version 5.4.2 cannot find openssl

[stumbles]

Configure fails with openssl-1.1.1a installed. So does version 5.4.0.

checking expat.h presence... yes checking for expat.h... yes checking for XML_ParserCreate in -lexpat... yes checking whether we include MD5 support for HTTP Digest Authentication.... yes checking whether we include WebDAV support.... yes checking whether we include extension methods.... yes checking whether we can find OpenSSL... configure: error: Could not find the -L/usr/lib -lssl -lcrypto libraries. You must first install openSSL.

I have tried various incantations of exporting ssl/crypto variables and sed various paths configure understands with no luck.

What’s the exact configure invocation you’re using?

Please try invoking it ./configure --with-ssl — that is, with no argument for the --with-ssl option

[stumbles]

Yes, --with-ssl.

Heres the config.log if interested. That includes adding -lssl, -lcrypto, -L/usr/lib via CFLAGS, etc.
config.log

If you installed OpenSSL from packages, did you also install the corresponding -dev package?

For example, on Ubuntu/Debian, libssl-dev

@stumbles,
libwww is using libssl 1.0.x. I don't know how many API changes exist between 1.1 and 1.0 and if libwww will work well or if you will need to patch it to use the new API.

In order to link against it, you need to update libwww's configure, which detects the ssl lib by looking for the SSL_library_init() function. However, this function has disappeared in openssl1.1. It should be OPENSSL_init_ssl().

https://wiki.openssl.org/index.php/Library_Initialization#libssl_Initialization

You can do the change in configure.ac and then call autoconf to make a new configure.

Alternatively, you can install libssl1.0 and that should work.

@jkbzh ,

Thanks. Was overlooking the function name change. That got me a lot farther, almost to the end of make. Still some ssl make failures;
