gcc fails when I extract my SDK to another place than /usr/local.

Output when it fails:

$ ./arm-angstrom-linux-gnueabi-gcc
bash: ./arm-angstrom-linux-gnueabi-gcc: No such file or directory

Readelf output:

$ readelf -d arm-angstrom-linux-gnueabi-gcc

Dynamic section at offset 0x34394 contains 21 entries:
Tag Type Name/Value
0x00000001 (NEEDED) Shared library: [libc.so.6]
0x0000000f (RPATH) Library rpath:
[/usr/local/angstrom-eglibc-i686-armv7a/sysroots/i686-angstromsdk-linux/usr/lib/armv7a-angstrom-linux-gnueabi:/usr/local/angstrom-eglibc-i686-armv7a/sysroots/i686-angstromsdk-linux/lib]

Is it the RPATH here that's making trouble for me?

Not exactly. And RPATH is needed to find some of the shared libraries that are needed. I thought we had been running chrpath over these to make them relocatable, however.

Does this RPATH indicate that its not relocatable? Anything else I can check?

It should be using RUN_PATH $ORIGIN to relocate itself based on the initial run-time location.

It sounds like something is not being run as it should for the SDK component(s).

it should come by inheriting relocatable class I think and this class is being inherited in cross|native|nativesdk classes.
