Bug 105361 – dev-lang/icc-9.0.021 uses gcc's C++ include files instead of its own

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Peter Simons 2005-09-09 04:16:07 UTC]

The default search path for ICC's header files as installed by Gentoo is:

 /opt/intel/compiler90/substitute_headers/c++
 /usr/lib/gcc-lib/PLATFORM/include/g++-v3
 /usr/lib/gcc-lib/PLATFORM/include/g++-v3/PLATFORM
 /usr/lib/gcc-lib/PLATFORM/include/g++-v3/backward
 /opt/intel/compiler90/include
 /opt/intel/compiler90/substitute_headers
 /usr/include

This means, that including a C++ header like <cstdio> will get the file
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5-20050130/include/g++-v3/cstdio instead
of /opt/intel/compiler90/include/c++/cstdio, like it should. This causes
compilation to fail.

Reproducible: Always

A very simple (albeit somewhat unsatisfying) fix is:

 # cd /opt/intel/compiler90/substitute_headers
 # ln -s ../include/c++

Another option to solve this problem is to use ICC with the following flags:

  CFLAGS="-no-gcc"
  CXXFLAGS="-no-gcc -cxxlib-icc"
  LDFLAGS="-cxxlib-icc"

ICC's -help output claims "-cxxlib-icc" would be a _linker_ flag, but in fact it
changes the definition of the include search path too.

The only version left in the tree is 9.1.045; reopen if it's still a problem there.
