I mean the library path to your own .so you want to call with FFI I don't know if providing the absolute path as module name still work... Not sure at all. See http://www.squeakvm.org/cgi-bin/viewcvs.cgi/trunk/platforms/unix/vm/sqUnixE… In ioLoadModule, these lines indicate where your .so was searched for in previous version, but it is now obsolete (see the #if 1 , #else directive): if (( handle= tryLoading( "./", pluginName)) || (handle= tryLoadingPath("SQUEAK_PLUGIN_PATH", pluginName)) || (handle= tryLoading( VM_LIBDIR"/", pluginName)) || (handle= tryLoadingPath("LD_LIBRARY_PATH", pluginName)) || (handle= tryLoading( "", pluginName)) # if defined(VM_X11DIR) || (handle= tryLoading(VM_X11DIR"/", pluginName)) # endif ) return handle; Current version only tries: /* try loading {pluginPaths}/MODULE_PREFIX<name>MODULE_SUFFIX */ then: /* try dlopen()ing LIBRARY_PREFIX<name>LIBRARY_SUFFIX searching only the default locations modulo LD_LIBRARY_PATH et al */ I don't know where is defined the extern char *squeakPlugins; For the macros, it has to be some cmake thing: http://www.squeakvm.org/cgi-bin/viewcvs.cgi/trunk/platforms/unix/vm/config.… SET (CMAKE_SHARED_MODULE_PREFIX "so.") SET (CMAKE_SHARED_MODULE_SUFFIX "") so no chance to find your own lib with first alternative. For the second one, too late for me to track down, beside, I don't want to learn anything more about cmake ;).

Re: [Pharo-project] CollabActive book :)

by Tudor Girba

Thanks for pointing this out. Indeed something seems to be wrong in the configuration. I will have to look into this. I see that you worked on: http://book.pharo-project.org/book/Announcements A couple of notes: - urls should be lowercase - you should create book parts for each of the subsections because like this the table of contents works better, you can reference them afterwards an the latex generator will produce the right outcome Cheers, Doru On 7 Apr 2010, at 01:14, Simon Denier wrote: > > Also what is missing is the handy toolbar which provides buttons to > decorate the text with Pier syntax.

Also what is missing is the handy toolbar which provides buttons to decorate the text with Pier syntax. Useful when you are not a pro of the syntax. But I don't know how to install this widget.

Hi, is there some brief documentation for how to use the book engine? I am not a pier expert, i just get the basic ideas. I tried to add some new pages/sections using the add command, but it kept on logging me out to the front page. I could not work out whether these actions had any side-effect or not. If there are no docs, perhaps someone knowledgeable could just add a page, showing how to add a page... thanks, Mike
