Trouble setting up c++ with VSCode. Include error, missing binary operator and xlocale.h not found

62 views Asked by At

I'm trying to test the following C++ code on VSCode, but can't seem to get it to work. So far online searches haven't provided results. Tried to change the compilers but it doesn't seem to fix itself. Not sure how I proceed further. OS is ubuntu if relevant:

#include <iostream> //input output library, containing printing and asking input etc.

int main() {
    std::cout << "test"; //statement
    return 0; //tells system it terminated correctly
}

The following errors are mentioned under the problems window:

test.cpp

#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit (/mnt/F894C3B494C373A2/Downloads/c++/test.cpp).

cannot open source file "xlocale.h" (dependency of "iostream")

studio.h /usr/include

missing binary operator before token "(" .. a few times

libc-header-start.h /usr/include/x86_64-linux-gnu/bits

missing binary operator before token "("

cdefs.h /usr/include/x86_64-linux-gnu/sys

missing binary operator before token "("

The terminal window has this output:

The problem, after some hours, lay in the fixed header lines of the mesa sdk apparently. Using

GCC_VERSION=`gcc --version | grep ^gcc | sed 's/^.* //g'`
$MESASDK_ROOT/libexec/gcc/x86_64-pc-linux-gnu/$GCC_VERSION/install-tools/mkheaders $MESASDK_ROOT

solved it.
