[help-3dldf] Re: Fwd: building issue

The problem was in `[...]/CWEB/Makefile.am'.

I have changed the lines

CWEAVE = cweav3DL 
CTANGLE = ctang3DL

to

CWEAVE = ./cweav3DL 
CTANGLE = ./ctang3DL

I've updated this on Savannah and in the snapshot.

cweave is irrelevant here, but ctangle is needed to generate C++ code from 
scanner2.web.  Some of the default limits of ctangle and cweave are too small 
for the sources of 3dldf, so it's necessary to generate versions of them with 
higher limits, namely cweav3DL and ctang3DL.  `scanner2.web' is the only CWEB 
file for which ctang3DL is called directly, so the problem (i.e., working 
directory not in `PATH') only occurred for this file.

The order in which the actions specified in the various `Makefile.am' files is 
important, so I wouldn't expect this to work.

After trying `make -j' (which failed), it was not sufficient to run `make'.  I 
had to run `make clean' and `configure' again.  After this, `make' succeeded.

Thank you for the bug report and please let me know if you have more problems 
building the package.
