[OpenSmalltalk/opensmalltalk-vm] int-sqInt inconsistencies (#465)
by smalltalking 27 Mar '20

27 Mar '20

Some type declarations were not changed from int to sqInt, so now there are some inconsistencies, which are detected when compiling the 64-bit VM with LTO enabled. The following functions are affected: - primInIOProcessEventsFlagAddress - ioGatherEntropy - GetAttributeString - primitivePluginBrowserReady - primitivePluginDestroyRequest - primitivePluginRequestFileHandle - primitivePluginRequestState - primitivePluginRequestURL - primitivePluginRequestURLStream - primitivePluginPostURL -- You are receiving this because you are subscribed to this thread.

Selecting distributed plugins
by Nicolas Cellier 03 Mar '20

03 Mar '20

Hi all, Robert kindly asked me whether it would be possible to include DES and MD5 plugins in OpenSmalltalk VM distribution. We currently generate src/plugins code for those 2, but don't compile them. This raises the question: who decides which plugin gets included/compiled/distributed or not? On which criterion?

Therefore, it is no longer necessary to swap the MainMenu.nib files during the bundling of Squeak. Instead, we can keep the existing file (and therefore, it will stay in sync with OSVM changes).
