They do, or they are started from a linux sh which is somewhat equivalent. Status: - static linux executables need(ed) to be branded, else you may have experienced a reboot (branding changes the ELF ABI number) - the code which is responsible to pick the correct syscall table (the FreeBSD one or the Linuxulator one) improved since ... uhm ... maybe 7.x - it is unknown to me (one of the few persons with the hands in the linuxulator infrastructure ports) if there is still the hard requirement to brand static linux programs - the only officially supported way to run (static and dynamically linked) linux programs, is to brand them first, if you don't brand them, do not complain if they do not work (brand and retest, only after that I start to listen) Regarding the problem at hand: - problems you see with linux programs may be kernel or userland related - kernel problems are linuxulator problems - userland problems are linux base/libs problems - the linux userland we use is Fedora 10 based, if the software which exposes problems is not supported by the vendor/author on Fedora 10, we do not support it either According to http://www.redhat.com/archives/posix-c++-wg/2009-August/msg2.html: ---snip--- Since STB_GNU_UNIQUE is a Linux extension the OS ABI indicated in the ELF header must be ELFOSABI_LINUX. ---snip--- and ---snip--- Anyway, this all is implemented in the toolchain used in Fedora 12 which is at this point the rawhide toolchain. It now appears to be working fine and due to the initial set of problems we showed up we know it is used. ---snip--- This sugegst you try to run a program for Fedora 12 on our Fedora 10 infrastructure. This is not supported. The only way to get this working is to use a (not existing) Fedora 12 linux_base. If someone wants to change the fact that there is no Fedora 12 (or newer) linux_base: feel free to have a look at the linux_base-f10 port and port Fedora 12 (or newer). If you have questions about porting a newer linux_base, feel free to ask here, I'm sure you will get answers.

(2) can you provide us with a small testcase (like a one-line program trying to use libstdc++ in a smiliar way)? Regarding the testcase, my linux executable itself doesn't use the symbol _ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE. Instead it links with some open source shared libraries, some of which probably links to this symbol. But looking at the readelf output it's pretty clear what triggers the problem.
