In my opinion, true and false look nicer. https://docs.racket-lang.org/reference/booleans.html?q=true#%28part._.Boolean_.Aliases%29

Hi! I’am having problems launching DrRacket. It opens a console window saying: ffi-lib: couldn’t open “libintl–9.dll” (The specified module could not be found.; errid=126). Do you know why? Thanks.

I can’t help, but it would be nice to have more information. I presume you are using Windows? Which Windows? Which version of Racket do you have, and which variant. Etc.

I can’t help much either (I don’t have Windows), but quite likely either you are missing a dll, or it is already there but can’t be found (i.e., the path to the dll is not reachable from the %PATH% environment variable).

Im using windows 10 and the latest version of Racket 7.9

Anyway, i found the problem. I have to edit the config.rkt file, and i think i did something wrong

I want to use the vulkan API

I need to put the path where vulkan–1.dll is found

I inserted inside the hash the line (lib-search-dirs . (“myPath”))

And then the problem i said ocurrs

If i eliminate that line all come back to normal

@hectometrocuadrado, if you’re loading vulkan–1.dll, then perhaps vulkan–1.dll needs the code in libintl–9.dll, so that would explain the message. You can try getting a hold of libintl–9.dll and then placing it in the same directory as vulkan–1.dll. (By the way, I don’t know anything about Vulkan or even DrRacket.)

Ok, ill try it. Thanks.
