Description
Describe the bug
When I try to statically link jsoncpp into my project, I get the following error message:
[ 3%] Linking CXX executable ../../../../bin/jsontestrunner_exe
/usr/bin/ld: cannot find -ljsoncpp_static: No such file or directory
To Reproduce
Steps to reproduce the behavior:
- Add the following to
CMakeLists.txtfile:
set(BUILD_SHARED_LIBS False)
set(CMAKE_EXE_LINKER_FLAGS "-static-libstdc++ -static")
- Run
cd build && cmake .. && cmake --build .
Expected behavior
Have a statically linked library
Desktop (please complete the following information):
