Does this work for everyone else or is it just deprecated and nobody 
should use it?

I can't build without -lm neither in BR nor using my native host tools.

Thanks,
Val.

Which version of binutils are you using? 2.22?

I believe this is caused by an issue with linking indirectly with the
newer binutils. gqview relies on a library that is linked against libm
but does not explicitly link against libm itself. Before 2.22 binutils
would copy the DT_NEEDED entries from the library into gqview but it
does not do this any more.

A number of packages are affected by this. I believe the correct fix
is to modify the affected packages to link against the libraries they
use explicitly.

gqview calls pow() and sqrt() directly, though it doesn't link against libm.

Is the above patch OK?

Or do you mean configure/makefile(.in) should be patched to add libm 
dependency?

Thanks,
Val.

I think so, although it could do with a comment to say why it is
needed. Peter or Thomas may disagree though?

That is the proper long term fix that should be pushed to gqview upstream.

I thought it was kind of obvious.

Gqview is no longer supported. There's a Geeqie project that has been 
forked from gqview and is currently active.

I still use gqview since it has all the features I need and is smaller 
than geeqie. I also prefer gqview because it opens a window and shows
a "broken image" icon for unsupported image types, while geeqie doesn't 
create any window (even an error message box), which is a bit confusing.

Thanks,
Val.

  Problem can be reproduced on e.g. x86_64 with external toolchain.

  And since upstream is dead, the simple addition of -lm to LIBS is an
adequate solution.
