Cross compiling for Cortex A9

[Michael Jones]

Karel,

My configure hack is now limited to two hacks on GHC 7.8.3. The vendor “pokey", and the ARM settings that make the target architecture correct. I also enabled profiling in build.mk. So pretty clean. No compiler options. GHC compiles clean.

I am getting a stack overflow during execution of the hello world applicaiton. I compiled like:

arm-poky-linux-gnueabi-ghc -static -debug -auto-all -caf-all -prof Main.hs

I ran on the target like:

./Main +RTS -Ds -Di -Db -DS -Dt -Da 2>log

I attached a log. Search for overflow.

created capset 0 of type 2
created capset 1 of type 3
cap 0: initialised
assigned cap 0 to capset 0
assigned cap 0 to capset 1
