I am having the same exact problem.  Has anyone figured out a solution
yet?

The generated Makefile for mono/mono/jit seems to contain definitions
for linking with glib but then they aren't actually used on the link
command line.  It's as if automake is finding the libraries properly,
but then it doesn't think that the JIT needs them to link - which is not
the case.

Here are the lines from the Makefile that seem relevant.  Libmono.la is
the target that fails to build.  I have reordered the definitions to
place them close to where they are used.

These defines seem relevant, but not actually used:

BASE_DEPENDENCIES_CFLAGS =  -I/home/aj/install/include/glib-2.0
-I/home/aj/install/lib/glib-2.0/include
BASE_DEPENDENCIES_LIBS =  -L/home/aj/install/lib -lglib-2.0 -lintl
-liconv
BUILD_GLIB_CFLAGS =  -I/home/aj/install/include/glib-2.0
-I/home/aj/install/lib/glib-2.0/include
BUILD_GLIB_LIBS =  -L/home/aj/install/lib -lglib-2.0 -lintl -liconv
GLIB_CFLAGS =  -I/home/aj/install/include/glib-2.0
-I/home/aj/install/lib/glib-2.0/include
GLIB_LIBS =  -L/home/aj/install/lib -lglib-2.0 -lintl -liconv
GMODULE_CFLAGS =  -I/home/aj/install/include/glib-2.0
-I/home/aj/install/lib/glib-2.0/include
GMODULE_LIBS =  -Wl,--export-dynamic  -L/home/aj/install/lib
-lgmodule-2.0 -lglib-2.0 -lintl -liconv
LIBC = libc.so.6
LIBOBJS =

These are the defines that are used, followed by the actual link line:

am__objects_1 = win32-exception.lo codegen-x86.lo emit-x86.lo regset.lo
\
        debug.lo debug-stabs.lo debug-dwarf2.lo jit.lo trampoline.lo \
        exception.lo linear-scan.lo helpers.lo
am_libmono_la_OBJECTS = $(am__objects_1)
libmono_la_OBJECTS = $(am_libmono_la_OBJECTS)
libmono_la_DEPENDENCIES = ../metadata/libmonoruntime.la \
        ../metadata/libmetadata.la ../io-layer/libwapi.la \
        ../utils/libmonoutils.la ../os/libmonoos.la
#libmono_la_DEPENDENCIES =
SHELL = /bin/bash
top_builddir = ../..
LIBTOOL = $(SHELL) $(top_builddir)/libtool
CC = gcc -mno-cygwin
CCLD = $(CC)
CFLAGS = -g -Wall -Wunused -Wmissing-prototypes -Wmissing-declarations
-Wstrict-prototypes  \
         -Wmissing-prototypes -Wnested-externs -Wpointer-arith
-Wno-cast-qual -Wcast-align -Wwrite-strings
LDFLAGS =  -L/home/aj/install/lib
LINK = $(LIBTOOL) --mode=link $(CCLD) $(AM_CFLAGS) $(CFLAGS) \
        $(AM_LDFLAGS) $(LDFLAGS) -o $@
prefix = D:/OpenSource/cygwin/home/aj/install
exec_prefix = ${prefix}
libdir = ${exec_prefix}/lib
srcdir = .
libmono_la_LDFLAGS = -Wl,-version-script=$(srcdir)/ldscript
libmono_la_LIBADD = \
        ../metadata/libmonoruntime.la   \
        ../metadata/libmetadata.la      \
        ../io-layer/libwapi.la          \
        ../utils/libmonoutils.la        \
        ../os/libmonoos.la
LIBS =  -lgc  -lws2_32 -lpsapi
libmono.la: $(libmono_la_OBJECTS) $(libmono_la_DEPENDENCIES)
        $(LINK) -rpath $(libdir) $(libmono_la_LDFLAGS)
$(libmono_la_OBJECTS) $(libmono_la_LIBADD) $(LIBS)


I fixed thousands of the missing symbols by changing LIBS to:

LIBS = $(GMODULE_LIBS) -lgc  -lws2_32 -lpsapi

But now I still have a few undefined symbols (e.g. __assert, __errno,
and _GC_malloc) and I do not know the correct incantations to fix them.

Does anyone know how I can either:
1.  Fix the build process so that it works properly, or
2.  Fix the Makefile so that I can at least get the JIT to link
manually.

Thanks,
Adam
