Size executable of hello app

[renlite]

Hi,
the "hello.exe" from "Getting started" has a size of 16 MB. This seems to be a big size for a minimum app.
Is this common or are there compiler/build options to reduce the footprint?

It depends which platform you are building for. Basic app is around 8MB due to the go runtime and some embedded resources. It will be larger if you are packaging for multiple OS architectures.

For a more detailed response please complete the bug template with os/version and commands used

use command go build -ldflags "-w -s -H=windowsgui" - which reduce size to aprox. 8(7.8) MB (ordinary -H=windowsgui only few kilobite, but it remove console),
and if you do not need fast start you can use upx --ultra-brute ..., it together comprest to 2.8 MB ............., but I do not recomend use upx on android apk......... .

Please use the fyne tools (fyne package) and report back.
We cannot help what the go build phase outputs but there are various flags and improvements applied through the fyne command.

(I would always recommend using the fyne package command as without it your windows executable will not have appropriate icon embedded etc)

it is similar #1097

使用命令go build -ldflags "-w -s -H=windowsgui"- 将大小减少到大约。8(7.8) MB（一般-H=windowsgui只有几千字节，但它去掉了控制台），
如果你不需要快速启动，你可以使用upx --ultra-brute ...，它加起来压缩到 2.8 MB ........，但是我不建议在 android apk 上使用 upx .......

I agree with you :)

go build -ldflags "-w -s -H=windowsgui" helped to reduce the size to 8 MB.
Thanks

Just FYI for others landing here, those parameters are set if you use fyne package instead of the go build.
