I try to install the most recent nvidia-GPU driver for FreeBSD, which is 319.23.
I face a strange bug, which reports while compiling:

nvidia_sysctl.c nvidia_sysctl.c:174:1: error: control reaches end of
non-void function [-Werror,-Wreturn-type] } ^ 1 error generated. ***

Interestingly, the line 174 of file nvidia_sysctl.c is a function
called
int nvidia_sysctl_bus_type(SYSCTL_HANDLER_ARGS)
{
struct nvidia_softc *sc = arg1;
char *bus_type;
if (nvidia_pci_find_capability(sc->dev, PCIR_CAP_ID_EXP) != 0)
bus_type = "PCIe";
else
bus_type = "PCI";
}
which is supposed to be patched by the Makefile of the port - but for
some reasons, there is the "return 0;" gone as well as the patched
line, which can be found in nvidia_sysctl.c.bak and states:
int nvidia_sysctl_bus_type(SYSCTL_HANDLER_ARGS)
{
struct nvidia_softc *sc = arg1;
char *bus_type;
if (nvidia_pci_find_capability(sc->dev, PCIR_CAP_ID_EXP) != 0)
bus_type = "PCIe";
else
bus_type = "PCI";
return SYSCTL_OUT(req, bus_type, strlen(bus_type) + 1);
}
Somehow, the complete return SYSCTL_OUT() gets deleted.
