my link statement looks like this

Code:

m68k-amigaos-g++ -o <all my .o files>
-L"C:\cygwin\opt\amiga\m68k-amigaos\clib2\lib" -L"C:\cygwin\opt\amiga\m68k-amigaos\libnix\lib" -lc -lamiga -lm

i tried a define memset64 as memset in a header file but it didnt resolve it. any ideas? Im building with g++ with -O2 -noixemul

thanks

you did not update properly. delete the odl stuff, clean the build. and if you compile with -noixemul you must link using -noixemul too

lantus360 · 29 May 2018, 19:16

-noixemul in the linker fixed it. thanks!

lantus360 · 04 June 2018, 15:21

My exe compiled up just fine, but now i have another problem

any thoughts/help on trying to debug/fix an immediate hard crash on launch of my executable? (alternates between guru/winuae crash dump).

one thing i tried was to just stub out main() and return hello world and that crashes as well. stack size was set correctly. Im not even sure if my code is getting to main()

ideas are welcome. thanks!

have you set the emulator to use FPU or not? Did you define -msoft-float or -mhard-float on compile?

bebbo · 04 June 2018, 15:32

hello-stdio.c

Code:

#include <stdio.h>

int main()
{
  puts("hello world!\n");
  return 0;
}

will build and run with all 3 (4?) supported libs:

Code:

m68k-amigaos-gcc -Os -Wall -fomit-frame-pointer  -o hello-stdio hello-stdio.c
m68k-amigaos-gcc  -mcrt=nix13 -Os -Wall -fomit-frame-pointer  -o hello-stdio.nix13 hello-stdio.c
m68k-amigaos-gcc  -noixemul -Os -Wall -fomit-frame-pointer  -o hello-stdio.nix hello-stdio.c
m68k-amigaos-gcc  -mcrt=clib2 -Os -Wall -fomit-frame-pointer  -o hello-stdio.clib2 hello-stdio.c

I tried a few of these, but let me go back and test one at a time. Ill let you know what i find

Also worth to try with different optimizations (-O1, -O2, -O3, -Os)

no idea - all systems report no failure.

make clean clean-prefix -j
make update -j
make all -j4

Isn't it complaining about missing one of the startup files that libnix needs to make an executable (crt0.o)?

Yes, it is. And thus newlib was not build.

I had removed ira from the 'all" target of makefile. I did 'git checkout Makefile' to get the original makefile. Build breaks at building ira.

Something weird is going on.

Code:

make ira -n
mkdir -p build/ira
cd projects/ira && cc -o /home/alex/t/amiga-gcc/build/ira/ira -Os ira.c ira_2.c supp.c
mkdir -p /opt/amiga/gcc6/bin/
install build/ira/ira /opt/amiga/gcc6/bin/
echo "built /opt/amiga/gcc6/bin/ira"
echo "done" >build/ira/_done

!!!!????

Tries to make ira out of 3 files. If I cd to projects/ira and type make it builds!
Here's what make -n from within ira's folder says:

Code:

make -n
gcc -c -O2 -std=c99 -o obj/amiga_hunks.o  amiga_hunks.c
gcc -c -O2 -std=c99 -o obj/atari.o  atari.c

... well, I thought "git pull" is standard...
... recipe updated:

Code:

git pull
make clean clean-prefix -j 
make update -j 
make all -j4

The separation of 'git pull' and 'make update' may sound illogical but it is and helps me a lot to work with branches here and there.

alkis · 06 June 2018, 18:29

Yeap, that was it (git pull)

Thanks!

lantus360 · 21 June 2018, 18:48

this code

Code:

#include <stdio.h>

int main()
{
	FILE *f = fopen("test.c","rt");
	
	if (f)
	{
		printf("File opened!\n");
		fclose(f);
	}
	else
	{
		printf("File not opened\n");
	}

opens my file OK with

m68k-amigaos-gcc -o test test.c

but does not with

m68k-amigaos-gcc -o test test.c -noixemul

why?

edit: fails with -mcrt=nix13 but works with -mcrt=clib2

because libnix does not know the mode "rt".

-mcrt=clib2 -lSDL are the flags

My guess libSDL forgot to #include <inline/dos.h>
