I run into an error when trying to configure PHP 7.2.13 with a static
openssl 1.1.1 library. The strange thing however is that using a static openssl
1.0.2 library works.
The error is as follows:
checking for OpenSSL version... >= 1.0.1
checking for CRYPTO_free in -lcrypto... yes
checking for SSL_CTX_set_ssl_version in -lssl... no
configure: error: libssl not found!
I've also tried to set:
But it did not help.
Here's my config.log: https://evermeet.cx/pub/logs/config.log
So linking against a static openssl 1.0.2 works, but against a static
openssl 1.1.1 does not work.

For some strange reason the "-lpthread" in OPENSSL_LIBS is ignored. It is necessary though, because the configure process does not add it even though it's needed for openssl.
Adding it to LIBS solved the issue.
This is the command that finally worked (my static OpenSSL 1.1.1 is in /usr/local/ssl-1.1.1):
./configure [snip] --with-openssl=/usr/local/ssl-1.1.1 [snip]
CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib LIBS="-lpthread"
OPENSSL_LIBS="-L/usr/local/ssl-1.1.1/lib -l:libssl.a -l:libcrypto.a -ldl
Info from Jan Ehrhardt:
In the next releases (7.2.25 and 7.3.12) '-pthread' in OPENSSL_LIBS will not be ignored any longer for static openssl linking.
