If you see above ldconfig shows oatpp present but when compiled with -loatpp it doesn't work. Btw please note if I give -L path it works, if I have to do so then I needn't drop a .conf for this ld.conf.d.

Btw Below Works where I have given -L:
root@localhost ~/example-async-api/build (master) $ g++ -L /usr/local/lib64/oatpp-0.19.6 -I ../src/ -I /usr/local/include/oatpp-0.19.6/oatpp -loatpp ../src/App.cpp
root@localhost ~/example-async-api/build (master) $


I want this to work without giving Library path any help on the same ?.

Why not try If it doesn't show, you may get out with a symlink. Grok the code.

root@localhost /data/bkannadassan/core/hng (balaji_dib_docker) $ ldconfig -p | grep oat
liboatpp.so (libc6,x86-64) => /usr/local/lib64/oatpp-0.19.6/liboatpp.so

Please note above is a make file error.

That wasn't quite it. Here's your error: I must confess I don't follow that first line, probably because there's no context. At this stage, I would do a rm -rf on the tarball, start again, and try running it with no configure options. If it compiles, don't install it. You can always do a 'make clean' and put your configure options in.
