Check where include/library path variables like OpenCV_LIBS point to in unix

阅读更多关于 Check where include/library path variables like OpenCV_LIBS point to in unix

问题 When using some libraries like OpenCV with C/C++, variables like OpenCV_LIBS are used to point the compiler/linker to the relevant directories. Examples using cmake: include_directories( ${OpenCV_INCLUDE_DIRS} ) target_link_libraries( project_name ${OpenCV_LIBS} ) How can I check where such variables point at? I've tried typing set or printenv in terminal but it shows only some system variables. Also how can I set/change such variables? 回答1: Those variables are determined by cmake (see

Z3 Python bindings: init(Z3_LIBRARY_PATH) must be invoked before using Z3-python

阅读更多关于 Z3 Python bindings: init(Z3_LIBRARY_PATH) must be invoked before using Z3-python

问题 I installed the Z3 theorem prover on Linux, and am using its Python bindings (Z3Py). I tried to test a minimal example, but I immediately got the following error: z3.z3types.Z3Exception: init(Z3_LIBRARY_PATH) must be invoked before using Z3-python How do I fix this and get up and running with Z3? I'm not quite sure what that error message means. The Z3 documentation and tutorials don't seem to say anything about this or about init() , and the Z3-Python docs don't list any function called init

GNU ld cannot find library which is there

阅读更多关于 GNU ld cannot find library which is there

问题 The packages I'm toying with here are rather unknown, but nevertheless the problem is rather generic. Basically, I'm trying to compile Python module (called rql) with C++ extension. The extension uses external framework called gecode, which contains several libraries. I compiled gecode and installed locally. Now, let the output speak for itself: red@devel:~/build/rql-0.23.3$ echo $LD_LIBRARY_PATH /home/red/usr/lib red@devel:~/build/rql-0.23.3$ ls $LD_LIBRARY_PATH | grep libgecodeint
