Thanks for your help, but I am still not able to link curl header files in
oracle 11g setup. Able to create .c & .o files but not executable.
I am using AIX box. As per your suggestion linked to lib path where
libcurl.a exist.

Is there any other way to check if linking is working fine? just by
command? Is there difference between 32bit & 64bit libraries ? I am using
object mode=64 when compiling.

$MY_ORA/bin/oraxlc -q64 -o fms_uploader fms_uploader.o -L$ORA_PATH /lib/
-lm -lld -L/lib -lm -lld -L$LIB_PATH_CURL -lm -lld -lclntsh
-L/lib/libcurl.a -lm -lld -L/lib/libcurl.la -lld -lm `cat $ORA_PATH
/lib/sysliblist` -lm -lc_r -lpthreads -lm -lcurl

Error:
