Also, at this URL, BEPF dependencies are listed if one would like to use
EBPF.

 

https://github.com/p4lang/p4c/blob/master/backends/ebpf/README.md

 

$ sudo apt-get install clang llvm libpcap-dev libelf-dev iproute2 net-tools

$ sudo pip install pyroute2 ply scapy

Xiaoban,

 

Try running cmake with EBPF switched off "cmake .. -DENABLE_EBPF=OFF". Could
be caused by https://github.com/p4lang/p4c/issues/1376

Dear All,

 

I am trying to install p4c on ubuntu 16.04.1 with kernel 4.15.0-36-generic.
However, I could not get a success after many trials. Can anyone please help
me point out the possible issue? Thanks very much.

 

Alternative approach, could anyone tell me your OS and kernel version that
works for you, then I will try to follow your setup? Thanks very much.

 

Best wishes,

Xiaoban

 

First, I did "

git clone --recursive https://github.com/p4lang/p4c.git

" 

 

Second, I did "sudo apt-get install cmake g++ git automake libtool libgc-dev
bison flex libfl-dev libgmp-dev libboost-dev libboost-iostreams-dev
libboost-graph-dev llvm pkg-config python python-scapy python-ipaddr
python-ply tcpdump"

 

Third, I did "

$ git clone https://github.com/protocolbuffers/protobuf.git
$ cd protobuf
$ git submodule update --init --recursive

  $ git checkout v3.2.0

$ ./autogen.sh
$ ./configure
$ make
$ make check
$ sudo make install
$ sudo ldconfig # refresh shared library cache.

" 

 

Fourth, I did "

mkdir build
cd build
cmake ..

" 

Then I saw these logs on the screen
