/** Helps detect version mismatches between libpqxx headers and the libpqxx
|
|
* library binary.
|
|
*
|
|
* Sometimes users run into trouble linking their code against libpqxx because
|
|
* they build their own libpqxx, but the system also has a different version
|
|
* installed. The declarations in the headers against which they compile their
|
|
* code will differ from the ones used to build the libpqxx version they're
|
|
* using, leading to confusing link errors. The solution is to generate a link
|
|
* error when the libpqxx binary is not the same version as the libpqxx headers
|
|
* used to compile the code.
|
|
*
|
|
* This function's definition is in the libpqxx binary, so it's based on the
|
|
* version as found in the binary. The headers contain a call to the function,
|
|
* whose name contains the libpqxx version as found in the headers. (The
|
|
* library build process will use its own local headers even if another version
|
|
* of the headers is installed on the system.)
|
|
*
|
|
* If the libpqxx binary was compiled for a different version than the user's
|
|
* code, linking will fail with an error: `check_pqxx_version_*_*` will not
|
|
* exist for the given version number.
