I have got the impression that there is a 64 bit compatibility problem. Can it be solved with autoconf macros in your project?
Hi Markus,
you are not saying which version of the PPL you are trying to compile. From the path "~/Projekte/PPL/trunk" I guess you are using a version that, at some stage, was the HEAD of the master branch in the central Git repository. If that is the case, what you observe can be explained by the use of an old version of Libtool. So:
1) if you really want to stay on the bleeding edge, using the Git versions, try updating Libtool to the latest available version; 2) otherwise, download an official ppl-0.10.2 tarball and try with that one.
Notice also that:
a) --enable-optimization is the default; b) --enable-pch did not receive much testing since when we realized that it does not speed up building the library in a significant way.
All the best,
Roberto
