I am unable to create a working executable file by running the make command in a tree previously built on an i386 machine. I'm getting an error message in the form of 

me@me-desktop:~$  make
/usr/bin/ld: i386 architecture of input file `../.. /Lib/libProgram.a(something.o)' is incompatible with i386:x86-64 output

I've been told and reassured that this program has been tested and successfully compiled on 64-bit Fedora.

I'm running a 64-bit machine

me@me-desktop:~$  uname -m
x86_64

I'm running Ubuntu 10.04

me@me-desktop:~$  lsb_release -a

Any clues as to what is going wrong?

    are you building from source - or are you linking against prebuilt object/library files? If the latter - are you sure these libraries/objects are actually 64bit?

  • Hi fossfreedom, sorry for the newb factor... I have no idea if these are linking against "prebuilt object/library files". There are no executable files that came with it. How do I determine if there are "prebuilt object/library files"?

There are a some possibilities:

  • need to run ./configure before make (if copied over from 386-machine)
  • need to run ./autogen.sh (if checked out from version control with no configure script given)

  • Thanks aquaherd, I can confirm this was copied from a 386-machine. I will try this out once I get access to my 64-bit ubuntu at home in like 4 hours.

    In this case, doing a make clean before ./configure would help. Also, if an autogen.sh is present, issuing make distclean may force the regeneration of the configure script for x86_64.
