Question

error:

cxx.cpp:5:13: error: missing binary operator before token "("
cxx.cpp:7:15: error: missing binary operator before token "("

code:

  #if definied(_WIN32) || definied(_WIN64) || definied(__WIN32__)
        const char * PORT = "COM1";
    #elif definied(__linux) || definied(__linux__) || definied(linux)
        const char * PORT = "dev/ttyS1";
    #else 
        const char * PORT = NULL;
    #endif

Questions:

1. the compiler is waiting an new defined() call?
2. it can detected any linux(and variants) or windows version?

thanks in advance.

Answer 1

You misspelled defined:

#if definied(_WIN32) || definied(_WIN64) || definied(__WIN32__)

#elif definied(__linux) || definied(__linux__) || definied(linux)

should be:

#if defined(_WIN32) || defined(_WIN64) || defined(__WIN32__)

#elif defined(__linux) || defined(__linux__) || defined(linux)
