propgcc build fails in binutils tc-propeller.c

Heater.

The binutils of performance branch fails to build now on my laptop with Debian wheezy, gcc version 4.7.2 (Debian 4.7.2-4).

Like so:

gcc -DHAVE_CONFIG_H -I. -I../../../propgcc/binutils/gas  -I. -I../../../propgcc/binutils/gas -I../bfd -I../../../propgcc/binutils/gas/config -I../../../propgcc/binutils/gas/../include -I../../../propgcc/binutils/gas/.. -I../../../propgcc/binutils/gas/../bfd -DLOCALEDIR="\"/opt/parallax/share/locale\""  -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Werror -g -O2 -MT tc-propeller.o -MD -MP -MF .deps/tc-propeller.Tpo -c -o tc-propeller.o `test -f 'config/tc-propeller.c' || echo '../../../propgcc/binutils/gas/'`config/tc-propeller.c
../../../propgcc/binutils/gas/config/tc-propeller.c: In function ‘md_assemble’:
../../../propgcc/binutils/gas/config/tc-propeller.c:1841:2: error: assuming signed overflow does not occur when assuming that (X - c) > X is always false [-Werror=strict-overflow]

Daniel, since you have a Wheezy, can you please try this?
Do cd propgcc, hg pull, hg update performance, then ./jbuild.sh 4 rm-all

I get a completely different error when trying to build binutils on Wheezy:

syslex.l:31:21: fatal error: sysinfo.h: No such file or directory
compilation terminated.
make[2]: *** [syslex.o] Error 1

which sounds like I'm missing some libraries, but I can't seem to find what could be missing. Did you encounter anything like this in Wheezy, Heater?

Eric

Heater.

No, I have not seen that. Which sysfs.h could it mean? Perhaps I have some lib installed that you do not.

Heater.

Sounds like you need to install libsysfs-dev

Heater.

Out of curiosity I just pulled and compiled the "p2test" branch of propgcc. It compiled with no problems (after installing ncurses dev libs).

Edit: The "default" branch builds OK as well.

On going back to the "performance" branch the build fails as described in my opening post.

I had to fix that problem in the p2test branch to build under Windows I think. It isn't checked into the default branch though.

Sorry it took me a while to get to this, but I think the performance branch should build now on Wheezy (the problem was fixed in the trunk after the performance branch was forked, so we just needed to move the fix to the branch).

Heater.

Eric,

That fix seems to have worked but now the build fails at:

Which is the problem with underscores in HEX numbers I think I have reported before.

ersmith

I don't understand why the assembler is choking on this under Wheezy -- it works under Ubuntu. I'm guessing it has something to do with assembling it under gcc with the preprocessor instead of calling propeller-elf-as directly. Rather than spend a lot of time trying to track this down, I've removed the underscores. I hope this makes things work!

Eric

Heater.

That's just what I did here already. Builds fine now.
