Compiling Jo Engine under GCC 7.2.0

<< < (2/3) > >>

neoraph:
Hello  :)

Any news about that question?

I am working on a Mac, and I wonder to use a docker image based on a linux (probably debian) and if I can use the latest gcc, it should be nice :)

Hi, I'm sorry, I don't have enough time to work on the Engine today, but It will change. I hope  :)

mindslight:
You have to recompile the standard C library and add the path in your environment.

The library currently used in the project is available here: "Compiler\SH_COFF\sh-coff\sh-coff\lib\libc.a"

If you look closer into the "compile.bat script", you will see paths :


--- Code: ---
SET PATH=%COMPILER_DIR%\SH_COFF\Other Utilities;%COMPILER_DIR%\SH_COFF\sh-coff\bin;%COMPILER_DIR%\TOOLS;%PATH%
--- End code ---

You will find in attachement the C library compiled (ELF Format) (old version but enough)

Any luck with this? I'm interested in compiling on linux without wine. However I'm not very familiar with compilation for different targets.

abrasive:
I was able to do this without much fuss with GCC 7.3.0 (sh-none-elf).

You can use the included COFF libc.a. You need to make sure -lc comes after all the $(LIBS) though. In my case I used:

LIBS += -L./lib/joengine/Compiler/SH_COFF/sh-coff/sh-coff/lib/ -lc -Wl,--format=elf32-sh -lgcc
