I pulled down revisions 56 of l4re per the l4re download instructions on an x86 platform running Ubuntu 13.04. I'm cross compiling for an ARM 8 Beaglebone platform. I created a set of tool links pointing to gcc, g++, ar, ld, etc. from the current Genode toolchain. I then followed the l4 build instructions. The build proceeded normally until is started to link in libc static libraries at which point the following errors killed the build: ... ==> Linking loader /home/bob/fiasco/builds/l4/lib/arm_armv7a/l4f/libuc_c.a(__exit_handler.o): In function `__new_exitfn': /home/bob/fiasco/builds/l4/pkg/uclibc/lib/uclibc/src/libc/stdlib/_atexit.c:259: undefined reference to `__emutls_v.__libc_errno'
Is there some undocumented compiler flag related to TLS I should be setting somewhere to fix these library references?
Not that I know of, it should just work. What do you mean with that you created links to binutils and gcc? When cross-compiling to ARM the tools should just be prefixed with arm-linux- and gcc/g++ etc. target the host.
