#
# Specific settings for building shared libraries, static libraries,
# and bundles on various systems
#
#
# For each target, a few target-specific variables need to be set.
#
# The first one is SHARED_LIB_LINK_CMD - which should be set to the
# command(s) to use to link a shared library on that platform. Please
# note that the variables (stuff like $(LD)) in it are not expanded
# until SHARED_LIB_LINK_CMD is actually used (STATIC_LIB_LINK_CMD is
# the equivalent variable, used for static libraries).
#
# SHARED_LIB_LINK_CMD will be used to link standard shared libraries,
# and frameworks. It should use the following variables (which are set
# by library.make or framework.make before executing
# SHARED_LIB_LINK_CMD) to refer to what it needs to link (please note
# that STATIC_LIB_LINK_CMD will also use these variables with similar
# meanings; but not all of them, as noted):
#
# LIB_LINK_OBJ_DIR: where the newly created library should be.
# Usually GNUSTEP_OBJ_DIR for libraries, and FRAMEWORK_LIBRARY_DIR_NAME
# for frameworks.
# LIB_LINK_VERSION_FILE: the final file to create, having full
# version information: typically `libgnustep-base.so.1.5.3' for shared
# libraries, and `libgnustep-base.a' for static libraries. For DLL
# libraries, this is the import library libgnustep-base.dll.a. The
# reason we use the import library is because that is the code which
# needs to be installed in the library path. So by setting
# LIB_LINK_VERSION_FILE to the import library, the standard code to
# install it in the library path will work for Windows. The DLL
# library instead needs to be installed in the PATH, so we have separate
# code for that one.
# LIB_LINK_SONAME_FILE: this is only used for shared libraries; it
# should be passed in the -Wl,-soname argument of most linkers when
# building the LIB_LINK_VERSION_FILE. Typically `libgnustep-base.so.1'
# (but might also be `libgnustep-base.so.1.0' if INTERFACE_VERSION
# has been manually changed when using library.make). On many
# platforms, it's appropriate/standard to also create this file as
# a symlink to LIB_LINK_VERSION_FILE. If LIB_LINK_VERSION_FILE is
# the same as LIB_LINK_SONAME_FILE, then the symlink should not be
# created.
# LIB_LINK_FILE: this is only used for shared libraries; it should
# be created as a symlink to LIB_LINK_VERSION_FILE (or to
# LIB_LINK_SONAME_FILE if it's created on that platform).
# Typically `libgnustep-base.so'.
# LIB_LINK_INSTALL_NAME: on some platforms, when a shared library is
# linked, a default install name of the library is hardcoded into
# the library. This is that name.
# LIB_LINK_DLL_FILE: on Windows, this is the DLL that gets created
# and installed in the Tools/ directory (eg, gnustep-base.dll).
# Please note that while this is the main file you need to use the
# library at runtime, on Windows we treat this as a side-effect of
# the compilation; the compilation target for make is
# LIB_LINK_VERSION_FILE, which is the import library.
# AFTER_INSTALL_SHARED_LIB_CMD provides commands to be executed after
# installation (at least for libraries, not for frameworks at the
# moment), and is supposed to setup symlinks properly in the
# installation directory. It uses the same variables, except for
# LIB_LINK_INSTALL_DIR which is the full final path to where the
# library (and symlinks) is going to be installed.
#
# AFTER_INSTALL_STATIC_LIB_CMD is similar.
#
# For frameworks on unusual platforms, you might also need to set
# EXTRACT_CLASS_NAMES_COMMAND. This should be a command which is
# evaluated on $(object_file) and returns a list of classes
# implemented in the object_file. Our default command is the
# following (you can override it with another one in your target's
# section if you need), which runs 'nm' on the object file, and
# retrieve all symbols of the form __objc_class_name_NSObject which
# are not 'U' (undefined) ... an __objc_class_name_NSObject is defined
# in the module implementing the class, and referenced by all other
# modules needing to use the class. So if we have an
# __objc_class_name_XXX which is not 'U' (which would be a reference
# to a class implemented elsewhere), it must be a class implemented in
# this module.
#

# from A-Za-z0-9_. and Y is not 'U'. It then replaces the whole line
# with XXXX, and prints the result. '-n' disables automatic printing
# for portability, so we are sure we only print what we want on all
# platforms.

# rather than __objc_class_name_ so we search for either.
