I solved this by looking for an env variable that will only be set on windows. ifdef OS RM = del /Q FixPath = $(subst /,\,$1) else ifeq ($(shell uname), Linux) RM = rm -f FixPath = $1 endif endif clean: $(RM) $(call FixPath,objs/*) Because %OS% is the type of windows, it should be set … Read more
There are many good answers here already, but I wanted to share a more complete example that both: doesn’t assume uname exists on Windows also detects the processor The CCFLAGS defined here aren’t necessarily recommended or ideal; they’re just what the project to which I was adding OS/CPU auto-detection happened to be using. ifeq ($(OS),Windows_NT) … Read more
I think the following should work. I’m not sure about win32 though. if [[ “$OSTYPE” == “linux-gnu”* ]]; then # … elif [[ “$OSTYPE” == “darwin”* ]]; then # Mac OSX elif [[ “$OSTYPE” == “cygwin” ]]; then # POSIX compatibility layer and Linux environment emulation for Windows elif [[ “$OSTYPE” == “msys” ]]; then … Read more
There are predefined macros that are used by most compilers, you can find the list here. GCC compiler predefined macros can be found here. Here is an example for gcc: #if defined(WIN32) || defined(_WIN32) || defined(__WIN32__) || defined(__NT__) //define something for Windows (32-bit and 64-bit, this part is common) #ifdef _WIN64 //define something for Windows … Read more
