Yes, that's what the "export" keyword does: it tells make to put the variable into the environment when it invokes a command as part of a recipe. See the GNU make manual: http://www.gnu.org/software/make/manual/html_node/Variables_002fRecursion.html The only ways for one program to pass information to another program in UNIX are through the command line and through the environment (unless you want to use more complex and non-portable methods such as shared memory etc.) The export keyword tells make to put the variable into the environment. _______________________________________________ Help-make mailing list Help-make@gnu.org https://lists.gnu.org/mailman/listinfo/help-make
