Пытаюсь использовать функцию из libxxx.so, взятой из Windriver arm hf 2.6.32. Эмулирую на qemu Debian wheezy hf 3.2.0. Скомпилив простейший бинарник hello, где вызываю dlopen на libxxx.so, получаю ошибку «cannot open shared object file: No such file or dirrectory”. Хотя:
strace:
open("/usr/src/hello/libxxx.so", O_RDONLY) = 3
