Сначала всё было написано на Си, комплировалось, линковалось и работало. Добавил простейший C++ код для пробы (создание класса) и посыпались ошибки

далее

arm-elf-objdump -p crt0.o

 

crt0.o: file format elf32-littlearm

private flags = 0: [APCS-32] [FPA float format]

и в проекте

arm-elf-objdump -p main.o

 

main.o: file format elf32-littlearm

private flags = 0: [APCS-32] [FPA float format]

 

gcc-4.4.3 собран с поддержкой interwork,multilib и даже в его каталоге лежат наборы в подкаталогах thumb,interwork,fpu.

 

Подскажите, пожалуста, что я упустил.

Многие десятки килобайт однотипных warnings убраны

разобрался. взял конфу t-arm-elf с сайта gnuarm, библиотеку newlib взял старую(1.14)... похоже на то что сейчас оно тоже от фаз луны зависит, но вроде пока все без ошибок собирается

Блин, newlib- гадость редкостная. Где бы найти время ее с нуля переписать?

в каком месте гадость то? не вся же

 

если не собирается это 99.99% косяг с компиллером, даже с его сборкой
