smf build fails on linux mint 18

c++ (Ubuntu/Linaro 6.3.0-18ubuntu2~16.04) 6.3.0 20170519.

build log

I tried installing g++-7 c++ (Ubuntu 7.2.0-1ubuntu1~16.04) 7.2.0

build log

[emaxerrno]

Got it! thanks. looking into it.

[crackcomm]

@senior7515 I kept looking and I see /usr/include/c++/6 - probably it?

[emaxerrno]

could be, i've tested w/ gcc6.

can you cd build_debug && ninja -j1

[crackcomm]

I did sudo mv /usr/include/c++/6 /usr/include/c++/6-not-used and cd build_debug && ninja -j1, same error.

seastar is failing, https://travis-ci.org/scylladb/seastar/jobs/347447890

can you try this git hash: on seastar: 0ed15e9

[crackcomm]

@senior7515 this is weird, seastar compiled fine, earlier with g++ 6.3.0.

I will try at 0ed15e9.

[dotnwat]

that's weird. the seastar version is pegged in ci (https://github.com/senior7515/smf/blob/master/ci/base/Dockerfile#L13), i wonder why its failing on travis

[crackcomm]

here is the log this time: https://gist.github.com/crackcomm/3285f7c45071ec98f6ec9d7f90706353

[emaxerrno]

thanks @crackcomm ... pretty helpful. Trying to repro locally.

[emaxerrno]

@noahdesu - good point. will try to build locally at this revision and see if I can repro

[emaxerrno]

good news, is I can repro at that git hash of seastar!

[emaxerrno]

fix on the way. thanks!

[crackcomm]

@senior7515 thanks, in fact it fixed the error

still, the previous error remains: https://gist.github.com/crackcomm/7f83ed85c6f50897c5f384614c70be6e

[emaxerrno]

ok that's good. (re: bugfix/ci). Have you by chance tried the latest seastar hash now that that bug is gone, and or the one on the dockerfile.

once i can get a reproducible bug on my machine, I can fix it.

thanks!

[crackcomm]

seastar master log: https://gist.github.com/crackcomm/b0bd049ec294869eddaea35c202b813b

[dotnwat]

Perhaps we can reproduce in docker. Are you running Linux mint? Which version etc? On Wed, Feb 28, 2018 at 17:05 Łukasz Kurowski notifications@github.com wrote:

Linux Mint 18.2 Sonya

[emaxerrno]

Will try to repro w/ docker. thanks @crackcomm !

[crackcomm]

let me know if I can be helpful somehow

[emaxerrno]

tried running on docker, and not getting very far tonight... :'( will keep hacking on it this week.

I did notice a few things. linux mint 18 is basically ubuntu xenial - which should actually just work :'( - i think i was running some weird docker image. Do you have a good ref for linuxmint:18 - doing a docker search for it didn't return trust worthy results.

do you mind manually setting these 2 variables (on $SMF_ROOT/CMakeLists.txt)

SET(CMAKE_C_COMPILER /path/to/c/compiler)
SET(CMAKE_CXX_COMPILER /path/to/cpp/compiler)

to a later gcc - say gcc6 to test it out.

make sure you also set the --compiler=gcc-6 on seastar too

[emaxerrno]

I tried building on this: https://hub.docker.com/r/linuxmintd/mint18-amd64/tags/

and i keep getting errors related to this:

2184a311eeda smf # sudo add-apt-repository ppa:ubuntu-toolchain-r/test
Traceback (most recent call last):
  File "/usr/lib/linuxmint/mintSources/mintSources.py", line 25, in <module>
    import gi
ImportError: No module named gi

I also tried the other one https://hub.docker.com/r/vcatechnology/linux-mint/tags/ tag 18.2 - same with this https://hub.docker.com/r/fabiohbarbosa/linux-mint/tags/

but no cigar

73884893c3d8 / # add-apt-repository ppa:ubuntu-toolchain-r/test
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display

maybe you can push a docker image and I can download it and repro it.

[emaxerrno]

@crackcomm let me know if you manage to push a docker image and I will fix it tonight.

[crackcomm]

@senior7515 I am going to test it out, with gcc-6

I already have some weird noise in here:

➜  seastar git:(master) ✗ python3 configure.py --compiler=g++-6
Notice: -fsanitize=vptr is broken, disabling; some debug mode tests are bypassed.
Notice: disabling -Wattributes due to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80947
Seastar requires g++ >= 4.9.  Install g++-4.9 or later (use --compiler option).

g++-7:

➜  seastar git:(master) ✗ python3 configure.py --compiler=g++-7
Notice: -fsanitize=vptr is broken, disabling; some debug mode tests are bypassed.
Notice: disabling -Wattributes due to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80947

I am having some trouble with CMake, I will re-pull and build.

What would you want me to include in a Docker image?

[crackcomm]

Is there some easy way to build a docker image from my entire OS?

[crackcomm]

I think this has to be some incompatibility with C++ tool-chain in Mint packages.

Here is my repos list, can't find a good, other image of mint than you found.

I am now rebuilding seastar with gcc-6 and later smf with gcc-6, previously there might've been some incompatibility as I had to update CMake to build smf and later install g++-7.

I have to admit the error from the C++ compiler does not make too much sense for me but correct me if I'm wrong, this error origins from seastar source code distributed.hh and httpd.hh and not in smf? It seems odd because seastar compiled fine and I even made a quick comparison between seastar httpd ad Go net/http.

I wish I could help more but I am not sure what I can do, thank you for your support.

[crackcomm]

I tried to build on Ubuntu 16.04 in Docker on VPS, here is the build log. reproducable easily with history which includes installing dependencies from seastar install-dependencies.sh and smf install-deps.sh.

[dotnwat]

i removed xenial from travis-ci at some point as either (1) stock gcc was too old or (2) needed some additional setup in cmake. that would explain the issue, as i thought xenial was still active in ci. we should add a xenial config to the travis config file

[dotnwat]

https://travis-ci.org/noahdesu/smf/jobs/348003612

[crackcomm]

@noahdesu both :)

I was able to build on docker image mentioned previously by doing

apt-get remove g++-5
apt-get install g++-7-multilib
apt autoremove

[dotnwat]

cool cool. so, this is really easy to hack into the travis-ci for on going testing. thanks for narrowing this down. in terms of fixes, i wonder if this is just a documentation fix: "if you are using xenial or mint, you need to upgrade gcc" ?

[crackcomm]

also remove old libstdc++

[dotnwat]

maybe can skip removing g++5 and libstdc++ by using update-alternatives, but haven't tested: https://github.com/ceph/ceph/blob/master/install-deps.sh#L63

[crackcomm]

it only updates binaries location not libstdc++ and only after removing it it worked out. if you could somehow do same with libraries then it could work out

[crackcomm]

problem is also apt-get install -qy g++-7 does not install these std libs but apt-get install g++-7-multilib

[emaxerrno]

thank you @crackcomm - great tracking down!!! let's definitely track this in the travis script!

w00t! excited to have you up and running!

[emaxerrno]

@crackcomm - are you thinking of submitting a PR for the multilib and ubunu:xenial ?

[crackcomm]

@senior7515 I am not sure, do you mean adding install in ci/base/Dockerfile and ubuntu:xenial in .travis.yml? or install in install-deps.sh?

[emaxerrno]

oh just thinking of getting .travis.yml working with ubuntu:xenial
