I have a problem with gthr-default. I'm using dev c++. Any time I do something in it I get these errors:

C:\Program Files (x86)\Dev-Cpp\MinGW64\lib\gcc\x86_64-w64-mingw32\4.9.2\include\c++\x86_64-w64-mingw32\bits\gthr-default.h In function 'int __gthread_create(__gthread_t*, void* ()(void), void*)':

C:\Program Files (x86)\Dev-Cpp\MinGW64\lib\gcc\x86_64-w64-mingw32\4.9.2\include\c++\x86_64-w64-mingw32\bits\gthr-default.h [Error] 'NULL' was not declared in this scope

Anyone know what to do?

Can you pose your code? At least minimal reproducer – P. Dmitry
You shouldn't include gthr-default.h in your own code, ever. – rubenvb

NULL defined in stdef. Try to add #include <cstddef> before gthr-default.h include.
