Hello, I have doubts/questions regarding atexit().
Actually eCos comes with an own atexit handler within ISO C library support. But I am not sure, if this implementation is really linked instead of standard gcc implementation. I tested with a gnu toolchain, which has no atexit implementation in his libgcc.a library. When I am generating eCos and the eCos tests, I get the linker error messages: ... /lib\extras.o: In function `__static_initialization_and_destruction_0': ... /ecos/packages/io/fileio/current/src/misc.cxx:103: undefined reference to `__aeabi_atexit' My linker options already includes "-nostdlib", bit this seems not to be sufficient for atexit issue. When I add compiler option "-fno-use-cxa-atexit", everything will be generated. Who could explain, how this works in detail. Seems there are different definitions of atexit in libraries and in eCos. How I can ensure, that the right one is used. A further question: the compiler or linker is replacing somehow the atexit calls with calls to __aeabi_atexit. How this is working.
