Bug 193904 – app-misc/screen-4.0.3 fails to crosscompile with g-e armeb-softfloat-linux-uclibc due to configure error

• Product: Gentoo Linux
• Status: VERIFIED DUPLICATE

[Description Jason Cooper 2007-09-26 19:45:19 UTC]

While building a rootfs for my nslu2 project (using crossdev/xmerge) I found a build failure in app-misc/screen-4.0.3.  The following built successfully using the armeb-... toolchain: uclibc ($SYSROOT != $ROOT), busybox, zlib, openssl, openssh, cracklib, shadow, openssh, db, ncurses.

### The error ###
...
checking how to run the C preprocessor... armeb-softfloat-linux-uclibc-gcc -E
checking for grep that handles long lines and -e... /bin/grep
checking for egrep... /bin/grep -E
checking whether armeb-softfloat-linux-uclibc-gcc needs -traditional... no
checking for library containing strerror... none required
configure: error: cannot run test program while cross compiling
See `config.log' for more details.

...
### End of error ###

Most of the results returned by google basically bypass the configure script by making a 'config.cache' file with the proper key=value pairs defined in it.  This doesn't seem like a proper solution.  I think the appropriate solution is to fix the configure scripts to detect a crosscompile build and bypass the tests.  

With that being said, I will work on a patch to screen's configure scripts.  In the mean time, does this mean no one has ever crosscompiled screen?  Am I missing something?

thx

Reproducible: Always

Steps to Reproduce:
1.xmerge --root /path/to/rootfs -av app-misc/screen
