-Dusethreads \

The Perl configure command produces this error:

I used the command:

        cc_r -o try -O -D_ALL_SOURCE -D_ANSI_C_SOURCE -D_POSIX_SOURCE -qmaxmem=-1 -qnoansialias -qlanglvl=extc99 -DUSE_NATIVE_DLOPEN -DNEED_PTHREAD_INIT -I/usr/local/include -brtl -bdynamic -L/usr/local/lib try.c -lpthread -lbind -lnsl -ldbm -ldb -ldl -lld -lm -lcrypt -lpthreads -lc
         ./try

and I got the following output:

ld: 0711-738 ERROR: Input file /usr/lib/libdb.so:
        XCOFF32 object files are not allowed in 64-bit mode.
I can't compile the test program.
(The supplied flags or libraries might be incorrect.)

You have a BIG problem.  Shall I abort Configure [y]
Ok.  Stopping Configure.

64 bit library is available in /usr/lib64 or /opt/freeware/lib64 . You can include -L/usr/lib64 in your LDFLAGS to avoid this build error.

I tried this and got the same error:

export LDFLAGS="-L/opt/freeware/lib64 -L/opt/freeware/lib -L/usr/local/lib -Wl,-blibpath:/opt/freeware/lib64:/opt/freeware/lib:/usr/local/lib:/usr/lib:/lib -Wl,-bmaxdata:0x80000000"

Here is what is in /opt/freeware/lib64 for libdb.*  There is no libdb.so

Make sure you use AIX linker and not GNU binutils linker. 

export AR="/usr/bin/ar"

export LD="/usr/bin/ld"

Have a look at AIX Toolbox perl spec file for proper build parameters --> ftp://public.dhe.ibm.com/aix/freeSoftware/aixtoolbox/SPECS/perl-5.22.0-1.spec

I took a look at the link you supplied and changed my build environment to be the following:

export CC='/opt/IBM/xlC/13.1.3/bin/xlc_r -q64'
export LDFLAGS="-s -Wl,-bmaxdata:0x80000000 -L/opt/freeware/lib64 -L/usr/lib64 -L/opt/freeware/lib"
export AR="/usr/bin/ar"
export LD="/usr/bin/ld"
export OBJECT_MODE=64

Unfortunately I get the same error.

ld: 0711-738 ERROR: Input file /usr/lib/libdb.so:
        XCOFF32 object files are not allowed in 64-bit mode.

Don't use -bmaxdata flag for 64bit compilation. This flag is only useful in 32bit compilation and can have negative effect for 64bit compilation.

But this is not related to your error.

I just did a build of perl 5.26.1. It is successful. Not sure what is the problem in your setup. 

export AR="/usr/bin/ar"
export LD="/usr/bin/ld"

make

Do you also have db-4.8.24-3.aix6.1.ppc.rpm installed?

Originally posted by: AyappanP

Yes. I also have db-4.8.24-3 installed. Checking this perl library DB_File.so. It's perfectly linking with the 64bit libdb library.

# ldd ./lib/auto/DB_File/DB_File.so
./lib/auto/DB_File/DB_File.so needs:
         /opt/freeware/lib64/libdb.a(libdb-4.8.so)
         /usr/lib/libpthread.a(shr_xpg5_64.o)
         /usr/lib/libc.a(shr_64.o)
         /unix
         /usr/lib/libcrypt.a(shr_64.o)

And yes , we should not be using -bmaxdata for 64 bit compilation.
