emp-toolkit / emp-pvc Goto Github PK

Hi Xiao Wang,
I want to install emp PVC on my work computer (Linux), but I have encountered some problems.

When I compile emp-pvc with cmake . I got the following error：

CMake Error at CMakeLists.txt:17 (include):
include could not find requested file:

/usr/local/cmake/common.cmake

CMake Error at CMakeLists.txt:18 (include):
include could not find requested file:

/usr/local/cmake/source_of_randomness.cmake

CMake Error at CMakeLists.txt:19 (include):
include could not find requested file:

/usr/local/cmake/threading.cmake

relic-toolkit is massively modified relic-toolkit/relic@5518ed1 , so that emp-tool, emp-ot, and emp-pvc should follow it.
See https://github.com/tell/emp-env and its Travis CI results for details.

Make install doesn't seem to work. Apparently "install" hasn't been defined in the makefile.
Also, I get the following error while I perform make.

relic is no longer the default ECC implementation. So this repo works only with commit 50c01ba99e5d257de05ef0e74ce6a0294a9ff471. Should update the installation procedure to use this commit.

As shown in travis

Following the installation process in emp-readme, emp-ot , emp-tools & emp-sh2pc are installed but when running cmake . & make to install emp-pvc I get the following error:

fatal error: emp-ot/table.h: No such file or directory
#include <emp-ot/table.h>
^~~~~~~~~~~~~~~~
The emp-ot repository does not contain any table.h file.
When I comment the include, I get the next error:

emp-pvc/internal_eva.h:5:10: fatal error: emp-ot/mextension_kos.h: No such file or directory
#include <emp-ot/mextension_kos.h>

So it seems emp-pvc is using some old references. Any fix possible?

I'm trying to convert a semihonest code to pvc code. I had moved all the initialization before the TPCF_OT_ONLY flag, however that doesn't seem to working. The circuit inputs are still being initialized to some random values. Also, printing the circuit output (using reveal) doesn't seem to be getting the right output (even for the test examples). Do the input and output values needs to be dealt with in a different manner?

Hello，I had a problem testing the program locally when I input bin/test_pvc.cpp_exe sha1 alice & bin/test_pvc.cpp_exe sha1 bob

emp-pvc appears to be almost as slow as ag2pc over 32 core LAN machines. Is it because of the more efficient multi-threaded implementation of ag2pc over pvc?

The second link failed during installation, how to Install relic using script ?
