I recently upgraded Linux to
GCC 6.4 version(/usr/local/gcc-6.4.0/lib/gcc/x86_64-pc-linux-gnu/6.4.0)
old version 4.6(/usr/lib/gcc/x86_64-redhat-linux/4.6.2)
However, the gcc path has not changed in R studio.
I tried to change using Sys.setenv(PKG_CXXFLAGS="-std=c++11"),
but it is not still working.
what should I do?
[linux]$ gcc --version
gcc (GCC) 6.4.0

I am trying to set up VScode to be able to the "Code Runner" package for C and C++ code with the Code Runner package, but it would always error with:
[Running] cd "d:\Desktop\Programming\For_fun\tester\" && g++ practice.cpp -o practice && "d:\Desktop\Programming\For_fun\tester\"practice
[Done] exited with code=1 in 0.123 seconds
I have discovered that compiling and running with wsl and ubuntu would work, but regular command prompt wouldn't. I presume that is a big indicator of what the problem is, but I have no idea how to resolve it or even start googling.
I am on Windows 10
This is my code:
#include <vector>
#include <iostream>
#include <string>
using namespace std;
int main() {
cout << "Hello World!\n";
return 0;
}
And these are the results of me trying to confirm whether I have the relevant packages installed:

Thanks!
It doesn't work. But I fixed the problem: Basically, I used the windows finder to find all instances of gcc.exe and deleted the folders within my program files that house them. Then I removed their paths from my environment variables. Finally, I did a clean reinstall of gcc-core and gcc-g++ through cygwin and it worked
I have a problem with arm-none-eabi-g++ compiler running on Windows.
When I run my makefile on Ubuntu, everything works fine.

arm-none-eabi-g++: error: CreateProcess: No such file or directory
I'm using MingGW on Windows. MinGW, make and G++ locations are added to Win PATH.
Compiler and make are the same versions on both OS.

More information
This is how one of my makefile targets look like
$(PROJECT).o: $(PROJECT).cpp
#echo start of $(#F)
$(CPP) $(CC_FLAGS) #./.symbols.txt -std=gnu++11 -fno-rtti #./.includes.txt -o $# $<
#echo end of $(#F)
Interesting thing is, that Windows build works fine only if the size of .symbols.txt and .includes.txt combined is lower than 32k. So it might look like it depends on ARG_MAX size (which is on MINGW 32k), but it's probably not true. Because another target in the same makefile looks like
$(PROJECT).elf: $(SYS_OBJECTS)
$(file > .sys_objects.txt, $(SYS_OBJECTS))
$(LD) $(LD_FLAGS) -T$(LINKER_SCRIPT) $(LIBRARY_PATHS) -o $# #./.sys_objects.txt $(LIBRARIES) $(LD_SYS_LIBS) $(LIBRARIES) $(LD_SYS_LIBS)
and it works well on Windows despite that sys_objects.txt size is about 90k.
Both $(LD) and variables $(CPP) variables are set to arm-none-eabi-g++.
Another thing I have noticed is that something on Windows adds a file like C:\Users\user\AppData\Local\Temp\ccQWU5K6.s to the end of g++ command (regardless if it fails or not). I have no clue where does this come from (maybe some MINGW support argument?).
Has anyone a clue why build fails on Windows with arguments bigger than 32k even if another target works fine with big arguments? Maybe it might be a coincidence.
I am trying to enable vtable verification in my project. When I try to use the flag (-fvtable-verify=std) I get an error g++: error: -fvtable-verify=std is not supported in this configuration.
Can you help me figure out what is going wrong?

I get an error that ‘literals’ is not a namespace-name when compiling the following
#include <complex>
using namespace std::literals;
...
its compiles fine on Windows with MSVC and even on OS X with clang, but fails on redhat 7 using either gcc and intel's icpc.

what am I missing?
ps: Even simple code like in this live demo doesn't work:(
libstdc++ that comes with GCC 4.8.x does not have those literals; they started shipping beginning with GCC 4.9.0.
I am using ubuntu 12.04
I have been trying to install gpuocelot for a few day now.
I recently installed llvm from the svn using
svn co http://llvm.org/svn/llvmproject/llvm/trunk llvm
./configure enableoptimized
sudo make
sudo make install
But to do this I had to update gcc to 4.7 which i had also done
Now when i run sudo ./build.py --install
I keep on getting the following error
ocelot/ocelot/ir/implementation/ExternalFunctionSet.cpp:28:34: fatal error: llvm/Assembly/Parser.h: No such file or directory
The following outputs might be of help

The LLVM C++ API, including the very existence and location of headers, is very unstable. This is why projects usually align themselves to some official release of LLVM, and I'm sure GPUOcelot follows the same pattern.
In top-of-tree LLVM, the header llvm/Assembler/Parse.h doesn't exist, which is why you can't find it. You should compile & link GPUOcelot vs. the LLVM version it supports officially. If GPUOcelot tries to follow the top-of-tree of LLVM, at least there should be a "known good revision" with which it works.
