Hauke Mehrtens 336ad4c9aa toolchain/uClibc: enable UCLIBC_HAS_OBSOLETE_BSD_SIGNAL ... This is required to build net-snmp. If that options is disabled in uClibc then net-snmp doesn't detect sighold support on its configuration stage and so defines HAVE_SIGHOLD as 0. That in its turn causes compilation of the following branch of timerPause() in apps/snmpnetstat: ------------------>8---------------- int oldmask; oldmask = sigblock(sigmask(SIGALRM)); if (!signalled) { sigpause(0); } sigsetmask(oldmask); ------------------>8---------------- Now in uClibc all 3 sigblock(), sigmask() and sigsetmask() were removed back in 2005, see: https://git.busybox.net/uClibc/commit/?id=5aa7aa7fa7ec2a0fe567ac0b2595b46add6f3594 And all that causes net-snmp linkage to fail this way: ------------------>8---------------- .libs/if.o: In function `intpr': if.c:(.text+0x908): undefined reference to `sigmask' if.c:(.text+0x90e): undefined reference to `sigblock' if.c:(.text+0x924): undefined reference to `sigsetmask' ------------------>8---------------- If we enable UCLIBC_HAS_OBSOLETE_BSD_SIGNAL in uClibc then branch with sighold is used in timerPause() and everything builds as expected.
