Hi Dan and Bruno,
I have followed the thread 9117 for solving this problem, by adding
the recommended flag:
IF(${CMAKE_VERSION} VERSION_GREATER_EQUAL "3.16.0")
LIST(TRANSFORM CMAKE_THREAD_LIBS_INIT PREPEND "-l")
ENDIF()
which is what I understood from thread 9117 (which btw is not very well
written).
But I have not succeeded in compiling. The errors posted are similar:
-- Performing Test DEAL_II_HAVE_FLAG_Wplacement_new - Failed
When reading the file 'configure_1_threads.cmake' I found inside my
directory dealii-9.0.0/cmake/configure
..
I wonder where exactly I should add the corresponding
3-lines-instruction flag. I tried two target places inside the script, the
two that seemed to me as relevant and appropriate.. which are right below
the 'ADD FLAGS' locations..
I attach the virgin version of 'configure_1_threads.cmake'.
what should I do?
Am I interpreting thread 9117 correctly?
Am I adding the flags where they should be?
Is dealii 9.0.0 good for the purpose?
cheers,
Felipe
