error: failed to run custom build command for `openssl v0.9.24`

问题

I want to install cargo-apk cargo install cargo-apk to my system (Linux Mint), but I'm getting this error

error: failed to run custom build command for `openssl v0.9.24`

Caused by:

I found that I should install libssl-dev, so I did, but it didn't help.

回答1:

rust openssl-sys library needs openssl installed.

then on Windows : download and install it from here first : http://slproweb.com/products/Win32OpenSSL.html

then set this EnvironmentVariable:

set OPENSSL_DIR=C:\Program Files\OpenSSL-Win64\

on linux :

sudo apt-get install pkg-config libssl-dev

or

sudo pacman -S openssl

or

sudo dnf install openssl-devel

or

curl -O https://www.openssl.org/source/openssl-1.1.0f.tar.gz tar xf

openssl-1.1.0f.tar.gz cd openssl-1.1.0f export CC=... ./Configure

--prefix=... linux-x86_64 -fPIC make -j$(nproc) make install

and in osx just :

xcode-select --install

brew install openssl
