Bug 427816 – sys-apps/sandbox: fails to build on arm uclibc because eabi does not support utime syscall

• Status: RESOLVED DUPLICATE of bug 425006
• Product: Portage Development

[Description Anthony Basile 2012-07-23 22:01:02 UTC]

According to /usr/include/asm/unistd.h, we have:

/*
 * The following syscalls are obsolete and no longer available for EABI.
 */
#if defined(__ARM_EABI__)
#undef __NR_time
#undef __NR_umount
#undef __NR_stime
#undef __NR_alarm
#undef __NR_utime
#undef __NR_getrlimit
#undef __NR_select
#undef __NR_readdir
#undef __NR_mmap
#undef __NR_socketcall
#undef __NR_syscall
#undef __NR_ipc
#endif

So sandbox fails with

The obvious solution is to remove utime from sandbox --- I have a patch which I'll attach --- but I'm not sure where or how to apply this.  You have to test for 1) arch=arm, 2) libc=uclibc and 3) abi=eabi.  Ideally sandbox should check the system for what syscalls are available, but that sounds like a tough problem --- maybe compile tests in configure.ac?




Reproducible: Always

Sorry for the long cc, not sure who this bug belongs to.
