Compile Error

[Midimaster]

I just installed the BlitzMax NG 64bit on Windows 10 to test the BaH-libcurl. When I run expample #8 it works as expected. I can read the html-page in the OUTPUT-Window, but in the end I have this box on the screen:


What does this mean? What do I do wrong?

The Example8-Code:

Code: BlitzMax

1. SuperStrict
2. ' Connect to a website via HTTPS, using a certificate bundle.
3. '
4. Framework BaH.libcurl
5. Import BRL.StandardIO
6. Import BRL.FileSystem
7.  
8. Local curl:TCurlEasy = TCurlEasy.Create()
9.  
10. curl.setWriteString()
11. curl.setOptInt(CURLOPT_VERBOSE, 1)
12. curl.setOptInt(CURLOPT_FOLLOWLOCATION, 1)
13.  
14. curl.setOptString(CURLOPT_CAINFO, "cacert.pem") ' the cert bundle
15. curl.setOptString(CURLOPT_URL, "https://www.schuh-heyder.de")
16.  
17. Local res:Int = curl.perform()
18.  
19. If res Then
20.         Print CurlError(res)
21.         End
22. End If
23.  
24. curl.cleanup()
25. Print curl.toString()
26.  

The Output-Window (removed the html-page content):

The error message possibly comes from libcurl (some output from there) - as it seems to compile fine and the error happens on "execution" ?

so maybe the "error" is something "libcurl" spits out ... but "maxide" reads from the "stderr" pipe (the text stream for error messages - compared to stdout, for normal "output").


I assume doing the same without the "bundle" stuff (just reading eg the https://www.syntaxbomb.com website) works without the error?

curl.setOptInt(CURLOPT_VERBOSE, 1)

-> remove that and the compile error message is gone. So it has to do with a message curl prints out.

You could also keep it in - and do your own debug-func (replaces the original one - which outputs your stuff I think).

Code: BlitzMax

1. SuperStrict
2.  
3. ' Connect to a website via HTTPS, using a certificate bundle.
4. '
5. '
6.  
7. Framework BaH.libcurl
8. Import BRL.StandardIO
9. Import BRL.FileSystem
10.  
11. Local curl:TCurlEasy = TCurlEasy.Create()
12.  
13. curl.setWriteString()
14. curl.setOptInt(CURLOPT_VERBOSE, 1)
15. curl.setOptInt(CURLOPT_FOLLOWLOCATION, 1)
16. 'register your own debug callback - to disable the message you encountered
17. curl.setDebugCallback(myCurlDebugFunc)
18.  
19. curl.setOptString(CURLOPT_CAINFO, "../certificates/cacert.pem") ' the cert bundle
20.  
21. curl.setOptString(CURLOPT_URL, "https://www.google.co.uk")
22.  
23. Local res:Int = curl.perform()
24.  
25. If res Then
26.         Print "error: "
27.         Print CurlError(res)
28.         End
29. End If
30.  
31. curl.cleanup()
32.  
33. 'Print curl.toString()
34.  
35.  
36.  
37. Function myCurlDebugFunc:Int(data:Object, msgType:Int, message:String)
38.         Select msgType
39.                 'Case CURLINFO_TEXT       Print "msgType: TEXT"
40.                 'Case CURLINFO_HEADER_IN  Print "msgType: HEADER_IN"
41.                 'Case CURLINFO_HEADER_OUT Print "msgType: HEADER_OUT"
42.                
43.                 'curl read some data from remote (eg webpage content
44.                 'Case CURLINFO_DATA_IN    Print "msgType: DATA_IN"; Print "data: " +message
45.         End Select
46.        
47.         'must return 0
48.         Return 0
49. End Function
50.
