Ceph

That error is expected on CentOS 7.2.

Try this.

git clone https://github.com/ceph/ceph.git
cd ceph/
./run-make-check.sh

Hi Brad,

I tried ./run-make-check.sh and still get the same error.

Should I update some lib or something? Thanks!

Hi Jane,

I get that error on centOS 7.2 as well, it's not the problem.

Can you attach the CMakeOutput.log and CMakeError.log files please?

No luck there I'm afraid.

From the ceph directory could you do the following?

rm -rf build
mkdir build && cd $_
cmake .. &> /tmp/cmakeout.txt
cd ..
rm -rf build
mkdir build && cd $_
cmake --trace .. &> /tmp/cmaketraceout.txt

Then compress and upload /tmp/cmakeout.txt and /tmp/cmaketraceout.txt

Here we go.

Could you please paste the output of "rpm -q cmake"

Here is output.

[root@Ctrust tmp]# rpm -q cmake
cmake-2.8.12.2-2.el7.x86_64

OK, that looks fine. I guess, for whatever reason, the subdirectory src/zstd is missing or perhaps empty as the error message suggests or has some other problem causing this message.

Could you try running the following?

git submodule foreach --recursive git clean -fdx
git submodule update --init --recursive

Then try ./run-make-check.sh again.

If that doesn't work please try cloning the ceph repo again and see if the same thing happens with a fresh copy.

Hi Brad,

Thanks for your helpful advice. But I get a new error... After cloning src/zstd, ./run-make-check.sh went well until 97%.

This is the error message:

Besides, I was confused about build ceph. The official doc says these steps are enough:
cd ceph
./install-deps.sh
mkdir build
cd build
cmake ..
make

Should I execute ./do_cmake.sh or anything else after ./run-make-check.sh?

./run-make-check.sh is a script that runs all of the above and also runs the tests (you don't need to do this) so sure, you can run the other commands. It's just easier for me to specify one command that runs all the commands in a known sequence.

Your current problem looks like some issue with a python and pip version mismatch. What versions do you get when you run "python -V" and "pip -V"?

https://bugzilla.redhat.com/show_bug.cgi?id=1417613 is one example I found. On my test system pip is only installed at "/tmp/ceph-disk-virtualenv/bin/pip" and "/tmp/ceph-detect-init-virtualenv/bin/pip"

1. rpm -q pyparsing
   pyparsing-1.5.6-9.el7.noarch
2. rpm -q python2-pip
   package python2-pip is not installed
3. rpm -q python
   python-2.7.5-48.el7.x86_64

Thanks Brad. It seems to be the problem of pip. At first, my enviroment was like this:

[root@Ctrust ceph]# python -V
Python 2.7.5
[root@Ctrust ceph]# pip -V
pip 9.0.1 from /usr/lib/python2.7/site-packages (python 2.7)
[root@Ctrust ceph]# rpm -q pyparsing
pyparsing-1.5.6-9.el7.noarch
[root@Ctrust ceph]# rpm -q python2-pip
package python2-pip is not installed
[root@Ctrust ceph]# rpm -q python
python-2.7.5-48.el7.x86_64

So I tried to install python2-pip, and pip crashed.
Then followed the guide https://bugzilla.redhat.com/show_bug.cgi?id=1416577, and execute these:

yum install ftp://mirror.switch.ch/pool/4/mirror/centos/7.3.1611/cloud/x86_64/openstack-kilo/common/pyparsing-2.0.3-1.el7.noarch.rpm
pip install docutils
pip install --upgrade pip

In the end, ceph was built successfully.

Good to hear Jane.

If it's OK with you I'll close this out then?

Yes， please. Thanks again.
