(Building on HP 9000/300) I'm having problems building write.c from the gas-1.34 distribution on prep.ai.mit.edu. The offending section is md_number_to_chars((char *)&the_exec.a_machtype, EXEC_MACHINE_TYPE, sizeof(the_exec.a_machtype)); What I've fixed so far is the original definition #define EXEC_MACHINE_TYPE HP9000S200_ID which only makes sense when you rewrite as #ifdef hpux #include <magic.h> #define EXEC_MACHINE_TYPE HP9000S200_ID #endif (HP9000S200_ID is defined in HP's include only). Also, there is neither a a_machtype member in GNU a.out.h definition of the exec structure, nor in the a_out.h on the HP. The .o' that result from this do not pass either GNU nm or HP-UX nm. Can anyone offer to post their working write.c etc for HP-UX?

Thanks for your a.out.h file. Now I find that GNU ld.c is not parameterized for different OS and can't read HP a.out.h format. Does anyone have an ld.c for HP-UX, or appropriate diffs?
