CGAL users discussion list

[Qingnan Zhou <>]

Hi Adam,

Have you tried this?

cmake -DCGAL_DONT_OVERRIDE_CMAKE_FLAGS=TRUE -DCMAKE_BUILD_TYPE=Debug ..

CGAL's UseCGAL.cmake script overwrite the flags $CMAKE_BUILD_TYPE and $CMAKE_CXX_FLAGS with $CGAL_BUILD_TYPE and $CGAL_CXX_FLAGS which is set when CGAL was compiled (in your case it is set when you install CGAL from homebrew).  See section 15.4 of the manual.

best,

James

The homebrew script is set to compile in Release mode, and so it seems that it will switch your build type to Release regardless of what you set it. I tried building a test project in Release mode and linking to a CGAL built in Debug mode and it did the opposite - it was switched to Debug mode.

Maybe try to fetch CGAL and build it yourself in Debug mode? Then export CGAL_DIR=/path/to/your/cgal and try rebuilding your project.

What's your CGAL_DIR? Did you build CGAL from source with CMAKE_BUILD_TYPE=Debug?

Hello all,

No matter that I set -DCMAKE_BUILD_TYPE=Debug, I always get a Release build:

According to the cmake list, one of CGALs find_package modules is setting the CMAKE_BUILD_TYPE, though I have been unable to verify this.

The only workaround I've found is to build twice, e.g. the script scan-build.sh is:

#! /bin/bash

rm -rf build/

mkdir build

cd build

cmake -G Ninja -DCMAKE_C_COMPILER=/usr/local/Cellar/llvm/3.5.1/share/clang/tools/scan-build/ccc-analyzer -DCMAKE_CXX_COMPILER=/usr/local/Cellar/llvm/3.5.1/share/clang/tools/scan-build/c++-analyzer ..

cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug ..

/usr/local/opt/llvm/bin/scan-build -o $(pwd)/scanresults -v ninja

Which results in:
