Hi, I want to install gcc 4.9 in Ubuntu in ARMv7 multicore processor. The cores are of type Cortex-A7. I tried to add toolchain repository with sudo add-apt-repository ppa:ubuntu-toolchain-r/test but failed. I then tried to make from gcc 4.9.2 branch. But got the following error. In file included from ./bconfig.h:3:0, from ../../gcc-4.9.2/gcc/genmddeps.c:18: ./auto-host.h:2056:16: error: declaration does not declare anything [-fpermissive] #define rlim_t long ^ Could you help. I prefer precompiled binaries.
