Prevent vim :make from changing the current working directory? - perl

Question

Synopsis:
When calling vim's make command, it changes the current working directory (cwd) to the directory of the current file. It then runs the makeprg from there. I want to prevent the make command from changing the cwd, and instead call the makeprg from the directory of the parent vim instance
Example:
I have the following standard perl project hierarchy
project/
lib/
My/
Module/
Foo.pm
My PERL5LIB is set to
PERL5LIB=':lib'
In my .vimrc I have
compiler perl
set makeprg=perl\ -c\ %
I edit my module using vim from the root project level:
/path/to/project$ vim lib/My/Module/Foo.pm
In vim :pwd works as expected:
:pwd
"/path/to/project"
Also calling !perl -c works as expected, finds my project lib, and displays the result in a shell window:
:!perl-c %
OUTPUT:
perl -c lib/My/Module/Foo.pm
lib/My/Module/Foo.pm Syntax ok
However :make returns an error
:make
"Can't open perl script lib/My/Module/Foo.pm : No such file or directory"
Setting makeprg to pwd shows the problem
:set makeprg=pwd
:make
"/path/to/project/lib/My/Module"
So before make runs makeprg it is changing to the directory of the current file, which is why perl can't find 'lib/.../Foo.pm' there.
Is there any way to prevent make from doing this?

Answer 1

If Vim's :make command is changing the current working directory, and autochdir is not set, a plugin may have added an autocommand to the QuickFixCmdPre set. One plugin that does this is eclim, which calls the QuickFixLocalChangeDirectory() function if g:EclimMakeLCD is set to 1.
Use :au to find all the autocommands in your current configuration, paying particular attention to entries for QuickFixCmdPre and make.
