Subject: ppoll()/generic select() only available with libc
X-Git-Tag: RELEASE-0.4~5
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=7e523af6ee8ecc424e5a83347f444516d0fd4c5c;p=unikraft%2Flibs%2Flwip.git

ppoll()/generic select() only available with libc

The options LWIP_SOCKET_SELECT_GENERIC_FDS and LWIP_SOCKET_PPOLL are
only made available when a proper libc (HAVE_LIBC) is added and
enabled to the build. These options do not work with nolibc.
