[Question] How to Build in CentOS7?

[andywu106]

Describe the bug

I try to build polycube In CentOS7，but get following error:

Additional context

Is possible to build and run in CentOS7?

Hi @andywu106,
it seems a problem related to BCC and in particular to LLVM, could you try downgrading the version to v9 and see if it compiles correctly?

@andywu106 I have the same problem. Would you like to solve your problem below?

Hi All,

I manage to install the Polycube from source code and no error pops out when compiling.

However, I cannot start the service.
After checking the status, it said "/usr/local/bin/polycubed: error while loading shared libraries: libpistache.so.0: cannot open shared object file: No such file or directory but this library is installed.

sudo find / -name libpistache.so.0
/root/pistache/build/src/libpistache.so.0
/usr/local/lib64/libpistache.so.0

I tried to export the path to the LD_LIBRARY_PATH but it did not work.

echo $LD_LIBRARY_PATH
/opt/rh/llvm-toolset-7/root/usr/lib64:/opt/rh/devtoolset-8/root/usr/lib64:/opt/rh/devtoolset-8/root/usr/lib:/opt/rh/devtoolset-8/root/usr/lib64/dyninst:/opt/rh/devtoolset-8/root/usr/lib/dyninst:/opt/rh/devtoolset-8/root/usr/lib64:/opt/rh/devtoolset-8/root/usr/lib:/usr/local/lib64

My environment

OS details: CentOS Linux release 7.6
Kernel details: 5.4.226-1.el7.elrepo.x86_64
LLVM version: 5.0.1
GCC version: 8.3.1
cmake version: 3.25

This is how I install.

Hi All,

I figure it out.

I edit the /etc/ld.so.conf file and put the following directory into it.

echo /usr/local/lib64
echo /usr/local/lib
echo /opt/rh/llvm-toolset-7/root/usr/lib64/
echo /opt/rh/llvm-toolset-7/root/usr/lib/
ldconfig

Now, I got this error when starting Polycubed.
