GLIBC linking issues

[Raj2032]

On Windows I installed cross and docker and managed to compile my project just fine using this command:

cross build --target i686-unknown-linux-gnu --release

However when running this on a 32bit linux operating system I get the following error

./updatesql_email_err
./updatesql_email_err: /lib/libc.so.6: version `GLIBC_2.29' not found (required by ./updatesql_email_err)
./updatesql_email_err: /lib/libc.so.6: version `GLIBC_2.9' not found (required by ./updatesql_email_err)
./updatesql_email_err: /lib/libc.so.6: version `GLIBC_2.16' not found (required by ./updatesql_email_err)
./updatesql_email_err: /lib/libc.so.6: version `GLIBC_2.15' not found (required by ./updatesql_email_err)
./updatesql_email_err: /lib/libc.so.6: version `GLIBC_2.28' not found (required by ./updatesql_email_err)
./updatesql_email_err: /lib/libc.so.6: version `GLIBC_2.18' not found (required by ./updatesql_email_err)

I want to link all this inside the binary itself.

I want to link all this inside the binary itself.

So you probably want to use the i686-unknown-linux-musl target. But it seems that it is not supported by cross-rs. You could build a new image for it. But this target seems to have some problems in general. See here.

Another option is to set the glibc version, so that it is compatible with your target system. See here for more details.
