The HowToBuild.html unfortunately only cover GNU Linux x86, 32- and
64-bit, this document needs to be updated to also cover ARM 32bit builds.

ARM builds can be performed using cross compilation and native compilation.

in both cases the system environment variable TARGET_PLATFORM_ROOT has to
be set and point to the root location of your arm system before running ant
if you compile directly on your iMX6 board TARGET_PLATFORM_ROOT shall be
set to / this is done by running the following command.
export TARGET_PLATFORM_ROOT=/

The jogamp team uses the build scripts
gluegen/make/scripts/make.gluegen.all.linux-armv6hf.sh
jogl/make/scripts/make.jogl.all.linux-armv6hf.sh
found inside the make directory to perform native builds

the following two scripts
gluegen/make/scripts/make.gluegen.all.linux-armv6hf-cross.sh
jogl/make/scripts/make.jogl.all.linux-armv6hf-cross.sh
to perform cross compile builds.

Run the scripts from inside the gluegen make directory
cd gluegen/make
sh scripts/make.gluegen.all.linux-armv6hf.sh

and similar from inside the jogl make directory
cd jogl/make
sh scripts/make.jogl.all.linux-armv6hf.sh

TARGET_PLATFORM_ROOT will be set correctly by the script and your build will succeed.

good luck!



The prebuilt armv6hf natives provided by jogamp shall work on your armv7hf system

Cheers
