[M3devel] more cm3cg on Raspberry Pi

[Jay K]

Oh, sorry, here are things to try

edit m3-sys/m3cc/src/platforms.quake
look for ARMEL_LINUX, change the right hand side to arm-linux-gnueabihf

and/or in src/m3makefile, you want to add -with-hard-float or -with-hardfloat..no, wait, from your other mail:

 And, really, the guide here is what you showed for gcc: 

 Configured with: ../src/configure  
    -v \ 
    ...  
    --with-arch=armv6  
    --with-fpu=vfp 
    --with-float=hard  
    --target=arm-linux-gnueabihf 

 One/some/all of those are relevant. 
 You might as well go ahead and throw them all in for now. 

 Hey -- isn't that C backend convenient? :)
