Yes. BTW, the LD_PRELOAD description in the ld.so(8) man page should also be improved to know what happens in case of all kinds of errors. > > Perhaps in the long term, ld.so should provide a way to avoid > > error messages due to non-matching permissions or ELF class. > > Yes.

Yes, if the program is executed, one should have a way to silent ld.so, whatever the reason for which a clear decision can be made. An error message + failure would be useful only in case of real error (e.g. I/O error on some directory in the library search path). > > Perhaps provide a 32-bit library for the amd64 package?

Unfortunately, this is not a perfect solution since ARM doesn't seem to have multilib: the dependencies on https://packages.debian.org/sid/gcc-5-multilib can give an idea for the various architectures. -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
