Cannot build OpenSSL 1.1.1pre4 on Nginx mainline 1.13.12?

[Graymanflo@…]

Good evening!

I am trying to compile OpenSSL 1.1.1pre4 with Nginx 1.13.12, for this I had to disable -Werror in auto/cc/gcc to omit a missing initializer warning which was treated as an error in OpenSSL, I believe this causes the build to fail since compiling with OpenSSL 1.0.2n works fine ​https://github.com/openssl/openssl/issues/5955.

Here is the Nginx build log for OpenSSL 1.1.1pre4: ​https://pastebin.com/ir2DkBTm. What could be wrong or is there a specific way I have to compile Nginx to use OpenSSL 1.1.1?

From the symptoms described, it looks like the CFLAGS value as constructed by nginx ./configure and set in nginx's Makefile is somehow propagated to OpenSSL config and building, which shouldn't normally happen. Something like this can happen if somehow export CFLAGS or ​.EXPORT_ALL_VARIABLES was added to make rules.

In Debian packages, using DPKG_EXPORT_BUILDFLAGS=1 seems to have identical effect, and will be enough to screw things up if nginx is configured to build something with --with-openssl=... or similar options. If there is DPKG_EXPORT_BUILDFLAGS=1 in your debian/rules file, try commenting it out.

Thanks, I tried commenting it out and even setting its value to 0 but the new rule did not do the trick here.

Could there be any other obstacle causing the error 2 as seen in the pastebin link above?

Quick update to this, adding --with-pcre=pcre2-10.31 is the cause of the build failing.

Building with PCRE2 is not something nginx supports. You have to use PCRE, not PCRE2.
