compilation error of lsyncd2.beta1 about lsyncd HOT 28 CLOSED

Hi!

first configuring with --with-runner=/usr/local/share/ will workaround this 
problem, as in that case the part of Lsyncd written in Lua will be placed as 
text file there instead of compiling it into the binary - which causes the 
problem here.

For fixing this, can you please post the results of these commands in your 
lsyncd directory?

gcc -dumpmachine 

objdump -f lsyncd.o | grep architecture

objdump -f lsyncd.o | grep architecture | sed -e "s/,.*$$//" -e "s/[^ ]* 
\(.*\)/\1/"

cat architecture

okay, i found one issue with the architecture and fixed it in svn for a start.

thanks a lot but it failed again : architecture is empty (any dependency 
missing ?)

Marc

rm architecture and try again. looking through the rest right now. 

[deleted comment]

the problem is another tough, --output-target is in my case "i486-linux-gnu" 
which identical to the output of gcc -dumpversion ... dunno why redhat put 
anything "redhat in there".

okay, i fixed the target determination, can you please svn update, and try 
again?

i tried the r373 release.
so  :
./autogen OK
./configure OK
.make KO

so translating lsyncd.lua into an object format worked now :-)

strange missing dependency, and configure getting you the wrong math library.

Maybe libltdl defines these references for you?

:-) i did't solve the probleme

same problem with lua compiled or in binary package (5.1.4)

every thing seem's ok 

Is redhat 5.3 too old (libc 2.5?)

# ldd /usr/lib64/liblua.so
        libc.so.6 => /lib64/libc.so.6 (0x00002b123b339000)
        /lib64/ld-linux-x86-64.so.2 (0x0000003639400000)
# ls -la /lib64/ld-linux-x86-64.so.2
lrwxrwxrwx 1 root root 9 Oct  8 15:50 /lib64/ld-linux-x86-64.so.2 -> ld-2.5.so
# ls -la /lib64/libc.so.6
lrwxrwxrwx 1 root root 11 Oct  8 15:50 /lib64/libc.so.6 -> libc-2.5.so


more help needed ...

thanks a lot

Marc

still getting undefined reference to `dlopen'? 

Lsyncd actually doesnt reference it itself, it is referenced by Lua tough to 
dynmically load modules. Can you maybe ./configure && make stock lua-5.1 
yourself and post the logs? 

So, from a stock lua source (5.1.4) 

I compiled lua from /usr/src/lua5.1.4 directory.
all test are ok (lua and luac)

for exemple : (from test directory)
# lua env.lua
nil     root    
/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

cp /usr/src/lua-5.1.4/etc/lua.pc /usr/lib64/pkgconfig/

and modified 
configure.ac:PKG_CHECK_MODULES(LIBLUA, lua5.1)
to 
configure.ac:PKG_CHECK_MODULES(LIBLUA, lua)

because of error (pkg-config/lua5.1 not found)

i've forgot 

lsyncd2 sources version : r404 : last release today 

Marc

I suppose the automake variable $(LIBLUA_LIBS) is garbadged. The only reason 
why I can imagine make could think it would need to build "/usr/local/lib", in 
my case it is "-llua5.1" 

You can try following change in Makefile.am
--- replace ---
lsyncd: luac.o $(lsyncd_LDADD) 
--with--
lsyncd_LDADD += luac.o
----

IMHO thats better,

Sorry I'm still fighting with automake ;-)

ok. 

so with the last version (r407) it's working (yeah!)

with 
LIBLUA_LIBS = -L/usr/local/lib -llua -lm -ldl
instead of
LIBLUA_LIBS = -L/usr/local/lib -llua -lm
in the Makefile

Thanks a lot for this so interesting tool.

Best regards 

Marc

still remaining is the probleme :

yours sincerely
would you prefer an another channel for testing report ?


Marc

I fixed the lbash example hopefully for good :-)

About the manpage compilation, I dont know why it fails for you, manpages will 
be pre"compiled" on .tar.gz releases tough. 

I gladly accept your testing reports on any channel I can get! :-) Otherwise 
you might want to prefer the discussion group also.

BTW: Did you noticed how I advanced lua package detection? Should now work with 
several distro naming schemes.

Yes i noticed it. thanks you about your immediate reply. remaining is the 
'-ldl' option needed in the 'lua.pc' definition 

about manpage i found the problem. 
Add '--novalid' option to xsltproc line in "Makefile.am" . He will not try to 
load the dtd page.

so the line is :

doc/lsyncd.1: doc/lsyncd.1.xml
        xsltproc --novalid --nonet -o $@ /etc/asciidoc/docbook-xsl/manpage.xsl $<

in Makefile.am

Marc

i'm working from svn  ... that's why i didn't get the correct manpages...

Marc

as of r445, r448 failed in lbash.lua test .

:-(

yes, thats cool, since of course nothing thats being processed should go into 
the svn.

I changed Makefile.am so it correctly inherits the CFLAGS from configure, so in 
your case you could run:
CFLAGS=-ldl ./configure 

I'm just working on a MAC and I cannot get it to create the manpages either :-)

I was refering to comment 20, looking at the stuff.

Can you look at it again with latest version? 

so for r454

with 
CFLAGS=-ldl ./configure 
and 
Makefile.am : xsltproc --novalid --nonet -o doc/lsyncd.1 ...

autogen ......OK
./configure ..OK
make .........OK
make install .OK

lsyncd -log all -delay 1 /doc/lsyncd/lbash.lua.... OK :-))

Marc

Wayho! Looks like we are finally nearing the release. Actual content
in the manpage, maybe finishup fsevents and off it goes.

I'm closing this one, if you find new things please open a new issue :-)
