Apache start error on SAP Content server 6.40

[Former Member]

Hi all

I installed a SAP Content Server 6.4 successfully in Solaris 10 with MaxDB 7.6.

Although Installation is finished completely I got an syxtext error when apache web server is started after completing installation as below;

dmscs/bin>./apachectl start

Cannot load /usr/sap/XXD/apache/libexec/mod_sapcs.so into server: ld.so.1: httpd: fatal:sap/Apache/libexec/mod_sapcs.so: wrong ELF class: ELFCLASS64

./apachectl start: httpd could not be started

let me know to solution if you had experienced with the same problem.

Hi,

When you compiled Apache did you set the compile switch variable CFLAGS="-xarch=v9" as per Note 664384 - Generation info for Apache Web server for SAP Content Server ?

Hi Nelis,

We set the CFLAG as per the SAP Note but it give CFLAG doesn't exist.

It's CFLAGS not CFLAG.

From what I can see it looks like you have compiled Apache with 32bit libraries and the sapcs module is 64bit which is why you are getting that error. You need to set the CFLAGS correctly so it gets compiled with 64bit libraries.

HI Nelis,

We set the CFLAGS correctly but when compiling we are getting the error below:

gcc -m64 -c -I../os/unix -I../include -DSOLARIS2=2100 -DUSE_HSREGEX `../apaci` gen_test_char.c

gcc -m64 -DSOLARIS2=2100 -DUSE_HSREGEX `../apaci` -o gen_test_char gen_test_char.o -lsocket -lnsl -lpthread -lexpat

Hmm, been a while since I worked on Solaris

ld.so.1: gen_test_char: fatal: /usr/sfw/lib/libexpat.so.1: wrong ELF class: ELFCLASS32

Basically you need to make sure the compiler see's your 64bit libraries so do you have a /usr/sfw/lib/amd64 directory by any chance ?

If so, try export the variable LDFLAGS="-L/usr/sfw/lib/amd64 -R/usr/sfw/lib/amd64" and compile again(with same CFLAGS).

Hi Nelis,

we got another error, grateful if you can have a look on this;

The export variable used are below:

Thanks for the response

gcc: language arch=v9 not recognized

Try using CFLAGS="-m64" instead of CFLAGS="-xarch=v9"

Hi Nelis,

its work fine... indeed thanx.

Good to hear.

SAP must update Note 664384 so that it includes CFLAGS="-m64" for newer releases of Solaris 64bit.

Hi Nelis,

I can access the Apache URL but not the SAP Content Server.

They was no "ContentServer/ContentServer.dll" directory exist under the apache/htdocs.

Can u help me where I did the wrong?

Panu

You should read the Unix installation guide. At the end of the guide in the Appendix there is a section for module registration and configuration if you are using Apache 1.3 - you must follow the instructions. I used Apache 2.x so never came across this issue.

You need to change your httpd.conf to point to the correct location for contentserver.dll and the directory structure must be setup correctly.

Hi Nelis,

We did the module registration after after installation, Please find the below of httpd.conf.
