    Starting with Dev C ; a problem

    When trying to compile an example program I get this error :

    ================================================== ===================
    Compiler: Default compiler
    Building Makefile: "D:\Dev-Cpp\Examples\Hello\Makefile.win"
    Executing make...
    make.exe -f "D:\Dev-Cpp\Examples\Hello\Makefile.win" all
    g++.exe -c Hello.cpp -o Hello.o -I"D:/Dev-Cpp/lib/gcc/mingw32/3.4.2/include" -I"D:/Dev-Cpp/include/c++/3.4.2/backward" -I"D:/Dev-Cpp/include/c++/3.4.2/mingw32" -I"D:/Dev-Cpp/include/c++/3.4.2" -I"D:/Dev-Cpp/include"

    g++.exe: Hello.cpp: No such file or directory
    g++.exe: no input files

    make.exe: *** [Hello.o] Error 1

    Execution terminated
    ================================================== ====================

    what could be the problem?

    I'm using ver 4.9.9.2

    g++.exe: Hello.cpp: No such file or directory
    It can't "find" your Hello.cpp file. Either, you didn't save it, you saved it in the "wrong place", or you need to set-up your paths differently. As an experiment, you might try putting Hello.cpp in the root directory on your C-drive.

    I don't use Dev-C++, so I can't tell you exactly how to fix this problem. It's a popular compiler/IDE, so someone should be able to help you with it.

    Hang in there! Every time I've tried a new compiler, there have been snags.. I'm happy if I can get Hello World working on the first day.

    Iv never seen that error but it could be that somthing was not installed. You could uninstall it and re-install it again.

    I'm also using Dev-C++ but I've never used make.exe before so I'm not too sure how much this is going to help.

    I'm relatively familiar with the file functions (fopen(), etc) and I know that with those functions the file has to be in the same folder as the program that you are running, so try moving Hello.cpp to the same folder that you are running your program from.

    I've somehow also managed to break my dev CPP even though it was working a few secs ago. I however get the error that several re-install won't fix.
    There doesn't seem to be GNU Make file in PATH or in Dev C++'s bin path. Please make sure that you have GNU make and adjust Bin setting or system PATH environment variable and that make setting in Compiler Option contains correct filename, otherwise you'll not be able to compile anything.
    I've added the path to the Make exe to my system path variable

    I have used Dev-C++ ---- why use a makefile? Sort of begs the question as to why you're using an IDE to compile and build your program. Or are you just using Dev tp edit the program and the GNU compiler to make it?

    Make sure you are actually IN the "D:\Dev-Cpp\Examples\Hello\" directory before you run the make. The error message is very clear: Hello.cpp cannot be found. I see no evidence that make attempted to change directories, so unless you were already in the right place, it's not going to find the source file.

    Newer versions of Dev-C++ use make whenever you create a project, AFAIK. The OP probably just tried to compile a simple hello, world program and came across this error.

    As a suggestion, try putting your source file in D:\ (which you may already have tried) or in D:
    Dev-Cpp\Bin. Or try re-creating the project file. Or edit the project file yourself: where ever it says Hello.*, insert the full path to the source file before the filename.

    Or maybe you could just use code::blocks
    Ive never had probelms with it.

    Iv done that twice

    I'm relatively familiar with the file functions (fopen(), etc) and I know that with those functions the file has to be in the same folder as the program that you are running, so try moving Hello.cpp to the same folder that you are running your program from
    Tried, negative result

    I've added the path to the Make exe to my system path variable
    How do I do that?

    Or are you just using Dev tp edit the program and the GNU compiler to make it?
    I'm using the Dev C IDE

    Make sure you are actually IN the "D:\Dev-Cpp\Examples\Hello\" directory before you run the make. The error message is very clear: Hello.cpp cannot be found. I see no evidence that make attempted to change directories, so unless you were already in the right place, it's not going to find the source file.
    I copied the files to that bin directory, same result

    code::blocks
    I'm sorry I don't understand

    Code::Blocks is an alternative to Dev-C++. It has more features and is generally a better program. You could try it out if you wanted to. codeblocks.org

    Anyway . . . as another experiment, try opening a command prompt (Start->Accessories->Command Prompt, usually), CD'ing to the location of your .cpp file, and compiling the file by hand. Something like this might happen:
    Code:
    C:\Windows>cd "\Documents and Settings\User\cpp"
    
    C:\Documents and Settings\User\cpp>g++ hello.cpp -o hello.exe
    Command not found
    
    C:\Documents and Settings\User\cpp>D:\Dev-Cpp\Bin\g++ hello.cpp -o hello.exe
    ... some weird g++ error ...
    
    C:\Documents and Settings\User\cpp>set PATH=D:\Dev-Cpp\Bin;&#37;PATH%
    
    C:\Documents and Settings\User\cpp>g++ hello.cpp -o hello.exe
    
    C:\Documents and Settings\User\cpp>hello
    Hello, World!
    
    C:\Documents and Settings\User\cpp>exit
    Try something like that and see what happens. What error messages do you get?

    I might be wrong but DevCpp (and MingW) may not work well if
    1) it is installed to a directory whose name contains spaces (e.g Program Files),
    2) the source path contains spaces
    3) the source is located in the same directory as DevCpp.

    I think the last one may apply here.
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.

    That's true, it might not -- but in this case, Dev-C++ is installed in the default location: \Dev-Cpp.
    2) the source path contains spaces
    Again, possibly true -- but when the source file is located in the root of the drive, this shouldn't be a problem.
    3) the source is located in the same directory as DevCpp.

    I think the last one may apply here.
    On the contrary -- it might work better. At least that was my thought.

    Anyway, it's irrelevant -- the OP has tried in the same directory and elsewhere, apparently.

    @OP: Did you modify your path at all? Did Dev-C++ do it automatically? Are you using Windows Vista?

    You can check your path by typing "path" at a command prompt.

    Re:

    I got this when manual compiling :

    Code:
    D:\Dev-Cpp\Examples\Hello>g++ hello.cpp -o hello.exe
    'g++' is not recognized as an internal or external command,
    operable program or batch file.
    
    D:\Dev-Cpp\Examples\Hello>D:\Dev-Cpp\Bin\g++ hello.cpp -o hello.exe
    
    D:\Dev-Cpp\Examples\Hello>hello
    Hello ! This is a console app.
    To create a console, go to Project Options and select
    'Win32 Console'.
    Press q to quit
    q
    
    D:\Dev-Cpp\Examples\Hello>set PATH=D:\Dev-Cpp\Bin;&#37;PATH%
    
    D:\Dev-Cpp\Examples\Hello>g++ hello.cpp -o hello.exe
    
    D:\Dev-Cpp\Examples\Hello>hello
    Hello ! This is a console app.
    To create a console, go to Project Options and select
    'Win32 Console'.
    Press q to quit
    q
    
    D:\Dev-Cpp\Examples\Hello>
    So, it works manually

    No, I have this
