Compiling the latest version of usermode-sources fails with either the defaults in menuconfig or with similar settings I have used for earlier versions. emerge --info results below. Also, it would be nice to have a usermode-host-sources, for which I will submit an ebuild as a seperate bug. Reproducible: Always Steps to Reproduce: 1. emerge sync; emerge usermode-sources 2. make menuconfig ARCH=um [use the defaults, exit and save]; make dep ARCH=um 3. make linux ARCH=um I noticed the make dep step was not in the http://www.gentoo.org/doc/en/uml.xml instructions but omitting that step did not make a difference.

Does usermode-sources-2.4.26 have this issue?

It seems there are quite a few compilation issues with this patchset, unfortunately they appear to be upstream issues. Making bug 49277 the place to monitor any progress. *** This bug has been marked as a duplicate of 49277 ***
