Subject: Compiling with Cygwin64 in Win10: OpenCL library not found
Hi,
this is the first time using and compiling JTR, aswell as using cygwin64.
I haven't found any binaries with pfx2john.exe and John.exe that supports PFX/PKCS12 that also runs with CUDA enabled. So I have to compile it myself.
I mostly followed those explanations:
- http://openwall.info/wiki/john/tutorials/win64-howto-build
- http://openwall.info/wiki/john/GPU
In .bashrc I added the following lines:
- export GCC=gcc
- export PATH=$PATH:/usr/local/cuda/bin
- export LD_LIBRARY_PATH=:/usr/local/cuda/lib64
Beside that I had to link the libraries as following, or it would not even find the OpenCL headers. I don't know, if that approach is right or wrong, or could be done in a better way.
- ln -s /usr/local/cuda/include/CL /usr/include/
- ln -s /usr/local/cuda/include/CL /usr/include/OpenCL
But I am having a problem with compiling JTR with CUDA enabled. I installed the CUDA SDK and the header files are found. But for some reason, the library is not found. Could someone help me out, or point me to the right direction?
Thank you!
