The old solution of sticking “#define inline” in config.h did not work, though. Any ideas? BTW, you can get access to HP-UX (and OpenVMS, Linux, Windows 2003 Server and FreeBSD 6.2) via the HP testdrive program at [http://www.testdrive.hp.com](http://www.testdrive.hp.com) (which is what I’m using in an attempt to get some platform info for rubygems).

If I rememeber correctly from my own attempts to build Ruby on HP-UX, one of the issues is that HP’s make is broken and incorrectly thinks parse.y is out of date, trying to regenerate it with HP’s yacc, which is also broken. Things generally get much better if you use the GNU toolchain (make, bison, gcc) rather than HP’s. But note that you’ll still need to disable IPv6 support or else the socket library won’t actually work (because HP’s IPv6 support is broken). Also, make sure that the linker patches are up-to-date, or you may run into linker issues down the road. -mental ---

The only other quirks I noticed is that you have to run make twice - the first one fails, but then the second works - and that ext/curses may cause the build to fail. I simply removed ext/curses altogether, but I think older posts have better soltuions. Regards, Dan ---

I am guessing that cc doesn’t integrate directoy with yacc/flex/bison/ etc. parse.y isn’t C code. ---

There’s definitely something odd going on, but I managed to build and install gperf, which solved it. > Things generally get much better if you use the GNU toolchain (make, > bison, gcc) rather than HP’s.

Yes, I can’t say I’m too impressed with the HP-UX libraries or toolchain. Unfortunately, we do have a couple of HP-UX machines at work, so I still like to support it when I can. > Also, make sure that the linker patches are up-to-date, or you may > run into linker issues down the road. I hit one already trying to build zlib. ☹ Thanks, Dan
