Dear All,

Thanks very much for your input and help. I have solved this issue and the following is what I did.

1. First, I tried the bash script at  https://github.com/jafingerhut/p4-guide/blob/master/bin/install-p4dev.sh#L67<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_jafingerhut_p4-2Dguide_blob_master_bin_install-2Dp4dev.sh-23L67&d=DwMFAg&c=UycKcnKpT5zzKpcCVf29TA&r=NAfqbdZpYio_GjgwEysEgS0WV4l9eSbIbehFm-ZuE3w&m=c-QkuBocoahB2ssAhynowLXUM7Q0jlcT866PAyp3598&s=aAO-DAz0g_ReAUbxt_AMryb_Ju9ZGlvtsP_pOU10Ffs&e=>, unfortunately, it still errors at the cmake of llvm part.

2. Then I followed the link at https://stackoverflow.com/questions/38171543/error-when-using-cmake-with-llvm which directed me to https://github.com/abenkhadra/llvm-pass-tutorial. From then I manually downloaded llvm and installed it.

wget http://releases.llvm.org/3.8.0/llvm-3.8.0.src.tar.xz

tar -xvf llvm-3.8.0.src.tar.xz

cd llvm-3.8.0.src

mkdir build

cd build

cmake ..

make -j12

sudo make install


3. I changed the backends/ebpf/CMakeLists.txt line 111 into

set(LLVM_DIR /usr/local/*)

find_package(LLVM QUIET)


4. cmake again, there is no more error.

Best wishes,
Xiaoban

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

Xiaoban,



Try running cmake with EBPF switched off "cmake .. -DENABLE_EBPF=OFF". Could be caused by https://github.com/p4lang/p4c/issues/1376<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_p4lang_p4c_issues_1376&d=DwMFAg&c=UycKcnKpT5zzKpcCVf29TA&r=NAfqbdZpYio_GjgwEysEgS0WV4l9eSbIbehFm-ZuE3w&m=lpDLCvyDuz7VWdfRuZILKC5layjEZ_JEjXyUe0qZKBc&s=0vMCMDotkBUccRI3Z4Fcg5p6iQIa0ZSUlyusEsbNXv0&e=>

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<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_p4lang_p4c.git&d=DwMFAg&c=UycKcnKpT5zzKpcCVf29TA&r=NAfqbdZpYio_GjgwEysEgS0WV4l9eSbIbehFm-ZuE3w&m=lpDLCvyDuz7VWdfRuZILKC5layjEZ_JEjXyUe0qZKBc&s=LodY57pCeWGdivdqeKHNmEuSPbD7mq8D8bqZJZWS1mE&e=>

"



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<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_protocolbuffers_protobuf.git&d=DwMFAg&c=UycKcnKpT5zzKpcCVf29TA&r=NAfqbdZpYio_GjgwEysEgS0WV4l9eSbIbehFm-ZuE3w&m=lpDLCvyDuz7VWdfRuZILKC5layjEZ_JEjXyUe0qZKBc&s=YPLHKDjJmbsMyw3iyyxASbzUBBgEcIZBqSE-Mfrg1eo&e=>

$ 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
