In my project, I want to get different environment value according to different OS, just like get A from Windows and get B from Linux, I try to use filter function like the code shown below:
filter {"system:windows"}
local value = os.getenv("A")
filter {"system:linux"}
local value = os.getenv("B")
or use configuration like that:
configuration {"windows"}
local value = os.getenv("A")
configuration {"linux"}
local value = os.getenv("B")
When I run the premake5.lua, it will return an error: attempt to concatenate a nil value.
Is there anything I misunderstand? How can I implement it correctly?
Another option:
if os.is("windows") then
...
else if os.is("macosx") then
...
else if os.is("linux") then
...
end
