# This is a Makefile stub which handles the creation of Linux DLL-style shared
# libraries.
#
# In order to use this stub, the following makefile variables must be defined.
#
# DLL_ADDRESS = 0x80000000
# DLL_JUMPSIZE = 0x1000
# DLL_GOTSIZE = 0x1000
# DLL_VERSION = 1.0
# DLL_IMAGE = libce
# DLL_STUB = libcom_err
# DLL_MYDIR = et
# DLL_INSTALL_DIR = $(SHLIBDIR)

# This is a horrible hack to try to find libgcc.a --- the DLL documentation
# states that you should just be able to do -lgcc, but modern gcc
# installation packages don't install /usr/lib/libgcc.a --- as well they
# shouldn't since libgcc.a can be gcc version dependent.
# If this hack doesn't work, try replacing it with a hardcoded path to
# libgcc.a, or -lgcc.

#DLL_LIBGCC ="`$(CC) -v 2>&1 | head -1 | \
# sed -e 's;[^/]*;;' -e 's/specs/libgcc.a/'`"
