Hi,
I'm having problems with running Qt5 apps using OE master. I'm using a couple
of other layers, but as the problem seems to be related to libicudata.so I
figured I'd post it here, my apologies if the mail should go somewhere else.
When starting the Qt5 app I get:
error while loading shared libraries: /usr/lib/libicudata.so.51: internal error
I'm building for Wandboard Solo machine from meta-fsl-arm-extra layer.
TUNE_FEATURES = "armv7a vfp neon callconvention-hard cortexa9"
TARGET_FPU = "vfp-neon"
[jkroon@localhost oe-devel]$ readelf -A
build/tmp-eglibc/sysroots/wandboard-solo/usr/lib/libicudata.so.51.2
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
Tag_Advanced_SIMD_arch: NEONv1
this does not seem to be complete output, the key piece thats interesting here
is what is value of Tag_ABI_VFP_args since you say you have call
convention-hard in TUNE_FEATURES
I expect Tag_ABI_VFP_args = VFP registers
Maybe it's odd, but I get the same exact output for the older build,
when things work. Most .so-files show the same output as libicuio.so (also
from the old build):
[jkroon@localhost oe-devel]$ readelf -A
build/tmp-eglibc/sysroots/wandboard-solo/usr/lib/libicuio.so.51.2
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
Tag_Advanced_SIMD_arch: NEONv1
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
So I figure either libicudata.so is not used at
that point, but still incorrectly built, or my problem is not related to
the ELF header flags..
I don't have access to the wandboard right now but I'll try starting
the app via a gdb-server and see if that comes up with anything new.
