Comment (by SimonKing):
The function `choose_patche()` of singular's spkg-install removes most of
the files in `$SRC/omalloc/` if we are in debug mode. However, the
cygwin64 patch tries to patch some files in that folder.
In addition to that, the cygwin64 patch says
{{{
+ifeq ($(SINGUNAME),x86_64-Win)
+SO_SUFFIX = dll
+MODULE_SUFFIX = dll
+LIBSINGULAR_FLAGS = -shared
+LIBSINGULAR_LIBS = -lsingfac -lsingcf -lntl -lreadline -lgmp -lomalloc
+endif
+
}}}
So, if one would try to build the debug version in 64 bit cygwin, then one
had -lomalloc, but that would not work, since omalloc is disabled on
purpose, for the debug version.
What to do? In principle, we could put an alternative version of the
cygwin64 patch into the patches/conditional folder, and if we are in debug
version, we could let `choose_patches()` replace the regular cygwin patch
version by the conditional version.
I will try to solve the problem accordingly, however, I have no windows
box. Hence, someone else needs to test if a debug version of singular
works in cygwin.
