Subject: [LLVMdev] LLVM out of source pass build: Loadable modules not<br>

Hi all,<br>
<br>
I compiled and installed LLVM from trunk on debian wheezy some weeks ago<br>
(configure & make) and now tried to out of source compile an opt pass<br>
following the cmake out of source pass build instructions from the docu.<br>
<br>
When trying to build (cMakeLists appended below)<br>
<br>
mkdir build<br>
cd build<br>
cmake -DCMAKE_MODULE_PATH=/usr/local/share/llvm/cmake ../<br>
<br>
I get:<br>
<br>
-- MyOutOfSourcePass ignored -- Loadable modules not supported on this<br>
platform.<br>
<br>
hmm? opt and the loadable passes (at<br>
llvm_trunk/build/Debug+Asserts/lib/xxx.so) are present and work (have been<br>
compiled using configure & make, not cmake).<br>
<br>
<br>
Any idea? Thx Alex<br>
<br>
<br>
P.S.:<br>
My questions are user questions and it seems to me the dev list is not<br>
appropriate. Please point me to the correct place if you feel the same and<br>
know where to discuss llvm user questions! Thx!<br>
