It should actually probably be just gcc or cc. i486-linux-gnu-gcc is how a cross-compiler would be called. See the discussion on debian-devel some months back: http://lists.debian.org/debian-devel/2007/11/msg00151.html Steve Langasek <vor...@debian.org> wrote: "There *is* a need to specify --build when not cross-compiling, if your upstream build rules do clever things when the architecture is detected as "i686" instead of "i386". This was the point in my previous comment. There is no need to specify --host when not cross-compiling, and specifying it will result in autoconf believing that the compiler should be invoked as a cross-compiler. Sometimes this has strange side effects as well." The issue here is that --host should only be passed when cross-compiling and --build should be passed alone in a native build. > I am not sure, but I think (see > /usr/share/doc/autotools-dev/README.Debian.gz) you are invoking > ./configure the wrong way. This makes it build successfully for me: Slight tweak, needed. See: http://wiki.debian.org/EmdebianGuide DEB_HOST_GNU_TYPE=$(shell dpkg-architecture -qDEB_HOST_GNU_TYPE) DEB_BUILD_GNU_TYPE=$(shell dpkg-architecture -qDEB_BUILD_GNU_TYPE) ifneq ($(DEB_HOST_GNU_TYPE),$(DEB_BUILD_GNU_TYPE)) CONF_ARGS= --build $(DEB_BUILD_GNU_TYPE) --host $(DEB_HOST_GNU_TYPE) else CONF_ARGS= --build $(DEB_BUILD_GNU_TYPE) endif The actual variable name you use is at your discretion, the point is that it only contains '--build $(DEB_BUILD_GNU_TYPE)' unless cross-compiling when it also adds the relevant --host entry.
