CMake - Undefined Reference

由 不问归期 提交于 2021-02-10 06:42:46
问题 I am trying to include gtest to my project. The problem is that I get a undefined reference error in the GTest. I am trying to test the Node class in Gtest. Inside the constructor of the Node I am using the Class Logger. Although I have added the library logger to the gtest-target I still the undefined reference error regarding to the Logger.... My guess CMake does no look for nested classes that are used inside Node. only Node itself. Temperoy fix If I use the Logger in the gtest-node.cpp it

How do you handle recursive dependencies in CMake

由 不打扰是莪最后的温柔 提交于 2021-02-09 20:30:36
问题 Say I have packages A, B, and C. Package B uses package A and package C uses package B. I create shared libraries. So in package B I do something like find_package(A) ... if(${A_FOUND}) target_link_libraries(B ${A_LIBRARIES}) endif() and in package C I do find_package(B) ... if(${B_FOUND}) target_link_libraries(C ${B_LIBRARIES}) endif() add_executable(main main.cpp) target_link_libraries(main C) where ${B_LIBRARIES} contains only B. The compiler will now complain /usr/bin/ld: cannot find -lA

Building 64bit application with makefiles using cmake-gui

问题 When I run cmake-gui and hit configure, I can specify the generator for my project. I can choose Visual Studio solution, Eclipse, makefiles etc... I am on 64bit system and want to build 64bit application. Till now, I used Visual Studio 10 Win64 generator to generate my solutions. No I want to (have to) build it with makefiles. But there is no options 32b/64b. Are makefiles for 64bit build used by default (on 64b system) and for 32b only after using something like export CFLAGS=-m32 inside my
