ERROR: MethodError: no method matching curl_debug_cb(::Ptr{Nothing}, ::Int32, ::Ptr{Nothing}, ::UInt64, ::Ptr{Nothing})

[kafisatz]

Hi
and thanks again for your package.

when using verbose = true, I get the error below

curl = CurlHTTP.CurlEasy(url=url,method=CurlHTTP.POST,verbose=true)

In my case the second last argument of curl_debug_cb, is a UInt64, but the signature expects 32.
Any idea how to fix this?

Let me look into this.

Ok, I think the bug is that I used Culong instead of Csize_t in the definition for curl_debug_cb, which works correctly on 64 bit machines, but will fail on 32 or 16 bit. I'll fix it asap.

[kafisatz]

strangely my machine is 64 bit (for all I know).
i think your fix should work for me though.
Although I wonder why you need a type declaration on that variable at all...

[bluesmoon]

type declaration is required because it is called from the libcurl C library.

I don't understand why it would work on some machines but not others, but it seems that Csize_t is the same as UInt64 on 64 bit machines, while it is UInt32 on 32 bit machines.
