I quickly ran ./configure before work and configure worked OK. But tonight, run make, my linker bombed out with: /usr/lib/gcc/i486-slackware-linux/4.8.2/../../../../i486-slackware-linux/bin/ld: cannot find -libmbedtls /usr/lib/gcc/i486-slackware-linux/4.8.2/../../../../i486-slackware-linux/bin/ld: cannot find -libmbedx509 /usr/lib/gcc/i486-slackware-linux/4.8.2/../../../../i486-slackware-linux/bin/ld: cannot find -libmbedcrypto Strange, as ldconfig -v reveals: /usr/local/lib: libmbedcrypto.so.0 -> libmbedcrypto.so.2.3.0 libmbedtls.so.10 -> libmbedtls.so.2.3.0 libmbedx509.so.0 -> libmbedx509.so.2.3.0 Anyway, an hour of investing, it turns out the linker flags are incorrect - changing in configure fixed it up: if test "x$ssl_ok" = "xyes"; then LIBSSL_LIBS="-libmbedtls -libmbedx509 -libmbedcrypto" Should be -lmbedtls, -lmbedx509 and -lmbedcrypto All really does build fine now :) mbedtls seems to work well - seems a tad quicker too.

I was able to reproduce the problem by uninstalling mbed tls and then pointing to it during configuration with CPPFLAGS to the include dir and LDFLAGS to the lib dir. Making the attached changes makes it succeed, although I've only gotten just that far at the moment and haven't looked into whether it's an error on their part or what...

I don't remember ever seeing quite that sort of set of warnings out of autoconf before.

All right, then. *commits* If you need mbed TLS 2.x: https://tls.mbed.org/download If you watch the MSGs, you'll see I've turned off the certificate chain printing and instead show a more concise summary at shutdown of which root certificates were used to verify communication with which servers. And at startup it'll tell you how many such certificates you are trusting. By default, I had 174, but I've trimmed them down on this computer to...twenty at the moment because I never need the ones from certificate authorities in China, Turkey, Hungary, etc.

Fixed. (With one open issue which has been an open issue for a long time.) Sebastian
