Compatibility issues with rocky 8.5

[andreacarotti331]

Dear all, I'm at University of Perugia (ITLAY),
I'm running an OS Rocky 8.5 that ships with gcc 2.28.
When running the precompiled unidock exec I have this errors.

./unidock: /lib64/libm.so.6: version `GLIBC_2.29' not found (required by ./unidock)

./unidock: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by ./unidock)

Could you compile it with the static option? or can you suggest me how to overcome this issue.
Thanks
Andrea

Hi @andreacarotti331 ,
Would you try installing gcc-9 to match the glibc version? The exetutable is compiled using gcc 9.4.0, fyi.

[andreacarotti331]

Hi,
it's not so simple to upgrade the gcc...usually this means the risk to break something is high.
By the way I managed to workaround by following this answer https://stackoverflow.com/a/61738375.
I downloaded two rpm (libstdc++-11.3.1-4.3.el9.x86_64.rpm and glibc-2.34-68.el9.x86_64.rpm) and extracted by rpm2cpio in a private local folder. Now the program is running.

Maybe we can compile Uni-Dock using older glibc version to solve this problem and similar problem on CentOS with old versions. @caic99

[andreacarotti331]

I think it would be better if you don't prove the source code.
You have two option:

• compile with static libraries so it will be "release independent" , but you have to check if the performances are mantained
• compile with older glibc version and create different unidock binaries...
  My bests

Hi, got the same issue here

We have compiled Uni-Dock with glibc 2.17.
unidock_glibc2_17.zip

Hi, this 2.17 build brings up more dependencies I don't have. I checked this with ldd unidock_glibc2_17:

$ ldd unidock_glibc2_17

Please have a look at the missing dependencies starting with libboost*. I have 1.65 on the system but not 1.77. Are those dependencies really needed? I don't see them in the original binary build
