Comment(by gardener_2003@…):

 Replying to [ticket:30281 carsomyr@…]:
 > GTK doesn't build on Lion because of a small problem at the linking step
 with a test program named "autotestkeywords".  Please find the build log
 and patch attached.  Does anyone know why including only headers in a file
 like autotestkeywords.cc would cause the symbol "_objc_msg_send_fixup" to
 be generated when using the 10.7 SDK as opposed to the 10.6 SDK?  In any
 case, the patch causes linkage with the requisite frameworks.


 I see this problem, may I ask how can I use this patch, I am new mac pro.
