undefined reference to `__aeabi_f2uiz'

[ganhpt]

Hi All,

I have some native c source code and I wanted to convert it into a
library for Android Application.

I compiled the source code using NDK toolchain(arm-eabi-4.2.1). and I
created the archive (libExample.a).

Now, I want to create a shared library by linking to the above
created archive.
In Android.mk , I am assigning path to archive

TARGET_LDLIBS := -Wl, <path-to-archive>/libExample.a

But, NDK is throwing the below error :

undefined reference to `__aeabi_f2uiz'

This error message refers to the below statement in the source

NoFragUnits = ((float)(TotalSize)/unitSize) + 1;

where,
NoFragUnits => int
TotalSize => int
unitSize => short


Could anyone help me to resolve this....


Thanks & Regards
Ganesh

I'm not sure I see the need for using a floating point division in the example you posted. It's not scaling the quota before converting it back to int, so any fractional digits will be lost all the same. (consider   3/5 == 0  vs  3.0/5.0 == 0.6, (int)0.6 == 0).

You should either be using:
LOCAL_LDFLAGS := <path-to-archive>/libExample.a
or
LOCAL_LDFLAGS := '-L$<path-to-archive>/' '-lexample'

I was facing the same problem "undefined reference to `__aeabi_f2uiz'"

I use custom makefiles. Including libgcc.a solved this problem.

 

you can check presence of the function in the library

#arm-eabi-nm $(NDK_HOME)/build/prebuilt/linux-x86/arm-eabi-4.x.x/lib/gcc/arm-eabi/4.x.x/interwork/libgcc.a | grep __aeabi_f2uiz
