FYI: Build of rrdtool v1.2.13 on AIX 5.3 with xlc v8 ( Fix for jmpbuf problem !? )

[human]

Notes for rrdtool v1.2.13 build on AIX 5.3 ML6 with xlc v8

Please be aware that i am not a programmer! so the patch might break some thing.

During the make process i have got the error:

 ..... "jmpbuf" is not a member of "struct png_struct_def" 

I took a look at /opt/freeware/include/png.h and found that ifdef statement

$ /usr/bin/grep -p jmpbuf  /opt/freeware/include/png.h 

struct png_struct_def
{
#ifdef PNG_SETJMP_SUPPORTED
   jmp_buf PNG_jmpbuf;            /* used in png_error */
#endif

After patching the pngsize.c ( replacing jmp_buf with PNG_jumbuf )

$ cat rrdtool-1.2.13-AIX-jmpbuf.patch

!   if (setjmp(png_read_ptr->jmpbuf)){

      return 0;
    }

      png_destroy_read_struct(&png_read_ptr, &info_ptr, (png_infopp)NULL);
      return 0;
    }

the make process succeeded without problems. Note: This patch works also for rrdtool v1.2.24
