Your ghc is your native (amd64) compiler (provided by debian as a package)? If so, then this is not supported. You need to compile ghc from source and configure it as a cross-compiler. Another problem is that armv7-m supports only thumb-2 isns while GHC HEAD IIRC switched to arm isns solely. The last problem may be lack of support for armv7-m in GHC's RTS (runtime) or for your (probably?) RTOS which you run on armv7-m? Karel On 02/ 6/16 04:19 PM, Fabien R wrote:

Hello,

I would like to link my Haskell module with existing object files for armv7-m. I use ghc 7.4.1 on debian/amd64.

This command seems incorrect or incomplete: ghc -pgmcarm-none-eabi-gcc -pgmParm-none-eabi-cpp -pgmaarm-none-eabi-as -pgmlarm-none-eabi-ld -keep-tmp-files HaskellModule.hs

A lot of errors appeared: [1 of 1] Compiling HaskellModule ( HaskellModule.hs, HaskellModule.o ) /tmp/ghc13654_0/ghc13654_0.s: Assembler messages:

Any hints ?
