Linux: make vanitygen oclvanitygen OSX: make -f Makefile.osx vanitygen oclvanitygen Windows: Tools: Microsoft Visual Studio 2010, Visual C++ Prerequisites: - OpenSSL 1.0.0d: http://www.slproweb.com/products/Win32OpenSSL.html - pthreads-Win32: http://sourceware.org/pthreads-win32/ - PCRE: http://www.psyon.org/projects/pcre-win32/ - AMD APP SDK -or- NVIDIA CUDA SDK Once you have set up these components, edit the following variables in Makefile.Win32 to reflect the paths where these components were installed: OPENSSL_DIR PTHREADS_DIR PCRE_DIR OPENCL_DIR Note that pthreads and PCRE may be built as static libraries or DLLs. The default Makefile.Win32 includes CFLAGS required to link the static versions of those libraries. If you want to link against DLLs, make sure to change the CFLAGS. Additionally, to create a usable static build of the pthreads-Win32 library, some other changes must be done. You must edit the Makefile, and remove "/MD" from the CFLAGS. Then, build with: "nmake VC-static" After dependencies have been prepared, open a Visual Studio command prompt window, and run: nmake /fMakefile.Win32 vanitygen.exe oclvanitygen.exe
