[Buildroot] question: used wrong librarys to build packages

[Stefan Müller]

Hi guys

how is it possible that buildroot builds packages and links them against libraries that do not exist in buildroot (only on the host system, not below the buildroot directory)? - i am a bit confused now.
i downloaded buildroot 2024.02.01 and just copied my configs into it.

many of the built packages are now linked against libssl.so.1.1 (but buidroot uses openssl 3):
example:
build at build:~/buildroot/output/target/usr/sbin$ ldd NetworkManager
./NetworkManager: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by ./NetworkManager)
./NetworkManager: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./NetworkManager)
./NetworkManager: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by ./NetworkManager)
./NetworkManager: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.38' not found (required by ./NetworkManager)
        linux-vdso.so.1 (0x00007ffe9f755000)
        libgio-2.0.so.0 => /lib/x86_64-linux-gnu/libgio-2.0.so.0 (0x00007f2b90e93000)
<snip>
...
<snip>
        libssh.so.4 => /lib/x86_64-linux-gnu/libssh.so.4 (0x00007f2b9040d000)
        libpsl.so.5 => /lib/x86_64-linux-gnu/libpsl.so.5 (0x00007f2b903fa000)
        libssl.so.1.1 => /lib/x86_64-linux-gnu/libssl.so.1.1 (0x00007f2b90367000)
        libcrypto.so.1.1 => /lib/x86_64-linux-gnu/libcrypto.so.1.1 (0x00007f2b90090000)

but:
build at build:~/buildroot/output/target/usr/sbin$ find ../../../host/ -name libssl*
../../../host/x86_64-buildroot-linux-gnu/sysroot/usr/lib/pkgconfig/libssl.pc
../../../host/x86_64-buildroot-linux-gnu/sysroot/usr/lib/libssl.so.3
../../../host/x86_64-buildroot-linux-gnu/sysroot/usr/lib/libssl.so
../../../host/x86_64-buildroot-linux-gnu/sysroot/usr/lib/libssl.a
../../../host/lib/pkgconfig/libssl.pc
../../../host/lib/libssl.so.3
../../../host/lib/libssl.so
../../../host/lib/libssl.a
build at build:~/buildroot/output/target/usr/sbin$

and (host system that runs buildroot):
build at build:~/buildroot/output/target/usr/sbin$ find /usr -name libssl*
/usr/lib/x86_64-linux-gnu/pkgconfig/libssl.pc
/usr/lib/x86_64-linux-gnu/libssl.so
/usr/lib/x86_64-linux-gnu/libssl.so.1.1
/usr/lib/x86_64-linux-gnu/libssl.a
/usr/lib/x86_64-linux-gnu/libssl3.so
/usr/share/doc/libssl1.1
/usr/share/doc/libssl-dev
build at build:~/buildroot/output/target/usr/sbin$

shouldn't buildroot use the libraries that are inside the buildroot directory?
Can anyone help me find out what is wrong?
thanks
