Hi, the problem is solved. Echo.lo was an empty file, probably left empty due to a lack of RAM. The problem was fixed by removing such files. Bitbake then successfully recreated them with the right content. Regards Paul Von: Paul Sievers [mailto:p.sievers@ms-ag.de] Gesendet: Mittwoch, 6.

I ran "bitbake meta-toolchain" on Linux in a VirtualBox with 3 GB RAM and ran into the following problem: | x86_64-linux-libtool: error: 'echo.lo' is not a valid libtool object | make[4]: *** [librpmio.la] Error 1 | make[4]: Leaving directory `/home/paul/fsl-release-bsp/evk/tmp/work/x86_64-linux/rpm-native/5.4.16-r0/b uild/rpmio' | make[3]: *** [all-recursive] Error 1 | make[3]: Leaving directory `/home/paul/fsl-release-bsp/evk/tmp/work/x86_64-linux/rpm-native/5.4.16-r0/b uild/rpmio' | make[2]: *** [all] Error 2 | make[2]: Leaving directory `/home/paul/fsl-release-bsp/evk/tmp/work/x86_64-linux/rpm-native/5.4.16-r0/b uild/rpmio' | make[1]: *** [all-recursive] Error 1 | make[1]: Leaving directory `/home/paul/fsl-release-bsp/evk/tmp/work/x86_64-linux/rpm-native/5.4.16-r0/b uild' | make: *** [all] Error 2 | WARNING: exit code 1 from a shell command. | ERROR: oe_runmake failed | ERROR: Function failed: do_compile (log file is located at /home/paul/fsl-release-bsp/evk/tmp/work/x86_64-linux/rpm-native/5.4.16-r0/te mp/log.do_compile.2340) ERROR: Task 38 (virtual:native:/home/paul/fsl-release-bsp/sources/poky/meta/recipes-devtool s/rpm/rpm_5.4.16.bb, do_compile) failed with exit code '1' NOTE: Tasks Summary: Attempted 369 tasks of which 367 didn't need to be rerun and 1 failed.
