The default compiler for c programs is gcc and g++ for C++ programs.

If necessary, it is possible to load the module gcc if you need a different version of the compiler.

module load gcc

In order to compile a program using a cplex library, you need to load the modulecplex-studio

module load cplex-studio 

If you program have a unique file, you can use the following command to create an optimized program

gcc -O -Wall -o hello hello.c

If you need to debug your program replace « -O » option bug « -g » option.

If the program has more than one file it is custom to create objets files then assemble the program. It is the way used to create a Makefile.

gcc -O -Wall -c hello1.c
gcc -O -Wall -c hello2.c
gcc -O -o hello hello1.o hello2.o

For C++ program need to change the command gcc with g++

g++ -O -Wall -c hello1.c
g++ -O -Wall -c hello2.c
g++ -O -o hello hello1.o hello2.o

Compiling a C program using Cplex.

gcc -O -Wall -DNDEBUG -DIL_STD -c lpex1.c
gcc -O -o lpex1 lpex1.o -lcplex -lm -lpthread

Compiling a C++ using Cplex and Concert.

g++ -O -Wall -DNDEBUG -DIL_STD -c cutstock.cpp
g++ -O -o cutstock cutstock.o -lilocplex -lconcert -lcplex -lm -lpthread
