Hi, when setting up Context for my phone, I noticed the ARM binaries that come with the Standalone don’t work because the system is armv7l soft-float:
$ gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/lib/gcc/arm-linux-gnueabi/4.6/lto-wrapper
Target: arm-linux-gnueabi
Configured with: ../src/configure -v --with-pkgversion='Debian 4.6.3-14'

--with-float=soft --enable-checking=release --build=arm-linux-gnueabi
--host=arm-linux-gnueabi --target=arm-linux-gnueabi
Thread model: posix
gcc version 4.6.3 (Debian 4.6.3-14)
Since I’m supplying my own Luatex binary that’s no problem per
se, I just had to modify setuptex a bit.
Could we add a couple lines like the attached patch to the
script? I’m under the impression that “armel” is a Debian
specific term so feel free to change it. Though it might be
better in general to use the “arm-linux-gnueabi” and
“arm-linux-gnueabihf” triplets to separate the platforms.
Best,
Philipp
