Hey
I have been trying to compile my programs using
Visual Studio Express 2005 from the Command Line
in windows xp.
One tutorial says:
cl -GX prog1.cpp
but the compiler says something like "-GX will not be used
in a future release of the compiler....", and it will NOT compile.
Of course I can use the GUI to compile, and then it all works fine,
but I think I should be able to do it by hand, so to speak....in a
DOS prompt. ;-)
Any suggestions

/GS would be want you want. Not -GS. However, this switch instructs the compiler to do buffer security checks for you. Which is unecessary since it is ON by default. /GS- would disable it.
cl /EHs prog1.cpp is probably the most minimalist choice. It compiles prog1.cpp with exception handling.

Didn't correctly read your original post. You were trying to use GX, not GS. GX enables exception handling. However it is deprecated. Use /EH options instead, like the exaple on my previous post.

hmm...
The compiler still complains: no include path set
If I run vcvars32.bat, then it works, but I would like the change
to be PERMANENT

Put the contents of vcvars32.bat in \autoexec.bat.

hi dwks
Nope, unless I ALWAYS run autoexec.bat, before I compile....
seems very complicated.....hmmmm...

Ah, yes. The environment variables.
Open vsvars32.bat with a text editor. It's located on your visual studio folder/common7/tools. You see those set commands? Those are the environment variables you need to add to your system environment variables.
Right-click my computer->Properties->Advanced->Environment Variables. Add each and one of those to the system variables part.

AUTOEXEC.BAT is always executed when the computer turns on. You'll just have to reboot, or at least re-launch your DOS prompts.Nope, unless I ALWAYS run autoexec.bat, before I compile....

It might be run when you run a particular kind of backward compatibility DOS emulator, I didn't think it was touched at all in a normal XP boot up.
Besides, the environment can be set on a per user basis in XP, so a global autoexec.bat doesn't make sense.
Create a cmd file with
Code:call vcvars32.bat start cmd

If at first you don't succeed, try writing your phone number on the exam paper.
