This one "CGAL/Arr_geometry_traits/Conic_x_monotone_arc_2.h:205:42: warning: bitwise operation between different enumeration types" is in Qt, not in CGAL.

This one "CGAL/Arr_geometry_traits/Conic_x_monotone_arc_2.h:205:42: warning: bitwise operation between different enumeration types" is in Qt, not in CGAL.

There are indeed similar warnings in Qt, but the CGAL warning is:

[afabri]

So let me apply a static_cast<int> before or-ing.

[lrineau]

The target variable this->_info is of type int, anyway.

[lrineau]

@danston I do not understand the deprecation warnings in Barycentric_coordinates_2. Are they false positives?

[danston]

@lrineau Yes. I tried to fix them but nothing helped. See here.

Another warning in Visual Studio:

https://github.com/CGAL/cgal/blob/master/Polygon_mesh_processing/include/CGAL/Polygon_mesh_processing/internal/Isotropic_remeshing/remesh_impl.h#L935

warning C4701: potentially uninitialized local variable 'deviation_post' used

Not initializing deviation_post in line 924 looks like it could cause undesired behavior.

Only the usage of an uninitialized variable is an undefined behavior. Here the initialization and usage of deviation_post is coupled to the condition !badly_shaped, and thus the code is correct. Can you please tell us:

• which version of CGAL you used to see that warning,
• which version of Visual Studio,
• and which compiler options?

@lrineau here are the steps to reproduce it on Visual Studio 2019, Windows 10

vcpkg install cgal

CMakeLists.txt

set(CMAKE_TOOLCHAIN_FILE $ENV{VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake)

cmake_minimum_required(VERSION 3.20)

project(example)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /W4 /WX")

find_package(CGAL REQUIRED)

add_executable(${PROJECT_NAME} main.cpp)

target_link_libraries(${PROJECT_NAME} PUBLIC CGAL::CGAL)

main.cpp

__pragma(warning(push,0))
#include "CGAL/Polygon_mesh_processing/remesh.h"
#include "CGAL/Surface_mesh.h"
__pragma(warning(pop))

int main() { 
    CGAL::Surface_mesh<CGAL::Exact_predicates_inexact_constructions_kernel::Point_3> mesh;

    double tar_len;

    CGAL::Polygon_mesh_processing::isotropic_remeshing(mesh.faces(), tar_len, mesh);

    return 0; 
}

This results in compilation error:

1>------ Build started: Project: example, Configuration: Debug x64 ------
1>main.cpp
1>C:\vcpkg\installed\x64-windows\include\CGAL\Polygon_mesh_processing\internal\Isotropic_remeshing\remesh_impl.h(942): error C2220: the following warning is treated as an error
1>C:\vcpkg\installed\x64-windows\include\CGAL\Polygon_mesh_processing\internal\Isotropic_remeshing\remesh_impl.h(942): warning C4701: potentially uninitialized local variable 'deviation_post' used
1>Done building project "example.vcxproj" -- FAILED.

This warning/error will go away if I modify line 924 to

int deviation_post;

to

int deviation_post = std::numeric_limits<int>::max();

Hi @jasjuang, now I understand. In the CGAL daily testsuite, we have several columns corresponding to Windows platforms, and on all of them we only use /W3, and /W4. That is why CGAL developers are not aware of warnings of level 4, like warning C4701: potentially uninitialized local variable. I will discuss with my colleagues, to decide if we want to support /W4 on Windows.

This issue is pretty old now. A new one should be created with the current warnings.
