Hi NG

I use AIX 5.3, GCC 4.2.2 and ld 1.65.2.4 (2/8/07).

I have a problem when linking some binaries which are part of our product.
I could reduce the problem to a hello-world program. I get the following
errors when linking my hello-world program with the libraries of our
product:

ld: 0711-783 WARNING: TOC overflow. TOC size: 955784 Maximum size: 65536
Extra instructions are being generated for each reference to a TOC
symbol if the symbol is in the TOC overflow area.

Address: 0x00009ca8; RLD type: R_RBR; RLD length: 26
collect2: ld returned 12 exit status


The g++ call looks like this:

g++ -o testprog -maix64 -Wl,-bbigtoc -Wl,-brtl
testprog.o -lLib1 -lLib2 -lLib3 -lodm -lc_r -lld -ldl -lstdc++ -lclntsh -lpthread
-lz -lm_r

Most of these libraries are unnecessary for this hello-world program and
when I leave them, I have no problems building my test program. E.g. when I
leave -lLib2 -lLib3 the no error occurs. So I suppose the error is in one
of these two libraries. Of course I need the libraries for the mentioned
binaries of our product, so I cannot solve the problem by leaving out these
libs.
I googled "ld: 0711-780" and found some results which didn't really help me.
I tried different compiler and linker options but no one solved the problem
(-mlongcall, infos got from -bnoquiet, ...).

1. Is this a known problem?
2. Does it have to do with the TOC overflow warning? (Please note that I
already link with -bbigtoc)
3. What does this error description mean and what is meant by "Symbol
..global constructors"? I don't understand it.

Let me know if you need some more info to be able to help.
Thanks in advance!

Regards, Chris

On AIX 4.x there is no limit for TOC size. You can use -bbigtoc flag
and get around MAX TOC size using regular ld/bind. You will still get
the WARNING: TOC overflow message. This warning is expected whenever
TOC overflow occurs and the -bbigtoc option is used.

So i would assume the same for AIX 5.3

Thanks for your answer.

This warning is not my problem. I posted it because I don't know whether it
is relevant or not for the error which occurs while linking.
Btw, I use the -bbigtoc option as mentioned in my first post.
