cmake errors if openssl and ssh are installed in non default locations about netopeer2 HOT 7 OPEN

Observation1

Yes, this needed to be improved and I have added the commands as an alternative if the CURL target does not exist, should work for you now.

Observation2

You are right that netopeer2 is not linking OpenSSL nor libssh but the reason is that it is not using them so it is redundant to link them. Why do you need to link these libraries?

from netopeer2.

netopeer2-server links libnetconf2 which has dependency with OpenSSL and libssh. So building netopeer2-server require above mentioned changes to link OpenSSL and libssh libs.

from netopeer2.

No, libnetconf2 links its dependencies and any project linking libnetconf2 does not have to link its dependencies separately (you can easily verify this is how it always works in cmake, for all the libraries).

from netopeer2.

Thanks, i just reverified again.

Observed below linker issue if we do not provide OpenSSL (non-standard path) in netopeer2/CMakeLists.txt (target_link_libraries).

/usr/bin/ld: warning: libssl.so.3, needed by /root/netconf/bin/lib64/libnetconf2.so, not found (try using -rpath or -rpath-link)

OpenSSL libs are dynamically linked to libnetcon2 and are maintained in non-standard paths. So target_link_libraries step seems to be needed. Will check again if anything wrong in the generated 'link.txt'

from netopeer2.

I believe this is an error of libnetconf2 compilation, not netopeer2. Unfortunately, since libnetconf2 is just a dynamic library, its dependencies are not actually resolved until a binary is compiled that is actually using those functions (such as netopeer2). So you need to fix your libnetconf2 build.

from netopeer2.

Sure i will check if there is anything that need to be done in libnetcon2 build.

Dumps from libnetcon2 and netopeer2 builds are added below for reference. Apologies for adding complete build dump. Error is from netopeer2-server build. Pls ignore if this is some basic config issue. Will figure out why dependencies are not identified while building netopeer2-server.

/usr/bin/ld: warning: libssl.so.3, needed by /root/netconf/bin/lib64/libnetconf2.so, not found (try using -rpath or -rpath-link)

from netopeer2.

So netopeer2 log:

/usr/bin/ld: warning: libcrypto.so.3, needed by /root/libssh-0.9.5-build/lib64/libssh.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libssl.so.3, needed by /root/netconf/bin/lib64/libnetconf2.so, not found (try using -rpath or -rpath-link)

meaning libssh is not compiled properly, its OpenSSL dependency and libnetconf2 also with its OpenSSL dependency. In both cases, when specifying the cmake variables manually, you need to link all the OpenSSL libraries (libssl.so and libcrypto.so). In any case, these problems are not specific to our projects and I try to help whenever I can but please try to solve these on your own first (the errors are quite obvious) before asking for help.
