This is a pkg-config issue, that is why cmake is not showing any more details. Make sure pkg-config can find libnetconf2 (its .pc file must be in the paths searched by pkg-config).

I have installed all dependent libs at path /home/mp1172/5g/mp1_y15_oc8.4/netoopeer2/

pkg_check_modules(PKG_LN2 REQUIRED libnetconf2) is the code throwing error.

yes linetconf2.pc is there at path , still issue, any direction or variable I need to add in cmake to change the package path

Thanks for your input.

Now it is done successfully.

Consider adjusting the PKG_CONFIG_PATH environment variable for other path than user/local.

$ pkg-config --cflags openssl

hi,

when BUILD_CLI=ON is there below error is coming.
GENERAL_NAME_free@@libcrypto.so.10 is not there anywhere in dependent libs, is there specific crypt library is required other than build manual ?

I believe you are cross-compiling and we do not officially provide support with that. We are not able to help with setting up your environment correctly anyway.

hi michal,

I am building at linux, and it is not cross comile.
In below cmake option let me know which is showing cross compile ? I will disbale it.

/usr/bin/ld: CMakeFiles/netopeer2-cli.dir/commands.c.o: undefined reference to symbol 'GENERAL_NAME_free@@libcrypto.so.10'

it looks CLI is looking for this, and it is there in my build machine still looks not able to fetch it.

This issue is visible in latest vetsion coming from december2024.

I am building at linux, and it is not cross comile.

I see, sorry then. It seems the CLI was not adjusted to work with mbedTLS and it still requires OpenSSL. Not strictly a problem but the version required is at least 3.0.0 but you are linking against 1.0.2k. Not sure how that happens as in the initial package list you have included OpenSSL 3.4.1. Make sure the CLI is linked with the recent OpenSSL version, then it should work. It should work by default but it seems you have several OpenSSL versions installed and the headers are not properly matched with the correct library version.

I tried to link with latest 3.4.0 Openssl, but looks CLI have some code which symbole is availale only in libssl.so.10 not in 3.4.0

Would you like to remove this libssl.so.10 from your setup and check CLI is working or not ?

I do not know how you got libssl.so.10 to link but it seems the file does not exist. That is the problem, nothing else. Our cmake script certainly does not add this requirement. You generally have a very messy setup, all the libraries should be found automatically (hence I thought you are doing a cross-compilation) so I am not sure I can help you much.

manmohanpatel2005 Apr 8, 2025

except CLI all other build happened successfully, so we can close this discussion.

It is not cross compile, it is pure Linux setup.
Looks cmake instllaed is not functoning proper, will try to have only one openssl and latest cmake.

Thanks a lot michal.
