Default:
(if (eq (delivery-value :dll-exports) :no) :exe :dll)
image-type
defines whether the image is to be an executable or a dynamic library. The value can be :exe, :dll or :bundle. It defaults to
:exe
or
:dll
according to the value of
dll-exports
and therefore you do not normally need to supply
image-type
.
image-type
:bundle
is used only when saving a dynamic library. On Mac OS X it generates an object of type "Mach-O bundle" and is used for creating shared libraries that will be used by applications that cannot load dylibs (FileMaker for example). It also does not force the filename extension to be
dylib
. On other Unix-like systems
image-type
merely has the effect of not forcing the filename extension of the delivered image, and the format of the delivered image is the same as the default. On Microsoft Windows
image-type
:bundle
is ignored.
On Linux/Macintosh/FreeBSD
image-type
:bundle
requires that the build machine has a C compiler installed. This is typically
gcc
(available by installing Xcode on the Macintosh).
Note:
image-type
:bundle
is completely unrelated to the Mac OS X notion of an application bundle.
