Do you not include any ruby headers in your code ? If you do, you should make
sure to pick those matching the library you are using. It might well work
without, but that will be just by pure chance..
Just this:
#include <ruby/ruby.h>
If I use the "-I" flag, like so:
gcc -Wall -v -o run run.c -L/opt/local/lib -lruby.2.1
-I/opt/local/include/ruby-2.1.0/ -I/opt/local/include/ruby-2.1.0/
then it fails to compile, with this error:
#include <...> search starts here:
/opt/local/include/ruby-2.1.0
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/5.1/include

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks
(framework directory)
End of search list.
In file included from run.c:1:
/opt/local/include/ruby-2.1.0/ruby/ruby.h:24:10: fatal error:
'ruby/config.h'
file not found
#include "ruby/config.h"
^
Ruby seems to have a convoluted batch of headers; multiple versions of
"ruby.h" are located in the tree for reasons unknown to me. I've seen
this error before when trying to compile against MacPorts Ruby and
trying to guess at the include path.
Any suggestions, especially when the other invocation works as expected?
