For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now. If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or please mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already.

I have created a tarball which contains the sh4 chroot from the example above which also includes ghc, gcc and the source code in question (in /root/ghc-7.8.4/utils/ghc-pwd). To test, it's probably a good idea to replace the qemu-sh4-static binary in /usr/bin with a current git snapshot (which I tried but didn't help). > http://users.physik.fu-berlin.de/~glaubitz/sid-sh4-sbuild-ghc.tgz In case anyone wants to try ghc with their own sh4 chroot, here's my version of ghc: > https://people.debian.org/~glaubitz/sh4-unknown-linux-gnu- ghc-7.10.3.tar.gz Just extract this tarball into the root directory of the sh4 chroot. Please note, that it might be advisable on sh4 to apply the patches from these two bug reports as otherwise qemu-sh4-static won't work properly on amd64 and misses syscall 186: > https://bugs.launchpad.net/ubuntu/+source/qemu-linaro/+bug/1254824 > https://bugs.launchpad.net/qemu/+bug/1516408 The above issue is reproducible with the two patches applied and without. It's also reproducible with both libc6 2.19 and 2.21 in the chroot. Thus, I am currently out of ideas what else to test.
