Code::Blocks - DC Dev R1 *refixed*

[emptythought]

Here is the official release of my Dreamcast setup for Code::Blocks. Thanks to starlight for pointing out the SDL issues in my WIP release (they're now working).

About R1:
- upgraded to Code::Blocks svn (1.0 RC2 support dropped)
- no Makefiles needed
- includes Dreamcast sh-elf compiler (GCC 3.4.6)
- building romdisks within the IDE
- project files for most of KOS' Dreamcast examples
- configuration program automatically sets Dreamcast compiler for you
- easy uninstallation

Downloads:
CodeBlocks_DCDev_R1.exe (refixed 12/19/07)
cbdc_dep.zip (fixed 12/19/07) (this is for DC Dev ISO R2 and newer - sets the Dreamcast compiler up in Code::Blocks to use the Dev ISO's path rather than using the compiler in the "independent" installer)
manconf.zip (includes HTML manual-setup instructions for integrating CodeBlocks with Dev ISO R2 and newer, and the Dreamcast script used for the Dreamcast wizard)

Credits:
JMD for bin2odc.exe (used for romdisks)
pnpbios for the original Code::Blocks for DC thread

The installer doesn't work. can't seem to actually click the install button, or change the install path.

[emptythought]

I configured the installer to check for codeblocks.exe in the upper path, so make sure you select the folder CodeBlocks is installed in and add \dc. Also make sure the path you select has Code::Blocks svn, not 1.0 RC2.

[Covar]

ah ok, i got it to install now.

quick question though, to compile i will need to install cygwin?

Nope!

[Covar]

i didn't think so since you mentioned it, but when i try and compile a dreamcast project it tells me it sh-elf-gcc.exe needs cygwin1.dll to continue.

[emptythought]

I probably forgot to change the additional path under the toolchain executables tab and missed it because I have Cygwin installed. I'm almost 100% sure that's the problem. For now, you can fix it by changing "C:\cygwin\bin" to "C:\Program Files\CodeBlocks\dc\bin"...

[Covar]

That works much better now. and i must say this is great. by far the fastest i went from installing a toolchain to having a working dc binary.

[Arqueiro]

thanks for share this with us!

[Arqueiro]

to use the installer i need first have this Code::Blocks svn installed right ?

[emptythought]

Yes. Otherwise the Install button is grayed out. Any current SVN should work, I can't remember what revision I used but anything over 42xx should work.

[Arqueiro]

this is what is happening with me,

when i use the last version, available on the official site, the installation pack dont work. (codeblocks-1.0rc2)

when i install a old version, (codeblocks-1.0-rc1.1) it goes and install it but i got some errors when start the program (some incompatible pluguins)


which version are you guys working ?

[emptythought]

OK, you're not using a SVN. None of the official releases will work.

Uninstall the release you have installed, create a folder in Program Files call CodeBlocks, download the latest SVN from here and extract it there.

thanks for you help fackue, im trying to compile a example that come with the KOS:

anyone have idea why this is happening ?


thanks

[emptythought]

anyone have idea why this is happening ?

It has to do with wfont and the romdisk not getting linked but to get wfont linked correctly it needs to be converted to an object file and the program we're using to do this has the romdisk symbols hardcoded. I had some issues compiling the bin2odc's source. I was looking into creating the symbols at runtime. I tried manually changing the symbols and could not get it linking right so even if I did get the source to compile right I was not sure how to set the symbols. If you have to have wfont.o, I compilied the example in Cygwin then copied it to the example in CodeBlocks and linked it and it compiled fine.

First of all thank you for all this.
I tried to set up devC++ but it seems the ELF files won't work when making the iso because of the linker order, is there any way to successfully compile in devC++?
Well I can't install CODEBLOCKS dc config I get this error ( I'm using one of the latest codeblocks SVN ) "open and close Codeblocks and then continue" default.conf not found.
Point is that no default.conf is generated and even If I copy that file from the documents and settings/user/programdata/codeblocks it does not recognize it.......

It doesn't give me the error with CodeBlocks November 28 svn. Also - you shouldn't have to copy it to anywhere. Once you open CodeBlocks for the first time and close it it creates default.conf. You might have to save the layout if it asks you to but I would of said that before if you needed to.

There wasn't when I tried it.

Well I open it and close it and no default.conf is created, the only default.conf is on
documents and settings/user/programdata/codeblocks/
It is still giving me that error, weird....
BTW I have the latest CODEBLOCKS SVN.

Where can I download a precompiled linux toolchain ( .rpm package or compressed one )?
Since consolevision is down many of the forum downloads are gone

Does it have read-only or hidden flags set?

Nope.

Any tutorial on how to configure it? I'd appreciate, Thanks.
We're starting a project for dc that might see a demo on christmas or january if all goes well.

Now I only have to set the dev environment on linux, I did it manually for windows
