Hello Taylor, Thank you for the help! When I input ./configure --enable-cross-compiling --enable-native-code=svm1-32le
The configure fails at step "checking for native-code support" with the error "configure: error: unknown compiler architecture: svm1-32le". I downloaded the mit-scheme-10.1.10-svm1.tar.gz package on my desktop linux to run this build. From fiddling around with this build system, I know it is checking the config.sub file for known architectures. Should I add anything to this file to make it recognize the svm1-32le argument? -kit On Thu, Apr 30, 2020 at 11:12 PM Taylor R Campbell <campb...@mumble.net> wrote: > > Date: Thu, 30 Apr 2020 22:52:57 -0400 > > From: James Flaherty <kitcat425....@gmail.com> > > > > In short, I'm trying to run MIT-scheme on an odroid xu4 running arch > linux > > arm running linux kernel armv7l 4.14.176-1.
