Hello, Last week, I had to use Crosstool-NG in an environment where HTTP and FTP servers are accessed through a proxy. Unfortunately, the stupid behavior of the proxy combined with how Crosstool-NG fetches tarball didn't play well. Basically, the proxy is stupid enough that when you do "wget ftp://someserver/something", when "something" doesn't exist on "someserver", instead of returning an error, the proxy generates a short HTML page saying "The file does not exist". So wget returns with a successful error code, but the downloaded file is a HTML page and not the expected tarball. Unfortunately, Crosstool-NG has a logic that consists in trying multiple locations for tarballs before finding the right one. Combined with the above mentioned proxy-misfeature, Crosstool-NG ends up thinking that the tarball was downloaded while in fact only a few hundreds bytes of HTML has been downloaded. Crosstool-NG continues its execution, until the extraction step, which of course, fails. This problem occured with the latest stable version of ct-ng, specifically on the gcc and cloog-ppl tarballs. I think ct-ng should do a few more checks on the downloaded files to ensure that they at least remotely look like valid tarballs. For example, check with "file --mime-type" that the file looks valid, or some other similar check. If the file isn't a valid tarball, then the next URL is tried. This would allow to workaround stupid proxies, and make ct-ng even easier to use in so-called corporate environments.
