c++ - How to change arm version in arm-linux-gnueabi-gcc for cross compile -


i want cross-compile in eclipse board armv7l. got armv7l via, uname -i. installed arm cross compiler toolchain, using below commands. 

$ sudo apt-get install emdebian-archive-keyring $ sudo apt-get install libc6-armel-cross libc6-dev-armel-cross $ sudo apt-get install binutils-arm-linux-gnueabi $ sudo apt-get install gcc-arm-linux-gnueabi $ sudo apt-get install g++-arm-linux-gnueabi $ sudo apt-get install u-boot-tools $ sudo apt-get install libncurses5-dev

i think have give option target board version.

first time tried put arm-linux-gnueabi-g++ in c/c++ build->settings->gcc c++ compiler , gcc c++ linker.(eclipse project properties)

next put -march=armv7 in miscellaneous

but not working. checked executable file readelf -a , shows 

  tag_cpu_name: "7-a"   tag_cpu_arch: v7   tag_cpu_arch_profile: application   tag_arm_isa_use: yes   tag_thumb_isa_use: thumb-2   tag_fp_arch: vfpv3-d16   tag_abi_pcs_wchar_t: 4   tag_abi_fp_denormal: needed   tag_abi_fp_exceptions: needed   tag_abi_fp_number_model: ieee 754   tag_abi_align_needed: 8-byte   tag_abi_align_preserved: 8-byte, except leaf sp   tag_abi_enum_size: int   tag_abi_hardfp_use: sp , dp   tag_cpu_unaligned_access: v6   tag_div_use: not allowed

what option have put target board ?

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
