compilation

问题 I would like to generate a Static Library file in Windows using MSVC / IXX which is macOS and Linux compatible. I'm using C (Let's say C99 ) and the functions are really simple. For example: void AddArray(float* mA, float* mB, float* mC, int numElements){ int ii; for(ii = 0; ii < numElements; ii++){ mC[ii] = mA[ii] + mB[ii]; } } Is there a way to build the Library only once on Windows and use it everywhere? If not on windows, could it be done on Linux and work on Windows and macOS? The idea

问题 I asked this question a while back: How to make C library installable with angle brackets as <mylib.h> on Mac. I am trying to do the same sort of thing, but don't exactly remember all the details / I'm not sure if I'm doing it right. So I have a production example working, but it seems like things aren't organized right (even though it seems to be compiling and running properly). My question is, how can I clean this up and remove some duplication and remove anything unnecessary? So here is my

问题 I'm on Windows trying to learn some OpenGL. I Installed mingw and have a test file. I put my test.c file in a glut folder, which contains glut files such as the glut32.dll and library file. I used mingw in cmd to run the file using this: gcc opengl.c -o opengl -lGL -lGLU -lglut And I got this error: opengl.c:1:23 fatal error: GLUT/glut.h: No such file or directory #include <GLUT/glut.h> compilation terminated. Not sure what I'm doing wrong, anybody know? Thanks! 回答1: First of all you need to

问题 I tried putting all xib files together in a folder in my project. And then I add this folder into the Xcode project, Hoping that Xcode may recognized them and put them in the directory I want in target package. But when I ran the target, the console(NSLog) told me that the nib file could not be found. I looked into the directory, there are xib files there instead of nib file. Here comes the question mentioned in the title. Can I achieve that? Here is the scene: I built the project. Then Xcode

问题 In (GNU) make, I want a variable to be assigned a value when the build chain of specific targets are starting. For targets a.so and b.so , each depending on b.o , I can do this manually like this: # Rules all: a.so b.so a.so: b.o @echo Current .so is $(current) touch $@ b.so: b.o @echo Current .so is $(current) touch $@ b.o: @echo Current .so is $(current) touch $@ # Set the "current" variable based on which .so is being build a.so: current = a.so b.so: current = b.so Here, current has the
