run the program as this: $ LD_ASSUME_KERNEL=2.4.1 ./a.out unless the program is a simple 'hello world', expect it to crash sooner or later; the linux compat layer in OpenBSD is outdated, and doesn't implement many syscalls from linux 2.6.x (and if you linked the binary against a recent glibc, it may not work with older kernels).
