windows openssl compilation error

[triplewz]

你好，请问这个能在windows下编译吗，我编译的时候出现这个问题是怎么回事呢？

error: failed to run custom build command for `openssl-sys v0.9.60`

It can be compiled on Windows, but you need to install openssl library first.

The easiest way is to install Strawberry Perl, which will include all the requried openssl dependences.

Some of features need openssl source code for cross compilation targeting other instruction set.

But for x86/x64, there is actually an easier way to install precompiled openssl from https://slproweb.com/products/Win32OpenSSL.html

1. Please use the default install path.
2. After installation, set system environment variable OPENSSL_DIR=C:\Program Files\OpenSSL-Win64

Then cargo build should work.

I have installed OPENSSL, and set system environment variable. But it did't work.

Strange. Use openssl on Windows is complex :-)

Could you try to remove OPENSSL_INCLUDE_DIR and OPENSSL_LIB_DIR?

I only set OPENSSL_DIR=C:\Program Files\OpenSSL-Win64 on my computer.

If it is still not working , just try installing the Strawberry Perl.

I reinstalled OPENSSL, and built it successfully. Thanks!

Cool. Good to know this :-)
