erlang.mk tutorial release build failure about erlang.mk HOT 4 OPEN

That one seems like a download failure from hex. The hex download code isn't the most solid right now but it might solve itself if you make distclean and try again. The release test cases are not failing for me.

from erlang.mk.

git works fine behind the firewall with proxy setup, but hex doesn't seem to function properly.
Once I am on public internet, I am able to build and boot the whole release after couple of "make distclean".
By the way, werl.exe is removed from the OTP26 and "make run" has this error:
system cannot find the file C:\temp\erlang\hello_rel_rel\hello_rel_release\erts-14.0\bin\werl.exe.

Fixed by: ln -s erl.exe werl.exe and system is booting up.

This issue can be closed.

from erlang.mk.

Right in that case you need to configure curl proxy information for hex to work properly, see https://everything.curl.dev/usingcurl/proxies/env

Perhaps this can be documented.

About werl.exe please open a separate issue as something will have to be done about that.

from erlang.mk.

I configure curl proxy in Windows environment setting and both git and hex are working properly behind th firewall.
