Created attachment 338758 [details] emerge --info a recent upgrade of the system caused builds for vtk (both 5.10.0 and 5.10.1) to fail with the following error (v5.10.1 given as example, but both version produce the same error): ========== CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: R_LIBRARY_BASE linked by target "vtkGraphics" in directory /var/tmp/portage/sci-libs/vtk-5.10.1/work/VTK5.10.1/Graphics linked by target "vtkGraphics" in directory /var/tmp/portage/sci-libs/vtk-5.10.1/work/VTK5.10.1/Graphics ========== Looking on the net I find the following possible explination <http://vtk.org/Bug/bug_relationship_graph.php?bug_id=10779&graph=relation>: "...the[re] is no libR{lapack,blas}.so anmore, but everything is included in libRmath.so..." with notes for a patch they use on Gentoo. I have not had time to track down, integrate, and test the patch.
Please attach the entire build log to this bug report.
Comment on attachment 338758 [details] emerge --info The build log is "required" too.
Created attachment 338954 [details] full build log sorry about the dalay and not including the build log.
The problem turned out to be a subtle issue with an R update. The details can be found here: https://bugs.gentoo.org/show_bug.cgi?id=457064 I was able to build sci-libs/vtk-5.10.0
