Setup Gendev linux [Solved]

CRAP! continue reading:

Just stick to the instructions.

make.exe is a Windows binary. You are on Linux.

Sure, obviously.

This is what Gendev builds for me, windows executables in a linux package. I only followed the instructables.

How do you configure codeblocks (or any other ide) to compile from linux? i've used "make" in project's directory terminal, it does generate a output .bin rom, but it does not work. (windows done this great).

btw i am compiling the Hello world example.

Wrong makefile. You want gendev/sgdk/skeleton/Makefile

EDIT: It also appears your Code::Blocks projects is configured to use "make.exe" explicitly so you will probably want to change that as well. I don't use that IDE so I can't tell you where that is configured though.

seems you have a working linux sgdk enviorment....can i ask you for a little tutorial for dummies PLEAAASEEE???

[Grind]

I'm not very good at tutorials but maybe this will explain it

Build Gendev

Code: Select all

sudo apt-get install build-essential texinfo
cd
git clone https://github.com/kubilus1/gendev
cd gendev
sudo make

Hello World program

Code: Select all

cd
cp gendev/sgdk/skeleton .
cd skeleton
mkdir src
cat <<EOF > src/main.c
#include <genesis.h>
void main() {
	VDP_init();
	VDP_drawText("Hello World!", 2, 2);
	while(1) {
		VDP_waitVSync();
	}
	return 0;
}
EOF
make

If something breaks that's probably because it is 12 AM and I didn't test these commands. Where are you stuck at the moment? Does "make" give you an error when you use the gendev makefile?

[Montserrat]

Thanks grind. That is what i previusly did, except for using cat to create a .c file i've used gedit...may be its the encoding?? i just moved to linux mint now because got problems to build gendev in debian, gonna start over again then ill tell you.

Got same results, a out.bin (and temp.bin) i load them into umdk but got blackscreen. Thats the terminal output:

also changed void man for int main (i think the compiler expected int), bug got similar results...

The log warns about some functions conflict memset, memcpy, strcmp and sprintf any ideas?

[Grind]

Did you only try UMDK or an emulator also? It has been some time since I last set up Gendev so I will try it again tonight or tomorrow in Ubuntu.

You can add an option to the compiler line "-nostdlib" or "-nobuiltin" don't quite remember which. That should get rid of the warnings.


As a bit of a side note, in the future it may be better to use Chris's cross compiler setup from UMDK to create our games. Problem is the makefiles are completely different than Gendev and the version of SGDK is old. When I have a solid free weekend I would like to come up with an example/instructions for updating SGDK in his environment as well as compiling a game with debugging. Second part should be easy basing it off the menu.

[Montserrat]

Only tried UMDK, since the rom i compiled in the sgdk windows version worked fine in the umdk i suposse there is no problem with the cart.

Also gonna ask Gendev creator aswell...

cd
cp gendev/sgdk/skeleton .

... should be cp -r gendev/sgdk/skeleton .

This means the boot dir wasn't copies and is likely wrong. I don't have a convenient way to verify this on real hardware ATM, but I could see this leading to a blank screen. First step would be to verify on emulator perhaps.

Fyi, take a look here for some very basic instructions: https://github.com/kubilus1/gendev/

This is what Gendev builds for me, windows executables in a linux package. I only followed the instructables.

Nope. No windows executables here at all. Gendev is 100% pureish *nix.

Don't know about IDEs, I never use them. Unless vim is considered an IDE.

Good luck and don't get discouraged. Getting a decent workflow that works for YOU is probably one of the most difficult parts of this stuff!

Yup thanks for reply, about the skeleton directory, yes i copied recursively. Also followed the official intructions with same results i did:

Code: Select all

sudo apt-get install build-essential texinfo git

git clone https://github.com/kubilus1/gendev.git

cd gendev

make

....building process.


 cp -r /opt/toolchains/gen/skeleton myfolder (also tried to copy cp -r gendev/sgdk/skeleton)
 cd myfolder

*type type type the hello world example from sgdk wiki* 

  make

It makes a rom.bin and a temp.bin, but with errors, pasted the terminal log above. i am missing something?

[kubilus1]

What about running the out.bin in an emulator? Does that work?

[Montserrat]

....done a fresh install on mint, now it works....i've done this 1000 times without results i dont know wtf has happened but...

... problem solved, it works now both emulator and UMDK.

Thanks for your time!

PD: mod can you close this thread?
