nanogui: Thread: ask for c++ compiler of m68k

I wanna my microwin application run on Dragon Ball CPU,
and i got m68k Complier.
but my application base on c++, I only have m68k-pic-coff-gcc  to
instead of gcc, what can i do ? what is g++ complier in m68k?

You might want to direct this question to the uCLinux.org
mailing list, they've got Linux running on m68k and other
CPUs.

I use the same sort of compiler (in cygwin environment) where 
m68k-coff-gcc (the gcc driver) calls internally the m68k-coff-g++.
In my distribution (www.microcross.com), they are both located 
in /usr/bin.

I think your cross distribution should only miss somme link and path
to the actual compiler. Check the location of your actual 
m68k-pic-coff-g++ cross compiler which should be the same place as 
m68k-pic-coff-gcc.

If not, a low-cost cross distribution can be found at microcross
for linux or windows hosts and many targets.
That is the environment (windows hosted) that I used for flmwin 
and microwindows to run on my 68060 target.

thank u for u help.

but i got this complier from others, only find m68k-pic-coff-gcc
in /usr/loca/gnu/bin, there is no g++ compiler.

cuz of i am a newbie about gcc, could tell me some conception?
can gcc compile c++ program ? in X86 platfrom i use g++ not
gcc to do this.
as u said, i only should correct the links or add some path,
can u tell hwo to do in detail?


And another thing make me confuse is what's the difference
between m68k-pic-coff-gcc  and m68k-coff-gcc.

Regards

Daniel Wang

I suppose you are working on a UNIX-like host.
IMPORTANT : as I am not used to LINUX/UNIX environment, someone 
else should give a more accurate answer or correct the following.

(1) Either you have a path to /usr/loca/gnu/bin and m68k-pic-coff-gcc 
is a symbolic link to another location (e.g to
/usr/local/m68k-pic-coff/bin). 
Perhaps /usr/loca/gnu/bin/m68k-pic-coff-gcc link fails 
reaching m68k-pic-coff-g++ as it's actual location is
/usr/local/m68k-pic-coff/bin/. 
You could add the links to g++ and 
all other gcc stuff (as, ar, c++, etc) in /usr/loca/gnu/bin
pointing to /usr/local/m68k-pic-coff/bin ones (you'd better do 
that in a shell script and invoque this each time you want gcc
to point to the cross m68k-pic-coff cross version).

(2) or m68k-pic-coff-g++ is simply missing ! Try getting it from
the same place you found m68k-pic-coff-gcc ...
...or look at www.microcross.com. They have binaries covering a 
great range of targets (for near the cost of shipment and media).

Note that I did not find a documentation on paths for gcc *standard*
location (i.e. documented), that match *usual* 
paths of the binary distribution of those cross-compilers.

BTW if anyone knows about good and practical docs on this 
subject, I'am interested (i.e. what is the general philosophy
and the practical usage of --prefix in configure option).

The name of the actual gcc compiler is created by the *target*
option of "configure" when generating the compiler.
My m68k-coff-gcc comes from --target=m68k-coff in this case.
Look at gcc documentation at gnu.org or cygnus, about cross versions.
When you invoke "gcc" whithout options, it often means you use the 
native (host X host) compiler.
Dragon Ball (your's) and 68060 (mine) targets are not the same and 
some specific stuff has probably to be done in each version of the compiler.
