Install Problem etc/linux.c UBUNTU Hardy Heron and gcc 4.2.4
drandy...@googlemail.com
excuse my ignorance, but I've followed the instructions on installing
lcc on linux for x86 and I am having a few problems. Everything
compiles, but it fails on
lcc -v tst/8q.c
(Added #include <stdio.h> to 8q.c).
The etc/linux.c does not seem to be working correctly for my setup. If
anyone has successfully installed lcc on a UBUNTU or a debian
distribution then I would welcome being able to download their
source. I'm intending to use it for teaching a compiler course. By
changing the cpp options on the last line to "$1", "$2", "-o", "$3",
0 }; I can get the assembler produced (output listed as ALTERED etc/
linux.c below).
Apologies if I am being a bit slow with this, but I would welcome some
input on solving this minor problem.

OK Im now using gcc -E as the preprocessor and it seems to compile and
make executables.
Triple test seemed to be ok, some issues with make TARGET=x86/linux
test, regarding mismatches in
the generated assembler but I'll check the messages.
Only needed to modify etc/linux.c
char *cpp[] = { LCCDIR "../../../../../usr/bin/gcc", "-E", //
modification to point to my /usr/bin/gcc install
"-U__GNUC__", "-D_POSIX_SOURCE", "-D__STDC__=1", "-D__STRICT_ANSI__",
"-Dunix", "-Di386", "-Dlinux",
"-D__unix__", "-D__i386__", "-D__linux__", "-D__signed__=signed",
"$1", "$2", "-o", "$3", 0 }; // modification to pass arguments to
generate intermediate filename
and here
int option(char *arg) {
if (strncmp(arg, "-lccdir=", 8) == 0) {
cpp[0] = concat(&arg[8], "/../../../../../usr/bin/gcc"); //
modification to not break cpp[0] calling/storingimeddd gcc
// cpp[1] already has -E stored
Thanks,
Andy
