We ship a full MinGW environment + dependencies in order to compile OpenModelica. It possibly works with MinGW 4.7, but I believe it is a whole lot to change for not much gain (gcc 4.7 is much slower than gcc 4.4).

Hello sjoelund.se

Thank you for the advice.

I am trying to do it because in the model I use C libraries that have to be compiled without optimizations If I try to add any optimization to the minimum file with the simplest math operations, I get strange results.

However this happened to me some versions ago. I will try it again to see if the problem with the supplied compiler is solved.

Thank you!

Hello sjoelund.se

I have tried to use gcc-mingw optimizations (-O3) and now they work perfectly with the compiler supplied.

I will try to compile OMC. However now it is not so important

Best regards
