[ptxdist] Using Crosstool-ng Toolchain with PTXDIST

[ptxdist] Using Crosstool-ng Toolchain with PTXDIST

Hi,

I'm currently trying to use a toolchain that I have compiled with
crosstool-ng with ptxdist-2011-07-0 however I have been having some problems
with ptxdist trying to recognize and use this toolchain.

The first problem that I have had is with the following ptxdist script:
script/lib/ptxd_make_00-init.sh. It gives me the following error:

"ptxdist: error: failed to source lib:
/opt/lib/ptxdist-2011.07.0/scripts//lib/ptxd_make_00-init.sh."

I have tracked down where this error is coming from and it is on 65 of the
ptxd_make_00-init.sh because of the sed call that looks for the collect2
folder. There isn't a collect2 folder in the toolchain that was compiled. So
to overcome that error I have made a temporary work around by just setting
the sysroot folder manually.

However, this has led to another problem, when trying to compile I get the
following error:

arm-cortex_a8_linaro4.5-linux-gnueabi-ld: /lib/libc.so.6: version
`GLIBC_2.7' not found (required by arm-cortex_a8_linaro4.5-linux-gnueabi-ld)

It seems that ptxdist or something is trying to use the host machine's GLIBC
instead of the cross compiler's sysroot even though I have manually
specified it.

Could somebody please point me to how I can compile a toolchain with
crosstool-ng that can be used with ptxdist? Or point me in the right
direction in how I can fix these errors?

Thanks,
-Ryan

Update your distribution, you need atleast GLIBC_2.7 to run the
toolchain. Is that toolchain compiled on that host?

Nope - It's about executing the toolchain's linker.

Updated GLIBC on the host machine to a version greater than 2.7 fixed that
error with the toolchain. However, the issue still exists
where ptxdist can't find the sysroot for the toolchain unless I manually
modify the ptxd_make_00-init.sh. What is the reason for searching for the
collect2 folder in order to determine the sysroot folder and isn't there a
better way to look for the sysroot folder?
