Cscope build fails with error message "could not read symbols: File in wrong format"

Question

I am cross-compiling cscope, but suprised to be failed. However, I succeed to build ctags without error, so why does the cscope build fail?

The error message is as follows:

I think it's related to NASM. you can try to switch 64bit options. — Farshid Ashouri, Mar 02 '14 at 21:31

This could possibly be caused with old object files (for different target) from previous compilation. Try running make clean or equivalent for the package and try compiling again.

it's not the problem of make clean, why could not read symbols: File in wrong format? – thinke365 Sep 14 '12 at 19:25
@thinke365 I encountered the same error when I had .o files compiled for different target in the package directory. make clean should remove these and thus might help. – jhonkola Sep 15 '12 at 12:57

A make clean wasn't enough, I had initially set up my environment wrong. Once I fixed that, removed all the generated config/build file, reran the config with the correct toolchain(host, etc).. worked like a charm... – Begui Apr 01 '14 at 12:25

what was not set correctly in your environment, what caused the problem? – Black Aug 25 '15 at 14:19
