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
