/* When compiling with GNU libtool on Windows, DLL_EXPORT is #defined
|
|
for compiling the shared-library code. In this case, we'll #define
|
|
FFTW_DLL to add dllexport attributes to the specified functions in
|
|
fftw3.h.
|
|
|
|
If we don't specify dllexport explicitly, then libtool
|
|
automatically exports all symbols. However, if we specify
|
|
dllexport explicitly for any functions, then libtool apparently
|
|
doesn't do any automatic exporting. (Not documented, grrr, but
|
|
this is the observed behavior with libtool 1.5.8.) Thus, using
|
|
this forces us to correctly dllexport every exported symbol, or
|
|
linking bench.exe will fail. This has the advantage of forcing
|
|
us to mark things correctly, which is necessary for other compilers
|
|
(such as MS VC++). */
