I'm crosscompiling dropbear. CHOST="arm-softfloat-linux-uclibc" CFLAGS="-march=armv4 -mtune=strongarm1100 -msoft-float" CXXFLAGS=${CFLAGS} ROOT=/mnt/yopi INSTALL_MASK="*.h" emerge -O cross-arm-softfloat-linux-uclibc/dropbear Everything went ok so far. So my yopi is actually already running some gentoo stuff. But dropbear is a little bugger. The configuration script of dropbear checks if the programs can be executed. Needless to say... amd64 ain't going to run arm code ;) As I see in here --host it is amd64. What am I doing wrong here :) configure:1647: arm-softfloat-linux-uclibc-gcc -V </dev/null >&5 arm-softfloat-linux-uclibc-gcc: `-V' option must have argument configure:1650: $? = 1 configure:1673: checking for C compiler default output file name configure:1676: arm-softfloat-linux-uclibc-gcc -march=armv4 -mtune=strongarm1100 -msoft-float conftest.c >&5 configure:1679: $? = 0 configure:1725: result: a.out configure:1730: checking whether the C compiler works configure:1736: ./a.out ./configure: line 1737: ./a.out: cannot execute binary file configure:1739: $? = 126 configure:1748: error: cannot run C compiled programs.

you didnt set CBUILD nor did you post `emerge info` or the output of `emerge dropbear`
http://dev.gentoo.org/~vapier/CROSS-COMPILE-HOWTO - you should also set CBUILD to your building machine for completeness sake ... most of the time you won't need it, but sometimes you will :) That line is quite important for every configure based program.

you're really way beyond the scope of bugzilla here if you have cross-compiling questions, seek help on the embedded mailing list and/or irc channel
(In reply to comment #5) > you're really way beyond the scope of bugzilla here > > if you have cross-compiling questions, seek help on the embedded mailing list > and/or irc channel The issues is not that I can't fix it in a LFS way. But I can't fix it in a Gentoo way. The primary reason I moved away from LFS was maintainability, the abstraction portage provides. The configure script of binutils must be not getting the arguments from the first script. And the ebuild of uclibc must be untested with minimal. I think these two issues are well inside the scope of bugzilla, and could be filled serperately but I don't want to bug people any more than you want to answer them.
