Okay, I've setup the Makefile to test for writeability of /opt before asking for sudo for the directory creation. If sudo is used, the /opt/toolchains/gen directory will be chown'd back to the user. This should cover the bases I would think.

I'm interested in exploring whether this toolchain can be ported to jailbroken iOS - I already have several non-standard (in iOS land) tools installed (gcc, etc) but I'm not sure if I have the full complement. I would love to be able to take my iPad around and code for the Genesis when I have some downtime.

Unfortunately, I have little skill with modern development so I fear I might be in over my head. Anyone willing to work with me to help me attempt to get this type of stuff set up? Alternately, all I really need is an assembler for basic stuff (and eventually an art editor/converter). I don't need much other than the bare minimum necessary to port a crossassembler and some other basic tools. I don't want them to have a fancy iOS interface, I'd be running them from a terminal on the device.

It ought to be pretty straightforward getting this toolchain to work mac OSX since I've already done some work for this on FreeBSD in the past. Unfortunately, I know absolutely nothing about iOS, so can't say if this is feasible or not.

From doing a bit of work on Android, I would expect this would not be an easy task to get to work natively.

If iOS can run virtual machines, you could use the Vagrantfile I posted previously and perhaps convert that VM into something iOS can use.

I'll erase the gen directory and try again from scratch and see what happens. :)

No problem. What I'd really like to do is work in better 32X support so I can use sgdk for both Genesis and 32X stuff.

After installing Xubuntu 14.04.1 (32bits), i'm blocked in the first make:

Code: Select all

megadrive@centrino:~$ svn checkout http://gendev.googlecode.com/svn/trunk/ gendev-read-only
Checked out revision 101.
megadrive@centrino:~$ cd gendev-read-only/
megadrive@centrino:~/gendev-read-only$ make

	patch -u < ../files/makefile-gen.diff || true && \
	MAKE=make make -f makefile-gen
patching file makefile-gen
Reversed (or previously applied) patch detected!  Assume -R? [n] 
If I say 'y', I get the following message:

Code: Select all

I think the error is that binutils-2.21 package is missing, so I try to install it:

Code: Select all

megadrive@centrino:~/gendev-read-only$ sudo apt-get install binutils

But it's already installed... :? Let's try again the make:

Code: Select all

megadrive@centrino:~/gendev-read-only$ make
echo "Build"

What I'm doing wrong? I've ran `make distclean' and `rm ./config.cache' and started the process but no luck.

Thanks in advance and sorry for the long post.

You will need to do a 'make clean' and then a 'make'. I think it is attempting to rebuild already built stuff.

The toolchain built fine, but when I went to build sgdk, it doesn't build. The reason is this:

Code: Select all

sgdk-read-only/libmd.a:
	cd sgdk-read-only && ln -sf ../files/Makefile.sgdk_lib .
	cd sgdk-read-only && $(MAKE) -f Makefile.sgdk_lib
It's making a link to a file that doesn't exist, so nothing gets built.

Okay, did a svn up and it added the missing file. Compiled just fine. :)

Now I can work on the SMS Phazer support.

Another question, how long does it take the first make?
I started the process about 5 hours ago and it is still compiling in my old Pentium M (a 2005 laptop) :?

On that old laptop, hours and hours for the first make. However, you should rarely ever have to run that again once you get this set up.

Almost all my other updates will be in the sgdk directory and that compiles quickly.

(Note: I did include a .deb of the build environment awhile back but it is pretty darn old now. Building a .deb could be done and hosted by a user with the online space, the process is run from the Makefile.)

Yes, I finally have my environment compiled. Thanks for your help kubilus1!
I'd make a package/dev-only distro, but I think everybody uses 64bits processors for developing. not recycled computers (as me :oops: :lol: )

64-bit people can use 32-bit executables. I used to use a 32-bit SBC the year before, but then got an AMD A6 based 64-bit system - for less than $200. It's sick how cheap these things are getting. I spent far more than that on my first 8-bit system, which was chosen for being one of the least expensive 8-bitters on the market.

I'm now using m68k-elf-gcc, sdcc, zasm and sjasm built using ArchLinux recipes, but I still find this project very useful for building SGDK and the remaining tools.

Keep up the good work!
