similar to: [LLVMdev] klee linker problem

Hi, The klee library directory is determined at compile time and cannot be changed afterwards. Have a look at tools/klee/main.cpp to see how it is computed. I usually use Klee without any install step, right from the build directory. This has never given me the error you see. Hope this helps, Jonas On Wed, Jun 5, 2013 at 5:26 PM, Alexandru Ionut Diaconescu < alexandruionutdiaconescu at

Are there any "current" Linux distros that have installable packages for llvm, clang, nad klee? I am struggling to get klee built and need a working klee setup asap. Thanks in advance, Donald

Hi, I am trying to evaluate how complex would be to modify KLEE ( http://klee.llvm.org/ ) so that it can run LLVM bitcode compiled from Java code obtained with vmjc (from the VMKIT project). Your feedback will be very appreciated. I am familiar with KLEE but I would like to know more about VMKIT, so please point me to the right docs/source code if appropriate. After a quick look over

Hello, In my reading over the last couple of days, I have read that in order for klee to work with "native" Linux programs, I need to install the uClibc posix support for klee. I am not finding the uClibc source in the llvm svn repository anywhere. Is this still necessary for testing native Linux applications, and if so, where do I get the uClibc source to compile? Thanks in

Dear Developers, I am a Master's student at the ECE department of the University of Florida, USA.​​ For my research project, supervised by Prof. Mark Tehranipoor<http://tehranipoor.ece.ufl.edu/> and Prof. Farimah Farahmandi<http://farimah.ece.ufl.edu/>, I need to use Clang LLVM DataflowSanitizer library in KLEE. However, I have faced some difficulties (explained below) while

Hello, probably it is too late to be involved in GSoC, by I want discuss following idea: KLEE can generate tests only for main function level without any modifications of original code. It passes args specified by command line. I want implement automatic testcase generation for any imported function from tested code without its modification. First: parsing test code would collect input/output

Is there a possibility of accepting a KLEE project as an LLVM GSoC project? -- Aleksander "Alistra" Balicki email: balicki.aleksander at gmail.com jabber: wszystkie.inne.byly.zajete at gmail.com

Hi Andreas, Cloud9 is a project that has an extensive POSIX environment model which also lets you symbolically execute multithreaded programs. It is based on KLEE. http://dslab.epfl.ch/pubs/cloud9.pdf Portend builds on top of Cloud9 to perform race detection/classification: http://dslab.epfl.ch/pubs/portend.pdf Cloud9 code base is also public, it might be of interest to you:

Hi, I'm currently trying to find and fix memory leaks (compiling with ``-fsanitize=address``) in the KLEE tool [1] an having found some leaks and I'm having trouble suppressing them. I'm trying to suppress them using the ``-fsanitize-blacklist=blacklist.txt`` option as documented at [2]. I'm using Clang 3.7 ( Arch Linux package 3.7.0-6). The sort of reported leaks I see are ```

Hi all, I'm new to llvm and klee. Now I'm trying to build up coreutil with klee. Following the steps online (http://klee.llvm.org/TestingCoreutils.html), I went to step 3 and stuck. When I try to run: klee --libc=uclibc --posix-runtime ./cat.bc -version Error occurred like: klee: error: Cannot find linker input '/lib/libc.a' klee: ModuleUtil.cpp:42: llvm::Module*

Hi, I'm having problems compiling llvm-gcc-4.2-2.9 (from [1]). I need to use this version because I am trying to use KLEE (see [3]) which needs these versions. I am compiling on Arch Linux using gcc (GCC) 4.7.0 20120505 (prerelease) the output of `gcc -v` can be found at http://pastebin.com/8j2m3wzD I have tried the following 1. Extracted llvm-2.9 (from [2]) 2. Applied a patch (adds

When I try to execute the following example, I get an error message: /usr/local/lib/ruby/gems/1.8/gems/mocha-0.5.4/lib/mocha/object.rb:40: in `expects'': undefined method `stub'' for nil:NilClass (NoMethodError) from test8.rb:5 What could be the reason? I tried with the latest Mocha Ruby gem, and I also tried it with the Rails plugin. The example: require

Hi I need a concolic execution framework based on LLVM. As far as I know, KLEE might be the best choice. However, KLEE(the stable version) is based on LLVM 3.4. I compiled my code with the latest LLVM, whose version is 7.0. Anyone know whether the bitcode could be used by KLEE. Or do I have to compile with the old version of LLVM again. Furthermore, if you have any other concolic execution

Hi, We're currently upgrading KLEE to work with LLVM >=3.3 and we've hit a problem. It seems r172749 removed support for linking a bitcode archive into a module. KLEE unfortunately depends on this to link in its runtime ( which amongst other things provides a C library [5] ). A first attempt at linking in a bitcode archive ourselves can be seen in [1]. This approach does not work

Hi, I'm working on a tool (KLEE) that interprets LLVM bitcode. One of the things it does is it instruments the LLVM bitcode with checks for division by zero. It does this by injecting calls to a function "klee_div_zero_check(long long divisor)" just before every division instruction (e.g. SDiv). These checks are injected by a pass that has been implemented in KLEE. This

Thanks for your help, Wei-Ren and Anton. However since I am doing some experiments with klee( http://klee.llvm.org/GetStarted.html) and llvm-gcc seems to have better compatibility with it. So I still hope that I can use llvm-gcc:-) Hongxu Chen On Sat, Mar 16, 2013 at 3:35 PM, 陳韋任 (Wei-Ren Chen) [via LLVM] < ml-node+s1065342n56013h94 at n5.nabble.com> wrote: > Hi Chen, > >

Hi, I'm a contributor to the KLEE project (based on LLVM) and I'm currently looking at trying to add the following functionality to KLEE... (1). Be able to iterate through registered command line options and programmatically hide them. We're interested in this because we wish to hide (unless -help-hidden is called) several LLVM options. (2). Be able to place an option into a category
