Hyper: openssl/ssl.h file not found when attemping to build

[fabioberger]

Hi there,

I just tried to compile my project after adding hyper as a dependency and received this error:

$ cargo build --release

Build failed, waiting for other jobs to finish...

Any help with how to resolve this would be greatly appreciated!

I ran into the same issue, installing a new version of OpenSSL worked for me, by for example running brew install openssl. And then adding the code below to your ~/.profile.

export OPENSSL_INCLUDE_DIR=`brew --prefix openssl`/include
export OPENSSL_LIB_DIR=`brew --prefix openssl`/lib

Basically the rust-openssl package needs headers > v1.0 (?) and the default ones in Mac OS are from version 0.9.8, see https://github.com/sfackler/rust-openssl#osx.

One thing to watch out for: the openssl environment variables need an absolute path since the openssl build runs in a different directory than where cargo is invoked. The same error is reported for relative paths as for openssl just being missing.

If you're running this on a Mac, you may want to use the security-framework feature instead. In the long term, this is my plan: https://github.com/hyperium/hyper/issues/907#issuecomment-255509020

I'm facing the same, although i download OPENSSL for windows (openssl-win64) nothing changed , still the same message "openssl/bn.h" no such file or directory .. any one can help , note: i am trying to run a cryptographic proof of data integrity written in C on windows8 machine ..

Needed apt install libssl-dev to fix this on Ubuntu, in addition to apt install openssl
