Compiling Ruby 1.9.1-p129 on HPUX

Question

I am trying to compile Ruby on HPUX but get the following:

cc: "transcode.c", line 1489: error 1588: "SIZE_MAX" undefined.
cc: "transcode.c", line 1489: error 1563: Expression in if must be scalar.

Answer 1

What HPUX and compiler version?

If I remember correctly SIZE_MAX is only available if you use c99 compiler and include stdint.h (not limits.h).
