similar to: [LLVMdev] LLVMHello example fails with "undefined symbol"

I just follow the tutorial: http://llvm.org/docs/WritingAnLLVMPass.html Actually it's not only my module, I used the LLVMHello.so (a sample module in the source tree) and get the crash (I didn't do anything :-P). ~t On Tue, Aug 12, 2014 at 12:57 AM, Eric Christopher <echristo at gmail.com> wrote: > Weird, it definitely shouldn't be crashing.

Hi all, I find all my passes are all broken with LLVM 3.4. Then I tried out the LLVMHello.so specified in the LLVM doc, http://llvm.org/docs/WritingAnLLVMPass.html and it also crashes. It seems all the functions in the pass do work, but LLVM crashes in the doFinalization() step. Does anyone know this problem? Thanks! Tianyin

The module is shipped with the source code, so it's from the developers (not me). The path in the source tree is: llvm-3.4.2.src/lib/Transforms/Hello After compiled LLVM *#./configure --prefix=XXX --with-binutils-include=/path-to-binutils-2.24/include --enable-debug-symbols --enable-debug-runtime --enable-assertions --disable-optimized; make; make install* LLVMHello.so is generated at

no... I guess verifier runs by default and it points to the doFinailization() function :-( ~t On Tue, Aug 12, 2014 at 12:53 AM, Eric Christopher <echristo at gmail.com> wrote: > No idea, I was suggesting to just run the verifier to see if it would > pinpoint what's broken about the module. > > -eric > > On Tue, Aug 12, 2014 at 12:52 AM, Tianyin Xu <tixu at

Oh, you mean opt -disable-verify? Yes, it does eliminate the crashing... Do you know what's the problem, Eric?

Hi, I'm making my way through the WritingAnLLVMPass tutorial and hitting the following issue. $ opt -load ../../../Debug+Asserts/lib/LLVMHello.so -hello < hello.bc > /dev/null opt: symbol lookup error: ../../../Debug+Asserts/lib/LLVMHello.so: undefined symbol: AnnotateHappensAfter nm -g ../../../Debug+Asserts/lib/LLVMHello.so U AnnotateHappensAfter ... $ ldd

Hi, what's the current state of being able to build simple analysis passes out-of-tree against only llvm headers and libraries with llvm-config? I see that clang and klee do not use llvm-config but for example rubinius does. Should both approaches be documented? Currently for example docs/WritingAnLLVMPass.html says "you need to create a new directory somewhere in the LLVM source

Has anyone seen this error before? I'm trying to load a pass that apparently isn't registered, it's just the "Hello World" sample , so I don't see the problem. Error: me at here:~/llvm/llvm_core/llvm-2.9$ opt -load Release/lib/LLVMHello.so -hello <cdfg.c> /dev/null Error opening 'Release/lib/LLVMHello.so': Release/lib/LLVMHello.so: undefined symbol:

Dear all, I'm new to the LLVM world and I'm trying to run reproduce the hello world example described here http://llvm.org/releases/3.8.1/docs/WritingAnLLVMPass.html. I started with a fresh new llvm-3.8.1 installation based on cmake (running on Linux x86) using the following command: cmake -DCMAKE_INSTALL_PREFIX=/path/to/llvm -DLLVM_TARGETS_TO_BUILD="X86" ../ The build

I'm working though http://llvm.org/docs/WritingAnLLVMPass.html, trying to write a very simple pass. I have followed all the steps mentioned in this document.But as mentioned I'm not getting any file named Hello.so in Debug+Asserts/lib folder(There is a file named LLVMHello.so only). I have also tried to modify Hello.cpp in lib/Transforms/Hello but these changes doesn't reflect

Hello, I am trying to compile the Hello Project of the lib/Transforms/Hello subdirectory according to the instructions given on http://llvm.cs.uiuc.edu/docs/WritingAnLLVMPass.html document. I am using 1.6cvs source to compile LLVM. The problem is that after running the Make file on the project, the Debug subdirectory contains .lo file in place of .so file. I need the .so file to use with opt

I recently had a problem creating LLVMHello. I used this CMake file #!/bin/sh # clangcmake.sh cmake -G "Eclipse CDT4 - Unix Makefiles" -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DCMAKE_BUILD_TYPE="Debug" -DCMAKE_ECLIPSE_VERSION=4.5 -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang ../llvm then I ran make LLVMHello and the build failed

Hi all I am trying hello pass in llvm. I have compiled and could generate LLVMHello.so but while giving the pass using opt i am getting below mentioned error. Command used: *opt-2.8 -load ../../cse231_project/llvm/llvm-2.9/Debug/lib/LLVMHello.so -hello < hello.bc* Error opening '../../cse231_project/llvm/llvm-2.9/Debug/lib/LLVMHello.so':

Hi, I have some questions about the compilation of the llvm. First, why the majority of the results of compilation are static library ( *.a files in the $(LLVM_HOME)/Release+Asserts/lib/), Why don't generate dynamic link library (.so files in the directory). The exception is the file libLTO.a and libLTO.so, why the library LTO were generated for static and dynamic both? How to control the

I've built LLVM/Clang from svn under Cygwin on Windows 7. I'd like to build on the LLVMHello pass example, however, when I try: $ cd $LLVM/lib/Transforms/Hello $ make I receive a large number of errors which start with: llvm[0]: Linking Debug+Asserts Loadable Module LLVMHello.dll /cygdrive/c/Users/Graham/home/projects/llvm_cygwin/lib/Transforms/Hello/Debug+Asserts/Hello.o: In function

Hi ! The Hello world pass sources are in llvm/lib/Transform/Hello/* If you compile llvm, the Hello library will be compiled too. It's not installed but it's in build_directory/Debug/lib/LLVMHello.so (or in build_directory/Release/lib/LLVMHello.so) Olivier.

When I build LLVM, the message LLVMHello ignored -- Loadable modules not supported on this platform is shown and the LLVM Hello pass doesn't work. I am using Windows. Is this correct? LLVM Hello pass works only on Linux? Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I was trying to write a LLVM Pass, so I first read http://llvm.org/docs/WritingAnLLVMPass.html#quickstart about how to write a llvm pass. Here, under setting up the build environment settings, it was instructed to configure and build LLVM directly inside the LLVM source tree rather than in a separate objects directory. Now, my LLVM source tree is C:\LLVM\llvm-2.9 while my build is in

Hello, everybody! On win32(s), lib/Transforms/Hello cannot be built cleanly. It will be built after 1st build. Linking the plugin LLVMHello.dll requires other libraries, especially LLVM.dll. May I move Hello to other location? Or, may I tweak llvm/Makefile? ...Takumi

For a while now I have noticed that when I build LLVM using CMake on my OS X machine there are two dynamically linked libraries, BugpointPasses and LLVMHello, that are built with the extension ".so" instead of the extension ".dylib". This has been causing four test cases to fail when running "make check". The attached patch modifies add_llvm_loadable_module in the
