Re: gcc 7.2.0 failed with cstdlib:75:15: fatal error: stdlib.h: No such file or directory on a hello-world program
OK. Never mind. I figure it out. The problem lies in the specs file I created
using brew postinstall gcc, where the line:
*cpp_unique_options:
+ -isystem /home/linuxbrew/.linuxbrew/include
makes searching for stdlib.h in /scratch/.linuxbrew/include impossible for
system header like cmath. This is a known issue:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70129
Either removing that or change it to -I /home/linuxbrew/.linuxbrew/include
solves the problem.
