[directfb-users] cross compiling library icu in buildroot and linked on application , applition outputs nothing

[zhou qiang]

Hi guys ,

I encountered a very strange issue while cross compiling library ICU and
application with linaro arm toolchian generated from Buildroot .
Application works fine without linking ICU , but failed to run and exit
immediately with nothing output in console . I tried to debug with

LD_DEBUG=files ./application

LD_DEBUG=files ./application


347: file=libz.so.1 [0]; needed by ./appliation [0]
347: file=libz.so.1 [0]; generating link map

347: file=libicudata.so.48 [0]; needed by ./application [0]

It seems that application found libicudata.so smoothly , but failed to
generate link map .

ICU library used to work fine on another platform compiling with codesocery
toolchain .
For new project , I downloaded a buildroot-201306 and added linaro-201205
toolchain .

I am wondering is this issue related with linaro toolchain or some bug of
library ICU .

If anyone has faced same situation , please give me some suggestion .

Any advice would be great appreciated as well .
