Dave Cottlehuber commented on COUCHDB-1181:
-------------------------------------------

JIRA cut me off mid spiel!

3. runtimes.
Need to install or bundle multiple runtimes can be reduced by compiling all pre-requisites (ICU, cURL if reqd, Spidermonkey, Erlang, wxWidgets, OpenSSL) from source using the same Visual C++ compiler. ICU is the final remaining component that was missing from this & is resolved by COUCHDB-1152.

4. small things that were tested and "work" even if not particularly legit.
a. remove erl.ini - OK so long as you set working directory to %COUCHDB%/bin or erts-5.8.2 only (i.e. one level lower not two).
b. remove werl.exe and erlsrv.exe if your users don't need access to a good console, and if you manage services directly with windows.
c. remove install.exe

5. [UNTESTED] dedupe bin and erts-*/bin
look at consolidating binaries in /bin and /erts-*/bin somehow. There's a lot of duplication.

6. [UNTESTED] prune ICU via custom DLL
ICU is a 18Mb include; a custom data file for icudt4*.dll could reduce this significantly. see:

> We should be able to get the build to 1/3 of current size. Thanks to @wohali via IRC, and @daleharvey with android build https://github.com/daleharvey/build-android-couch/blob/master/build.final#L31
> The three major contributors to the 50+MB download & 120+MB windows installed footprint are:
> 1. including all of OTP when a small portion is required to run CouchDB
> 2. including all obj, src, include, examples components of required OTP libraries
> 3. unneeded vc redist runtimes due to different build toolchains.
> Manual steps follow; I will work on extending build system later.
> 1. remove unneeded OTP libraries/apps
> - remove all but following from $COUCH_TOP/lib

> crypto-*
> debugger-*
> erlang-oauth*
