It's hard to tell what the real issue is. But, you'd get this kind of error if the binary being relocated is corrupt. The script reads the ELF header first and then goes through the program header table to find the INTERP section. Apparently, in your case, the size of e_phentsize (which is taken from the ELF header) is different from the actual size of one program header entry for a 32bit binary.
But, you could easily find out which is the problematic binary: 1. Run the SDK installer with -S -R 2. go to the install directory and change the relocate_sdk.py to print the name of the binary being relocated 3. execute ./relocate_sdk.sh After you find the binary, use readelf to inspect it. > > > Could you please point me to a forum where I can ask for help_ You can always find help on the OE-core mailing list: [email protected] (CCed) You can subscribe here: http://lists.openembedded.org/mailman/listinfo/openembedded-core laurentiu > > > Thanks in advance, > > Wilder > > > -- _______________________________________________ Openembedded-core mailing list [email protected] http://lists.openembedded.org/mailman/listinfo/openembedded-core
