There is possibly a way to do this by parsing strings in the binary. Because when -cover is enabled, go will insert instrumentation statements into the source code, thus the resulting binary would contain these info.

Akash Kumar a következőt írta (2024. május 13., hétfő, 18:42:30 UTC+2):
I am writing an external go program that will take the path to another go binary as argument, and checks if the binary was built with cover flag.
`debug.ReadBuildInfo()` is meant for getting build info embedded in the running binary as > ReadBuildInfo returns the build information embedded in the running binary

try debug.ReadBuildInfo(), then iterate the pair in the buildinfo.Settings

Is there a way in go to find whether a go binary is built with -cover flag ?
