Re: [xml] libxml2-2.6.18 on freebsd

[Alex Shaw <alex shaw bulletonline com>]

Thanks for you help with this, is there anyway I could apply an edit to the *.c files to push this through 
the compiler ?. I have the problem that im about 10000 miles away from the server this week, which means I 
cant do any major work. If I can get this running, I know I can rebuild it properly next week. I have mailed 
the bsd lists to find out if there is a way to resync the libaries or do anything else os related to bring 
this back online.

I tested gcc as mentioned the "hello world" app runs and compiles without any errors.

Thanks again for you help

Alex
