Issues while compiling C files in QtCreator

I'm learning c/c++ and wanted to do some work with QT Creator. I am using a base64 class that just refuses to compile and any help wou开发者_C百科ld be greatly appreciated.

The error lines I get is

/QTDev/PolicyFrameworkDesktop-build-desktop/../PolicyFrameworkDesktop/libhaggle/base64.h:59: error: expected ';', ',' or ')' before 'in'

/QTDev/PolicyFrameworkDesktop-build-desktop/../PolicyFrameworkDesktop/libhaggle/base64.h:66: error: expected ';', ',' or ')' before 'in'

/QTDev/PolicyFrameworkDesktop-build-desktop/../PolicyFrameworkDesktop/libhaggle/base64.c:68: error: expected ';', ',' or ')' before 'in'

/QTDev/PolicyFrameworkDesktop-build-desktop/../PolicyFrameworkDesktop/libhaggle/base64.c:: error: At top level:

/QTDev/PolicyFrameworkDesktop-build-desktop/../PolicyFrameworkDesktop/libhaggle/base64.c:320: error: expected ';', ',' or ')' before '*' token

/QTDev/PolicyFrameworkDesktop-build-desktop/../PolicyFrameworkDesktop/libhaggle/base64.c:373: error: expected ';', ',' or ')' before 'in'
/QTDev/PolicyFrameworkDesktop-build-desktop/../PolicyFrameworkDesktop/libhaggle/base64.c:456: error: expected ';', ',' or ')' before 'in'

Since I can only add one link at a time, the base64.h file is attached. I've been trying to figure out the problem all day.

Thanks

The header uses the C99 specific keyword restrict that your compiler apparently does not handle :

extern void base64_encode (const char *restrict in, size_t inlen,
                           char *restrict out, size_t outlen);

However, the file also contains a :

#ifdef __cplusplus
// In case we do not have gnu extensions when including from C++
#define restrict
#endif

Which means that even a C++ compiler which doesn't handle the restrict keyword should not break on this code. You should check that you are actually compiling C++ (file extension might be of importance : are you including this file from a .cpp or a .c ?).
