Is it possible to use the FreeBSD libthr.a library file on a Redhat Linux box?

["Srinivas G." <srinivasg@xxxxxxxxxxxxxxxxxxxxx>]

Dear All,

I have written an application where I have used the libpthread library
for creating the pthreads. However, to get the maximum optimization, I
want to use the libthr.a library instead of libpthread library. However,
when I tried to use on my Redhat box, I end up with following errors.

../lib/linux/libthr.a(thr_sem.o): In function `_sem_init':
thr_sem.c:(.text+0x100): undefined reference to `ksem_init'
thr_sem.c:(.text+0x115): undefined reference to `ksem_destroy'
../lib/linux/libthr.a(thr_sem.o): In function `_sem_destroy':
thr_sem.c:(.text+0x216): undefined reference to `ksem_destroy'
../lib/linux/libthr.a(thr_sem.o): In function `_sem_timedwait':
thr_sem.c:(.text+0x2ad): undefined reference to `ksem_timedwait'
../lib/linux/libthr.a(thr_sem.o): In function `_sem_wait':
....
....
....

collect2: ld returned 1 exit status
make: *** [target] Error 1

I understand that the "ksem_init" is not available on the Redhat box.
Then, I have tried to use the libc.so.7 from FreeBSD. I have included
the libc.so.7 in my application to getridof the above undefined
references. Even though, I end up with the following errors.

/usr/bin/ld: errno@@FBSD_1.0: TLS definition in /lib/libc.so.6 section 
.tbss mismatches non-TLS definition in ../lib/linux/libc.so section 
.bss
/lib/libc.so.6: could not read symbols: Bad value

Here, the lib/libc.so.6 is a Redhat libc library where as 
../lib/linux/libc.so is a FreeBSD library (libc.so.7). 

Is it possible to use the FreeBSD libthr.a library file on a Redhat
Linux box? 

Please let me know the whether it is possible to use the libthr.a
library on Redhat box or not.

Thanks in advance.

With Regards,
Srinivas G
