Hi,
I tried to build an image with the "expat" package in it, using a
toolchain without a C++ compiler. It fails with the following error:
configure: error: in `/home/dkc/src/buildroot/build/build/expat-2.2.4':
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
Enabling C++ support fixed that error.
It's weird because the C++ preprocessor is supposed to checked by the
AC_PROG_CXXCPP macro, which is not present in configure.ac, but maybe
that macro is implied with recent versions of autotools when using
AC_PROG_CXX?
Anyways, should "expat" depends on BR2_INSTALL_LIBSTDCP?
Thank you,
