 |
|
Hi,
I write a simple ebuild which just download their tarball and run "make all". The "ebuild ... install" command works without any error and create the correct file layout in the "image" directory.
But when I try to emerge the package to my live system, I got "curl: (6) Could not resolve host: github.com" constantly. Even it occasionally got resolved, the download will be interrupted and fail.
The "curl" command is NOT issued by the ebuild, but by the "Makefile" from the tarball. I wonder if gentoo has any restriction on running "curl" during emerge.
By the way, my host system can access the network normally. So I don't think it is my host network issue.

Yes, there are restrictions for curl, wget and all the programs alike. Everything should be downloaded via the standard ebuild means (SRC_URI etc). It was discussed on the forum some months earlier.

| This is a defect in the upstream build system. It should not be downloading anything as part of make. You may be able to discourage it from doing this with a configuration parameter or by having the ebuild arrange for the required dependencies to be available before calling emake. |
