So I want to compile USB loader GX but experienced a strange error. Yesterday I could compile any revision of USB loader GX i wanted without any errors or warnings. Today I get following lines while linking the boot.elf file Note: I did NOT modify anything! It just happend. CODElinking ... boot.elf networkops.o: In function `CheckUpdate': c:/SlikSvn/bin/usbloader-gui/source/network/networkops.cpp:377: undefined reference to `GetRev' c:/SlikSvn/bin/usbloader-gui/source/network/networkops.cpp:377: undefined reference to `GetRev' PromptWindows.o: In function `WindowCredits()': PromptWindows.cpp.text._Z13WindowCreditsv+0x230): undefined reference to `GetRev' http.o: In function `downloadfile': c:/SlikSvn/bin/usbloader-gui/source/network/http.c:201: undefined reference to `GetRev' collect2: ld returned 1 exit status make: *** [/c/SlikSvn/bin/usbloader-gui/boot.elf] Error 1 "make": *** [build] Error 2 > Process Exit Code: 2 I though my portlibs or libogc are corrupted somewhere, so I re-nstalled all portlibs and libogc and even tried the recommended libogc from the google code page, but I'm still getting the error.
