QUESTION :
I have emacs version 24.3.1 (i386-mingw-nt6.2.9200) installed on a Windows 8.1 machine. I am trying to use the ledger.el distributed with John Weigley’s ledger (version 2.6.1). While the lisp file loads into emacs and seems to function (I have the .el file in the right place and my .emacs file refers to it), when I try to use the C-c C-a to add a new transaction based on an old transaction, I get the following error:
Searching for program: permission denied, ledger.
Any help at all would be greatly appreciated.
ANSWER :
The error message tells you that you do not have a program named ledger installed in your exec-path.
If you do have a program named ledger installed somewhere then add its path (location) to the value of exec-path.
See the Elisp manual, node Subprocess Creation for information about exec-path.
See also environment variables PATH and EMACSPATH in the Emacs manual, node General Variables.
