Default compile directory

Default compile directory

[Sumit Narayan]

Hi,

Is there any way to set default compile directory?

The problem: I have a many sub-folders in my project and when I edit a
file deep inside subfolders and do M-x compile, I end up running make
in that subfolder, instead of the root folder. Is there any way for
Emacs to always run compile in the default folder?

One thing I figured was to change default compile command to be: cd
<project's root folder>; make. Is that the only/best way?

Thanks.
Sumit.

Hi Sumit,

You can use .dir-locals.el in your root folder and put something like:

(setq compile-command "cd <root folder>; make")

It will be evaluated every time you open a file in the folder. I think
it's a new feature of emacs 23.

Kind regards,

Thanks.

This is what I did:

Added
((nil . ((setq compile-command "cd <project root directory>; make"))))
in <project root directory>/.dir-locals.el.

When I open any file inside this folder, I am asked for permission to
apply the local variables

setq : (compile-command "cd <project root directory>; make")

For some reason, my response as 'y' or '!' does not make a difference.
When I give M-x compile, I still end up with "make -k".

Any idea why?

Thanks,
Sumit.

According to the info doc, the syntax is similar to a let-list.
So, delete the 'setq' and it should work.



-ap

Thanks Politz. I was also missing a dot.

For those who might be looking at this in future, this is how I got it
working. Add

((nil . ((compile-command . "cd <project root directory>; make"))))

in <project root directory>/.dir-locals.el.

Sumit.

Back to this topic.

This only works if I my frame has some code open. But if I am in an
eshell frame, it goes back to the default compile command - 'make -k'.
Is that how it is supposed to be?

Thanks,
Sumit.

No. You can also keep open a(n optionally minimised) second frame  
either with a buffer keeping open a file from your project's root  
directory, or a dired buffer from it, or the *compilation* buffer.  
When using GNU Emacs 23 you can in *compilation* buffer just type g  
(like update in dired) and the compilation process starts again.

If you're not confused, you're not paying attention.

Thanks Peter. This is a nice feature. I wasn't aware of it and I think
it is quite useful.

However, I have my compilation window close on its own if there were
no errors. To recompile, I will have to change to that buffer, which I
do not wish to. Emacs anyway saves the previous compile command. I
only need to give the compile command once in the project folder. But
if I move to another project, I will have to give the compile command
again. .dir-locals.el seems like something I could use.

Sumit.

In most cases you'll want to use M-x recompile to avoid this.
