BR2_GCC_VERSION_4_1_2=y .. BR2_GCC_VERSION="4.1.2" BR2_SOFT_FLOAT=y It compiled successfully but readelf -h build_arm/staging_dir/lib/libuClibc-0.9.29.so ELF Header: Magic: 7f 45 4c 46 01 01 01 61 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: ARM ABI Version: 0 Type: DYN (Shared object file) Machine: ARM Version: 0x1 Entry point address: 0xa520 Start of program headers: 52 (bytes into file) Start of section headers: 525932 (bytes into file) Flags: 0x202, has entry point, GNU EABI, software FP Size of this header: 52 (bytes) Size of program headers: 32 (bytes) Number of program headers: 6 Size of section headers: 40 (bytes) Number of section headers: 23 Section header string table index: 22 Seems I get anyway EABI not OABI. Can you confirm this? seems like "arm gcc-4.1.2 + oabi + soft floats fails to build" should be treated as "arm gcc-4.1.2 + EABI + soft floats fails to build" ?
