Hello, I have started working on a client server system in C++ for privacy preserving signal processing applications. Since this system will rely on certain public key cryptography primitives, I decided to try and implement them with MPIR, since GMP seems a bit more complicated to compile on Windows... In this (long) message, I will detail my current progress with MPIR, the inconsistencies / errors that I noticed and, at the end, some questions.
At the moment, I downloaded mpir-2.5.1 and I think I managed to build the library for x64 and the SandyBridge platform - dll_mpir_sandybridge (I'm working on a Core i5 SandyBridge). In order to do this, I had to run the build.vc10\mpir_config.py (need to cd to \build.vc10\ before running it) in order to create the dll and lib projects for this platform (by the way, \build.vc10\readme.txt says to use "mpir_build.py" which does not exist). Afterwards, from the VS GUI, I had some issue with the prebuild.bat script, because you need to add the path for the sandybridge option into it in order to build this project, so I added this line: if /i "%1" EQU "sandybridge" ((set sdir=x86_64w\sandybridge) & (set platform=x64)) (hopefully, I got it right) After this, I noticed some inconsistencies in the documentation concerning the way it creates directories: - \dll\x64\Release - \lib\x64\Release - \build.vc10\x64\Release - the build.vc10\lib and \build.vc10\dll remain empty Afterwards, I decided to build the tests, to check if all went OK. For this, I build the lib_mpir_cxx project first (mpir-tests.sln it nags about a missing mpirxx.h without it). Sometimes, it throws build errors for certain test projects (regarding missing add-test-lib). I managed to get all of them to build correctly only after running build on add-test-lib and then (re)building those that fail one by one. I think it has something to do with the build order and some concurrency issues. Can they be built in batch mode without involving VS? I went to the \build.vc10\mpir-tests directory and ran run-tests.py. I got an error: no such file or directory '..\\dll\\x64\\Release\\mpir.dll at line 33. From what I can tell, the path there is wrong, probably because of the directory inconsistencies I mentioned above. I corrected it and got that 182 tests ran correctly (some were skipped with message "test suppressed for windows DLL"). \build.vc10\readme.txt mentions a last_build.txt generated in \build.vc10\, but I am unable to find it. Perhaps this functionality got removed... Questions: - I don't have that much experience in designing and writing (multiplatform) C++ applications from scratch and I was wondering if there is any article or book that helps in this sense or maybe some project that I could, at least, use as inspiration; - I saw that GMP has also added a C++ class interface. Is it compatible with the MPIR one? - The documentation states that "MPIR does not support the secure cryptographic functions provided by GMP". Could you please detail this statement? - For the client - server communication part, I think that OpenSSL is a good choice, which, as far as I've read, can be configured to use GMP as a big number library. Does this mean that I can use it with MPIR as well? Is there any guide on how to do this? - Since MPIR is forked from GMP to make it more Windows friendly, does this create any issues under Linux? At the moment, I am thinking of trying to use a Linux virtual machine for tests on my current platform. Are there any issues with running this library in a virtual machine? -- You received this message because you are subscribed to the Google Groups "mpir-devel" group.
