non-PCH compiler (ie. GCC < 3.4).
Maybe, yes, thanks, but I used latest (2 month ago) mingw-gcc 3.4.x (now I'm writing from other computer, at work, and not remember third version digit, sorry). Filip, what did you mean under "ROS build files"? *.c sources from my messages? If yes - it will be Perhaps, better, to correct sources as I wrote to provide compilation not only under PCH compilers?
