https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D252277 Bug ID: 252277 Summary: cmake find_package(python3...) fails to get default python version Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: ports-bugs@FreeBSD.org Reporter: FreeBSD@ShaneWare.Biz In older cmake versions, we would use find_package(PythonInterp 3.4 REQUIRED) find_package(PythonLibs 3.4 REQUIRED) with cmake >=3D 3.12 we can replace that with find_package(Python3 3.4 REQUIRED COMPONENTS Interpreter Development) The old method will find the python version matching the python version set= in DEFAULT_VERSIONS The newer python3 method always gets the largest python version installed, = not the default version. example using old method (CORRECT) - find_package(PythonLibs 3.4 REQUIRED) -- Found PythonLibs: /usr/local/lib/libpython3.7m.so (found suitable version "3.7.9", minimum required is "3.4")=20 change this to new method (WRONG) - find_package(Python3 3.4 REQUIRED COMPONENTS Interpreter Development) -- Found Python3: /usr/local/bin/python3.9 (found suitable version "3.9.0", minimum required is "3.4") found components: Interpreter Development Development.Module Development.Embed=20 The new way should find the same py3.7 This is using cmake 3.18.5 and still applies to 3.19.2 found in bug #251920 --=20 You are receiving this mail because: You are the assignee for the bug.=
