Hello all, for those compiling for target arm-elf, I have a small bugfix at compile-time. remove: struct tm lt; in two functions. (openLog() and closeLog() or something. It are the first two functions in the file). in file: xxx/xxx5.0/gdb/rdi-share/devsw.c Otherwise I got: struct tm : size not known. struct tm is declared in the two functions but not called in any way... Regards, Jan
