<div>As you've guessed, it's the linkage.</div>
<br>
<div>"common" is the name for the C situation where multiple source files</div>
<div>simply declare "int a;" with nothing else specified. The names get</div>
<div>merged, and the variable gets zero-initialized by default. A "real"</div>
<div>definition (like you're trying to provide) would take precedence over</div>
<div>this and specify the actual data.</div>
<br>
<div>You almost certainly want GlobalValue::ExternalLinkage for a</div>
<div>bog-standard global variable.</div>
