native 64bit toolchain on linux #212

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi,

after two weeks I've finally managed to fix odcctools and a corresponding gcc 
to compile successfully on 64bit linux.

I've created ubuntu packages on my launchpad ppa at

https://launchpad.net/~flosoft/+archive/ppa

There were 2 "big" bugs in the odcctools which caused the trouble with native 
64bit:

1. in include/foreign/machine/vm_types.h: the vm_address_t was forced to 32bit, 
but its used for storing memory addressing (->> CRASH)
2. in libmacho/arch.c: in the NXGetArchInfoFromCpuType you returned a non 
static pointer on a static table - the driverdriver tried to change the table 
(->> CRASH)

now it fully works on 64bit linux without need of "-m32" in the CFLAGS/LDFLAGS

the ppa-link changed: (created a apple-specific ppa)

Hi, you have to set "maverick" as distribution. if you're using an older 
ubuntu/debian, you should download the source packages and rebuild it for your 
system - with newer ubuntu/debian, its not a problem

I ran into that problem too if I was using "add-apt-repository 
ppa:flosoft/cross-apple"

            ccache extension for apple multi-arch file compilers.

now you have i686-apple-darwin10-* for 32/64bit apple binaries and 
powerpc-apple-darwin10-* for powerpc/powerpc64 binaries.

So you can compile i.e a "HelloWorld.c" with

i686-apple-darwin10-gcc -arch i386 -arch x86_64 -arch powerpc HelloWorld.c -o 
HelloWorld 

to an universal binary (the gcc will call the powerpc-variant as needed)

how did you compile and which errors do you get? (perhaps you should open a new 
issue?)
