Re: Building gtk+ is a pain on HP-UX, Tru64, IRIX

Dear Owen,

Thanks for the replies.

HP-UX 11 isn't supported on the 9000/720 hardware I have.

(Of course this begs the question, why does anybody want to use
 a ten-year old computer anyway.  It never crashes.)

Hmm, apparently something was fixed in gtk+ between 2.0.2 and 2.0.5 and
now it builds cleanly on IRIX 6.5 using gcc 3.0.3.  Attempting with the
MIPSpro kit, several warnings are presented while compiling gtkentry.c
and the compiler dumps core:

(there were maybe 20 warnings altogether, most of them 1185 (An
enumerated type is mixed with another type.))

Back to HP-UX 10.20 and HP ANSI C:

I compiled glib 2.0.1 with gcc, so it is defined in the glibconfig.h
that I was then using to compile gtk+, which explains this.

The reason for doing that was apparently that the glib configure was
unable to find a 64 bit type using the HP compiler.  The default
CFLAGS it uses are -Aa (strict ANSI mode).

I found that -Ae (extended ANSI mode) would enable long long, and
pre-setting CPPFLAGS and CFLAGS to "-Ae" got rid of this problem
and allowed building glib with HP ANSI C.

Also, there were some GDK X11 related problems when compiling gtk.
They seemed to go away if the /usr/include/X11R6 directory is
explicitly included.  (HP-UX 10.20 default X includes are R4.
R5 and R6 stuff are present but have to be explicitly mentioned.)

(Well, I thought I was reporting them by sending them to the developers
 list.  Also, having to go to the hassle of creating endless user
 accounts at sites one might use once every year seems just a bit
 pointless to me.)

No, it's glib 2.0.1.  I'll upgrade and retry, and I'll also take note
of the libiconv issues you mentioned.
