Question

I have a problem running a simple Hello-world program in C++ on my Windows XP. I have written a post here:

Using the g++ C++ compiler from cygwin

where I stated the problem and I received many helpful replies, which solved some things. However, I still cannot run my hello-world program. Please, have a look at the post, I have included the program there. A friend of mine is able to run this program on his machine without problems. So, the problem should be in my system or libraries or something else, but I cannot figure what. In the ‘Edited’ section of my post, I have included what error messages exactly I get.

Here is what I receive when I try to compile the program like this:

g++ hello.cpp

From the cygwin shell:

When I try g++ hello.cpp, I get:

hello.cpp:1: parse error before character 0357 hello.cpp: In function 'int main()': hello.cpp:'cout' undeclared (first use this function) hello.cpp: (Each undeclared identifier is reported only once hello.cpp: for each function it appears in.) hello.cpp: 'endl' undeclared (first use this function) g++.exe: hello.cpp: No such file or directory g++.exe: No input files g++.exe: hello.cpp: No such file or directory g++.exe: No input files g++.exe: hello.cpp: No such file or directory g++.exe: No input files g++.exe: hello.cpp: No such file or directory g++.exe: No input files g++.exe: hello.cpp: No such file or directory g++.exe: No input files 

And here is what I get when I try to compile the program (again with g++ hello.cpp) from the DOS command prompt:

When I try g++ hello.cpp, I get:

hello.cpp:1: parse error before character 0357 hello.cpp: In function 'int main()': hello.cpp:'cout' undeclared (first use this function) hello.cpp: (Each undeclared identifier is reported only once hello.cpp: for each function it appears in.) hello.cpp: 'endl' undeclared (first use this function)

It looks like you have somehow got an illegal character in your code. Did you type the code in yourself or copy & paste it? If the latter, the source you copied from may be suspect in some way – type the code into the editor yourself, save it and recompile.
