C++ compile link

This is output from ./configure –help

CC          C compiler command
CFLAGS      C compiler flags
LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
            nonstandard directory <lib dir>
LIBS        libraries to pass to the linker, e.g. -l<library>
CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
            you have headers in a nonstandard directory <include dir>
CPP         C preprocessor
CXX         C++ compiler command
CXXFLAGS    C++ compiler flags
CXXCPP      C++ preprocessor
PKG_CONFIG  path to pkg-config utility
PKG_CONFIG_PATH
            directories to add to pkg-config's search path
PKG_CONFIG_LIBDIR
            path overriding pkg-config's built-in search path

The resulting compile command will be:

$CC -o conftest$ac_exeext $CFLAGS $CPPFLAGS $LDFLAGS conftest.$ac_ext $LIBS >&5

–whole-archive

–no-whole-archive

Like in dynamic linking (?) symbols in an archive are only linked when they are needed. So it's important to use the correct order libb, liba (where libb uses symboles in liba). To tell ld to link the whole archive one can use the –whole-archive libx liby –no-whole-archive ( or -Wl,-whole-archive and -Wl,-no-whole-archive when input to g++).

When passed to LDFLAGS this order is brocken –
