How to use SHA256 in a QEMU device

[Weiss, Howard]

I am writing a device which uses SHA256

 

I use the following to configure the build

 

   ./configure –target-list=x86_64-softmmu –enable-sdl –enable-debug –extra-ldflags=”’pkg-config –libs openssl’”

 

With PKG_CONFIG_PATH is defined via

 

  export PKG_CONFIG_PATH=/usr/local/openssl-1.1.1c

 

 

How do I correctly incorporate the SHA256 h files in the C source for driver

 

I have tried

 

  #include <openssl/sha.h>

 

but this results in a build failure

 

  fatal error: openssl.sha.h: No such file or directory

 

I even went so far as to copy the include folder for opensl-1.1.1c to qemu/include/opensll and convert all the #include <…> to #include “…”.  I can then change my c source to #include “openssl/sha.h” and the device builds but it then fails to link with undefined reference to the various SHA… modules

 

I read an earlier post with suggest including -lssl and -lcrypto in the –extra-cflags and –extra-ldflags options in ./configure but this did not work because -lcrypto is not defined

 

Please advise;

 

PS: Is there a description of the configure process and its options?
