Re: [Tclxml-users] Problems building tclxml with expat on linux

[Forest W <lyr...@ww...>]

Andreas sent his build output to show that tclxml will build with
expat, which is good to know, but it doesn't really help me.  I'm not
doing an automated build with complex directory structure like he is.
I'm just following the build instructions in the README, and it
doesn't work on red hat 7.3.  Even with the copy of tclxml that I
checked out from CVS 30 minutes ago, "make all" in tclxml/expat fails
while trying to find .c and .h files that exist in the parent
directory.

As an experiment, I copied all the .c and .h files from the tclxml dir
to the expat dir, and tried "make" again.  It worked. =20

Another experiment:  I noticed that expat/Makefile sets the VPATH to
/..:$(srcdir)/xmltok:$(srcdir)/xmlwf:$(srcdir)/xmlparse
I removed the leading / so .. would be the first element in VPATH.
That worked too.

Okay, so it appears that the problem is that expat/Makefile doesn't
know how to find the files that live in the parent dir.  I don't
understand how it ever finds them, since that leading '/' in the VPATH
appears to be preventing it.  Is that '/' a bug?

Side note:  The README file refers to the --exec_prefix switch for
configure, while the configure help refers to --exec-prefix.  Notice
the difference between underscore and dash.  I guess configure may be
forgiving about this, but even if it is, the discrepency is confusing.
