makefile not working as intended? about pokeruby HOT 15 CLOSED

That is because you did not have the necessary compiler installed. I have added a README and INSTALL instructions. Let me know if you need any assistance.

from pokeruby.

thanks for the help! unfortunately even with the install instructions it seems like something goes wrong in the middle. i got up to successfully using build.sh, but install.sh seems to reference a file called libgcc.a that doesn't actually exist in agbcc -
"cp: cannot stat ‘libgcc/libgcc.a’: No such file or directory"
any idea where this might be?

from pokeruby.

build.sh is supposed to create that file. What does build.sh output? Could you put it on pastebin or something?

here you are! it's a doozy

from pokeruby.

It looks like there was an error building libgcc.a, but it isn't shown.

Could you run these commands in the "agbcc" directory?

make -C gcc clean
make -C gcc old

Then:

cd libgcc
make clean
make

You should see an error at the end of the output.

from pokeruby.

at make, i get:

rm -f tmplibgcc1.a
set -e

it seems as if there are some characters the assembler doesn't like?

from pokeruby.

Those errors are always after SIZE(...) in the asm file. SIZE(x) is replaced with ".size SYM(x), . - SYM(x)". Since the error is complaining about "-", it looks like the SYM(x) is being replaced with an empty string. This produces ".size , . -" which is an error. I don't know why that would happen though. If you type "cpp --version", what version is printed?

from pokeruby.

That is a slightly old version but it should work. What is the output of this command (in the libgcc directory)?

cpp -DL_udivsi3 -x assembler-with-cpp lib1thumb.asm

Is it different from this?

cpp -DL_udivsi3 lib1thumb.asm

from pokeruby.

they print the exact same thing:

Does this change anything?

cpp -nostdinc -undef -DL_udivsi3 lib1thumb.asm

from pokeruby.

that doesn't write

# 1 "/usr/include/stdc-predef.h" 1 3 4
# 1 "<command-line>" 2

but the rest is the same. didn't seem to change anything about the make working either.

from pokeruby.

Your output doesn't appear to be any different from what I see on my Linux VM. If you output that to a file and try to assemble it, do you still see the errors?

cpp -nostdinc -undef -DL_udivsi3 lib1thumb.asm >_udivsi3.s
$DEVKITARM/bin/arm-none-eabi-as -mcpu=arm7tdmi _udivsi3.s

from pokeruby.

This should be fixed now.
