Subject: [PATCH] Do not check for ERR_remove_thread_state() (do not link ssl
|
|
into every library)
|
|
|
|
This reverts commit c4e9d9bd662de7f575f2172c160795d452ebe709
|
|
("sample/https-client: check for ERR_remove_thread_state() existence").
|
|
|
|
Calling AC_SEARCH_LIBS() modifies LIBS - -lcrypto incorrectly
|
|
ends up in LIBS, and thus linked to by libevent_core.so.
|
|
|
|
Checking for ERR_remove_thread_state should no longer be needed
|
|
because it was introduced in openssl 1.0.0, and the previous line
|
|
0.9.8 had support discontinued at the end of 2015.
|
|
|
|
Fixes: #473
