### build_subdirs is the list of directories we actually want to
|
|
### build. It's not equivalent to existingdirs: if we can't find the
|
|
### Tcl libraries, then we don't want to build in gtcltk-lib.
|
|
###
|
|
### So why can't we just forget about gtcltk-lib altogether, and
|
|
### delete it from existingdirs, in that case? Well, in order for
|
|
### 'make dist' to work, we still need to configure gtcltk-lib, and
|
|
### the top-level Makefile needs to know it exists,
|
|
build_subdirs="${existingdirs}"
|
|
|
|
### Decide which directories to build; remove the ones we don't want
|
|
### from build_subdirs.
|
|
|
|
### On some systems, the Tcl library contains references to
|
|
### functions in the dynamic linker library, -ldl, so we may need
|
|
### to include that.
|
|
AC_CHECK_LIB(dl, dlopen)
|
|
|
|
### Use gtcltk-lib only if we seem to have Tcl installed on the
|
|
### system. We really should check for Tk as well, but that involves
|
|
### finding all the X libraries that we need to do a complete link.

### Write the list of survivors, the directories we do want to build,

|
### to a file in the top level, so the subdirectories' configuration
|
|
### scripts can find it. We don't want to pass the list in the
|
|
### environment, because the subdirectory configuration scripts can be
|
|
### run on their own.
