So how does one do THAT with squeak? You don't. Your operating system does that for you. Well, the same lookup rules for that dependent library apply, I suppose. Do you have the gmp library installed in your system? Yes, not having all dependent libraries does raise that "external module not found" error, too. It can be confusing. Working with FFI requires knowledge about working with shared libraries in your operating system. It's one of those "leaky abstractions" where Squeak is -- understandably -- not able to hold your hand for all kinds of configurations out there. :-) You can try using a debug-build VM, which produces a more descriptive error log.

Message-ID: Yes, thanks. I’ve created a very simple test app using mpfr. However, in xcode, at least, I have to explicitly link in both libgmp.dylib and libmpfr.dylib , which are both aliases pointing to the actual libriaries containing the code. ALL the libraries of all types created by the MacPort and put into the macport directory have been copied into the resources via duplication rather than simply moving aliases around. I first referred to “libmpfr.dylib” — which is an aliias — but starting using libmpfr.6.dylib (what the alias points to) on the outside chance that it was the alias causing problems. I don’t see how the references to code in the gmp dylib found in the mpfr dylib are going to automatically resolve if xcode requires one to explicitly link both dylibs in order for something to compile and run. . My next test is to compile some absolutely trivial library without external references and see if I can get that to work. Thanks for your input.

Message-ID: You are correct and i figured out my problem. The mpfr dylib has hard-coded references to the libgmp.dylib that was in the original directory that macports compiled the mpfr.dylib into. I’ll need to do craig latta’s solution of allowing that library to work, OR redirect macports to compile into the Resources directory. This is going to make using Macports installed stuff rather difficult to use,m at least on Mac OS. Unless it is possible to tweak the dylib to redirect to the Resourses directory… And the answer is: not easily: http://lessons.livecode.com/m/4071/l/15029-linking-an-osx-external-bundle-with-a-dylib-library I’d have to figure out to manually compile the code and specify the build options at levels that aren’t exaclty relevent to my vision of a hello world implementation. (so much for sticking my toe in the water while recovering from a 5 year, near-fatal illness). Thanks for your advice, and you were spot on in what you thought was going on.

Message-ID: I realize that the test library works, but I can’t use ANY kind of library user specified/user made library for FFI with Squeak on Catalina OR Mojave, and I can’t tell what I am doing wrong. I let Craig Latta watch me, via screen sharing on skype, set up the whole thing from scratch, and his response was to start to coach me in how to create and use the VM with a c-debugger. So I don’t think I’m doing anything obviously wrong or at least Craig didn’t catch it while he watched. Still don’t have the VM working, so I thought I ask if anyone has actually done it lately? The FFIPrim libray is in a .bundle, which may or may not be signficiant to this issue.

Then click the link to the Squeak homepage. [cid:2c166367-d714-4cff-9462-875f57164736] Squeak forms its own subsystem that sparsely communicates with the host system (such as Linux). When it says "there is no web browser installed", it does not speak about the Browser you have installed in your host system but about the Browsers that are installed within Squeak. By default, Squeak does not contain any web browser, but there are several implementations available: * You could try Scamper for a pure-Squeak web browser implementation; but be warned, unfortunately, it does only support very basic web pages (forget about complicated CSS, YouTube, or JavaScript) and is very slow. * Another approach is MagicMouse which actually runs a Chromium instance in the host systems and renders the results in Squeak. Pro: Supports every web page and has reasonable speed. Con: No pure Squeak implementation, so you won't be able to benefit from Squeak's typical interactivity and explorability when browsing the web. But's is a really cool concept. * And if your only wish is to open the link in your host system, in the big darkness outside of Squeak, you could load ExternalWebBrowser (available on Squeak Map via the Tools Menu). It creates a connection to the host system and opens any clicked URL there. Please let me know if you have further questions!

Christof, I followed your link for ExternalWebBrowser and downloaded it. But...I realized that I am a long way from installing it. I did Smalltalk a long time ago (20+ years) on IBM's Visual Age and prior to that, Smalltalk/VDos. But Squeak is an unrecognizable monster compared to Smalltalk that long ago. I am totally lost. The only thing that looks familiar is the TerseGuide and it is readOnly. Back-in-the-day that info was the live content of the one and only hierarchy browser. I can find no current books on Squeak. So I am just shooting in the dark. I'll get back to you when I can ask an intelligent question. Sorry, but I sent this first to the beginners-request list. I hope you can untangle it there. -------------- next part -------------- An HTML attachment was scrubbed... URL:
