Make sure your embedded fs contain all the libs needed by the application.
You can execute arm_v5t_le-ldd command on the host to query the libs required
by the app.
e.g to run the pthread app I did the following
1. compiled app on Host machine
# arm_v5t_le-gcc thread_test.c -lpthread
# arm_v5t_le-ldd a.out
libpthread.so.0
=>/opt/mv_pro_4.0/montavista/pro/devkit/arm/v5t_le/target/lib/libpthre ad.so.0
(0xdead1000)
libc.so.6 =>
/opt/mv_pro_4.0/montavista/pro/devkit/arm/v5t_le/target/lib/libc.so.6
(0xdead2000)
ld-linux.so.3 =>
/opt/mv_pro_4.0/montavista/pro/devkit/arm/v5t_le/target/lib/ld- linux.so.3
(0xdead3000)
2. My embedded fs contain libc.so.6 and ld-linux.so.3 files.
3. copy libpthread-0.10.so from host to embedded fs and create a symbolic link
to libpthread.so.0
4. execute pthread app.

Subject: pthread function in different filesystem... :(
It's about the pthread function in different
filesystems.
Case 1: (Works!)
If i use the filesystem in davinci DVEVM CD package,
it's about 1GB , the pthread function i use works
fine.
Case 2: (Fail!)
But for the embedded version of filesystem (
SPRAAH2.pdf ) ,
my thread function cannot work.
Both cases are compiled and linked without warning and
error.
Originally , I doubt it's the library issue with my
embedded system filesystem.
So i copy the lib*thread* in filesystem from the case
1 to my case 2. ( located in /lib )
But it still fails...
What's wrong with the case 2 version???
Could someone give me a hint?
