GCC 4.6

GCC 8.0

And what about your GNU toolchain?

$ gcc -v

[Lucretia]

gcc 6.4.0

Ahh my tree.h doesn't have it.

Please install dependence at first https://github.com/xiangzhai/dragonegg/wiki/Dependence take my LinuxBox Fedora 25 for an instance:

$ grep debug_tree -r /usr/lib/gcc/x86_64-redhat-linux/6.4.1/plugin/include/
/usr/lib/gcc/x86_64-redhat-linux/6.4.1/plugin/include/print-tree.h:extern void debug_tree (tree);

I have the corect files in the right place, but no matter what I do it cannot find them. It keeps trying to the find the system compiler's versions.
