Thiago, I have tried to set set OPENSSL_LIBS=-L c:\openssl-lib-1.1\lib libsslMTd.lib libcryptoMTd.lib instead of set OPENSSL_LIBS='-L c:\openssl-lib-1.1\lib libsslMTd.lib libcryptoMTd.lib’ Then I clean the build dir, configured again and build. This time the lib path is not being set at all.

Thiago, I have been cleaning and building all morning. I keep my configure lines in a file and I haven’t been doing this since 5.8. If nothing changed, the old lines should have worked. I think the problem might have something to do with the OPENSSL_LIBS env var definition. I had this OPENS

Re: [Interest] Whats the new openssl lib version to link Qt 5.10 against?

I think I read somewhere along the way that 5.10 has moved to OpenSSL 1.1. The only thing I can find right now is: https://wiki.qt.io/New_Features_in_Qt_5.10 Under "Qt Network" -> "OpenSSL 1.1 back-end". Maybe try linking with it instead of 1.0? --- Andy Maloney // https://asmaloney.com tw

Jean, Thanks for your reply. By default all the modules are selected unless you specify which ones it should skip. How can I do the opposite? Initialising only the modules I want? I’m starting with the source downloaded by Qt installer. I suppose that that tactic needs that I start with the
