- Subject: Using and detecting environment variables as flags
Hello, I want to be able to read/check the value of an environment
variable in my Makefile.am. This would be a variable that I set as part
of the an [action-if-found] in the AC_SEARCH_LIBS method, that I set in
configure.ac.
How do I reference such a variable?
In addition, depending on the value of this variable, I then want to
pass a signal from my Makefile.am to yet another Makefile which is
called from Makefile.am. This signal is to tell the second Makefile to
add an -lz in its LIBS definition.
How do I do this? In what way can I send such a flag/signal?
Thank You,
John
