[P4-dev] p4c CMake Failed

Xiaoban,

 

If possible, I would cleanup your disk and use Andy's script below to
install all software related to p4c and the behavioral model (bmv2).  The
behavior-model is also needed because a few hundred p4c tests need bmv2
installed on the machine. 

 

 
https://github.com/jafingerhut/p4-guide/blob/master/bin/install-p4dev.sh#L67

 

I and my colleague have used Andy's script and it works like a charm.  My
colleague uses Ubuntu 16.04 and I use 18.04.  A kernel such as yours in
4.15xxx should be fine.

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

Then I checked the CMakeError.log, it says "
