Undefined reference error (yagarto/msys/gcc)

#1856750
Hi! I have been trying to compile a file, but I keep getting error messages similar to the one below, complaining about undefined references to things like _read, _close, _lseek, etc... How do I fix this? C:\msys\1.0\home\yagarto\newlib-build\arm-none-eabi\newlib\libc\reent/.. /../../../../newlib-1.18.0//newlib/libc/reent/lseekr.c:58: undefined reference to '_lseek' superbird70 wrote: >...complaining about undefined > references to things like _read, _close, _lseek, etc... FAQ. Read the newlib's manual (ftp://sources.redhat.com/pub/newlib/libc.pdf), section System Calls, check source-files called syscalls.c (or similar) for examples from Yagarto or other sources. Did you already solved it? I think those functions are not provided so what you have to do is to implement it. I had the same errors. I will attach my file which you can use. Hi, I trid to use you file but I get some errors. Every from you as avoid warning marked line I get error messages. For example: Assiment to itself file = file I use C not C++. Could this be a reason and how can I fix this in C? Reply |
