Arch Linux User Repository

I tried building in a clean chroot, but it still doesn't work

I don't think it's a serious problem anymore though, since I can still download the zip manually and hand it over to makepkg.

❯ mkdir $CHROOT
❯ mkarchroot $CHROOT/root base-devel
❯ arch-nspawn $CHROOT/root pacman -Syu

@Meow0x7E I have no idea why it is not working for you, sorry. You can try to build the package in a clean chroot and check if it works (it should work).

I tried running the _srcurl part separately after adding the --verbose parameter to curl and it returned a 301 redirected html

I tried accessing http://www.blackmagicdesign.com/api/register/us/download/ directly with my browser f874ba6ae24e436fba84e3be19d2caff, but the page says page not found.

I tried accessing https://www.blackmagicdesign.com/support/download/3e5783ec92f34cd19791dcca353c7b79/Linux again and manually filled in _reqjson. This time I got a zip named Blackmagic_DeckLink_SDK_14.2.zip, I tried to manually move the zip to a directory on the same level as PKGBUILD and ran makepkg -si again this time without any problems. Everything executes normally and I'm not sure what's interfering with curl getting the links. What other information can I give you to analyze?

@Meow0x7E I cannot reproduce your issue. I've just checked with the exact same command you provided, and the package is building fine. Sources are being downloaded without any problem.

When trying to build this package makepkg reports an error and then the build fails. can you fix it?

@TurnoffNOD I've just checked, and the package is building fine. Your log shows that you are using an AUR helper, and this is not supported. Please use makepkg.

Hi, the latest PKGBUILD still build failed:

I have checked the PKGBUILD, found the "ERROR" line, which is source=("Blackmagic_DeckLink_SDK_${pkgver}.zip"::"$_srcurl").

Then I execute this curl (what _srccurl is) command in the terminal, variables manually set its value, which becomes commandline

curl -s -H "User-Agent: Mozilla/5.0 (X11; Linux ${CARCH}) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.5735.198 Safari/537.36" -H 'Content-Type: application/json;charset=UTF-8' -H "Referer: https://www.blackmagicdesign.com/support/download/8dbc1e1a31924df7ad46cfa4a8e08ce1/Linux" --data-ascii "{ \

}" --compressed "https://www.blackmagicdesign.com/api/register/us/download/16b195b1b9c54c0089aaa3ef0757a457" 

Its output is:

<body bgcolor="white">

<hr><center>openresty</center>

</html>

If I use a variable "foobar" to store it, the variable will be empty.

I guess this empty _srcurl cause this problem.
