build error for dependencies

[nerdneilsfield]

Hi, I trying to compile LibPSI in ubuntu 20.04 with AUTO_FETCH=ON, then I got those errors:

/home/dengqi/Source/langs/cpp/libPSI/thirdparty/libOTe/cryptoTools/thirdparty/relic/src/md/blake2.h:101:23:
    error: size of array element of type 'blake2s_state' (aka 'struct

    5 errors generated.

the error seems came from the relic library depended by cryptoTools, I try to update the tag of getRelic.cmake to the newest stable version of relic as 0.6.0. Then this error disappear , but there came another error forcryptoTools`:

libPSI/thirdparty/libOTe/cryptoTools/cryptoTools/Crypto/RCurve.cpp:230:9:
  fatal error: use of undeclared identifier 'bn_init'

          bn_init(mVal, static_cast<int>(sizeDigits()))
          ^

  1 error generated.

Then I try to update the version of cryptoTools, but it does not help, and will introduce another errors.

What system/OS are you on?

You can try to remove the "staged" version of relic.

rm -rf out/install
rm -rf thirdparty/libOTe/out/install

Just changing the commit won't restage relic and therefore you still might be on a old version? Maybe not though since it failed to compile in the first place...

You can also build libOTe with relic disabled and sodium enabled. This can be done in thirdparty/getLibOTe.cmake. But make sure it actually rebuild libOTe... e.g. remove out/ and thirdparty/libOTe/out/.

Thank you very much for your reply!

I am using Ubuntu 20.04 with clang-16 and gcc-11. For the above tests, I have already removed the output to test the newer version of Relic, but it still failed.

I will try to disable relic and use sodium for test.

Build libOTe with sodium support instead of relic.
