Make command help. Exe are not created in right size

[vaish]

I tried with : CXXFLAGS=-g -z -I$(BOOSTINCL) -threads also

Getting errors like
gcc: unrecognized option `-threads'
/usr/ccs/bin/ld: Unsatisfied symbols: ....

If possible , help me please

Thanks

>CXX=gcc
>ld: Unsatisfied symbols:

This is the C compiler. You need: CXX=g++

>gcc: unrecognized option `-threads'

Oops, my man page was broken. All other OS versions showed -pthread vs -thread.

Dennis,
I have changed to g++ in my make file as the following ...
CXX=/usr/local/appl/gcc-3.4.2/bin/g++
CC=/usr/local/appl/gcc-3.4.2/bin/g++
#CXXFLAGS=-AA -mt -c -g0 +objdebug -z -I$(BOOSTINCL) +W823 $(MK_CXXOPTS)
CXXFLAGS=-threads -g -I$(BOOSTINCL)

But I see the following error ...
$mymachine: mk
$::ENV{'MK_ROOT'} = "/vobs/source"
$::ENV{'SHAREVOB'} = "/vobs/share"

Can you please help me to modify the CXXflag correctly ?

Thanks
Vaish

[Dennis Handly]

CXXFLAGS=-threads -g -I$(BOOSTINCL)

As I mentioned before, change -threads to -pthread.

>Can you please help me to modify the CXXFLAGS correctly?

I don't think the above change will fix these unsats? If it doesn't, have you forgotten to recompile everything with g++? The mangling is different between the two PA compilers.

CC=/usr/local/appl/gcc-3.4.2/bin/g++

The C command should be gcc, not g++
(Not sure this is the issue.)

[vaish]

/usr/ccs/bin/ld: Unsatisfied symbols is still there after modifying thread to -pthread and also to gcc.

The code is not compiled. It throws the same error.

Hi,

you try to compile and link his single file ap_format.C

Does it really contain all of the functions/classes like
FormatMessage::
Fcif::
p1Daemon::

I assume you need to compile + link more than this single file:
- you need an application library to link against
- you need to compile more .C files


I don't think, this current problem is a problem of the linker but a problem of the deps of this piece of SW.

(Skip the first part, I think Peter has the solution.)

>The code is not compiled. It throws the same error.

You have several choices depending on your skill levels:
1) Go back to aC++, that links. Get out your debugger and find out why isn't working as expected.

2) Spend weeks going though the C++ sources to figure out where symbols used in ccHNXrSE.o are defined.

Note: After solving 2), you still may get the isn't working as expected issue??

3) You could use aC++ to find where those functions are defined and used. And see why that isn't the case for g++.

If you can attach the aC++ ccHNXrSE.o, I can look at it.
Also, the next step would be to compile that .C with aCC and add "-E -.i" and attach ccHNXrSE.i.

>Peter: I don't think, this current problem is a problem of the linker but a problem of the deps of this piece of SW.

You are absolutely right. The "-c" shouldn't have been removed from CXXFLAGS.

(Of course this is broken. The -c should be in the build rules, not the flags.)
