    I'm trying to check to see if an application is installed in the rules section of a target.

In my case, I'm checking for doxygen.

But I'm currently having issues doing this using findstring.


When using findstring, it seems as though the whole string has to match before it will consider it a match.

The only problem is that the string I'm searching on is "command not found";. But depending on the shell you run it in, the stuff before command not found might look like:


bash: doxygen: command not found

or

sh: doxygen: command not found

Is there any easier way of accomplishing my end goal?

Thanks,
Randy

Searching for an error string is always a bad idea.  What if
the user
has their locale set to display errors in German?  You'd go
crazy trying
to search for all the different ways of saying "command
not found" in
every shell and every language.

It's not necessary either as the shell gives you a status
value when a
command fails to execute a command, which you can test e.g.

foo := $(shell doxygen --version >/dev/null 2>&1
&& echo "yes")

...will result in foo being "yes" if the command
was successful
otherwise blank.  If you want yes/no then you can do
something like:

foo := $(shell if cmd; then echo yes; else echo no; fi)

    Good points Brian. Thanks for the feedback. 

I will definitely go your suggested route.

Thanks again.
