TaskingScheduler.hpp: No such file or directory

[varunmittal91]

While trying to include <Grappa.hpp>, compiler returns TaskingScheduler.hpp: No such file or directory

I cannot find this file and a lot of include file seems to be dependent on this.

Could you give some more details on what you're doing?

Without any context, I'm guessing you're trying to link against an installed version of Grappa, as described in the two sections here, "Installing Grappa" and "External builds / Using Grappa as a library":
https://github.com/uwsampa/grappa/blob/master/BUILD.md#installing-grappa

Is that right? If so, and you didn't use --prefix when running configure, make sure you're adding all the include paths listed in the file <grappa repo>/build/Make+Release/install/share/Grappa/grappa.mk.

But maybe that's not what you're doing. Let me know!

I am trying to write hello_world program.

To compile this is what I am doing: g++ test.cpp -I Make+Release/install/include/Grappa/ -I Make+Release/install/include/ --std=c++11 -L Make+Release/install/lib/ -lGrappa

[nelsonje]

Great. You need more compiler flags than that. Look at what is in install/share/Grappa/grappa.mk for the full set.

[nelsonje]

In fact, I suggest following the directions at the top of that file to create a makefile that will deal with the flags automatically.

[varunmittal91]

Found this, -I$(GRAPPA_PREFIX)/include/Grappa/tasks
What if we change the include path inside headers to accommodate tasks.

Also makefile is generating .exe targets on Linux, which fail.

[nelsonje]

Not sure I understand. Look in applications/demos/standalone for an example of using the grappa.mk GNU Make include file; if you can do "make install" successfully on Grappa, you should be able to "source /bin/settings.sh" and then say "make" in applications/demos/standalone and get a working binary.

As a side effect, you'll see all the flags that the configure script decided were necessary to build a Grappa application. You need a bunch of flags set; more than just C++11 and include paths; for instance, you need to link with your MPI library.

Can you tell me the exact command you're running? If there's a bug in our
build or documentation I'd like to fix it. (Make sure that you're sourcing
settings.sh from /build/Make+Release/install/bin and not the
build directory itself.)

And we do have a Docker image for single-node operation:

Thanks for helping me setup the repository, I am having trouble reading
environment source file.
Tried building several times.
It says bash: /grappa/build/bin/env.sh: No such file or directory
Is there a per-built docker/vm image with environment setup.
