Andrew Stitcher commented on PROTON-1381:
-----------------------------------------
I've tried to apply this patch to master and failed.
{{DH_set0_pqg()}} is not declared:
{noformat}
../proton-c/src/ssl/openssl.c: In function ‘get_dh2048’:
../proton-c/src/ssl/openssl.c:399:11: error: implicit declaration of function
‘DH_set0_pqg’ [-Wimplicit-function-declaration]
|| !DH_set0_pqg(dh, dhp_bn, NULL, dhg_bn)) {
^~~~~~~~~~~
{noformat}
My development box has openssl 1.0.2j (Fedora 25)
In fact the openssl manpage at
https://www.openssl.org/docs/man1.1.0/crypto/DH_get0_pqg.html says that this
was introduced in openssl 1.1.0.
So I think you must have made some mistake when you verified with earlier
versions of openssl.
I'd very much like to get this issue fixed, but I can't commit a change that
won't work with current versions of openssl too.
