gdb 4.18 on Solaris 7 x86?

[Petr Ovchenkov <ptr@paragraph.ru>]

Is anybody made 4.18 working under Solaris 7 x86?

I made changes in gdb/procfs.c so no more
"Inappropriate ioctl for device" happens, and correct permittions for
/proc/XXXX/crt. But still can't set any breakpoint (indeed can,
but gdb don't stop on it).

Reading specs from /usr/local/lib/gcc-lib/i386-pc-solaris2.7/2.95/specs
gcc version 2.95 19990728 (release)


Result same for C and C++.

When gdb say "/proc/11504/ctl: No such file or directory.", process

Can any help?

If somebody interesting by /proc/... workaround for Solaris 7,
patch for available.
