Patch to fix configure
Bug now obsolete - -r1 is patched with a fix. |
The "configure" script has implicit function declarations when trying to determine the printf long long format specifier to use. The conftest.c fails to compile under GCC 14, but "configure" does not error out. This leaves #define LLD and LLD_FORMAT to be set to "", but the package still compiles to completion. This causes MRTG to fail when reading any long long value from the network history logfiles. The conftest.c file in question is here: #include <stdio.h> int main() { long long b, a = -0x3AFAFAFAFAFAFAFALL; char buffer[1000]; sprintf (buffer, "%${format}u", a); sscanf (buffer, "%${format}u", &b); exit (b!=a); } conftest.c: In function 'main': conftest.c:8:17: error: implicit declaration of function 'exit' conftest.c:8:17: note: include '<stdlib.h>' or provide a declaration of 'exit' conftest.c:8:17: warning: incompatible implicit declaration of built-in function 'exit' conftest.c:8:17: note: include '<stdlib.h>' or provide a declaration of 'exit' I will include a patch workaround.
