Hi Dave,
It works if I run, "make is_build_tool=yes tools-install" in .../build-root
but if I specify the platform, I still see the same issue if I try to
cross-compile tools with make PLATFORM=x86_64 TAG=x86_64_debug
is_build_tool=yes tools-install
It is hitting this configuration in ../src/configure.ac
AM_COND_IF([CROSSCOMPILE],
[
AC_PATH_PROG([VPPAPIGEN], [vppapigen], [no])
if test "$VPPAPIGEN" = "no"; then
AC_MSG_ERROR([Externaly built vppapigen is needed when
cross-compiling...])
fi
