I'm trying ccl on raspbian (on qemu-arm, waiting for a real Raspberry Pi).

(log 1217) returns 0.0 instead of 7.104144.

I'm running a similar Qemu installation, but with the default user networking instead of tun/tap.

./opt/bin/qemu-system-arm \

-kernel kernel-qemu \ -cpu arm1136-r2 \ -M versatilepb \ -no-reboot \ -append "root=/dev/sda2 panic=1" \ -hda 2012-07-15-wheezy-raspbian.img

I get the same 0.0 result on (log 1217), or any integer.

Building the kernel gets an error with the standard setting of "FLOAT_ABI = softfp" in "lisp-kernel/linuxarm/". Changing it to "FLOAT_ABI = hard" makes the build succeed and makes LOG work correctly.

  • Resolution set to notabug
  • Status changed from new to closed

There's enough variance in ARM Linux distributions (which may support the hard-float ABI, the soft-float ABI, or both, and which differ in how this support is provided) that I don't think that we can do much besides making people aware of the issues and requiring them to edit
