Thanks again, Peter. I did as you suggested and the result works pretty well. Prompted by the diagnostic from gdb/utils.c, I also added MMALLOC_CFLAGS = -I$(MMALLOC_SRC) -DMMCHECK_FORCE=1 in i386sol2.mh. The only thing that's a little odd is that now I get this at startup: [GDB will not be able to debug user-mode threads: ld.so.1: gdb: fatal: relocation error: symbol not found: ps_lgetLDT: referenced in /usr/lib/libthread_db.so.1] and this when I `quit': (gdb) q gdb internal error: Memory corruption Quit [Exit 131 (SIGQUIT)] "Peter.Schauer" <Peter.Schauer@Regent.E-Technik.TU-Muenchen.DE> writes: | GDB is not supported on ix86/solaris, and I do not have access | to a ix86/solaris system, so I can't comment on the first two patches. | (I suspect however that a better solution would be to create a new | config/i386/tm-i386sol2.h file, which gets used by i386sol2.mt, includes | tm-i386v4.h and adds the TIDGET definition from config/sparc/tm-sun4sol2.h). | | The linker problem happens if you use gcc and the native ld. | A simple workaround for now is to remove | -Xlinker -export-dynamic | by hand from the INTERNAL_LDFLAGS in gdb/Makefile. | | > Hi, | > | > I have the misfortune to run solaris2.5.1 on my nice dual P200 Vectra. | > I tried to build gdb-970817 using this version of egcs: | > | > Reading specs from /p/lib/gcc-lib/i386-pc-solaris2.5.1/egcs-2.90.06/specs | > gcc version egcs-2.90.06 970907 (gcc2-970802 experimental) | > | > My first compile failed because neither R_PSR nor PS_FLAG_CARRY was defined. | > Here's a kludge to work around that. | > | > --- procfs.c.orig Sat Sep 27 12:22:02 1997 | > +++ procfs.c Sat Sep 27 12:21:50 1997 | > @@ -5218,6 +5218,7 @@ procfs_lwp_creation_handler (pi, syscall | > /* If lwp_create failed, then nothing interesting happened.
