Version: 1.34<br>
Severity: normal<br>
<br>
Dear Maintainer,<br>
<br>
According to `man dh-golang`:<br>
<br>
 "DH_GOPKG" (string) contains the Go package name which this Debian<br>
 package is building.<br>
<br>
 "DH_GOPKG" is automatically set to the value of the first import path<br>
 of the "XS-Go-Import-Path" "debian/control" field, which can contain<br>
 several comma-separated import paths.<br>
<br>
However, I tried to use this variable in the debian/rules file, in<br>
targets such as `override_dh_auto_test` and `override_dh_auto_build`,<br>
and this variable is empty.<br>
<br>
I added some debug to dh-golang, and I clearly see the code from<br>
`_set_dh_gopkg` being executed, and the variable is set there. So it<br>
looks like the environment in `debian/rules` is unrelated to the<br>
environment that is set by dh-golang.<br>
<br>
If it's expected, then maybe the man page needs a little rewording. If<br>
it's not expected, then it's a bug?<br>
<br>
Regards,<br>
<br>
 Arnaud<br>
