header-files

What is the equivalent of numpy.get_include() as used here for Python, giving me the path to the directory where the Python header files are located? The header files are in include directory. You can find the include dir using the distutils.sysconfig module from distutils.sysconfig import get_python_inc get_python_inc() #this gives the include dir You can read about it here 来源： https://stackoverflow.com/questions/14375222/find-python-header-path-from-within-python

I have many different 3 axis sensors I am writing test code for. In the C files for each of them, I have the same char string defined: char axis[3][8] = {"X", "Y", "Z"} which I use when I "for" loop results to print the axis that is failing like this: DEVICETEST_LOG("%s Failed %s axis for Min range\n",device_name[DUT], axis[i]); I was thinking to save some space I could define a character string array in a header file to use all over the place. I have tried a number of things, but I can't seem to get an array of strings defined in my header file that I can iterate through to pass a compile. In

Should every .C or .cpp file should have a header (.h) file for it? Suppose there are following C files : Main.C Func1.C Func2.C Func3.C where main() is in Main.C file. Should there be four header files Main.h Func1.h Func2.h Func3.h Or there should be only one header file for all .C files? What is a better approach? It's unusual to have a main.h since there's usually nothing that needs to be exposed to the other compilation units at compile time. main() itself needs to be exposed for the linker/start-up-code but they don't use header files. You can have either one header file per C file or,

I am using Kdevelop in Kubuntu. I have declared a structure in my datasetup.h file: #ifndef A_H #define A_H struct georeg_val { int p; double h; double hfov; double vfov; }; #endif Now when I use it in my main.c file int main() { georeg_val gval; read_data(gval); //this is in a .cpp file } I get the following error: georeg_chain.c:7:3: error: unknown type name 'georeg_val' (This is in the georeg_val gval; line) I would appreciate if anyone could help me resolve this error. In C one has two possibilities to declare structure: struct STRUCT_NAME {} ; or typedef struct {} STRUCT_ALIAS; If you use
