How to solve error “o rule to make target”?

Question

This Error pops up while I try to Compile the Project Map of Cartotype, I followed The Instruction on The Cartotype Documentation, but at this point I couldn't do any progress, help please !

:-1: error: No rule to make target 'G:/QT/Projects/cartotype-eval/CartoType-Public/src/apps/Maps/../../../../cartotype_windows_sdk_evaluation_5.10.7/CartoType/bin/15.0/x64/DebugDLL/libcartotyped.a', needed by 'debug/CartoTypeMaps.exe'.  Stop.

My colleage tested same project on QT Linux - Ubuntu, and it worked smoothly !

I presume that you're using MinGW since the buildtool is looking for foo.a . You need to simply look at that error and understand what it means: a library it needs is missing. Until you provide that library, it won't build. That's the simple part. The hard part is that according to the SDK overview , CartoType comes with .lib libraries only, not .a libraries. But modern MinGW supports .lib files, so you only need to convince it to look for the .lib file, not .a file. Most likely, your build scripts have the reference to .a , or no full filename whatsoever.

If you're using QMAKE, you likely have something like:

LIBS += -LX:/cartotype_windows_sdk_evaluation_5.10.7/CartoType/bin/15.0/x64/DebugDLL cartotyped

Instead, you'd want:

LIBS += X:/cartotype_windows_sdk_evaluation_5.10.7/CartoType/bin/15.0/x64/DebugDLL/cartotyped.lib
