Problem creating shared object with gcc on AIX 4.3.3

Problem creating shared object with gcc on AIX 4.3.3

Hi,

We have a problem regarding shared library using gcc on AIX 4.3.3.

The command used to create shared objects using gcc is "gcc -fPIC
-shared". If we use gcc on AIX with the same command we get the
following:-

$ make -f makefile
gcc -fPIC -I../include -shared -DXP_UNIX -o sample.so sample.c
cc1: warning: -fPIC ignored for AIX (all code is position independent)
ld: 0711-317 ERROR: Undefined symbol: .GetFirstRecipient
ld: 0711-317 ERROR: Undefined symbol: .GetRecipientAddress
ld: 0711-317 ERROR: Undefined symbol: .GetControlData
ld: 0711-317 ERROR: Undefined symbol: .FreeControlData
ld: 0711-317 ERROR: Undefined symbol: .AddRecipient
ld: 0711-317 ERROR: Undefined symbol: .GetMessageFile
ld: 0711-317 ERROR: Undefined symbol: .GetPostOfficePath
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more
information.
collect2: ld returned 8 exit status
make: *** [sample.so] Error 1

The copy of makefile is attached herewith.

Request assistance to resolve this problem on gcc with AIX. Thanks in
advance.
Regards,

Suresh

	Read the AIX online documentation about creating shared
libraries, including -berok and -G options to the AIX linker (accessed
through GCC using -Wl,-berok and -Wl,-G).

Hi,

Jens-Uwe Mager maintains a web page which has some of the
best documentation outside of IBM on the AIX linker:
http://www.han.de/~jum/aix/

This might help you learn about compiling shared libraries
on AIX.
