Re: Compile mode in emacs!!

[Nazir]

Hi Peter,

 

Oops!! ... when I said "printenv", in the Mx-compile, it shows a different value for "PATH", from the one I see in the terminal.

I guess, you are right. Could you please tell me how to fix this?

Infact, when I said "printenv", I saw a big list, where in PATH_USER had the correct value, where as the PATH variable was referring to an incorrect value.

I also changed the path in Mx-compile, using "setenv PATH <value>", but it gets reset to a different value!!

 

Thanks,

Nazir

So the question is, why has GNU Emacs another another PATH value
active? Do launch it from some menu? I looks as if your login shell
provides a different environment than what you use in an interactive
shell. If you fix this issue, then GNU Emacs will find the same
compiler as you in some shell.

As I showed in my examples: you can use env to set particular
environment variables.

Then my guess is that some environment variables reset the value. You
can, for example do M-x compile RET and then erase the default make
command and substitute it with env or printenv to see which
environment the compile process sees. Then some corrections can be made.

I don't see this. There is a customisation group for the compilation
process (C-h f compile RET and you'll find a hint in the *Help*
buffer or via menus Options -> Customize Emacs -> Specific Group…,
name completion works), but there is nothing to set the compiler
explicitly. This is done in the shell or in Makefiles, as determined
by a configure script for example, or set by the programmer.
