AmiDevCpp upgrade

[AlfaRomeo]

Hi, which is the easiest way to replace the old GCC from AmiDevCpp by GCC 6?

I searched for any tutorials to upgrade the AmiDevCpp version of GCC but didn´t found any

I could do it in a few steps.

First, download setup & install in default location: https://github.com/SteveMoody73/amiga-gcc/releases

Then change only in "Tools / Compiler options" as follows

Create a new compiler (don't change anything else)



and set its path to point on the new compiler on next tab (don't change anything else)



then clean the dirs of all tabs (libs, includes, ...). Tedious as there are a lot and you can remove them one at a time only... Add them if you have extra libs. Not for now...



change executable names (as they have now the proper cross prefix: m68k-amigaos-). I have also changed the debugger, but I must admit I didn't try it, but I saw someone debugging from Eclipse, so why not from AmiDevCPP?



Simple enough ?

Of course, in your project, now choose this compiler.

(I suppose that we could configure the standard Code::Blocks exactly the same way BTW). Although, I must say that I don't consider Code::Blocks as top notch either.

In a few months maybe I'll be able to recommend you a better environment as Gnat Programming Studio / gprbuild (that I currently use in both professional & leisure environments for Windows AND Amiga cross dev, but the free version isn't so great yet, since they usually release the free versions once a year to the FSF and they want their customers to keep the advantage).

Thanks for your help jotd

Your steps seems easy, will try them during the weekend

Already installed GCC 6 and all runs well but when I run a SDL example code the compiler give the error: "cannot find -lSDLstub"
I googled about but didn´t find anything useful about any SDLstub library.
So I tried to remove the "-lSDLstub" from the Linker Parameters and the compiler give those errors:

I copied SDL includes folder inside sys-include folder but still with same errors


Any ideas?

SDL is built-in in GCC6. But You have to add -lSDL not SDLstub. Also add -ldebug to define kprintf.
Finally, I found out that the "signal" function wasn't defined. I stubbed it (empty) and it linked and worked.

Thanks jotd
It worked without SDLstubs with some compiler warnings.
I included that lib because I already included it when compiled sdl code in the original version of AmiDevCpp and allways worked.

This GCC 6 Amiga port & packaging is just great. One example? ok

for(;;);

translates to

.here
   bra.b  .here     ; $60FE

You may be disappointed by SDL performance as it needs 8 bit display (for the buffer) then performs a c2p conversion: no so fast (but beats graphics lib PutPixel ). The AGA hack is supposed to be better performance-wise (probably because it has a better c2p conversion), I didn't try it. I'm currently trying to get rid of SDL.

SDL will be allways slow in classic amiga

but it's interesting to quickly port some alien software, fire it on winuae with JIT and there it flies. Disheartening when you remove JIT ...

for me the magic moment was: 1. install GCC 6 with the setup, 2. connect it to my ide in a few minutes and 3. get an amiga executable.... on Windows...
Unthinkable even a few years ago, specially the "non-cygwin" part, which allows to use compiler in native batch scripts, python, you name it.
