Bug#912799: doxygen switch to llvm-toolchain-7
Hi, in preparation for this switch I am building doxygen from source with:
sudo apt install llvm-7-dev # for /usr/lib/llvm-7/lib/cmake/llvm/LLVMConfig.cmake
sudo apt install clang-7 # for /usr/lib/llvm-7/lib/cmake/clang/ClangConfig.cmake
git clone https://github.com/doxygen/doxygen
cd doxygen
mkdir build
cd build
LLVM_DIR=/usr/lib/llvm-7/lib/cmake/llvm/ Clang_DIR=/usr/lib/llvm-7/lib/cmake/clang/ cmake -Duse_libclang=ON -G "Unix Makefiles" ..
make
It builds, but the resulting binary fails to start with:
./bin/doxygen
: CommandLine Error: Option 'help-list' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
