Re: Configuring GCC 4.8.1, Unable to find a usable ISL

[Ivan Stalev <idstalev at gmail dot com>]

Unfortunately, I keep getting build errors:

g++: unrecognized option '-static-libstdc++'
conftest.cpp:11:2: error: #error -static-libstdc++ not implemented

conftest.c:18: error: 'choke' undeclared (first use in this function)
conftest.c:18: error: (Each undeclared identifier is reported only once
conftest.c:18: error: for each function it appears in.)
conftest.c:18: error: expected ';' before 'me'
