[h323plus] Compiling PTLib 2.10.1 in Ubuntu 11

Hi again:

I've found these libs installed: 
/lib/i386-linux-gnu/libpthread-2.13.so  /lib/i386-linux-gnu/libpthread.so.0

So I've run: ./configure --libdir=/lib/i386-linux-gnu

But I still get the "must have pthreads!" error.

Regards,

Thank you, Piyush. But it seems that I've that installed already:

sudo apt-get install libpthread-stubs0-dev
[sudo] password for xxxxxxx:

libpthread-stubs0-dev is already the newest version.
libpthread-stubs0-dev set to manually installed.

Hi,

Try to install  libpthread-stubs0-dev.

sudo apt-get install libpthread-stubs0-dev.

pthread stubs not provided by native libc, development files.

Thanks & Regards
