Re: Apache fails to start when mod_deflate is enabled (Apache Users)

Hi,

Probing further I see that mod_deflate is having some problems.. and zcalloc, zcfree etc.. which seem like related zlib. I may be wrong here. Your thoughts? 

bash-3.2# ldd -r /usr/local/apache2/modules/mod_deflate.so

libc.so.1 => /lib/64/libc.so.1

ld.so.1: lddstub: fatal: relocation error: R_AMD64_32: file /usr/local/apache2/modules/mod_deflate.so: symbol zcalloc: value 0xfffffd7fff343880 does not fit

ld.so.1: lddstub: fatal: relocation error: R_AMD64_32: file /usr/local/apache2/modules/mod_deflate.so: symbol zcfree: value 0xfffffd7fff3438e0 does not fit

Thanks,

Hi, 

	I am trying to get the details for the machine on which it was built. 

Meanwhile my concern is while the apache runs fine when mod_deflate is
 disabled. 
Has it got to do something with the libz on the machine? 

Hmm very possibly. I would run ldd against httpd binary and compare the lib versions of all the libs apache is linked to with the ones on the build machine, starting with libz.

Hi, 

This apache is compiled from source. It was compiled on another machine though. 

In that case both boxes have to be completely identical, same hardware and software structure. Was the other box maybe 32 bit machine?

This is what the file and ldd result in. (The libraries refered are present in /lib/64)

bash-3.2# file /usr/local/apache2/modules/mod_deflate.so
/usr/local/apache2/modules/mod_deflate.so:       ELF 64-bit LSB dynamic lib AMD64 Version 1 [SSE CMOV], dynamically linked, not stripped

bash-3.2#ldd usr/local/apache2/modules/mod_deflate.so
libc.so.1 =>     /lib/64/libc.so.1
libm.so.2 =>     /lib/64/libm.so.2

Hi, 

	On a solaris AMD64 bit machine the apache server fails to start when mod_deflate is enabled.

Following is the error that I see.

Any pointers whats wrong here. 

Appreciate your help!

Thanks,

First how did you install apache, using Solaris binary or compiled from source? Second, post the output of:

$ file /usr/local/apache2/modules/mod_deflate.so

$ ldd /usr/local/apache2/modules/mod_deflate.so
