for my Trusted Boot project with coreboot, I need to get the OpenSSL crypto library running with coreboot. I could get the modified elfboot.c compiled with the OpenSSL calls, but at the linking point with coreboot_ram.o it crashes because that has the option -nostdlibs. The library needs that standardlibs and without that option coreboot build will fail.
Here is the output:

I need that stdlibs, without it can't find my library.
No, stdlibs will not help. Your problem is that libcrypto is not linked in.
Any chance how i could get this running?
Make sure libcrypto gets linked in. Hint: with the paths you provided, it is very unlikely you get the right libcrypto.
