I have successfully compiled and run a small application on SUSE 9.

I am now trying to compile it on SUSE 11.
Compile command is:
cc -m32 -O2 -I$CSW_HOME/cinc -DOS_UNX -D_CCODE -DDB_ORACLE -DOS_SUN -DOS_SUSE11
-o $1.EXE $filename `
cat $CSW_HOME/jobs/proc32.cmp` -lcurl -lcsigen -lcsigen2 -lcsidbo -lcsiunx
-lcsiingr -lingeurol -lingpri
nt -lsockunx -limo2000 -lingfrght -lingfedx -lingesms
Which gives:

Curl is installed on the system:
uschizlifa4004:/app/csw/jobs> rpm -qa | grep curl
curl-7.19.7-1.51.1
libcurl4-7.19.7-1.51.1
And libcurl.so exists
uschizlifa4004:/app/csw/jobs> ll /usr/lib64/*libcurl*
lrwxrwxrwx 1 root root 16 May 11 2016 /usr/lib64/libcurl.so.4 ->
libcurl.so.4.1.1
-rwxr-xr-x 1 root root 467504 Mar 23 2016 /usr/lib64/libcurl.so.4.1.1
I tried creating a link from the application object directory
uschizlifa4004:/app/csw/object> ll *libcurl*
lrwxrwxrwx 1 cswadm cswadm 27 Nov 28 08:34 libcurl.so ->
/usr/lib64/libcurl.so.4.1.1
But this gives the error:

"-m32" says "compile for 32 bits" but the libraries you are trying to
use are 64 bits ("/lib64", "x86_64"). You probably do not have the
32-bit libraries installed on the newer machine. If you install a
64-bit OS on your machine, you typically get only 64-bit libraries by
default and have to request 32-bit libraries explicitly. I don't use
SUSE on any of my machines so I can't tell you the package names to look
for, but they will typically be a variant of the 64-bit package names.
