Adventures With Linux ™ Posted on by

I decided to try updating a crash-and-burn test system to Fedora 28 (early-beta..) as this included GCC 8 (currently 8.0.1), to see how well the Kernel (4.16-rc6) compiled.. There were a lot of warnings generated: …………………… CC [M] drivers/rtc/rtc-pcf8523.o CC drivers/usb/core/file.o CC drivers/video/hdmi.o CC [M] drivers/rtc/rtc-pcf8563.o drivers/video/hdmi.c: In function ‘hdmi_spd_infoframe_init’: drivers/video/hdmi.c:171:2: warning: ‘strncpy’ specified bound 8 equals … Continue reading →
