[MacOS] Cannot build taintgrind #22
Comments
|
Hi, taintgrind does not include the autogen.sh script, but uses the one that comes with valgrind. Did you install valgrind (http://valgrind.org)? |
|
@wmkhoo no I did not build valgrind because I already have the one installed from the repo (brew install valgrind)... Can I build from source in addition to the valgrind I already have or will that cause conflicts? Thanks. |
|
If you don't want to replace the default installation, you can install it at location you specify using 'configure --prefix=...', which is what the taintgrind installation instructions describe. |
|
@wmkhoo alright thank you. I got it working, but I just ended up using a Ubuntu VM which I use often anyway and then building everything from sources as specified. Now I just need to learn LLVM bytecode :P . I am familiar with x86-64 and C but I have not had to directly read/interpret LLVM bytecode. It is possible to lift it to C to find out which source lines are tainted? |
|
VEX, which is what valgrind uses, takes a little getting used to. However, if you include debugging symbols during compilation (e.g. gcc -g ...), taintgrind will list the source line. |
|
Let's try and get taintgrind to build on MacOS. |

I think you're right, these symbols should be defined in capstone library.

Seems to compile for me on High Sierra amd64. Someone else want to give it a go? |
Yeah I'll give it a shot and let you know the results... Might take me a few days though my workload has been very high lately :\ |
Please excuse my ignorance, but the instructions say:
[me@machine ~/valgrind-X.X.X] git clone http://github.com/wmkhoo/taintgrind.git
[me@machine ~/valgrind-X.X.X] cd taintgrind
[me@machine ~/valgrind-X.X.X/taintgrind] ../autogen.sh
[me@machine ~/valgrind-X.X.X/taintgrind] ./configure --prefix=
pwd/../inst[me@machine ~/valgrind-X.X.X/taintgrind] make && make install
However, there is no autogen.sh or configure in the repo. There's a configure.ac which I cannot get to run. I do have automake and autoconf but have not used these tools before.
