Build error

[skyelves]

When I run ./contrib/build.sh -j -T, an error is thrown:

[ 94%] Linking CXX shared library libfolly.so
/usr/bin/ld: /usr/local/lib/libfmt.a(format.cc.o): relocation R_X86_64_PC32 against symbol `stderr@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC

I tried -DCMAKE_POSITION_INDEPENDENT_CODE=TRUE and -fPIC and it doesn't work.

I try to build and install all the independencies separately. And I seem to successfully install all of them, though with great effort. Then I successfully run ./contrib/build-package.sh -j -i -d -v -t cachelib and it says 'cachelib' is now installed.
However, when I try the command ./bin/cachebench --help
it returns ./bin/cachebench: symbol lookup error: ./bin/cachebench: undefined symbol: _ZN6google21kLogSiteUninitializedE Have no idea about the problem.

It seems CacheLib relies an certain versions of its dependencies such as glogs and fmt. Can anyone specify the versions of them?

cc @agordon for information on that.

Can you share which platform you are trying this on ? We have github actions building the repo on a few platforms (ubuntu, debian, centos) and they seem to be green (except for the ubuntu one which looks like a configuration error).

I am working on Ubuntu 18.04, 4.15.0-156-generic, with
gcc (Ubuntu 7.5.0-3ubuntu1 18.04) 7.5.0
g++ (Ubuntu 7.5.0-3ubuntu1 18.04) 7.5.0

@skyelves, it seems you have glog or fmt installed on the system (using apt-get) - this might be the reason for the conflict.
CacheLib indeed uses its own versions of all packages (compiled and installed into a user subdirectory, so never override the system ones). This error hints to me we need to improve our build script to force it to ignore system-wide installation - I'll have a patch for that soon.

BTW,
For glog we use version 0.5.0 - the last official release (see here: https://github.com/facebook/CacheLib/blob/main/contrib/build-package.sh#L120 ).
For fmt - we use the latest git commit.

Thanks, I have figured out the problem. Actually I am trying to build all the wrong dependencies myself.
The first problem is because I didn't built the libfmt as a share lib so the link failed. After I built the libfmt as the shared lib, it works, though another problem occurs.

@skyelves - thanks for the update.

May I ask, was there a technical reason you tried to build the dependencies yourself?
The build script (./contrib/build.sh) should take care of all the dependencies under normal conditions. was something not working?
Or perhaps our documentation isn't clear about it?

Thanks for the reply! I have successfully built the CacheLib and ran the benchmark. In a nutshell, my problems come from two aspects.

1. inconsistent libboost version.
2. glog and fmt already installed on my server, which are built as static lib with different version.

Just as you mentioned before, "This error hints to me we need to improve our build script to force it to ignore system-wide installation - I'll have a patch for that soon." This would be quite beneficial for cases like me.
Thanks again for your help!
