Usermode-sources compiles without a hitch. make menuconfig ARCH=um works as well. However, make linux ARCH=um fails quite loudly after the line: HOSTCC arch/um/util/mk_constants_kern.o It seems that whatever libraries make is directed to either do not exist or are terribly corrupted. Every problem has to do with a .h file Reproducible: Always Steps to Reproduce: 1. Emerge usermode-sources 2. cd /usr/src/linux 3. make menuconfig ARCH=um (save configuration as normal) 4. make linux ARCH=um Actual Results: Look in the "Additional Information" section. You'll get an idea of the ugliness. Expected Results: Compiled without a hitch and given me a user-mode kernel. This is the full output, from command call to exit.

[arch/um/util/mk_constants_kern.o] Error 1 make: *** [arch/um/util] Error 2 I'm bewildered. I also tried emerging vanilla-sources and performing the same task (make menuconfig ARCH=um, make linux ARCH=um) with the exact same failure. Something is terribly wrong here. People with compilers below the grade of 3.4.4 (I think someone was successful with 3.3.5, or something along those lines) do not seem to have such problems.
Which usermode-sources version are you using? I'm also confused the way you contradict yourself... "Usermode-sources compiles without a hitch." ... "However, make linux ARCH=um fails quite loudly" Isn't that the compilation process, or am I missing something?
Sorry, that's my error. The first line should read, "Usermode-sources EMERGES without a hitch." So, emerge usermode-sources works well, but make linux ARCH=um does not. The version of usermode-linux emerged is 2.6.12, which I believe is the latest one.
Please try usermode-sources-2.6.12-r1.
Please reopen when you have tested the latest version (currently usermode-sources-2.6.12-r1)
