RE: [OctDev] Issue Building/Installing liboctave_fixed.dll.a

[Phillips, J. R <jam...@ho...>]

OK, here are some cygwin command-line queries and results:

$ cd /usr/local
$ find . -name liboctave.dll* -print
./bin/liboctave.dll
./lib/octave-2.1.60/liboctave.dll.a.2.1.60
./lib/octave-2.1.60/liboctave.dll.a
$ find . -name liboctave_fixed* -print
./bin/liboctave_fixed.dll
$ ld --version
GNU ld version 2.15.91 20040725
...
$ g++ --version
g++ (GCC) 3.3.3 (cygwin special)
...

These are the most recent stable versions of g++ and ld available from cygwin.

When using "make -k install", I didn't get appreciably different results than without the "-k" flag.  The install
basically quits copying files once it hits an error, even for subdirs other than main/fixed.  So to finish the install
successfully, it is still necessary to touch main/fixed/NOINSTALL, otherwise a lot of files not in main/fixed don't get
copied.

The *.dll.a is created by ld with the option --out-implib=$(FIXEDLIBTARGET).a
The fact that it isn't created, if there are no build errors, means that the
options of cygwin's ld have changed... Is there a liboctave.dll and a 
liboctave.dll.a for example? Is there even a liboctave_fixed.dll ?
What version of ld and g++ have you installed?

make -k install should force the install, and would at worst mean that
you couldn't use the fixed-point toolbox....

The last time I booted into windows was more than 6 months ago, and so 
it is difficult for me to debug this.. I suppose I'll have though no
promises of when I'll get on to it.. Can someone else who builds
with cygwin tell me if they get this error?
