Re: sourcing scripts inside Make

[Ted Stern]

Dear Aditya:

1) Generally it is recommended to use a Bourne-syntax shell for
executing commands inside MAKE.  It has a smaller startup overhead.
If you require csh, you will have to specify it:
   
   SHELL = /bin/csh

2) Each line of the target commands is executed with a new sub-shell.
If you want your setups to work for several commands, you have to
string them together, like so:


   foo:
   <TAB> command 1 ; \
   <TAB> command 2 ; \
   <TAB> command 3

3) If you have set your shell to csh, there is a good chance that the
.cshrc file is being sourced anyway.
