Hi,
How can I retrieve the mandatory file setuid_drv, using CEAN ?

May be it’s possible to start yaws without ?
Thanks for your help…

this file is useless on windows,
I did not tested the whole thing, but I think a minimal service can run without that shared library.
it is actually provided for linux-x86 and darwin-powerpc
on other platforms, we need user contributions as I can not compile it.

if you can compile yaws on your system, you can send the .so to make your platform fully supported

all setuid_drv.so can be sent to: contrib (at) process-one (dot) net

This is a Linux box
My problem is that I can’t start yaws.
application:start(yaws)
fails
yaws:start()
fails

This is related to the not found setuid_drv…
:(

I must compile it ?
May be I can just remove the setuid_drv need, this driver is only used to bind lower port number ?

yaws archive should extract the following files
yaws-1.68/priv/
yaws-1.68/priv/linux-x86/
yaws-1.68/priv/linux-x86/lib/
yaws-1.68/priv/linux-x86/lib/setuid_drv.so

if it can not find setuid_drv then you should have a problem with your environment.
can you
  cd yaws-1.68/priv
  ln -s linux-x86/lib

and test again ?

The link is already there, but when I start yaws:
./start.sh

1> yaws:start().

=ERROR REPORT==== 17-Apr-2007::21:50:03 ===

Now If I correctly link where the setuid_drv.so is searched (in ebin/../priv (sic !))
rolphin@karoten:~/Desktop/Downloads/Erlang/erlang/lib/yaws-1.68/priv$ ls -l
lrwxrwxrwx 1 rolphin rolphin   27 2007-04-17 21:51 setuid_drv.so -> linux-x86/lib/setuid_drv.so

I restart yaws:
1> yaws:start().

=ERROR REPORT==== 17-Apr-2007::21:52:19 ===

“Driver compiled with incorrect version of erl_driver.h ...“

Are you sure that Yaws is correctly setup to work ? ;p

answer is no, i did not tested it. I should as yaws is a very important package.
problem for me is lack of time :(

first, yaws do not load setuid_drv the good way. yaws.erl must be patched
from:
  1750 load_setuid_drv() ->
  1751   Path = filename:dirname(code:which(?MODULE)) ++ “/../priv/“,
to:
  1750 load_setuid_drv() ->
  1751   Path = filename:join(code:priv_dir(?MODULE),“lib”),
this is a much more convenient way to load driver.

second, i build it using R11B-2, erl_driver.h may have changed ? I should consider built id with R11B-4…

Can I try to retrieve the new version ?
Having yaws working properly can really boost CEAN adoption… :p

Remember easyphp on windows ? The bad side is that kiddies will start using it, but unfortunately critical bugs will be harder to find
CLYME (Cean Linux Yaws Mnesia Erlang) :p ?

a working version of Yaws will be available on Monday
from now, Yaws will be actively tested before each new release.

Excellent news !

French elections wasn’t so good :/

ok, i patched actual yaws to make it work
i have another problem
2> yaws:start().

=ERROR REPORT==== 23-Apr-2007::15:13:36 ===
Yaws: Bad conf: “Can’t find no config file “

we may define a default yaws.conf, allowing to serve a simple page into cean installation.
but if we want yaws:start to work, then yaws_config should be patched.
I think best is to define a default yaws script into bin directory of cean installation.

any thought ?

Humm, why not define some priv/etc/ directory ?
May be we want to keep the yaws.conf file outside of the yaws tree ?

Another point I’ve downloadedd the latest version of cean with the latest yaws and keeps having this problem :
Eshell V5.5.4 (abort with ^G)
1> yaws:start().

=ERROR REPORT==== 24-Apr-2007::14:13:44 ===
Failed to load setuid_drv (from “/home/rolphin/Work/Devel/Erlang/Cean/erlang/lib/yaws-1.68/priv/linux-x86/lib”) : “Driver compiled with incorrect version of erl_driver.h”{error,{shutdown,{yaws_app,start,[normal,[]]}}}
=ERROR REPORT==== 24-Apr-2007::14:13:44 ===
FATAL {‘EXIT’,normal}

I didn’t have to make the link myself which is a good point.
I’ve just created a ~/yaws.conf for testing purpose with nothing special.

So may be we can have cean:yaws not need the setuid_drv since anyone can bind port over 1024 ?
If we really need bind of 80 we can fall back to linux CAPABILITIES to permit a user to do it ...

I’ve read the code of setuid_drv, and it seems to do more thant just setting the user id :p
Removing it may be more difficult…

So to move forward I just need a useable Makefile for Linux to test some modifications on yaws.erl.
Do you think that’s possible to have a Makefile ?

http://yaws.hyber.org/download/yaws-1.68.tar.gz
it includes configure and generate Makefile

Thank you, is this the one you also use ?

yes, as you can see:
