[TUTORIAL]How to program in D on the PSP!!!

[the_darkside_986]

The free, open-source GNU D compiler (dgcc) has been ported to MIPS and is known to compile under the psptoolchain now! This started because I asked someone on D.GNU how to compile it for the PSP and someone described a howto. I've posted the instructions here: http://forums.qj.net/showthread.php?t=142864 if anyone is interested.

There are still a few kinks to work out, but once things are smoother I think it would be nice to see this as a part of the standard toolchain distribution.

For those who have never heard of D, it is a powerful new systems programming language that compiles purely to native code, but has powerful language features of high level languages. These links explain it better than I can:
http://www.digitalmars.com/d/
http://www.digitalmars.com/d/1.0/overview.html
http://www.digitalmars.com/d/1.0/comparison.html

For now, developers will be limited to mostly using the standard C library (in std.c.* modules) and the PSPSDK headers (download link is in the QJ post, I converted them myself to D) until I can rewrite D's standard library, Phobos, to have proper PSP implementations of various classes and functions, which should be easy and straightforward. But I personally prefer using the SDK functions anyway.

Enjoy.

Cool! I'll have to try that out. I've been watching D since it was first introduced. It's a very nifty language. :)

EDIT: Got gdc compiled and installed. Example 2 works fine on my Slim running 4.01 M33-2. :D

Wow:p

Nice. I'll try it out tomoro. (1h AM here)

Cyaa

[KickinAezz]

D has great future!

I donot know why people seem so uninterested...

[whistler]

finally managed to compile psp-gdc and i have tested the demonstration eboot on 401m33 :)

great work

[Maxiime]

Post this on a psp site like pspgen, qj etc.

Ps: tested it. works great! tnx

Cya!

Post this on a psp site like pspgen, qj etc.

Some people here (me at first) don't like redirects like this. Please, don't...
(and that "cya", too....is it necessary? :P )

[Wraggster]

anychance of posting the tutorial in full here

[Moneyslap03]

thanks im setting up now and Wraggster didnt know you were signed up here its mike03$$$ from dcemu

I've been really wanting to get D working on the psp but bother as I thought there may be a few difficulties causing me to loose sleep. So I decided to posted this ;) hoping other dev's would rush in and try to 'win the race' (while not even playing) and it seemed to work brilliantly.

Anyway just skiming through right now 'bout to get more sleep. So is the full tango library working and GC tested?

[sauron_le_noir]

gcc patched and D compiled without problem but when generating libpspsdkA.o

i have the following error with the makefile provide

../../../libphobos/internal/cmain.d:5: référence indéfinie vers « _Dmain »
../../../libphobos/internal/cmain.d:5: référence indéfinie vers « _Dmain »

is this the main entry that must been written in C?



if have created a new makefile
just do make copyheader it copy all the *.d to $(SRCS) $(PSPSDK)/include/pspsdk
after this
make it compile create the libpspsdkD and copy it to $(PSPDIR)/lib

here is the makefile

PSPSDK=$(shell psp-config --pspsdk-path)
PSPDIR=$(shell psp-config --psp-prefix)

Yeah sorry about that I forgot to fix the Makefile before posting it. This is the latest version on the QJ thread's first page, right? I just fixed it and re-posted it the other day. There were some problems with pspgu headers (as usual for me).

[Heimdall]

any ideas if it can be aplyed to gcc 4.3?

[the_darkside_986]

Probably not, I've had problems with gdc compiled against 4.2, so 4.3 probably has the same issues or more unless that has been patched in svn yet.
