It's the sunrpc Makefile that's looking for BUILD_CC. Before I added the
configparms, the *only* compiles against a plain gcc were in the sunrpc
directory.
Looking at my output, I do see where cross-rpcgen is being run on the
local system. The code is building rpcgen and cross-rpcgen. I guess
that rpcgen should be built with cross-gcc and plain rpcgen with
${LFS_TGT}-gcc. That's done without any configparms file.
I'm starting to think that the problem is that we've built Chapter 6
glibc in 7.2 without the --enable-obsolete-rpc which would probably
solve the problem there. For a 7.1 host, we'd need a note to install
the rpcnis-headers.tar.bz2 tarball as a part of Chapter 5 glibc.
As in BLFS libtirpc:
if [ ! r /usr/include/rpc/rpc.h ]; then
tar -xvf ../rpcnis-headers.tar.bz2 -C /usr/include
fi
That's not something I want to do. Perhaps the workaround of the sed
for Chapter 5 is the way to go.
