make not create .so in aix7.1 and httpd 2.2.14

[jginer]

We need to create the modules .so in aix 7.1 and httpd 2.2.14

We follow instructions of the documentation:

Download the mod_cluster sources: mod_cluster.1.1.3.Final-src-ssl.tar.gz

Build the mod_cluster modules components, for each subdirectory advertise, mod_manager, mod_proxy_cluster and mod_slotmem. We do:

sh buildconf
     Creating configure

./configure --with-apxs=/usr/IBMAHS/bin/apxs
     checking for Apache httpd installation... APXS is /usr/IBMAHS/bin/apxs
     apxs support is true
     configure: creating ./config.status
     config.status:creating Makefile
     
make 
     /usr/IBMAHS/build/libtool --silet --mode=link xlC -g -qHALT=E -Wl,-brtl -L/usr/include/openssl/lib -Wl,-brtl -L /usr/include/openssl/lib -lm -p mod_advertise.la -rpath /usr/IBMAHS/modules
     -module -avoid-version mod_advertise.lo
     libtool: link: unable to infer tagged configuration
     libtool: link: specidy a tag with '--tag'
     make: 1254-004 The error code from the last command is 1.

Can someone help me?

It looks like the libtool you have is broken, where did you get the Apache httpd?

I guess libtool can't find the C compiler may be -tag=CC could help.

What does apxs -q CC says? Do you have the same compiler?

[jginer]

It is the Apache distribution for IBM AIX compiles and distributes 'Expansion Pack'

Apache HTTP Server 2.2.14.0 httpd.base

[jfclere]

Ok (I was hoping you compile it your self) :-(

So What does apxs -q CC says? Do you have the same compiler?

[jginer]

(/usr/IBMAHS/bin)# ./apxs -q CC
xlC
(/usr/IBMAHS/bin)# xlC -qversion
ksh: xlC:  not found.
(/usr/IBMAHS/bin)# lslpp -l|grep xlC
  xlC.aix61.rte             12.1.0.0  COMMITTED  IBM XL C++ Runtime for AIX 6.1

  xlC.sup.aix50.rte          9.0.0.1  COMMITTED  XL C/C++ Runtime for AIX 5.2

Does mean that the compiler is not installed?

[jfclere]

Yes that seems to the problem.

[jginer]

Can we use another compiler (gcc)? How?

[jfclere]

Using gcc isn't a good idea you have to use the same compiler for httpd and mod_cluster otherwise it won't work.

[jginer]

We install xlc:

xlc -qversion

IBM XL C/C++ for AIX, V12.1 (5765-J02, 5725-C72)

Version: 12.01.0000.0000

We repeat instructions of the documentation for each module (proxy, slotmem, manager, proxy_cluster), and only advertise was erroneous:

sh buildconf

     Creating configure

./configure --with-apxs=/usr/IBMAHS/bin/apxs

     checking for Apache httpd installation... APXS is /usr/IBMAHS/bin/apxs

     apxs support is true

     configure: creating ./config.status

     config.status:creating Makefile

make

ld: 0711-244 ERROR: No csects or exported symbols have been saved.

make: 1254-004 The error code from the last command is 8.

Stop.

Any suggestion?

[jfclere]

The only difference in the makefile is that advertise has only a single source file... Weird :-(

Would it be possible to run:

/usr/IBMAHS/build/libtool with --debug to see what failed in the build.

[jginer]

Hi,

One week later, we try it again and the archive .so is created.

We only do a "make clean" before to repeat the instructions.

Thank you for your help.

Regards,
