the_rastaman · 04-11-2010, 09:36 PM

for a university project i need to run some .cpp files but when i tried this commands in terminal:

gcc -o potencia.cpp
g++ -o potencia.cpp
c++ -o potencia.cpp

gentoo compiles the .cpp files an what i need is in a certain way a executable file like a "a.out" or something like that, so anyone can help me? thanks for any information.

hi if you want a a.out file don't use '-o' option.
ex :- g++ potencia.cpp
-o is used to name the output file. if you want your output file to be named as output you can use the command below
g++ potencia.cpp -o output
OR
g++ -o output potencia.cpp

You don't run c++ source code. Using the same name for the binary as the source, you may have overwritten your input source.

You will want to read an intro article on C++ and using g++. The source may require libraries, or may have a make file. Look for a file named README or install to start.

i tried that one to, but the problem is that the command line does not generate an "output" or a.out. I can compile mi .cpp file but i cant run it.

Code:

g++ file1.cpp -o file1
./file1

Or

Code:

c++ file1.cpp
./a.out
