'memcpy@GLIBC_2.4' error while jogl compilation

Hello!

I am trying to build Gluegen and Jogl at my i.mx6 armv6hf platform, as Sven Gothel recommended at the end of this post, but facing with 'memcpy@GLIBC_2.4' issue.

I digged a forum and found a couple of treads with the same issue, like this and this, but there are no solution.

There was a link to toolchain in one of those posts, but I couldn't figure out how to use it. I put "armhf-unknown-linux-gnueabi" directory to / and set TARGET_PLATFORM_LIBS=/armhf-unknown-linux-gnueabi/lib/gcc/armhf-unknown-linux-gnueabi, but got same "GLIBC2.4" error.

So, the question is how to build jogl with my existing toolchain:
gcc version 4.9.2 (GCC).
GNU C Library (GNU libc) stable release version 2.21.

Thank you.

The toolchain above is available here, check for x-tools*:
  <http://jogamp.org/files/toolchain/>

Above setup is documented in our jogamp-scripting repo,
which contains all startup/config files for our jenkins
build system and more:

- Above symlinks

Yes we should accommodate newer toolchains.

Please file a new bug report - thank you.
  - Add all info above into it, thx alot!
  - It will be one of the next work items.

Until then .. you may try the above description
of using our toolchain.

Thank you.

'armhf-unknown-linux-gnueabi' of course :)

'armsf' dropped in by accident (copy/paste), sorry.

Thank you for your help!
I successfully built gluegen and jogl.

Step-by-step guide:
1. Download opt-linux-armxx...tar.xz and unpack it into / (root dir)
2. Download x-tools and unpack it into /usr/local
3. Create directory /opt/toolchain/armhf-linux-gnueabi/bin/
4. Check symlinks in /opt/toolchain/armhf-linux-gnueabi/bin/ (create them if necessary)
5. export TOOLCHAIN_SYMLINKS=/opt (it may be unnecessary)
6. export PATH=$TOOLCHAIN_SYMLINKS/toolchain/armsf-linux-gnueabi/bin:$PATH
7. Go to ../gluegen(or jogl)/make  directory and type "sh ./scripts/make.gluegen.all.linux-arm6hf-cross.sh" or something like that.
