Programming tools Chapter 10 In this chapter we introduce programming tools that can be used to solve the exercises. 10.1 GCC GCC stands for the Gnu Compiler Collection. It is a collection of compilers (C, C++, FOR- TRAN, Fortran 90, java) free of charge [?]. The C++ compilers are very good and produce reasonably efficient code. In this section, we explain how to compile a C++ program. The following command: g++ -o hello hello.cpp compiles the C++ source file hello.cpp into the executable hello. The compiler command is gcc or g++ with the following options. • -Idirectory: Include files directory • -O: Optimization • -g: Debugging • -p: Profiling • -o filename: output file name • -c: Compile, no link • -Ldirectory: Library directory • -lfile: Link with library libfile.a Here is another example: g++ -o foo foo.cpp -I/opt/include -L/opt/lib -lblas compiles and links the file foo.cpp using include files from /opt/include/ (option -I) and linked with a library that is situated in the directory /opt/lib: For optimizing code, we have to use the compilation options : -O3 -DNDEBUG 235
