3.4.5.1 : Compilation



Sur mon ordinateur le programme nvc++ est installé à /opt/nvidia/hpc_sdk/Linux_x86_64/20.11/compilers/bin/nvc++.

Appellons CMake avec le bon compilateur :

cmake .. -DCMAKE_CXX_COMPILER=/opt/nvidia/hpc_sdk/Linux_x86_64/20.11/compilers/bin/nvc++
-- The C compiler identification is GNU 9.3.0

Bien entendu, cela n'est valable que pour un programme C++, car le compilateur C n'a pas changé.


Appellons make :
