Yes this is true. Something like 'autoconf' or perhaps 'autoreconf' to generate the configure script. As the README in the plugin directory for UnicodePlugin indicates, an approach may be (it is a possibility) to use "pkg-config" Assuming that pkgconfig on your system gives some results such as: # pkg-config --cflags glib-2.0 # PKG_CONFIG_PATH=/usr/lib/64/pkgconfig pkg-config --cflags glib-2.0 it may be able to find the required --cflags using pkg-config However I can imagine that approach has its own disadvantages. My understanding is that historically pkg-config was used, and that the opensmalltalk-vm team wants to migrate/move away from pkg-config. If I'm not mistaken the Squeak VM "Classic" (squeak-4) uses the approach, with cmake/pkg-config. Squeak VM classic (in subversion) uses pkg-config. The GNU configure script could use also the same approach using: PKG_CHECK_MODULES(UNICODE_PLUGIN,[glib-2.0 pangocairo],,AC_PLUGIN_DISABLE) AC_SUBST(UNICODE_PLUGIN_CFLAGS) AC_SUBST(UNICODE_PLUGIN_LIBS) However I agree that no approach is without faults, they all have their own advantages and disadvantages, I suppose. Currently on Solaris 11.4 I just disable the UnicodePlugin, as it used to build fine for GNOME 2 (on OpenIndiana with MATE or Solaris 11.3), but not on GNOME 3 with 64bit (Solaris 11.4) for me. Provided I reconfigure with the right path to #include, UnicodePlugin builds, on Solaris 11.4 as well. This is basically unrelated to Solaris 11.3 or Solaris 11.4 etc. It is just where Linux/Unix distributions (or operating systems in general), put their #include files and the configuration tools to figure out the settings.

First sqPlatformSpecific.h provides platform implementations of prerequisites such as the EXPORT macros. Second sqPlatformSpecific.h defines platform specific support functions which need types declared by sqMemoryAccess.h. But sqMemoryAccess.h needs those platform implementations prerequisites first. So have sqMemoryAccess.h include sqPlatformSpecific.h a second time if it detects that sqPlatformSpecific.h has already been included, and have sqPlatformSpecific.h only declare the support funcitons if it detects that sqMemoryAccess.h has been included. A better solution would be to cleanly separate the two functions of sqPlatformSpecific.h but this is too much work in teh short term.

So so by moving the redefinition of EXPORT after a plugin's include files. The issue here is Windows' requirement to use declspec(dll_import) & declspec(dll_import) for sharing between exe and dll. To allow the VM to export warning and error to external plugins, warning and error must be correctly declared using the EXPORT macro. Hence these macros cannot be redefined until after the interpreters and any definitions in sqPlatformSpecific.h have been seen and applied. Further, so that sqPlatformSpecific.h *can* define EXPORT et al sq.h must include it before it attempts to provide default definitions of EXPORT et al and sq.h should never replace EXPORT et al if they have been defined. Further still, sqPlatformSpecific.h *cannot* be included before stdio if it is to "conveniently" define fseeko & ftello to the various 64-bit versions certain platforms require. Thankyou for understanding. The idea of sqCOnfig.h is perhaps in conflict with these changes. However, in my opinion it is much more important that we be able to build a complete VM on all platforms, including the ability to use asserts in external plugins, than it is for a convenient sqConfig.h to be usable. As previously discussed, C includes are white box and cannot reliably be prefixed with sqConfig.h unless we maintain each platform's sqConfig.h to apply to every possible version of a platform's include files, an obvious impossibility. I ask anyone wishing to alter the system here to please contact me and discuss before making changes. It is extraordinarily expensive and frustrating to have to make changes of this kind to make sure that a signfiicantly more complex VM such as Terf's builds correctly.
