I think this page is obsolete. I add few commet since I tried to compile OSMR recently using Codeblocks 20.03 on Windows 10. What I found was that

Several extra libraries ave to be installed like BZip2, lua. I was using MSYS2 so I did, pacman -S mingw-w64-x86_64-bzip2 pacman -S mingw-w64-x86_64-lua pacman -S mingw-w64-x86_64-zlib

instal Intell tbb https://github.com/oneapi-src/oneTBB/releases Extract it to a folder (e.g., C:\tbb).

Ensure to add TBB Path to CMake Command and that the bin folder of MinGW or MSYS2 (e.g., C:\msys64\mingw64\bin) is added to your system PATH environment variable.

Then in osrm-backend\build run

cmake -G "CodeBlocks - MinGW Makefiles" .. -DCMAKE_BUILD_TYPE=Release -DTBB_INCLUDE_DIR="C:/tbb/include" -DTBB_LIBRARY="C:/tbb/lib/intel64/gcc4.8/libtbb.so"

cmake -G "CodeBlocks - MinGW Makefiles" .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS="-fno-lto -mconsole" -DCMAKE_EXE_LINKER_FLAGS="-Wl,-e,mainCRTStartup"

It may be enough to compile.

However for some compilation problems I add to do

  • remove "-Werror # Treat all warnings like error" in a CMakeLists.txt file
  • add in shared_memory.hcp in line 208: (void)lock_file; // This explicitly marks lock_file as used to avoid warning of unused variable
  • to avoid an Link Time Optimization (LTO) error run cmake -G "CodeBlocks - MinGW Makefiles" .. -DCMAKE_BUILD_TYPE=Release -DIPO=OFF
  • put OFF in option(ENABLE_LTO "Use Link Time Optimisation" OFF) and I add set(CMAKE_INTERPROCEDURAL_OPTIMIZATION OFF) in Cmake

I finally gave up because of Windows console incompatibility (Winmain not found) without knowing the reason even after having, In codebleocks Project properties, Built target, type put Console application
