Hash: SHA1
As requested by the readline package, here is a patch that enables dynamic
library compilation on cygwin, and should cause no change to other
platforms. The patch is against readline-5.1-alpha1, but should work with
little modification on readline-5.0 (as it is based on the cygwin-local
patch already used by the cygwin developers).
Background: On cygwin, (actually, Windows in general), the dynamic library
suffix must be .dll (not .so, and no numbers), and symlinks to dynamic
libraries don't work, so the version number of a .dll must appear prior to
the .dll suffix to distinguish API incompatible changes if the older
version is to remain around. Also, the .dll must be in the PATH, so .dlls
are generally placed in $(bindir), not $(libdir). However, for linking
against a .dll, the compiler looks for an export library in $(libdir),
rather than the .dll itself. Furthermore, cygwin prefers the prefix
cyg<name><vers>.dll over lib<name><vers>.dll, so that both cygwin and
mingw32 binaries can coexist in the same $(bindir), but uses
lib<name>.dll.a for the export library (so that programs being compiled
against readline always get the latest version when using -lreadline).
Historically, cygwin has already released API incompatible versions of
readline as cygreadline4.dll (4.x series, cygwin 1.3.x), cygreadline5.dll
(4.x series, cygwin 1.5.x), and cygreadline6.dll (5.x series, cygwin
1.5.x). Because API changes in both readline and in cygwin itself can
break compatibility, the dll version has exceeded the readline major
version number.
About the patch: To accomodate cyg<name><vers>.dll, it was necessary to
add SHLIB_LIBPRE to change the spelling of a library prefix; and
SHLIB_DLLVERSION which defaults to SHLIB_MAJOR, but can be overridden on
cygwin by setting $DLLVERSION in the environment before configuring. I
documented the effects of setting DLLVERSION in INSTALL, even though it
only affects cygwin compilation. I also changed the meaning of
SHLIB_LIBVERSION to include the leading dot if it is wanted, rather than
including the dot in SHARED_READLINE (all users have been updated),
because the cygwin spelling is the first case where the spelling does not
want a leading dot before the version number.
Both support/shobj-conf and shlib-install have sections added for cygwin,
then shlib/Makefile.in and configure.in are updated to propogate the new
variables in shobj-conf. shlib/Makefile.in is also patched to pass
$(bindir) on to shlib-install, since cygwin needs to know both bindir and
libdir.
