[Dev-C++] Compiling with g++ in a comand-line

[<Ala...@mx...>]

 Hi,  I'm testing Dev-Cpp and GCC compliler, and I'd like to use GCC (g++)
for command-line compiling in WinNT,  but I've got troubles and I don't know
why... I've checked the MingGW site and the compiler optiosn that I'm using
are correct....   I haven't been able to compile any suurcefile using g++
(Packed in dev-cpp) in command-line...  Does somebody have a idea or a site
where I can get information?

  THANKS.  Alan

Did you add the switches -I"C:\MinGW\include" 
-I"C:\MinGW\include\c++\3.2" -L"C:\MinGW\lib" ( -mconsole (or -mwindows) 
and -lmsvcrt (adapted to your directories) ? Because I noticed that when 
all that is not there it doesn't find any header or library.

If you wan't to use MinGW from the command line, then you should 
download the latest MinGW package, and install it. That way gcc will 
find everything, and no need to add -L and -I stuff (except for your own 
libs and includes). It is also a good idea to put the .../gcc/bin 
directory to your PATH, that way you can use gcc from anywhere.

The usage is as follows (roughly):
gcc -Wall -c -o source1.o source1.cpp
gcc -Wall -c -o source2.o source2.cpp
...
gcc -o program.exe source1.o source2.o ...

You may replace gcc with g++ for c++ code. You can ask me about usage 
from command line, as I have used it a lot, and I still use it a lot 
nowadays.

Alan, if you could post the errors you get, that would help the most.
