Troubleshooting

`ld`, `clang`, `lssl`, or `linker` Errors

If you have an error message like:

ld: library not found for -lssl
clang: error: linker command failed with exit code 1
error: command 'clang' failed with exit status 1

These error messages indicates that there is a problem installing OpenSSL.

This Stack Overflow answer has specific recommendations on setting the LDFLAGS and/or CPPFLAGS environment variables. Set those prior to running meltano add loader target-postgres.
