    Current behaviour

    Building with the --with-experimental-kernel-lib configuration option currently leads to linker failures on OpenBSD 7.2. The following compiler/linker/build-tool versions are used:

    • clang 13.0.0
    • lld 13.0.0
    • ccache 4.6.3
    • GNU make 4.3
    • autoconf 2.71
    • automake 1.16.5

    Expected behaviour

    • Building should succeed

    Steps to reproduce

    $ ./configure --enable-suppress-external-warnings --with-experimental-kernel-lib MAKE=gmake
[ ... ]
$ gmake clean
$ gmake -j8

    This should help you resolve this issue, I had the same problem

    1. Add the -fPIC option to the CXXFLAGS and LDFLAGS variables in the Makefile generated by the configure script.

    2. Run "make clean" followed by "make" to rebuild the LevelDB library.

    3. Rebuild your application with the newly constructed LevelDB library.

    I believe this issue is no longer relevant after migrating to CMake.

    On OpenBSD 7.6, the build completes without any issues:

    $ cmake -B build -DBUILD_KERNEL_LIB=ON
$ cmake --build build
$ file build/src/kernel/libbitcoinkernel.so 
build/src/kernel/libbitcoinkernel.so: ELF 64-bit LSB shared object, x86-64, version 1

    Closing for now. A new issue can be opened, if this still happens on current master.
