The ideas from #8 and #9 can also help to reduce binary size.

Ideas:

• Use -ffunction-sections -fdata-sections in CFLAGS, and -Wl,--gc-sections in LDFLAGS to allow stronger dead code elimination across language boundaries
  • Proposal: Improve dead code ilimination when using CGO golang/go#38135
  • This causes each function to have segment alignment. If a large proportion of the Miqt C ABI functions are used, all the extra padding in the binary could create a net negative effect. Only section alignment, not segment alignment.
• Attempt to build with gccgo
  • Some reports online that this can produce a significant size reduction (although with adding external dynamic dependencies)
• Refactor marshaling code to call helper functions instead of inlining it in every function wrapper
• Ability to disable unwanted Qt classes at compile time?
  • Maybe with a build tag
  • Similar idea to qtminimal
• Ability to disable subclassing support for unneeded classes?
  • The comment in Support subclassing #42 (comment) shows that subclassing support did increase the binary size noticably
