Re: Octave-3.3.54-source build on Cygwin

[Stewart Dickson]

OK,

I have installed cygwin::SuiteSparse, libSuiteSparse-devel and the 
latest updates to cygwin.
cygwin                          1.7.7-1
libSuiteSparse-devel            3.5.0-1
SuiteSparse                     3.5.0-1
gcc-core                        3.4.4-999
gcc-mingw-core                  20050522-1
gcc4                            4.3.4-3
gcc4-fortran                    4.3.4-3

On my system, I have no .../SuiteSparse/CXSparse/Include/cs.h
I have applied the patch you gave to /usr/local/src/CXSparse/Include/cs.h

I think that I must add CPPFLAGS=-D__CYGWIN__ to my configure line, 
because I think that gcc-4/cpp-4
does not add -D__CYGWIN__  automatically when uname -a => 
CYGWIN_NT-6.1-WOW64

'make' still produces the same error as below.

Thanks,
