Ports depending on SDL3 can't be installed on < macOS 11

[mrkapqa]

Hello ,

encurring this error on Catalina 10.15 when upgrading macports

--->  Building SDL3                                      
Error: Failed to build SDL3: command execution failed   

thank you very much.

SDL3 builds on macOS 11 or later. When you install it on 10.15, there should be a message telling you that it is known to fail. Are you deliberately installing SDL3, or is it a dependency of one of your other ports?

[mrkapqa]

it is a dependency i presume since never installed it consciously; it is listed as

SDL3                           @3.2.18         devel/SDL3
SDL3_ttf                       @3.2.2          devel/SDL3_ttf

maybe due to "gtk3-devel" which is only can remember that i install with "devel" on mac probaly thanks

The ports that depend on SDL3 by default appear to be FreeRDP and swi-prolog-devel.

In 6894405ef26656c0a3839aeb0e05becf487c12df/macports-ports (master):

FreeRDP: default to +sdl2 on older OS versions

See: #72761

Replying to jmroot:

SDL3 builds and works even on 10.5, if you use X11 backend. It is the port which is broken.

have disabled port "freerdp" but sdl3 still fail build when "port upgrade"?

[mrkapqa]

dont know if this is the proper place to post here

however, the sdl3 seem to wanna persist on the computer.

it is deactivated, but still included in "port upgrade"?

Evidently, SDL3 is in the dependency chain of a port you have installed. This command might show you which one(s):

port installed depends:':SDL3($|\s)'
