I am trying to build Clang/LLVM with -DLLVM_BUILD_LLVM_DYLIB=ON and -DLLVM_LINK_LLVM_DYLIB=ON to reduce the size of toolchain. I am getting LINK error 1181 about `lib\LLVM.lib` not found. After investigating, `lib\LLVM.lib` is supposed to be produced along with `bin\LLVM.dll`. `bin\LLVM.dll` is indeed produced, but it does not contain any exported symbols (...

I ended up with libLLVM-3.9svn.so and libclang.so libclang.so.3.9 LLVM's shared lib naming looks wrong.

...rsioned libLLVMFooBar.so.3.7 and not against the unversioned library. This way when we ship the new libLLVM 3.8 old application will have to be recompiled to correctly link against the new LLVM LLVM 3.7 and before did this correctly and 3.8 should not break this. As I said in another mail I tried -DLLVM_BUILD_LLVM_DYLIB=ON -DLLVM_LINK_LLVM_DYLIB=ON but it's not currently usable as it is. Thanks, ismail

Using llvm 9, visual studio, HowToUseLLJIT.cpp It works fine in a release build. In a debug build It aborts due to an assert failure on Core.cpp (383) because the lhs flags are (Exported | Callable) and the rhs flags are (Callable). What mods should be made to fix this issue? Side note: The comments at the top reference HowToUseJIT.cpp rather than HotToUseLLJIT.cpp Thanks, Rob Conde

Now that autoconf is going away soon, I figured I'd try building using CMake. I checked out llvm, cfe and lldb from the SVN server, and followed the basic build instructions. cmake -DBUILD_SHARED_LIBS=OFF -DCMAKE_INSTALL_PREFIX=/tools/llvm/svn_head -DLLVM_TARGETS_TO_BUILD="X86;CppBackend" -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=ON ../llvm Everything worked well, and in

Hi, For lllvm 3.7 and before BUILD_SHARED_LIBS=ON would produce versioned shared libs like libLLVMLTO.so (symlink) libLLVMLTO.so.3.7 (symlink) libLLVMLTO.so.3.7.0 (real file) now it just builds an unversioned libLLVMLTO.so file which I believe is a problem because when a program links to llvm it generates a runtime dependency on libLLVMLTO.so instead of libLLVMLTO.so.3.7.0 which will break

Hey Guys, I'm working on a project in Android related to System-level Audio DSP Effects for Tuning Android Audio. I want to leverage Faust ( https://faust.grame.fr/) to allow users to program their own filters. Faust provides a libfaust implementation which includes a JIT Compiler which leverages LLVM and seems to be the best path for me to use. Unfortunately I'm having problems
