| # Helper makefile to link shared libraries in a portable way. |
| # This is much simpler than libtool, and hopefully not too error-prone. |
| # |
| # The following variables need to be set on the command line to build |
| # properly |
| |
| # CC contains the current compiler. This one MUST be defined |
| CC=cc |
| # LDFLAGS contains flags to be used when temporary object files (when building |
| # shared libraries) are created, or when an application is linked. |
| # SHARED_LDFLAGS contains flags to be used when the shared library is created. |
| LDFLAGS= |
| SHARED_LDFLAGS= |
| |
| # LIBNAME contains just the name of the library, without prefix ("lib" |
| # on Unix, "cyg" for certain forms under Cygwin...) or suffix (.a, .so, |
| # .dll, ...). This one MUST have a value when using this makefile to |
| # build shared libraries. |
| # For example, to build libfoo.so, you need to do the following: |
| #LIBNAME=foo |
| LIBNAME= |
| |
| # APPNAME contains just the name of the application, without suffix ("" |
| # on Unix, ".exe" on Windows, ...). This one MUST have a value when using |
| # this makefile to build applications. |
| # For example, to build foo, you need to do the following: |
| #APPNAME=foo |
| APPNAME= |
| |
| # OBJECTS contains all the object files to link together into the application. |
| # This must contain at least one object file. |
| #OBJECTS=foo.o |
| OBJECTS= |
| |
| # LIBEXTRAS contains extra modules to link together with the library. |
| # For example, if a second library, say libbar.a needs to be linked into |
| # libfoo.so, you need to do the following: |
| #LIBEXTRAS=libbar.a |
| # Note that this MUST be used when using the link_o targets, to hold the |
| # names of all object files that go into the target library. |
| LIBEXTRAS= |
| |
| # LIBVERSION contains the current version of the library. |
| # For example, to build libfoo.so.1.2, you need to do the following: |
| #LIBVERSION=1.2 |
| LIBVERSION= |
| |
| # LIBCOMPATVERSIONS contains the compatibility versions (a list) of |
| # the library. They MUST be in decreasing order. |
| # For example, if libfoo.so.1.2.1 is backward compatible with libfoo.so.1.2 |
| # and libfoo.so.1, you need to do the following: |
| #LIBCOMPATVERSIONS=1.2 1 |
| # Note that on systems that use sonames, the last number will appear as |
| # part of it. |
| # It's also possible, for systems that support it (Tru64, for example), |
| # to add extra compatibility info with more precision, by adding a second |
| # list of versions, separated from the first with a semicolon, like this: |
| #LIBCOMPATVERSIONS=1.2 1;1.2.0 1.1.2 1.1.1 1.1.0 1.0.0 |
| LIBCOMPATVERSIONS= |
| |
| # LIBDEPS contains all the flags necessary to cover all necessary |
| # dependencies to other libraries. |
| LIBDEPS= |
