ld doesn't work with 64bit support in aCC 3.30 when SDKROOT set

Chanthu Nair — Mon, 04 Jun 2007 01:33:05 GMT

ld command exit with status 1 when SDKROOT set for 64 bit support in aCC 3.30 and not display any error message.

env | grep SDKROOT
SDKROOT=/opt/aCC.03.30
[77] % ld -b +s -o libicui18n.sl.18.1 ucnv_cnv.o
[78] % echo $status
1
Any idea about this kind of issue ?

To set up a SDK you must have ALL of the tools under /opt/aCC.03.30/:
http://h21007.www2.hp.com/dspp/tech/tech_TechDocumentDetailPage_IDX/1,1701,2548,00.html

If you just want to use floating installation for aC++, you can just invoke:
/opt/aCC.03.30/opt/aCC/bin/aCC

All tools present under /opt/aCC.03.30

# cd /opt/aCC.03.30
# ls
opt usr
# cd opt
# ls
aCC ansic langtools
# cd a
# cd aCC
# ls
bin include include_std lbin lib
# pwd
/opt/aCC.03.30/opt/aCC
# cd /opt/aCC.03.30/usr
# ls
ccs include lib
# cd ccs
# ls
bin lbin lbin_bak lib

Is it correct or not ?

I take it you have the WHOLE directory tree (or symlinks) for /usr/include/, /usr/lib/ and /usr/ccs/ under /opt/aCC.03.30/usr/?

You'll also have to have your libs and includes there and set TARGETROOT.

You should add -v to ld to see where it goes wrong. (Any reason you are using ld directly to build a shlib, instead of a driver?)

Re: ld doesn't work with 64bit support in aCC 3.30 when SDKROOT set

Chanthu Nair — Mon, 04 Jun 2007 04:45:32 GMT

TARGETROOT is already set.
I tried with ld -a option, but no luck.
I think it cannot invoke the ld command itself.
The same sttings works fine for 32 bit.

The problem is that the ld cannot redirect to
/opt/aCC.03.30/usr/ccs/lbin/ld64.

Any Idea about how can I explicitly call ld64 through ld coomand.

Why -a? What happens with -v or -t?

>The problem is that the ld cannot redirect to /opt/aCC.03.30/usr/ccs/lbin/ld64.

That should happen automatically if ucnv_cnv.o is a 64 bit ELF file.

>Any idea about how can I explicitly call ld64 through ld command.

That is a contradiction in term. :-) To explicitly invoke ld64, you must do it yourself. As I said before try invoking the driver to create your shlib:
$ cc +DD64 -b -Wl,+s -o libicui18n.sl.18.1 ucnv_cnv.o

Have you set NLSPATH, to the wrong place?

Re: ld doesn't work with 64bit support in aCC 3.30 when SDKROOT set

[56] % cc +DD64 -b -Wl,+s -o libicui18n.sl.18.1 ucnv_cnv.o
[57] % echo $status
1

this driver usage is also not working.

[54] % ld -v -b +s -o libicuuc.sl.18.1 ucnv_cnv.o
[55] % echo $status
1

even -v option doesn,t give any message

The foolowing is the exicution of a 32 bit objct file

[64] % ld -v -b +s -o libicuuc.sl.18.1 ucnvscsu.o

I see no evidence of SDK support until A.03.37.

I have three installation of aCC. aCC 3.70, aCC 3.57 and aCC 3.30.

aCC 3.70 as my default installation.

If SDKROOT doesn't support, then how can I use aCC 3.30 installation.

>If SDKROOT doesn't support, then how can I use aCC 3.30 installation?

The problem is in ld, not the compiler. You simply use the latest linker in all cases. Or a new enough ld that supports SDKROOT.

And A.03.30 does support floating installation.

You might want to use "tusc -fp -o tusc.out ld ..." to help you figure out why ld is getting an error but not printing any messages.

Re: ld doesn't work with 64bit support in aCC 3.30 when SDKROOT set

Chanthu Nair — Tue, 05 Jun 2007 01:45:33 GMT

Attached here with the output of 'tusc -fp -o tusc.out ld -b +s -o libicuuc.sl.18.1 uresdata.o' for both aCC 3.30 64 bit and aCC 3.57 64 bit.

In aCC 3.57 it works fine, but in aCC 3.30 it recursivly call some commands and exit.

Could you please compare this two outputs ?

>but in aCC 3.30 it recursively call some commands and exit.

As I said, the ld you have in /opt/aCC.03.30 doesn't support SDKROOT. You'll have to stop using SDKROOT with that version. Or you'll have to copy a newer ld into that path.

After all, ld should be upward compatible.

Looking at tusc shows it going from /usr/ccs/bin/ld to /opt/aCC.03.30/usr/ccs/bin/ld to /usr/ccs/lbin/ld64 to /opt/aCC.03.30/usr/ccs/bin/ld ...
