Currently ƛ unpacks 109 MB .tar.gz to /tmp folder which takes ~1-2 seconds on cold start.
Would be nice to create a single compressed executable to save unpack time and increase portability. I tried using Ermine packager and it works!! But unfortunately this is commercial software. Similar open-source analogue Statifier produces broken binaries.
Maybe someone has another idea how to create a single executable from a folder full of shared objects.
I am not a Linux or C++ expert, so for sure I missed some easy "hacks" to reduce size of compiled LibreOffice.
Mostly I just excluded from compilation as much unrelated stuff as possible. And stripped symbols from shared objects.
Here is the list of: available RPM packages and libraries available in AWS Lambda Environment, which can be helpful.
