Cmake Error

[nilslukas]

When running cmake .. in the build directory I get the following errors..

`CMake Error at CMakeLists.txt:26 (add_library):
Target "otextension" links to target "Boost::system" but the target was not
found. Perhaps a find_package() call is missing for an IMPORTED target, or
an ALIAS target is missing?

CMake Error at CMakeLists.txt:26 (add_library):
Target "otextension" links to target "Boost::thread" but the target was not
found. Perhaps a find_package() call is missing for an IMPORTED target, or
an ALIAS target is missing?

CMake Error at CMakeLists.txt:26 (add_library):
Target "otextension" links to target "RELIC::relic" but the target was not
found. Perhaps a find_package() call is missing for an IMPORTED target, or
an ALIAS target is missing?

I cannot reproduce this issue, neither on Manjaro nor on Ubuntu 19.04.

Can you try to do a fresh clone of the repository? What system are you using? Is boost installed? If yes, is the version at least 1.66?

I have this error, too

[dd23]

Please provide info about your system.
Did you try this with a fresh, unmodified clone of the repository?

@dd23 I have this error, too. Ubuntu 20.04LTS, boost version is 1.71.

Did you try this with a fresh, unmodified clone of the repository?

[WeiViming]

@dd23 Yes, It is fresh, unmodified clone of the repository. I have see another issue about this error. And add find_package(Boost 1.66.0 COMPONENTS system thread filesystem REQUIRED) into CMakeLists.txt. But it can not fix the last problem:

CMake Error at CMakeLists.txt:26 (add_library):
  Target "otextension" links to target "RELIC::relic" but the target was not
  found.  Perhaps a find_package() call is missing for an IMPORTED target, or
  an ALIAS target is missing?

Maybe you have an old version of ENCRYPTO_utils installed?
Can you check if cmake finds ENCRYPTO_utils, i.e., if it prints ""Found ENCRYPTO_utils".
What's the content of the extern folder? If there is an ENCRYPTO_utils folder in there - which versionis it?

[WeiViming]

@dd23 Sorry, I don't know how to see the version of ENCRYPTO_utils. But it prints "Found ENCRYPTO_utils". It is ok. The problem is wrong about "relic" library.. :'< Maybe I should find the reason about "relic". Thank you for your kindness! :)

[WeiViming]

I have solved this problem. The key point is remove the ENCRYPTO_utils from your system, and rebuild this project again. We will get this error if we have install the ENCRYPTO_utils by ourselves.
