I receive the following error when running an application under Mono 1.1.7 using DllImport:
in (wrapper managed-to-native) Haley.HaleyRules.DevelopmentKnowledgeBase:_InitializeKnowledgeBase4development (intptr,intptr,intptr,intptr,Haley.HaleyRules.KnowledgeBase/MemoryCallback,Haley.HaleyRules.KnowledgeBase/ExitCallback,Haley.HaleyRules.KnowledgeBase/WarningCallback,string,intptr,intptr,intptr,intptr,intptr) in <0x00069> Haley.HaleyRules.DevelopmentKnowledgeBase:.ctor (Haley.HaleyRules.WarningDelegate warningDelegate, System.Object theObject) in <0x001e7> HaleyRules.StandardAPItest.StandardAPItest:TestDevelopmentKnowledgeBase () Exception should not happen: System.NullReferenceException: Object reference not set to an instance of an object in <0x04221> HaleyRules.StandardAPItest.StandardAPItest:TestDevelopmentKnowledgeBase () in <0x00011> HaleyRules.StandardAPItest.StandardAPItest:Main (System.String[] args) The "Exception should not happen:" is an exception that wraps the actual exception in one of our regression tests (which actually has exceptions that should occur). The code works fine under Windows/.NET, the LD_LIBRARY_PATH is set appropriately to find the libraries, etc. The DLL containing the InitializeKnowledgeBase relies on other shared libraries that are also part of the project and under Mono 1.1.4 I could create a single library that reference the others and it would work then (definitely not ideal). Under 1.1.7 that trick doesn't work either. I also tried importing a function that just returned TRUE, but that caused the same error. I tried building the source and using GDB to track down the issue but that just caused Mono to throw a bunch of SIGTRAPs and GDB didn't handle it well. These are all C functions and not C++. Are there some compiler/loader flags that I am just missing? Thanks, Gary. _______________________________________________ Mono-devel-list mailing list [email protected] http://lists.ximian.com/mailman/listinfo/mono-devel-list
