由于未声明SSL_OP_MSIE_SSLV2_RSA_PADDING，因此无法通过RBEnv安装Ruby 1.9.3-p194

Question

I try to install Ruby on a clean server.

Server was a Debian 6.0.9 which I upgraded to Debian 7.5

I've installed RBEnv with build-support via apt-get install.

When I try to install Ruby 1.9.3-p194 (summed in the list via ruby-build --definitions), I got an error the installation failed.

When I check the error in the log file, I got next error:

I've installed/updated the openSSL version (OpenSSL 1.0.1e 11 Feb 2013) and installed libssl-dev, but the error stays.

Anyone an idea what I'm missing to have SSL_OP_MSIE_SSLV2_RSA_PADDING declared? Is this an error in the Ruby-installation, or do I have a setup issue somewhere else?

All advice is welcome :)

(I already spend some time googling this, search on lot of sites, I guess I'm looking for the wrong solutions..)

-- Edit: I found Ruby 2.1 fails to install due to OpenSSL error where it said the macro is removed in latest OPEN_SSL, does this mean I cannot use Ruby 1.9.x anymore? When I list ruby versions available via rbenv, no stable ruby 2 is listed + I prefer to keep using Ruby 1.9. Should I downgrade open_ssl (not wise idea) or ?

Answer 1

It looks like the define was dropped sometime after 1.0.1e-2+deb7u6, certainly is not present in 1.0.1e-2+deb7u10.

I worked around this by adding

#define SSL_OP_MSIE_SSLV2_RSA_PADDING           0x00000040L /* no effect since 0.9.7h and 0.9.8b */ 

back to /usr/include/openssl/ssl.h. (Picked from 1.0.1e-2+deb7u6)

Do at your own risk, I have not investigated what will happen if that value is passed.
