sherrellbc opened this issue · comments
What are the steps to reproduce this issue?
- Create iPhone tool template
- Attempt to compile c++ code (replace main.m with main.cpp in Makefile)
#include <iostream>
int main() {
std::cout << "Hello World!";
return 0;
}
What happens?
Compilation fails
What were you expecting to happen?
Successful compilation
Any logs, error output, etc?

What versions of software are you using?
Operating System: Linux/Ubuntu 18.04
Toolchain Version: latest (non-swift) from instructions
SDK Version: 14.7 (generated by using the provided sdk create script)
Sorry, I updated the output to reflect use of the 14.7 SDK I generated using create_patched_sdk.sh.
It seems that the 14.4 SDK available from the repo will compile this code just fine. Interestingly, there is no $SDK/usr/include/c++ directory in the 14.4 SDK as provided by the repo. But there is one in the 14.7 SDK generated by the script (and in the SDK sources). The toolchain provides its own c++ directory at $TOOLCHAIN/include/c++
THEOS is the latest from master as of last week sometime. Same for the create SDK script I linked.
