Can't add libp2p to project using hunter( libp2p versions available: [] [hunter ** INTERNAL **] Unexpected empty string) #138
Comments
same here. |
so do I. |
Okay, I think I (might) know what's going wrong here: "FindOpenSSL.cmake" line ~303 Here, a regex match attempts to extract the version number from "openssl/opensslv.h".
Investigating, it appears some versions of OpenSSL (perhaps newer ones), this fails. The regex expects something like this: However, it instead encounters this:
Consequently, the extracted version number ends up being empty. (Note: I am using OPENSSL_VERSION_STR "3.1.3") PS:
... not the best, but it looks like things are building now. |
You need to specify where it can get the version from: Change your cmake to this:
(add the local keyword in HunterGate to specify locally where huntergate can get the packages). Then add a config.cmake in a Hunter folder, which should be in the same folder as your HunterGate.cmake (so cmake/Hunter/config.cmake for you) and write:
This fixed it for me (might have to play with the hashes a bit, as in the SHA1 value). Also this for me fixed the issue above BUT lead me into another list of issues, which I can't even fix. |
I followed your suggestions #138 (comment) and I'm getting this bunch of errors :
How to make it work? |
download HunterGate.cmake,
in main CMakeLists.txt
then I try to make project using command
