Thank you, Reid.
I have applied tha patch to ltdl.c ltdl.h. The problem still exists. I
looked up the symbol on libLLVMCore.a, and found three U-entries and one
T-entry. However, the Darwin linker is not able to find the T-entry. Any
idea?

I don't have a Mac so I can't replicate your situation. The Apple guys will be working tomorrow, so hopefully they can take a look at it.> pollux:~/test jingyu$ opt > -load /Users/jingyu/tools/build-ppc/Release/lib/LLVMHello.so -help > Error opening > '/Users/jingyu/tools/build-ppc/Release/lib/LLVMHello.so': Can't > open :/Users/jingyu/tools/build-ppc/Release/lib/LLVMHello.so: > dlopen(/Users/jingyu/tools/build-ppc/Release/lib/LLVMHello.so, 9): > Symbol not > found:__ZN4llvm12FunctionPass16addToPassManagerEPNS_20FunctionPassManagerTERNS_13AnalysisUsageE > Referenced > from: /Users/jingyu/tools/build-ppc/Release/lib/LLVMHello.so > Expected in: flat namespaceOh, one other thing you could try. Add LLVMCore.a to the USED_LIBS line in the lib/Transforms/Hello/Makefile file. This should link the addToPassManager method into the shared object, which might allow the pass to register.> pollux:~/tools/build-ppc/Release/lib jingyu$ nm libLLVMCore.a | grep > __ZN4llvm12FunctionPass16addToPassManagerEPNS_20FunctionPassManagerTERNS_13AnalysisUsageE > U > __ZN4llvm12FunctionPass16addToPassManagerEPNS_20FunctionPassManagerTERNS_13AnalysisUsageE > U > __ZN4llvm12FunctionPass16addToPassManagerEPNS_20FunctionPassManagerTERNS_13AnalysisUsageE > 00004100 T > __ZN4llvm12FunctionPass16addToPassManagerEPNS_20FunctionPassManagerTERNS_13AnalysisUsageEYes, this is the definition of the symbol. Not sure why the linker can't find it. I think on Darwin the runtime loader can't open the executable. But, I thought that problem was resolved with the ltdl.{c,h} change that you already implemented. As I said before, you're going to need some help from someone that knows Darwin better than I do.> 000197d8 S > __ZN4llvm12FunctionPass16addToPassManagerEPNS_20FunctionPassManagerTERNS_13AnalysisUsageE.eh > U > __ZN4llvm12FunctionPass16addToPassManagerEPNS_20FunctionPassManagerTERNS_13AnalysisUsageE > > > JingReid.

Using plain nm on my local one yields: 00121a4e T __ZN4llvm12FunctionPass16addToPassManagerEPNS_20FunctionPassManagerTERNS_13AnalysisUsageE and nm -m shows: 00121a4e (__TEXT,__text) external __ZN4llvm12FunctionPass16addToPassManagerEPNS_20FunctionPassManagerTERNS_13AnalysisUsageE Is this what you're seeing?

I am using llvm 1.8 and have patched ltdl.c and ltdl.h to the latest version.
