Hi Guys,
I have a little problem with the g++ and wanted at first to ask if such
question belong to this ML too or not.
(I haven't found a g++-ML so I think so, but I'm not sure)
When this will be answered I ask my reall question
Greetings,
Gregor

Hi Gregor,
This is the right place to ask about g++ too. GCC is
more than just the C compiler;)
Yours sincerely,
Bjorn

Hi Guys,
ok, here comes my real problem:
I'm just trying to walk trough the QT-Tutorial and there I have to compile
more than one file into a binary.
The commands I have to use is:
$ g++ -L/foo/ -I/bar/ -c file1.cpp
$ g++ -L/foo/ -I/bar/ -c file2.cpp
and at last:
$ g++ -o endfile file1.o file2.o
Or have I forgott something?
Because the first to commands he do properly but when I want to compile the
real binary he tells that nearly the whole X.o is wrong.
Should I add a token or what could it be?
Greetings
Gregor
PS:
Yes, you're right, I have just started to program
PPS:
I will send the error the g++ give out soon to this list.

Hi Gregor,
The -L option is for specifying extra directories with
libraries during linking. You probably also want to
specify a number of libraries to link agains using the
-l option. Have a look at the man pages on gcc.
Yours sincerely,
Bjorn

Hi Guys
How can I say to g++ that he should print out the errors in a
file not in the stdout (=screen)?
And:
If I want to compile a X.o from a X.cpp shall I use gcc or g++?
Both do it, but what shall i Rather use?
Or shouldn't I mind about it?
Greetings
Gregor

It outputs errors to stderr not stdout. stderr has file descriptor 2;
you could use shell redirects, e.g.:
g++ -c foo.cc -o foo.o 2>errorfile

The main differences between g++ and gcc are that g++ will compile .c
files as if they were C++ and that g++ automatically includes libstdc++
when it is asked to link. You should use g++ for your link step.
