Hi, I follow the step of seed official tutorial.
When I trying to compile the kernel, there is some error message shows up.
After typing make CROSS_COMPILE=riscv64-linux-gnu- ARCH=riscv -j8
there are some error:

scripts/extract-cert.c:21:10: fatal error: openssl/bio.h: No such file or directory
21 | #include <openssl/bio.h>
| ^~~~~~~~~~~~~~~
compilation terminated.
make[1]: *** [scripts/Makefile.host:95: scripts/extract-cert] Error 1
make[1]: *** Waiting for unfinished jobs....

scripts/sign-file.c:25:10: fatal error: openssl/opensslv.h: No such file or directory
25 | #include <openssl/opensslv.h>
| ^~~~~~~~~~~~~~~~~~~~
compilation terminated.
make[1]: *** [scripts/Makefile.host:95: scripts/sign-file] Error 1

Seems like I missed some files so the make process is terminated.
Is there anything I missed?

OK I find the solution.
I missed the package named: libssl-dev
After installing it the error is resolve.
