Hi, I've just installed xulrunner-devel from yum: # yum install xulrunner-devel The xulrunner-sdk-1.9 was installed, but there are following header files cannot be found in xulrunner-sdk-1.9/sdk/include: mozilla-config.h mozilla-config32.h prtypes.h The include/xulrunner-sdk-1.9 does constain mozilla-config.h and mozilla-config32.h, I fixed it by linking those two files in xulrunner-sdk-1.9/sdk/includ. The prtypes.h can only be found in following places: /usr/include/nspr4/prtypes.h /usr/include/xulrunner-sdk-1.9/system_wrappers/prtypes.h /usr/include/xulrunner-sdk-1.9/stable/prtypes.h I've tried to link either of the prtypes.h in xulrunner-sdk-1.9/sdk/include, but none of them works. At final, I failed to build VLC mozilla plugin linking to xulrunner-sdk-1.9/sdk. Am I missing something here, is there a correct xulrunner-devel sdk package I can download from? Or is it a bug in xulrunner-devel sdk package? Please advise how can I fix this problem? Thank you. Kind regards, Jim
