Osrm-backend: Cannot build due to "No CMAKE_CXX_COMPILER could be found."

[vinci1it2000]

While trying to follow the procedure for building OSRM under Windows,
I get the following error from the build-script:

deleting build dir...

Note that I have installed a more recent cmake so I had to force the script to accept using cmake-3.7.2 instead of 3.7.1.
Could this be the problem?

Looks like CMake can't find a C++ compiler on your Windows system.

Are you sure there is one installed?

[vinci1it2000]

Yes I have MinGW.

[daniel-j-h]

Try to pass

-DCMAKE_C_COMPILER="C:/MinGW/bin/gcc" -DCMAKE_CXX_COMPILER="C:/MinGW/bin/g++"

(or where ever you have the binaries installed) to cmake.

Now I have another error:

Looks like we should be quoting some things in our CMakeLists.txt file. However, your system is still failing to set ${CMAKE_CXX_COMPILER_ID}, which is not good.

@vinci1it2000 Can you please edit CMakeLists.txt and put quotes around anywhere you see ${VARIABLE} used, then try again?

[daniel-j-h]

Closing this as not actionable on our side. Unfortunately we're not using Windows for development.

You have to figure out how to make CMake recognize your compiler.

please reinstall cmake

[santiagodemierre]

sudo apt install g++
