The llvm-config linker options are baked into the ocaml library, which is good. But for the execution engine, that link line includes the full paths to some .o files. Those paths come from llvm-config, and they vary before and after installation. (Before install, they point into the source tree as you're seeing.) You could theoretically get working .cma's by somehow building the bindings against an installed llvm-config.</div><div><br class="webkit-block-placeholder"></div><div>LLVMers, what's the advantage to building .o files instead of .a's for these libs?</div><div><br class="webkit-block-placeholder"></div><blockquote class="webkit-indent-blockquote" style="margin: 0 0 0 40px; border: none; padding: 0px;">LLVMARM.o<br>LLVMAlpha.o<br>LLVMCBackend.o<br>LLVMCellSPU.o<br>LLVMExecutionEngine.o<br>LLVMIA64.o<br>LLVMInterpreter.o<br>LLVMJIT.o<br>LLVMMSIL.o<br>LLVMMips.o<br>LLVMPowerPC.o<br>LLVMSparc.o<br>LLVMX86.o</blockquote><div><div><div><br class="webkit-block-placeholder"></div><div>This wouldn't be a problem if these components used .a's instead, since ld's search paths are set up correctly.</div><div><br class="webkit-block-placeholder"></div><div>The options I see are:</div><div><br class="webkit-block-placeholder"></div><ul class="MailOutline"><li>Use archive libraries instead of objects for the above.</li><li>Link the above .o files into .a's just for the ocaml bindings.
