curl build failure

I was trying my luck at building an RPi3 compatible version of curl on the autobuilder. (A wget build worked perfectly.)

It stopped :-

This http does not look right – http://libgcrypt20_1.7.5.orig.tar.bz2.asc/

Google finds the file thus :-

http://http.debian.net/debian/pool/main/libg/libgcrypt20/libgcrypt20_1.7.5.orig.tar.bz2.asc

The internals of the autobuilder continue to baffle, if I could find where the call was coming from I could have attempted a fix but ….

Help!!

The problem was in fetch-program which is now fixed. There are still a couple more problems that need fixing before it will build.

In the mean time you can download an RPi 3 compatible version from here.

Noting the recent libgnutils30 commit to the autobuilder I tried my luck with a further curl build.

There is something familiar about that. I applied this to fetch-program.

orig=$((grep \.orig\.tar\.xz$ files || grep \.tar\.xz files) | cut -d ' ' -f 4)

curl then built. (I guess the second grep should be grep \.tar\.xz$.)
