[C,C++][nmap][arm] Проблемы конечной линковки с libc и прочим
Добрый день! Удалось почти победить кросс-сборку nmap под arm тулчейном gcc+uClibc. Одако на самом последнем этапе - линковке возникли проблемы. nmap загружаю из svn.
Вот строка конфигурации:
./configure --host=arm-android-linux-uclibcgnueabi CC="arm-android-linux-uclibcgnueabi-gcc" \
CXX="arm-android-linux-uclibcgnueabi-g++" STRIP="arm-android-linux-uclibcgnueabi-strip" \
AR="arm-android-linux-uclibcgnueabi-ar" AS="arm-android-linux-uclibcgnueabi-as" \
CPP="arm-android-linux-uclibcgnueabi-cpp" LD="arm-android-linux-uclibcgnueabi-ld" \
RANLIB="arm-android-linux-uclibcgnueabi-ranlib" OBJDUMP="arm-android-linux-uclibcgnueabi-objdump" \
NM="arm-android-linux-uclibcgnueabi-nm" CROSS_COMPILE="arm-android-linux-uclibcgnueabi-" \
CFLAGS=" -nodefaultlibs -nostdlib -fPIC -static $_XXFLAGS -DHAVE_GETADDRINFO -DHAVE_USLEEP -DHAVE_GETTIMEOFDAY \
-DHAVE_SNPRINTF -DHAVE_VSNPRINTF -DHAVE_STRERROR -Dsys_nerr=_sys_nerr -Dsys_errlist=_sys_errlist" \
CXXFLAGS=" -c -nodefaultlibs -nostdlib -fPIC -static $_XXFLAGS -DHAVE_GETADDRINFO -DHAVE_USLEEP -DHAVE_GETTIMEOFDAY \
-DHAVE_SNPRINTF -DHAVE_VSNPRINTF -DHAVE_STRERROR -Dsys_nerr=_sys_nerr -Dsys_errlist=_sys_errlist" \
CPPFLAGS=" -I$HOME/build/cross/sys-root/usr/include" \
LDFLAGS=" -nodefaultlibs -nostdlib -fPIC -static -s -L$HOME/build/cross/sys-root/usr/lib -zmuldefs" \
LIBS=" -lm -lc -lgcc -liberty -lgcc_eh -lstdc++" \
--prefix="$HOME/build/cross/sys-root/usr" --with-liblua=included --with-libpcre=included \
--with-libdnet=included --without-ncat --with-libpcap=included --with-pcap=linux ac_cv_linux_vers=2.6.29
Все проходит нормально, но возникли трудности при линковке конечного бинарника:

Уже почти вчера весь вечер бился над исходниками nmap и ничего не вижу - нужен взгляд со стороны. Спасибо!
