Build.sh fails with "error: incompatible function pointer"

[TemporaryUntemporary]

I am using MacOs 14.4.1 with Apple M3 Chip. I installed Apple's Roesetta on my system and followed the installation instructions of pokemon emerald.

While trying to build agbcc I have encountered the following error:

expr.c:8863:19: error: incompatible function pointer types initializing 'rtx (*)(rtx, rtx, rtx)' (aka 'struct rtx_def ()(struct rtx_def *, struct rtx_def *, struct rtx_def *)') with an expression of type 'rtx (rtx, ...)' (aka 'struct rtx_def *(struct rtx_def *, ...)') [-Wincompatible-function-pointer-types]
rtx (*gen_insn)(rtx, rtx, rtx) = GEN_FCN (icode);

I added the log as a text file, in case it helps.

This is a known issue. The solution is to install GCC from Homebrew or Macports. NOTE: Even though xcode gives you gcc, it's not actually gcc but rather apple clang wearing a troll mask. You can invoke the required version of gcc as (for homebrew) gcc-13.

I see. So the next steps would be to edit the file gcc/MakeFile and replace line 25

CC = gcc

with

CC = gcc-13

or am I missing something?

Sooo … it might work now.

build.sh
Download gcc (version 13) via homebrew (if not already installed)

brew install gcc@13

Add the lines

CC=gcc-13
export CC

in a new lines after CXXOPT= and use ./build.sh & co. as described in the manual. My previous answer worked, but only for one step as it did not set the compiler for the following processes. With export I make sure of that. Not sure if it is an elegant solution, but it works (for me).

Next thing to do is to update the package-list the command pkg-config has access to. Simply do

brew install pkg-config

This makes the packages in the homebrew environment available to pkg-config. (You will otherwise receive an error that "No package 'libpng' found" and that you should adapt "PKG_CONFIG_PATH")

make

Afterwards I used make as described in the manual. It did not complain and make compare did not complain either.

i tried this but ended up with an error message: 'make: gcc-13: No such file or directory'. Any ideas?

Did you install gcc like PikalaxALT mentioned?

brew install gcc@13

(It was already installed on my computer, so I did not mention it.)

That's done it hahah, thanks!
