ldd.host bug (32 vs. 64 bit)

[Oliver Metz]

Hi all.

Almost 2 years passed by when I sent the below mail to this list. Unfortunately no one has responded. But ldd is still broken when cross-compiling for a different architecture (32 vs. 64 bit). As a workaround we use "-m32" in the Freetz Project to build the utils [1]. Unfortunately I don't have the knowledge to fix this. So help is appreciated.

Regards
Oliver

Hi,
I'm building a mipsel uclibc (0.9.31) toolchain (32-bit) on 64-bit Ubuntu. When trying to analyze a mipsel binary with ldd.host it fails with: "...not an ELF file."

This is caused by the following test in http://git.uclibc.org/uClibc/tree/utils/ldd.c#n220: 
|| ehdr->e_ident[EI_CLASS] != ELFCLASSM

The first expression evaluates to ELFCLASS32 and the second one is defined as ELFCLASS64. Commenting out the check doesn't help because then it's throwing a segfault.

Can anybody confirm this bug? Or even fix it? Should I open a ticket on bugzilla?

Regards
Oliver
