Error on ser --help? Can you tell me about your

• Servicer version (ser --version)
• Operating system
• Did install the binary or built from source with cargo?

I had same issue, ubuntu 20.04 by default has glibc 2.31. You can upgrade it using:

apt-get install gawk bison gcc make -y
wget -c https://ftp.gnu.org/gnu/glibc/glibc-2.34.tar.gz
tar -zxvf glibc-2.34.tar.gz && cd glibc-2.34
mkdir glibc-build && cd glibc-build
../configure --prefix=/opt/glibc
make
make install

[rizrmd]

But I hope servicer has binary compiled with glibc 2.31. So I don't have to install entire rust toolchain or upgrading my glibc.

The compiled binary picks the libc version from the system where the code was compiled. GLIBC_2.34 could be coming from the Github worker. @ethereumdegen @rizrmd can you try building from source using cargo install servicer?

From stackoverflow

Per the issue: https://github.com/rust-lang/rust/issues/57497 - there's no way to tell the Rust compiler to link a different library other than the one installed on the system.

This means I have to compile the binary on a system that has a less recent version of libc6 installed...
