I just picked up an old project and I'm not sure what the following error could mean.
g++ -o BufferedReader.o -c -g -Wall -std=c++0x -I/usr/include/xmms2 -Ijsoncpp/include/json/ -fopenmp -I/usr/include/ImageMagick -I/usr/include/xmms2 -I/usr/include/libvisual-0.4 -D_GNU_SOURCE=1 -D_REENTRANT -I/usr/include/SDL -DQT_CORE_LIB -DQT_GUI_LIB -DQT_SCRIPT_LIB -DQT_SHARED -I/usr/include/QtCore -I/usr/include/QtGui -I/usr/include/QtScript BufferedReader.cpp

At line 24 of BufferedReader.cpp is #include <string.h>. I've tried it with just <string> but get the same thing. Any clue?
Here's the snippet of code from string.h
/* Tell the caller that we provide correct C++ prototypes. */
#if defined __cplusplus && __GNUC_PREREQ (4, 4) //line 36
# define __CORRECT_ISO_CPP_STRING_H_PROTO
#endif
Does that mean __GNUC_PREREQ isn't defined?
Edit:
Changing -Ijsoncpp/include/json/ to Ijsoncpp/include stopped the errors. I noticed I was including <json/json.h>.
I'm about to switch to JsonGlib though, which is the reason I pulled the project up again. So it's all good. :)
