with V8.12, the -v Build
switch conveys to Build a notion of how the
Build should be run. There are currently three
optimized, and purify.
These command-line arguments are automatically converted arguments
for the confBLDVARIANT Build
macro. See confBLDVARIANT for a complete description of
what this command-line flag does:
-v debug creates define(`confBLDVARIANT', `DEBUG')
-v optimized creates define(`confBLDVARIANT', `OPTIMIZED')
-v purify creates define(`confBLDVARIANT', `PURIFY')
But note that as of V8.12.7 sendmail, this
-v switch affects only FreeBSD and Linux. It is
silently ignored for all other operating systems. Also note that
purify is not supported for any operating system.
Read the RELEASE_NOTES file supplied with the
sendmail source to see if more recent versions
support purify and other operating systems.
