How to compile the cpp file?

[lihao2333]

Sorry, I'm a new man.
I think I should do something to compile the cpp file to executable file?
Should I need a Makefile?
Thanks

[hughperkins]

Need cmake See https://github.com/hughperkins/EasyCL#procedure-1

Yes, I did it as instructed. And then source ../dist/bin/easycl_activate.sh to set environment variables. However, if i want to try the testeasycl.cpp, should I run g++ testeasycl.cpp? How could I run this demo?
Thanks very much.

Do you have ../dist/bin/easycl_unittests ? https://github.com/hughperkins/EasyCL#how-to-run-self-tests

[hughperkins]

`ccmake ..` , change `BUILD_TESTS` to 'ON'

../dist/bin/easycl_unittests appears~
It works when i run LD_LIBRARY_PATH=../dist/lib ../dist/bin/gpuinfo and LD_LIBRARY_PATH=../dist/lib ../dist/bin/easycl_unittests.
Thank you very much~~
But if I want to test the test/testeasycl.cpp, what should I do ?
I do

g++ test/testeasycl.cpp -std=c++11 -Ithirdparty/gtest -Idist/include/easycl -I/home/geek/Proj/Intel/Install/hld/host/include/ -I.

in the root of this repo. But it not work, it report error like this:

Looking forward to your help

Testeasycl.cpp is compiled into easycl_unittests. It is the Testeasycl.main test
