Lỗi can not open source file iostream.h năm 2024

Hi Tim,

I really want to clear up the confusion, but I didn't have what you have in mind. Not sure if I have it now too, to be accurate. First of all,, there is no such thing as mpiCC in my MPICH2 installation. See first code block of post

6, which lists what it has. So you mean how am I compiling a C++ with MPI program? If this is the case [if not, *please* let me know and I will report back ASAP], then I would do this [for compiling this .cpp example]:

gsamaras@pythagoras:/mpich-3.1.4/code$ ../../mpich-install/bin/mpic++ ring.cpp -o r gsamaras@pythagoras:/mpich-3.1.4/code$ mpiexec -n 2 ./r

This won't compile with g++, because of MPI errors.

Notice that I also tried to compile what I have in post

6 with g++, but it didn't recognize -mkl again.

Thanks,

George

EDIT:

It compiled with:

../mpich-install/bin/mpic++ -o test n.cpp -I../intel/mkl/include ../intel/mkl/lib/intel64/libmkl_scalapack_ilp64.a -Wl,--start-group ../intel/mkl/lib/intel64/libmkl_intel_ilp64.a ../intel/mkl/lib/intel64/libmkl_core.a ../intel/mkl/lib/intel64/libmkl_sequential.a -Wl,--end-group ../intel/mkl/lib/intel64/libmkl_blacs_intelmpi_ilp64.a -lpthread -lm -ldl

from a new directory I created. Not sure why this worked, but it compiled by just giving a warning:

warning: deprecated conversion from string constant to âchar*â [-Wwrite-strings]

 Cblacs_gridinit[&ictxt, "Row", nprow, npcol];
                                            ^
EDIT_2:

Just for the future users:

However, it will produce a floating point exception [which is weird, since I took it from a guy that knows what he is doing]:

Hello, so I am new to coding and wanted to use VS Code to code in C++, so I installed it, installed C/C++ IntelliSense v0.12.4 and followed instructions on the VS Code website to make a c_cpp_properties.json file and copied the code into it like they said. When I open my .cpp project that I had made in notepad++, I get the error: "

include errors detected. Please update your includePath. IntelliSense features for this translation unit [directory\file.cpp] will be provided by the Tag Parser. [9, 1]

cannot open source file "iostream" [9, 1]"

My .cpp code `

include

using namespace std;

int main[] { string firstName, lastName; double hourRate, numHours;

    cout > lastName;
    cout > hourRate;
    cout > numHours;
    cout
