hello,

i have this make file in order to generate hello.exe.

hello.c compiled with visuel c++.

Code:

#include <iostream>
using namespace std;
void main(void)
{
 //printf("Hello world !!\n");
  cout<<"hello world c++";
}

but i get this error:

creating binary "../bin/hello .exe"
ppc_4xx-g++: .exe: No such file or directory
make: *** [bin] Erreur 1

please some one can help me to solve this problem.

thank you

Hi,

what did you actually type to start the compilation process?
I looks like you mistyped somewhere 'hello.exe' and put in a space between 'hello' and '.exe':

Code:

creating binary "../bin/hello   .exe"
                              ^ there should be no space here

I exaggerated the space.

The problem is in how you're defining your variables, because it's picking up a space somewhere. This often happens when you leave a trailing space at the end of a line.

The giveaway is that the result of this command:

Code:

    @echo 'creating binary "$(BIN)"'

Is this... note the space in the filename:

Code:

creating binary "../bin/hello .exe"

Breaking it down, $BIN is defined like so:

Code:

BIN=    $(BINDIR)/$(NAME)$(SUFFIX).exe
BINDIR= ../bin
NAME=   hello 
SUFFIX=

If you go to the end of line in vi, you'll find a trailing space after hello on the NAME= line. You'll see it here in your web browser when you highlight the code with your mouse. Delete it, and that should solve your problem.

i remove the space after hello( NAME= hello)

now it appears this problem: creating binary "../bin/hello.exe"
/home/opt//eldk_4.2/usr/../ppc_4xx/usr/lib/crt1.o

.rodata+0x4): undefined reference to `main'
collect2: ld returned 1 exit status

It helps to put these things in code tags, so that among other things, we don't end up with the smiley.

Something clearly went wrong in the construction of the variables for this command:

Code:

   @$(CC) -o $(BIN) $(OBJ) $(LIBS)

Because that's the step at which the script is failing, or else we'd have seen "... done" echoed in the output. The path looks like it has been smashed together with some things which are invalid, and I can't begin to help you correct it because I don't know what this command syntax is supposed to look like.

The best way to find syntax problems like this when you're developing a new script is to echo the command string. Then compare that to what you were expecting.
