dear sir, I have removed TestSuite/Sparse from my distribution and the compilation succeed. I am trying to use TAU but there is a lot of bugs in tcl/tk scripts. For example, the command "Open New Project" don't seem to do anything. When I execute TAU, a "PM_FAILED" message appears in the project box. A box appears and says: "Error in Tcl script: can't read PM_Globals(WorkingTools): no such element in array". All other tools (classy, ...) wants loading a project before execute them. thanks Sid Ahmed Ali TOUATI.
