Hm.. I did not think about this.. I use GNU ld with "-L <smth> -Wl,--gc-sections -nostartfiles -Ttarget.ld -nostdlib" flags.. Simple "hello, world" and some more complex programms work's properly.. How to check, which way the program was linked?..



The command "XXX-objdump -h file.elf" will show how the program was
linked.


(19:39:25 snoopy@starlake:project)$ v850-elf-objdump -h binary/tracker.elf

binary/tracker.elf: file format elf32-v850

It seems, that program linked correctly..

PS: When I turn on full kernel debug, that my above programm work's fine.. but when I try to execute more complex multithreaded program, this programm failed while system initialization with "ASSERT FAIL: mutex.cxx cyg_bool Cyg_Mutex::lock()".. :(



This would be a separate problem. Have you run the standard tests to see how they perform on your platform?


There are all kernel tests, that I have:

bin_sem0: are not compiled
bin_sem1: OK
bin_sem2: are not compiled
bin_sem3: OK
clock0: are not compiled
clock1: OK
clockcnv: OK
clocktruth: are not compiled
cnt_sem0: are not compiled
cnt_sem1: OK
dhrystone: NOTAPPLICABLE
except1: FAIL
flag0: are not compiled
flag1: OK
fptest: does not work, because problems with threads

Tests, that "are not compiled", failed while compilation with "undefined reference to `___gxx_personality_sj0'" error..
