YAWS not creating the directory structure on CentOS 5.8

Hi list,

I managed to install Yaws 1.92 from git (following the instructions from http://yaws.hyber.org/configuration.yaws) on CentOS 5.8 (final), x86_64 architecture, with Erlang/OTP R15B01, but I got few errors after building it. The errors were related to the path problems:
1. I started Yaws as root and it didn't create the CTL file because of non-existing a directory structure;
2. error in finding /usr/local/var/log/yaws (non-existing at the boot).
After I created manually these paths, I was able to start Yaws.

I write this message hoping it will help the other CentOS users.

Regards,
CGS

Do you happen to have the exact error messages you saw? If so please
send them to me.

I found that in the code, the return value of filelib:ensure_dir for
this directory was not checked or asserted. I changed the code to
check that it returns ok.

This is strange, as this directory is created under "make install"
using an install program appropriate for the platform, typically
"install -c -d" which is supposed to create any missing directories.
What do you get if you run

grep INSTALL include.mk

thanks,

Re: YAWS not creating the directory structure on CentOS 5.8

Hi Steve,

Here is the output (lines 76 and 77 from include.mk):

INSTALL=/usr/bin/install -c
INSTALL_DATA=${INSTALL} -m 644

As you can see, the -d option is missing. I have autoconf 2.68, if this info helps.

Cheers,
CGS

Re: YAWS not creating the directory structure on CentOS 5.8

The -d option is supplied within the makefiles, at the points where
the install tool is used.

Re: YAWS not creating the directory structure on CentOS 5.8

I really don't know what happened during the installation because I found in scripts/INSTALL (line 22):

install -d ${destdir}${vardir}/log/yaws

which should have been processed. I also test install -d separately and it works fine on that OS. Strangely enough, I suppose that will remain a mystery for the moment and, who knows, maybe this is an isolated case. Maybe it wouldn't be a bad idea to check if all the directory structure was completed before exiting from the installation part.

Cheers,
CGS
