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

Question

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?

Solution

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.

[Gilles 'SO- stop being evil']

@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.
