Thanks for pointing this out. When I started cross building, I briefly looked at these and immediately skipped them, because they looked way out of date. I'm sorry, if this decision was flawed. I'm not sure why you refer to gcc-4.8 as the jessie compiler when most of the archive is built with gcc-4.9. I assume that this is a mistake and will correct the url to http://sources.debian.net/src/gcc-4.9/4.9.2-2/debian/README.cross/. So let me reexamine: * emdebian refers to squeeze toolchains. * "http://zigzag.lvk.cs.msu.su/~nikita/debian/"; The domain name no longer exists. * Then it mysteriously talks about a "toolchain-source" approach I've never heard off and refers to gcc versions between 3.3 and 4.3. I guess I can skip this part as it feels more like a history lesson. * In section 1.3 it tells me that I need to download a libc for my target. So at least bootstraps appear to be unsupported by the default method (according to the documentation). * Section 2 explains to build cross compilers by setting GCC_TARGET. As of dpkg version 1.17.17 this variable is no longer honoured. What is being built here is a native compiler. My conclusion is that the reference to this documentation is a straw man. The process described therein does not cover relevant cases and does not work either. On the other hand, the unsupported method has been working for me. I'd be happy to help fixing this, but I lack an understanding of how the default method is supposed to work. So I think I've done what I can do by pointing out what is wrong. Should I open a bug against gcc-4.9? Dimitri, it seems to me that your perception of reality is skewed. Your assuming that the default method was working for everyone does not match my reading of this bug log. I have the impression that you are trying to deny the usefulness of the alternate method. It feels roughly equivalent to (hypothetical) systemd proponents denying the usefulness of sysvinit by arguing that sysvinit is broken while at the same time it works for many. It is my understanding that we don't intentionally break stuff unless there is reason to do so. Please, can we rather work on making the default work for everyone and keep the non-default available until a significant amount of users is able to switch?
