Hello all this is my first time building GCC, I am able to successfully build GCC but when I run the "make -k check" I get errors. I tried building gcc-5.2.0 first, the tests were failing, so I tired to build gcc-5.1.0 and the check stopped with an Error mid way. I am building on a fresh debain install. $ uname -a Linux karma 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u5 (2015-10-09) x86_64 GNU/Linux $ gcc -v Using built-in specs.
