Trying to compile GCC 1.34 on HPUX (Version 6.something) fails in
toplev.c seemingly because the macro definitions are too long for the
HPUX compiler. Does anyone have suggestions? patches? sympathy?
In addition to the normal reasons for using GCC, twm (Tom's Window
Manager) for X11 won't compile under the HPUX compiler and we were
hoping gcc would do better.

I had no problem compiling the X11R3 version of twm using the hpux native compiler. The binary from this rev works fine with the hp distributed R2 server.

Does anyone have suggestions? patches? sympathy? I picked up a copy of gcc 1.34 and tried to make it compile on my hp-ux 6.5 system. It died with a syntax error in toplev.c. I narrowed my problem down to the following: 1. toplev.c includes /usr/include/sys/param.h which has the following: #define FLOAT FLOAT_M320 #define FLOAT_M320 5 2. rtl.h includes the following #define DEF_RTL_EXPR(ENUM, NAME, FORMAT) ENUM , 3. rtl.def has a long list of uses of DEF_RTL_EXPR including the following on line 492: DEF_RTL_EXPR(FLOAT, "float", "e") The combination of these three macros causes the preprocessor to create an invalid enum declaration: enum rtx_code { UNKNOWN, NIL, /*etc*/ 5, /*etc*/ } Which the compile complains about. One simple workaround is to get rid of the FLOAT name collision by adding #undef FLOAT after the inclusion of <sys/param.h> in toplev.c. After doing this my copy of gcc 1.34 compiles without complaint.

Until a few weeks ago, (when Tom moved on to Solbourne), twm was being developed on the HP-UX compiler. Mike Stroyan, stroyan@hpfcla.hp.com

Does anyone have suggestions? patches? sympathy? Well, I got GCC 1.34 going on an old HP 9000 Series 200 computer running HP-UX 2.1 (quite different from the 2.1 they had for the 800 series). Our compiler would acctually dump core trying to compile toplev.c (we managed to convince it to pre-process the file no problems, however.) Our solution was to cross compile the compiler on another computer (a VAX running BSD4.3). You probably don't have to go to that extream with your system. Try using GCC's cpp to pre-process toplev.c and pass that code to your normal compiler. If you're only having problems with toplev.c you can make GCC's cpp by entering "make cpp". >In addition to the normal reasons for using GCC, twm (Tom's Window >Manager) for X11 won't compile under the HPUX compiler and we were >hoping gcc would do better. Actually the only thing we ever gave our compiler trouble was GCC itself... Ross Ridge -- l/ attcan!tmsoft!ziebmef!ross // [OO] [oo] -()- -()- db 6502 assembly forever! //

I missed the first part of this discussion but have run into several problems when compiling GNU software. By turning off optimization, the compiles worked. In particular gcc-1.35 and gnu-emacs. I also run X11R3 which I built under HPUX 6.5. -- Boyd Merworth The University of Texas at Austin Department of Computer Sciences, TAY 2.124, Austin, Texas 78712 merworth@cs.utexas.edu {harvard,gatech,uunet}!cs.utexas.edu!merworth
