           Summary: broken cross build environment / fix ncurses build
           Product: Openembedded

          Platform: Other
        OS/Version: Linux

While compiling ncurses on OpenSUSE 10.3 alpha, I got lower mentioned error
while installing ncurses.

The error comes from the problem, that at least for cross build OE uses broken
environment - it uses tools from staging/i686-linux/bin but does not include
staging/i686-linux/lib to LD_LIBRARY_PATH (for actual problem it calls tic from
staging with system ncurses library). It means, that it tries to use binaries
with different libraries they were compiled with.

It can cause undefined behavior, that's why I am marking it as major, however
fix can be trivial.

Work-around of this bug:
LD_LIBRARY_PATH=/path/to/OE/tmp/angstrom/staging/i686-linux/lib bitbake
angstrom-x11-image

Error message:
** Building terminfo database, please wait...
Running tic to install
/OE/build/tmp/angstrom/work/armv5te-angstrom-linux-gnueabi/ncurses-5.4-r8/image/usr/share/terminfo
.

        You may see messages regarding unknown capabilities, e.g., AX.
        These are extended terminal capabilities which can be compiled
        using
                tic -x
        Read the INSTALL document before doing this - it can cause
        problems for older ncurses applications.
