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

  • I'm trying to compile a program that, according to the documentation, requires the "OpenSSL library". I have OpenSSL installed, and it's still giving me the error openssl/sha.h: No such file or directory. Is there some other library that has to be installed?

    probably you are missing the openssl header files. depending on your distribution this package might have a different name, mostly it's something like openssl-dev or openssl-devel. after you installed the openssl header files, the compiler should be able to find openssl/sha.h.

    In Ubuntu/Debian the package is called libssl-dev.

    Turns out it was "libcurl4-openssl-dev". Not sure what libcurl has do do with SSL or SHA256, but it worked.

    @tkbx `/usr/include/openssl/sha.h` is in `libssl-dev` in oldstable, stable and unstable.

    FYI: I already had `libcurl4-openssl-dev` installed. `libssl-dev` sorted this for me.
