Thanks again. I pointed CMake to the uppermost directory that contains the CMakeLists.txt file along with LICENSE.md, README.md, and SUPPORT.md. Now the configuration seems to start correctly:
-- Performing Test DEAL_II_HAVE_FLAG_Werror -- Performing Test DEAL_II_HAVE_FLAG_Werror - Success -- Performing Test DEAL_II_HAVE_FLAG_pedantic -- Performing Test DEAL_II_HAVE_FLAG_pedantic - Success -- Performing Test DEAL_II_HAVE_FLAG_Wall ... But then I get, for example: ... -- Performing Test DEAL_II_HAVE_AVX512 - Failed -- Performing Test DEAL_II_HAVE_ALTIVEC - Failed ... And finally: -- Looking for C++ include sys/resource.h - not found -- Looking for C++ include unistd.h - found -- Looking for gethostname - not found -- Looking for getpid - found CMake Error at cmake/checks/check_02_system_features.cmake:85 (message): Cygwin and forks such as MinGW and MinGW-64 are unsupported due to multiple unresolved miscompilation issues. Call Stack (most recent call first): cmake/macros/macro_verbose_include.cmake:18 (include) CMakeLists.txt:129 (verbose_include) -- Configuring incomplete, errors occurred! Any advice on how to solve this issue? thank you very much paolo Il giorno mar 2 set 2025 alle ore 20:33 Daniel Arndt <[email protected]> ha scritto: > Paolo, > > it doesn't matter where you create the. build directory (as long as > it's a subdirectory) but you need to point CMake to the uppermost > directory that has a CMakeLists.txt file (which should be the same as > the one containing LICENSE.md, README.md, and SUPPORT.md . > > Best, > Daniel > > On Tue, Sep 2, 2025 at 2:21 PM Paolo Tesini <[email protected]> > wrote: > > > > Thank you very much.
