Building Wallet example (from workspace) - throws <unknown>:0: error: could not build Objective-C module 'crypto' - 'openssl/e_os2.h' file not found about bitcoinkit

[johndpope]

think this is a side effect of the path not setup correctly on #3

/Users/johndpope/Documents/cryptoWorkspace/BitcoinKit/Libraries/crypto/include/openssl/bn.h:129:11: error: 'openssl/e_os2.h' file not found

include <openssl/e_os2.h>

[johndpope]

believe this is related to
carthage update --platform iOS --no-use-binaries

[johndpope]

going to try brew upgrade

@johndpope Can you make sure you’re using V0.1.1 or master? Homebrew is unlikely cause of the issue. libcrypto is built from source automatically as dependency

Errors Installing the "cryptography" Package
If you see the error shown below on OS X, then there was an issue installing the cryptography package.

build/temp.macosx-10.10-x86_64-2.7/_openssl.c:423:10: fatal error: 'openssl/e_os2.h' file not found
#include <openssl/e_os2.h>
To fix this issue, try upgrading Xcode Command Line Tools:

$ xcode-select --install
Then, make sure that openssl is installed and re-link it:

$ brew install openssl
$ brew link openssl --force

➜ BitcoinKit git:(btc) ✗ brew link --force openssl
Warning: Refusing to link: openssl
Linking keg-only openssl means you may end up linking against the insecure,
deprecated system OpenSSL while using the headers from Homebrew's openssl.
Instead, pass the full include/library paths to your compiler e.g.:
-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib

==> Caveats
A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
/usr/local/etc/openssl/certs

and run
/usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

If you need to have this software first in your PATH run:
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.zshrc

For compilers to find this software you may need to set:
LDFLAGS: -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include
For pkg-config to find this software you may need to set:
PKG_CONFIG_PATH: /usr/local/opt/openssl/lib/pkgconfig

No need to install OpenSSL to use this library. Can you try clone the repo then just build it?

[johndpope]

I'm on latest branch - bitcoinkit compiles fine - but with wallet - this is similar error I get.

I'm using iterm / zsh / mini conda - could have something to do with it.
will keep digging.

[johndpope]

joy. adding /usr/local/opt/openssl/include + /usr/local/opt/openssl/lib to header search path resolved this for me. not ideal I guess - but finally up and running.
happy to leave this open until a better solution arises.
or can close.

[kishikawakatsumi]

Hmm, it seems something wrong my side. I'll investigate it. Thank you for reporting!
