bits/stdc++ is a GNU GCC extension, whereas OS X uses the clang compiler. However, you can still make it work by manually creating the header file.
- Inside the directory /usr/local/include/
- Create a directory named bits (mkdir bits)
- Create stdc++.h file (touch stdc++.h or vim stdc++.h)
- Paste the contents of the stdc+.h file here
or
- Inside the directory /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/
- Create a directory named bits (mkdir bits)
- Create stdc++.h file (touch stdc++.h or vim stdc++.h)
- Paste the contents of the stdc+.h file here
Now it should compile as expected
I have also included "using namespace std;" in this file. So, from now on you dont need to write it everytime you create a cpp file.
