About Error: could not find pthread_yield function

[Kang-ian]

When I downloaded and installed BGPStream according to the documentation, and entered ./configure, I encountered an error: "error: could not find pthread_yield function." I originally intended to replace all "pthread_yield" with the "sched_yield" function. However, I found no "pthread_yield function" in my configure.ac file. How should I proceed?

Hi,

I managed to find a solution from various sources

git clone https://github.com/CAIDA/libbgpstream.git
cd libbgpstream/
git checkout tags/v2.2.0

apt install autogen autoconf libtool

# Remove the duplicated "AM_INIT_AUTOMAKE" in the file configure.ac
# cat configure.ac | grep AM_INIT_AUTOMAKE -> Will show 2 "AM_INIT_AUTOMAKE"
awk '/AM_INIT_AUTOMAKE/ {count++; if (count > 1) next} {print}' configure.ac > configure.ac.new && mv configure.ac.new configure.ac
# cat configure.ac | grep AM_INIT_AUTOMAKE -> Will now show only one "AM_INIT_AUTOMAKE"

# Replace the content of the file "m4/ax_pthread.m4" with this https://github.com/CAIDA/libbgpstream/blob/2bce0f679c1703ef154588782af250ccd30c012e/m4/ax_pthread.m4
wget -O m4/ax_pthread.m4 https://raw.githubusercontent.com/CAIDA/libbgpstream/2bce0f679c1703ef154588782af250ccd30c012e/m4/ax_pthread.m4

./autogen.sh
./configure

make
make install

Hope this helps!
