g++ and ld 4.1 for QuantLib: build speed, or lack thereof

[Dirk Eddelbuettel]

QuantLib'ers,

Did anybody notice that build times seem to have increased quite a bit under
gcc/g++/binutils 4.1?  I am trying to update RQuantLib and the final link
step [ for the comparatively small RQuantLib ] alone is running five or more
minutes on my home development machine (which us is a few years old, but has
plenty of ram).

Are there any known shortcuts, other than 'downgrade to g++ 4.0 or earlier' ?

It also appears that the gcc/g++ bug we noticed on hppa following the QL
0.3.13 release is now present in Debian testing. Until that bug is fixed I
can't even build RQL on testing, see below for the link errors.  Luckily, the
problem is fixed in unstable and g++ upstream, but I can't currently install
the Debian unstable toolchain on testing (due to conflicts with other
packages which we'll need to sort out first).

Thanks, Dirk

I get a similar problem when compiling QuantLibAddin - the final link
takes several times longer than it used to.

I'm not aware of a solution but if you discover one I'd love to hear about it.
