Hi, I successfully compiled a native GHC 7.8 RC2 from the source distribution. I now want to create an GHC cross compiler targeting ARM. So I do a ./configure --target=arm-linux-gnueabi --with-gcc=arm-linux-gnueabi-gcc (I don't know why I have to explicitly supply the GCC, documentation seems to suggest that it would pick that up based on target, which it seems to do for ld.) I then make a copy of the mk/build.mk.sample and place it at mk/build.mk and uncomment the BuildFlavour = quick-cross line. At this point I run make and it goes along happily until...

If it is a real problem then I can file a ticket. If there is anything I can do to help try and get GHC cross compiling for ARM I would gladly do what I can. Regards, Luke
