[LLVMdev] LLVM out of source pass build: Loadable modules not supported (on Linux)

[Alexander Poddey]

Hi all,

I compiled and installed LLVM from trunk on debian wheezy some weeks ago 
(configure & make) and now tried to out of source compile an opt pass 
following the cmake out of source pass build instructions from the docu.

When trying to build (cMakeLists appended below)

mkdir build
cd build
cmake -DCMAKE_MODULE_PATH=/usr/local/share/llvm/cmake ../

I get:

-- MyOutOfSourcePass ignored -- Loadable modules not supported on this 
platform.

hmm? opt and the loadable passes (at 
llvm_trunk/build/Debug+Asserts/lib/xxx.so) are present and work (have been 
compiled using configure & make, not cmake).


Any idea? Thx Alex


P.S.:
My questions are user questions and it seems to me the dev list is not 
appropriate. Please point me to the correct place if you feel the same and 
know where to discuss llvm user questions! Thx!
