The compilation

3.1.1.3 : The compilation

The compilation is decomposed in 4 steps :

Create a build directory in the main directory of our project
Go into it
Call cmake
Call make

So, let's create this build directory :

mkdir build

Then we go into it :

cd build

We call cmake :

cmake ..
-- The C compiler identification is GNU 7.2.0
-- The CXX compiler identification is GNU 7.2.0
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Detecting C compile features
-- Detecting C compile features - done
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Detecting CXX compile features
-- Detecting CXX compile features - done
-- Configuring done
-- Generating done
-- Build files have been written to: XXX/build

The .. is to call the parent directory as ../

Finally we call make :

make
Scanning dependencies of target hadamard_product_profiling
[ 50%] Building CXX object CMakeFiles/hadamard_product_profiling.dir/main.cpp.o
[100%] Linking CXX executable hadamard_product_profiling
[100%] Built target hadamard_product_profiling

Now, let's execute our program :

./hadamard_product_profiling
Hadamard product
tabResult[0] = 0
tabResult[0] = 0
tabResult[0] = 0
tabResult[0] = 0
tabResult[0] = 0

It seems, the execution is ok, but we will profile it with valgrind.
