The following issue has been SUBMITTED. ====================================================================== https://public.kitware.com/Bug/view.php?id=16112 ====================================================================== Reported By: Gert Wollny Assigned To: ====================================================================== Project: CMake Issue ID: 16112 Category: CMake Reproducibility: have not tried Severity: minor Priority: normal Status: new ====================================================================== Date Submitted: 2016-05-26 05:03 EDT Last Modified: 2016-05-26 05:03 EDT ====================================================================== Summary: "uname -p" is a very poor choice to evaluate the CMAKE_*SYSTEM_PROCESSOR and may even be wrong Description: When running cmake in a i386 user space on top of an amd64 kernel the reported processor type may be X86_64 instead of i386, as it so happens with DCMTK as shown by the reproducible build effort:
https://tests.reproducible-builds.org/rb-pkg/testing/i386/dcmtk.html In the case of DCMTK this is of no serious consequence, but other projects might use this value for compile time decisions that could result in code that can not actually be run on the selected target architecture. Additional Information: For a further discussion see also: https://stackoverflow.com/questions/11944060/how-to-detect-target-architecture-using-cmake There is also a link to code that might be used to estimate the host arch based on try_compile. best, Gert ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2016-05-26 05:03 Gert Wollny New Issue ====================================================================== -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
