Problem with WiFi connection failure due to the OpenSSL version of the wireless tool transplant

On hand, a device using Rtl8188eus, before debugging WiFi function is OK, yesterday from the AP switch to station mode, found that the router is not connected. Prompt for the following error:

Wpa_supplicant:can ' t load library ' libssl.so.0.9.8 '

Then find the previously ported openssl-0.9.8e library, download to the device Lib directory, after the establishment of soft links, rerun. Still not connected to the network, view the WiFi-driven debugging information, as follows:

When you run the Wpa_supplicant service manually, the error is as follows:

Failed to connect to Non-global Ctrl_ifname:wlan0 Error:connection refused

Back to the previous compilation of the porting Rtl8188eus driver and Wpa_supplicant tool directory, only to discover the problem, I used the wpa_supplicant is 2.5 version, it corresponds to the OpenSSL version number for Openssl-0.9.8za and Openssl-0.9.8zf

The openssl-0.9.8e version is downloaded from the previous step.

Swap the library with Openssl-0.9.8za to connect the router again to solve the problem.
