Building libruby-static.a with option nodynamic and --with-static-link-ext doesn't disable dlopen
I uncomment option nodynamic in ext/Setup and run ./configure --with-static-link-ext, then make libruby-static.a
I then compile this:
/* trial.c */
gcc -c trial.c -o trial.o -Iruby-1.9.2-p180/include -Iruby-1.9.2-p180/.ext/include/i686-linux
gcc -static trial.o -Lruby-1.9.2-p180 -lruby-static -lpthread -lrt -ldl -lcrypt -lm -o trial
And I see this warning:
ruby-1.9.2-p180/libruby-static.a(dln.o): In function `dln_load':
/home/alex/projects/scratch/ruby/ruby-1.9.2-p180/dln.c:1276: warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
I specifically do not want any run-time code loading capability, but I can see no documented way to disable dlopen; is there any way to silence this warning?
