Beginner Setup

[Pavel5750cz]

Hello. I am trying to make devkit work. I got the environment variables and paths are working, tried to solve wioth gpt, sometimes build work and when neeed most they dont, if it builds dol, it works on wii only(not have Wii U and dolphin says ,,Failed to init core,,).

The Problem::
It cant find libogc, giving it the path via envis(Environment Variables) or telling it absolute path and if it manages to find em, it pastes error i pasted under this MakeFile(Also its my first post so i try best to describe helpfull stuff for better help):

Code: Select all

# Compiler
CXX = powerpc-eabi-g++

# Compiler flags
CXXFLAGS = -std=gnu++11 -Wall
CFLAGS   = -Wall

# Linker flags
LDFLAGS = -LC:\devkitPro\libogc\lib\wii -logc -lwiiuse -lbte -mogc

# Include paths
INCLUDES = -IC:\devkitPro\libogc\include

# Target executable
TARGET = boot.dol

# Source files
SRCS = Hlavnoste.cpp

# Object files
OBJS = $(SRCS:.cpp=.o)

# Rule to build the executable
$(TARGET): $(OBJS)
	$(CXX) $^ -o $@ $(LDFLAGS)

# Rule to build object files from source files
%.o: %.cpp
	$(CXX) $(CXXFLAGS) $(INCLUDES) -c $< -o $@

# Rule to clean up the project
.PHONY: clean
clean:
	rm -f $(OBJS) $(TARGET)

Here is the messy error:

make: *** [Makefile:25: boot.dol] Error 1

I have newest version, even reinstalled devkit, path are like here: edit: removed random youtube video.

Using Visual Studio Code and i hope i wrote this problem(first post here) understandably enough and I will be happy to try your answer that might help me and others who have the same problem.

The Problem(Again for better reading/solving experience)::
It cant find libogc, giving it the path via envis(Environment Variables) or telling it absolute path and if it manages to find em, it pastes error i pasted under this MakeFile.

Hi!

thanks for reaching out to use. thanks for being so detailed on the issue, and providing your makefile & error log.
From what you posted, your makefile seems to contain some issues. this is why we generally tell people to use our template Makefile to make it easier for them as it includes all the rules, dependency and library stuff that is needed to make an application. What i linked to, for example, is the Makefile template for wii development. gamecube and wiiu (not vwii) are a bit different.

anyway,
in your LDFLAGS, you are adding -mogc, in which you are telling it to compile for gamecube (this is what our gamecube_rules would add). this is probably the problem of all the linking errors, as the functions it is looking for are all wii functions (and you are adding the wii libogc too).

i'd either use our template for ease, and to prevent any future issues you might come across, or replace the -mogc with -mrvl, which tells the linker we are linking for wii instead of gamecube

Have fun!

Thank you. I dont have much experience with Makefile as i have with Gradle on android so i blindly pasted your makefile and it errors too(i will post once i get on pc today). Then i pasted from gpt and sometimes it worked, and that working makefile not sure if i have but if i find and works, i paste it for you to ease your help to others. I know wildcard, -L -I and src. I have 1 cpp and wanna compile for more platforns at once, no idea to compile with no errors, will paste em when i can. Also i would like to make it work on dolphin too. If managed to do dol, dolphin says Failed to init core and when i pet others try it works on their. Well i will paste error when i get to pc

to me it sounds like we need to first work on getting the code compiled with the template makefile. the mix-match of gamecube & wii targetting is probably what is confusing dolphin i think.

but im looking forward in seeing the error log of compiling with the template makefile

[Pavel5750cz]

When i get more experienced, i would like to also help others. Now here is error your makefile in template for wii gives from devkitpro/examples/template/wii.

(Some time later i got on pc and then i finish message):

Surprisingly it works but it gotta in specific folder i tried to just use the single cpp(not entire folder) which gave issues. I am ok now, later i try connect just one file, gona be in folder, when i get experienced then i edit maybe but I rately do this even with Gradle so maybe no. God knows.


Message for those whose Makefile from devkitPro is not working:
1. Check Envis(Environment Variables): DEVKITARM has /opt/devkitPro/devkitARM
DEVKITPPC has /opt/devkitPro/devkitPPC
DEVKITPRO has /opt/devkitPro
/opt/ is same as C: but it tells windows, its not part of system(found on a reddit post when googling because i was interested in diference also)

2. If you use ChatGPT to paste path, check :
A ) that devkitPro has big P in it(i had such experience)
B ) libogc path does not have portlibs because it does not exist anymore.
3. Correct libogc path is /devkitPro/libogc/include for -I(Big i not small L)and
/devkitPro/libogc/lib/(wii or cube) for -L

And set the /devkitPro/libogc/include path in Envis called Path and restart Windows after pressing OK. It allows you use gccore, wiiuse and lot in <> intead of "" and no need for absolute paths like <C:/somewhere/for/PPC.h>

Thank you for response. I hope answer did also some help to others. I will start makong my cross platform game to wii and then release. I will donate when i get coins but not small amount.

Hey, any updates on your errorlog that you were going to post?
meanwhile Wintermute made an example of how you could build for multiple platforms using a single Makefile and/or cmake.
when you run make, it will build the gamecube version, and if you run make with the parameters PLATFORM=WII it will build the wii version

please use this template to make a first draft of your program to target the wii and gamecube

When i am now gonna work from linux after doing game for other platforms too, makefile may change and i am not sure if i post here. orry it took long time, i had limited pc and phone access and then i was workin and forgot. This makefile i use, may help other windows developers too. for linux and mac you may need configuration.

I may post linux makefile later.
