It should work using getsectdatafromheader, that's what I changed when I added support for dynamic libraries to Tango. Have a look at the Tango code:
http://dsource.org/projects/tango/browser/trunk/tango/core/rt/compiler/dmd/object_.d#L1270 and http://dsource.org/projects/tango/browser/trunk/tango/core/rt/compiler/dmd/darwin/Image.d#L103 . The file in the last link is completely made by me so you won't have to be afraid for looking at it. Or if you don't want to look at Tango source files at all you can look at this druntime change: http://www.dsource.org/projects/druntime/changeset/372 , to be more specific: http://www.dsource.org/projects/druntime/browser/trunk/src/rt/image.d?rev=372#L105 On 9 nov 2010, at 00:26, Michel Fortin wrote: > Le 2010-11-08 à 17:12, Walter Bright a écrit : > >> See my reply: http://d.puremagic.com/issues/show_bug.cgi?id=4854 > > As a side note, I discovered this week that the Objective-C runtime also > depends on knowing the size of a section to initialize itself properly.
