Hi!

I would like to update my Raspberry Pi 1 NFS root.
I do it using
Code:
ROOT=/data/raspi_root armv6j-hardfloat-linux-gnueabi-emerge -DuNav @world

It works for a set of ebuilds, but some fail.

For example, sys-apps/file cannot find -lz.
Code:
configure:14418: checking for gzopen in -lz
configure:14443: armv6j-hardfloat-linux-gnueabi-gcc -o conftest -O2 -pipe -march=armv6j -mfpu=vfp -mfloat-abi=hard -fomit-frame-pointer  -Wl,-O1 -Wl,--as-needed conftest.c -lz   >&5
/usr/libexec/gcc/armv6j-hardfloat-linux-gnueabi/ld: cannot find -lz
collect2: error: ld returned 1 exit status


How can I tell cross-emerge where to find existing libs and headers?

[EDIT] => first I need to install all necessary libs in /usr/${CROSS-TARGET},

List of other failing builds
  • sys-apps/ncurses[cxx] : the g++ related variable is not resolved and points to absent program call (only arguments) bug 491422
  • sys-devel/gcc : same problem with empty ${CXX} expansion

You have installed zlib similarly to /data/raspi_root ? I don't know
how to tell that crossdev, but sys-apps/file should compile after
letting zlib install to /usr/armv6j-hardfloat-linux-gnueabi .

yeah, I will try it, first installing everything in /usr/arm*

EDIT: it works! Will give the list of the other failing builds in the first post (ncurses, ...)
