CGAL users discussion list

[Alex Tsui <>]

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:
