Hello,
as a follow-up to my issues with using ICC with GCC 4.9, I now compiled GCC 4.8. How do I now tell ICC to use that? I've tried the -cxxlib=/path/to/gcc-48 switch. But what does it really expect the path to contain? Apparently a bin/g++, OK. But now I get this:
icpc: error #10001: could not find directory in which the set of libstdc++ include files resides
What does this mean? The last lines of output from a strace -f run is pasted below. Note how it finds e.g. /usr/lib/gcc/x86_64-unknown-linux-gnu/4.8.2/include but then tries to access /usr/include/g++ - why?
