Getting Not Authorized error from twitcurl timelineUserGet method - c++

Question

I'm currently playing with C++ on Linux and Twitter using twitcurl. I've built twitcurl, and it seems to work generally, I've been able to tweet from a slightly customised version of the twitterClient sample from their project. However, I've been struggling to read user's timelines.
Now, I know general authentication is working as I manage to tweet as the correct user first.
However, when I try to read user timelines using the below code:
/* Get user timeline */
replyMsg = "";
printf( "\nGetting user timeline\n" );
if( twitterObj.timelineUserGet( true, false, 5 ) )
{
twitterObj.getLastWebResponse( replyMsg );
printf( "\ntwitterClient:: twitCurl::timelineUserGet web response:\n%s\n", replyMsg.c_str() );
}
else
{
twitterObj.getLastCurlError( replyMsg );
printf( "\ntwitterClient:: twitCurl::timelineUserGet error:\n%s\n", replyMsg.c_str() );
}
I get the following error:
twitterClient:: twitCurl::timelineUserGet web response:
<?xml version="1.0" encoding="UTF-8"?><hash><request>/1/statuses/user_timeline.xml? count=5?trim_user=1</request><error>Not authorized</error></hash>
I'm unsure whether this is related to the invalid url twitcurl generates with multiple ? symbols which might conflict with authentication.

The following post helped me to solve the same problem
What steps will reproduce the problem?
Sending certain characters to twitter API (Any character that has to be percent encoding, except the blank space?).
What is the expected output? What do you see instead?
I'd expect
twitter's server to accept my oauth signature but it hits me in the
face instead.
What version of the product are you using? On what operating system?
r88, this problem applies to both linux and wii (through devkitpro)
Please provide any additional information below.
The problem can be fixed by removing the urlencode() calls within buildOAuthRawDataKeyValPairs() in oauth.cpp.
That is according to how twitter says we have to do it. I don't know (did not check) if that's how the oauth spec says it should be done but it is clearly how it works with twitter.
Did you write oauthlib.cpp?
