Oh, and by the way, another way you can do this, using only makefile syntax so
it doesn't involve the shell at all, is to use the $(wildcard ...) function with
a full filename to see if it exists, and then use that in a $(if ...) test.
Like so:
DRIVE=$(if $(wildcard c:/tools), c:/tools, c:/altTools)
This technique has the advantage of working whether you're using make in --win32
or --unix mode:
[EMAIL PROTECTED] /tmp/bgcc> ls -la C:/tools
ls: C:/tools: No such file or directory
[EMAIL PROTECTED] /tmp/bgcc> cat makefoo
DRIVE=$(if $(wildcard c:/tools), c:/tools, c:/altTools)
all:
echo drive is ${DRIVE}
[EMAIL PROTECTED] /tmp/bgcc> make -f makefoo
echo drive is c:/altTools
drive is c:/altTools
[EMAIL PROTECTED] /tmp/bgcc> make --win32 -f makefoo
echo drive is c:/altTools
drive is c:/altTools
[EMAIL PROTECTED] /tmp/bgcc> mkdir C:/tools
[EMAIL PROTECTED] /tmp/bgcc> make -f makefoo
echo drive is c:/tools
drive is c:/tools
[EMAIL PROTECTED] /tmp/bgcc> make --win32 -f makefoo
echo drive is c:/tools
drive is c:/tools
[EMAIL PROTECTED] /tmp/bgcc>
since it depends only on the cygwin dll's path-handling abilities, and not on
the nature of the shell that is being used to execute the commands.
cheers,
