Help to compile C UDFs using gcc on AIX (bldrtn)

[PaulR]

Hi,

the following gcc compile/link (in bldrtn) works fine on our Linux
Servers

# Set the runtime path since routines run as setuid.
EXTRA_LFLAG="-Wl,-rpath,$DB2PATH/lib"

# If an embedded SQL program, precompile and bind it.
if [ -f $1".sqc" ]
then
./embprep $1 $2
fi

# Compile the program.
gcc $EXTRA_C_FLAGS -fpic -I$DB2PATH/include -c $1.c -D_REENTRANT

# Link the program and create a shared library
gcc $EXTRA_C_FLAGS -shared -o $1 $1.o $EXTRA_LFLAG -L$DB2PATH/lib -ldb2
-lpthread

However, when I try to use the same on our AIX Server (64bit on 5.3), I
get strange gcc errors on the Link

ld: 0706-012 The -p flag is not recognized.
ld: 0706-012 The -a flag is not recognized.
ld: 0706-012 The -t flag is not recognized.
ld: 0706-012 The -h flag is not recognized.
collect2: ld returned 255 exit status
cp: application_id: No such file or directory

If I leave off the $EXTRA_LFLAG, it compiles/Links fine, but gives
runtime errors so I guess it is needed ...

Anyone else have working gcc commands to use in bldrtn on AIX?
- the default bldrtn on AIX has commands for xlc_r and not gcc

Many thanks.

PaulR.

Jan,.

Thanks for that - Frustrating though it is, considering we only
need it for the userexits and a few UDFs.

Tested an UDF.

Only compiled with gcc (there are advices to use ld even when using gcc
as main compiler), linked with ld, ld is always part of the AIX
distribution.

ld -o myroutine myroutine.o -L$DB2PATH/lib -ldb2 -ldb2apie
-bE:myroutine.exp -e MYROUTINE1 -lc

Don't mind Jan. As long as you don't call him via 1-800-IBM what matters
is what works, not which compiler IBM supports ;-)

Thanks for the options.

I did try ld, it compiled fine but then gave some horrible run-time
error!

Anyway, we have got the project to cough up the £700 for xlc, and all
is working fine. (cheaper in the long run!)

Thanks again.
