Question

Is there a standard or good way of avoiding declared constants being named the same as a defined constant.

My Problem,

Im trying to compile my program using autoconf in linux which defines VERSION but in one of Mongo’s db header files they declare a constant named VERSION. There’s obviously a problem naming a variable using a right hand value.

Normally I would just change the name but in this case its not my library. I could figure out how to rename the defined variable autoconf.

Any suggestions?

You have to use no-define along with AM_INIT_AUTOMAKE in your configure.ac file.

By default this macro AC_DEFINE’s PACKAGE and VERSION. This can be
avoided by passing the no-define option, as in:

AM_INIT_AUTOMAKE([gnits 1.5 no-define dist-bzip2])

See Automake manual.
