Hi everyone. I was just looking through the list of ruby modules that don't compile on arm64 and found an interesting problem. For ruby-lapack and ruby-inotify, the rbconfig.rb contains at least one command line argument that's unsupported by gcc-4.8. The rbconfig.rb includes -fstack–protector-strong for CFLAGS and other variables which causes extension compilation to fail: "gcc -o conftest -I/usr/include/aarch64-linux-gnu/ruby-2.1.0 -I/usr/include/ruby-2.1.0/ruby/backward -I/usr/include/ruby-2.1.0 -I. -D_FORTIFY_SOURCE=2 -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -fPIC conftest.c -L. -L/usr/lib/aarch64-linux-gnu -L. -Wl,-z,relro -L/build/ruby2.1-NMeAuY/ruby2.1-2.1.3/debian/lib -fstack-protector -rdynamic -Wl,-export-dynamic -lruby-2.1 -lpthread -lgmp -ldl -lcrypt -lm -lc" gcc: error: unrecognized command line option '-fstack-protector-strong' checked program was: /* begin */ 1: #include "ruby.h" 2: 3: int main(int argc, char **argv) 4: { 5: return 0; 6: } /* end */ I can't think of any good solution to this, short of waiting for the default version of gcc to be updated to 4.9. There doesn't seem to be any way to override anything in rbconfig.rb which would be the obvious fix. )-: Does anyone else have any ideas? It's only a couple of modules so not a huge deal.
