[aspect-devel] [deal.II] Re: deal.ii problem during aspect compile, static libs

Thorsten,

I got an error similar to this one before:

using -fPIE and -pie did not help. On the system I was using, Trilinos 
was compiled both as static library and as dynamic library. Now the 
problem is that cmake reads all the flags it needs for Trilinos from a 
file called TrilinosConfig.cmake. In this file, they are references to 
others libraries which in my case were dynamic libraries. When you use a 
static build, cmake will use a static library over a dynamic library if 
both exist, this caused the conflict in my case. The problem is when you 
compile deal.II but it doesn't appear until you try to create an 
executable. So you should check in the file detailed.log that you are 
not using any shared library.

Best,

Bruno
