[ptxdist] error when compiling toolchain for arm-cortexa8

[ptxdist] error when compiling toolchain for arm-cortexa8

[Dr. Patrick Langfeld]

Hi,
We have a problem when compiling the arm-cortexa8 toolchain with 
ptxdist.
What we did is: 
download from 
http://www.pengutronix.de/software/ptxdist/download/ptxdist-2012.10.0.tar.bz2
unpacking
   tar -xf OSELAS.Toolchain-2011.11.3.tar.bz2
  changing into project dir OSELAS.Toolchain-2011.11.3 and creating a 
softlink with
     ln -s /usr/local/bin/ptxdist-2012.10.0 ptx
configuring and start build with
   ./ptx select 
ptxconfigs/arm-cortexa8-linux-gnueabi_gcc-4.6.2_glibc-2.14.1_binutils-2.21.1a_kernel-2.6.39-sanitized.ptxconfig
   ./ptx go --force


We got the following error:

new error: make[3]: Leaving directory 
`/home/delaitre/src/optimeas-ptxdist/toolchains/OSELAS.Toolchain-2011.11.3/platform-arm-cortexa8-linux-gnueabi-gcc-4.6.2-glibc-2.14.1-binutils-2.21.1a-kernel-2.6.39-sanitized/build-cross/gcc-linaro-4.6-2011.11-first-build/gcc'

Error 2

Any idea what went wrong?

Best regards

Don't do this. Always build the toolchain with the ptxdist version it was
configured for.

Make calls 'echo' with many absolute paths inside
gcc-linaro-4.6-2011.11-first-build. The resulting argument list is too long
for bash to handle. This is a known issue. You have two options:
1. Make sure the absolute paths are shorter by building e.g. in
/home/delaitre/src/OSELAS.Toolchain-2011.11.3/ (I think this is short
enough).
2. Use the new 2012.12.0 Toolchain. I've applied a patch that should fix
this.

Michael
