gcc problems in MDK 9.0
 

I can't compile progs from tar.gz files.
When I wanted to compile Kvirc I get error message
error:

checking for g++... no
checking for gcc... no
checking for CC... no
checking for cxx... no
checking for cc++... no
checking for cl... no
checking whether the C++ compiler (gcc -O2 ) works... no
configure: error: installation or configuration problem: C++ compiler cannot create executables.

When I wanted to compile GNU-Gadu I ger error:
checking for gcc... no
checking for cc... no
checking for cc... no
checking for cl... no
configure: error: no acceptable C compiler found in $PATH

When I was using MDK 8.2 I haven't such problems. How to fix this in MDK 9.0?
