Fwd: pthread_barrier_wait help

[Jagadish_gmail <jagadishkotra at gmail dot com>]

Hello,

   I have installed glibc using the following command ..

   I have added my new function pthread_barrier_wait_jag()

  bash$pwd
   /home/jbk5155/glibc/glibc-build/
 bash$../glibc-2.15/configure --prefix=/home/jbk5155/glibc/glibc-build/ 
--enable-addon=pthread
  ......
  ......
  .....
  <configure successful>
  bash$sudo make
  <make was successful>
  bash$sudo make install
  <make install was successful>

   I see my function being listed with nm command listed below ..

  nm libpthread.so.0 | grep "jag"

    but when I try to compile my testcase with 
-L/home/jbk5155/glibc/glibc-build/ -lpthread ... testcase compiled 
successfully but when I do a ldd I still see the default libpthread.so.0 
is being picked up

jbk5155@jbk5155:~/splash/codes/kernels/fft$ ldd FFT
    linux-gate.so.1 =>  (0xb7741000)
    libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xb7712000)
    libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xb76e6000)
    libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb753b000)
    /lib/ld-linux.so.2 (0xb7742000)

and hence when I run it my testcase crashes saying 
pthread_barrier_wait_jag() is not found. Can you please let me know what 
I am doing wrong?

Thanks and Regards,
Jagadish.

Hello,

  I am a graduate student and I am looking for some help with glibc. I
am working on a project where I am trying to modify
pthread_barrier_wait.c() code. I see that the hand-optimized
pthread_barrier_wait.S (assembler version) is currently being used as I
am on X86 architecture.

I want my build scripts to use the generic pthread_barrier_wait.c
instead of the hand-optimized pthread_barrier_wait.S.

Can you please let me know what changes do I need to make to use this c
version of the code instead of the hand-optimized assembler version ?

Thanks and Regards,
Jagadish
