I use some library which use boost in my project. I am not familiar with c++ and boost. Compilation of my project shows me the next:

I cannot identify really if it is a problem of the boost, or the libraries which I use or...

Who can comment these errors?

It sounds like G is defined as a macro. Whatever code is doing this is wrong. It is certainly not Boost. You can check this with #ifdef G #error Oops, G is a macro #endif In Christ, Steven Watanabe
