| | 6 | # |
| | 7 | # AX_PROG_CXX_FOR_BUILD |
| | 8 | # |
| | 9 | # DESCRIPTION |
| | 10 | # |
| | 11 | # This macro searches for a C++ compiler that generates native |
| | 12 | # executables, that is a C++ compiler that surely is not a cross-compiler. |
| | 13 | # This can be useful if you have to generate source code at compile-time |
| | 14 | # like for example GCC does. |
| | 15 | # |
| | 16 | # The macro sets the CXX_FOR_BUILD and CXXCPP_FOR_BUILD macros to anything |
| | 17 | # needed to compile or link (CXX_FOR_BUILD) and preprocess |
| | 18 | # (CXXCPP_FOR_BUILD). The value of these variables can be overridden by |
| | 19 | # the user by specifying a compiler with an environment variable (like you |
| | 20 | # do for standard CXX). |
