我在armhf ubuntu目标(arm9,omap4)上遇到了以下问题。我正在尝试使用Ubuntu 12.04 arm-linux-gnueabihf工具链来执行maliit键盘。我成功地交叉编译的Qt5和maliit-framework使用的不同库,但是当执行maliit-server或maliit-exampleapp-plainqt时,它在动态库打开后立即退出。这是strace输出的结束:
open("/mnt/internal/library/icu_4.8.1.1/lib/libicudata.so.48", O_RDONLY|O_CLOEXEC) = 3
read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0(\0\1\0\0\0T\2\0\0004\0\0\0"..., 512) = 512
lseek(3, 18280604, SEEK_SET) = 18280604
read(3, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 480) = 480
lseek(3, 18280460, SEEK_SET) = 18280460
read(3, "A \0\0\0aeabi\0\1\26\0\0\0\0057-A\0\6\n\7A\10\1\t\2\n\4,"..., 33) = 33
exit_group(1) = ?
+++ exited with 1 +++
我首先认为它与不同库之间的arm浮点不兼容有关,但是库上的readelf -h给了我这个(除了其中一些有Tag_ABI_optimization_goals:Aggressive Speed):
Attribute Section: aeabi
File Attributes
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 and DP
Tag_ABI_VFP_args: VFP registers
Tag_CPU_unaligned_access: v6
Tag_DIV_use: Not allowed
我可以通过strace看到已找到所有库。在strace上获得“aeabi”给出了以下输出:

ldd也退出而不显示所需的所有不同库并返回1.
有谁知道这里发生了什么?
