 8) 2017/07/27 - ak19 ([email protected]) - still using wget version 1.15, but now compiling wget up with OpenSSL support. Wget needs SSL support in order for it to access pages over HTTPS. In future, the web will be using https.
 
-We're now compiling up OpenSSL during the configuration phase since wget needs it to exist during its configure phase. We're building OpenSSL statically, by setting the no-shared flag. The built OpenSSL gets put into gs2build/linux|darwin/openssl, containing lib, include and bin subfolders. When configuring wget, we build wget against our OpenSSl, and make and make install proceed as normal. Refer to gs2build/build-src/packages configure.

+We're now compiling up OpenSSL during the configuration phase since wget needs it to exist during its configure phase. We're building OpenSSL statically, by setting the no-shared flag. Since OpenSSL is being statically built, we don't need to ship its lib, bin and include folders with GS, since wget will be compiled and linked against our static openSSL, producing a wget binary independent of OpenSSL. The built OpenSSL now just gets put into gs2build/build-src/packages/openssl too, along with other openSSL subfolders generated when compiling openSSL.

 We weren't compiling up wget statically before either, so we're still not doing so. But if that will be necessary in future, see the section on COMPILING WGET UP STATICALLY further below.

 The wget 1.11.4 we have, compiled without SSL does not work on https pages.
-Neither does the wget from http://nebm.ist.utl.pt/~glopes/wget/, even after including the --no-check-certificate flag in the wget command. So we'll need to upgrade the wget binary on Windows to a later version too.

 - Grabbed wget-1.17.1.tar.gz from https://ftp.gnu.org/gnu/wget/
-- Made the modifications in steps 5 and 6 above and re-tarred as wget-1.17.1-gs.tar.gz, with corresponding changes in build-src/packages' configure, Makefile.in and Makefile
+- Made the modifications in steps 5 and 6 above
+- To be compatible with the version of pod2man doc generation tool installed on LSB release-kit machines, can't pass the new --utf8 flag to it. Changed doc/Makefile.in and doc/Makefile.am from:
+  $(POD2MAN) --center="GNU Wget" --release="GNU Wget @VERSION@" --utf8 $? > $@

 - The configure step has now changed for wget v 1.17.1. Refer to build-src/packages/configure

 * --with-libssl-prefix to $bindir/openssl, so the wget build process can find openssl's include and lib folders. (Whereas the --with-ssl indicates what type of ssl we're using, which is openssl in our case.)
 * configuring had initially failed, reporting that OPENSSL_CFLAGS and OPENSSL_LIBS need to be set if not wanting to use whatever pkg-config may find. To set LIBS variables, use one of these forms: LIBS="-L/path/to/lib" or LIBS="/path/to/lib/lib.a" or LIBS="-lssl". To combine all three, separate with spaces.

+SHIFTING TO WGET 1.19
+Wget 1.19 doesn't yet compile on Mac, but it works on Linux.
+Shifting to wget-1.19 requires only steps 5 and 6 to be applied to get wget-1.19-gs. This new version of wget takes care of the pod2man issue on our LSB release-kit environment without requiring the additional edits seen in (9) above.

 TO DO:
 + If I delete the gs2build/bin/linux/openssl folder, the built wget still works fine without it. Dr Bainbridge confirmed that this is because, wget is built against OpenSSL's static libraries and therefore no longer needs the OpenSSL stuff we build and have been putting into gs2build/bin/linux/openssl. So we no longer need to put the built OpenSSL there.
