RE: What's the meaning of X_ARCH :sh= /usr/bin/arch

[Xu Yufeng (xyufeng)]

Hi Paul,
You've helped me in the exact way. I just did not know where this syntax comes 
from. Now I know I can either use solaris make or change :sh= to $(shell).  

Thanks,
Xu

Help you out with what exactly?

The syntax you're referring to is a feature of the Solaris version of make.  It 
doesn't exist in GNU make.

If you don't want to change your makefiles, then you should continue to use the 
Solaris version of make and you won't have to.  But searching the GNU make 
manuals for information on using Solaris make will not, generally, be 
successful.  You need to find the documentation for Solaris make.
