Make command help. Exe are not created in right size

vaish — Tue, 04 Nov 2008 08:16:56 GMT

Hi,
I am new to makefile and make commands. I need to support an project. But When I execute make command , it is not creating the executables in right size.

It have created message_generator executable with size 19898480 bytes. But when I run the make command it is giving me only 2732176 bytes message_generator exe.

What are the things that I need to check or configure to run this make command correctly ?
Thanks In Advance
Vaish

Why are you looking at the size? Instead try to run the executable and see if it works.

One reason for a size bloat would be debug info, -g.

The executable is not working as expected.

I doubt whether it links with the necessary library files. How to check them ?

Thanks

And executable that is 1/8 the size probably wouldn't even work at all.

You can list shlibs with ldd(1):
ldd message_generator

Thanks Dennis Handly for telling me ldd command.

I really see the difference between old exe saved on precaution and the new exe created now

When I do ldd with old exe, it shows
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/lib/libdld.2 => /usr/lib/libdld.2
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/local/appl/gcc-3.4.2/lib/libgcc_s.sl => /usr/local/appl/gcc-3.4.2/lib/libgcc_s.sl
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/lib/libm.2 => /usr/lib/libm.2
/usr/local/appl/gcc-3.4.2/lib/libstdc++.sl.6 => /usr/local/appl/gcc-3.4.2/lib/libstdc++.sl.6
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/log/ccase/gcc-3.4.2-objdir/gcc/libgcc_s.sl => /usr/local/appl/gcc/lib/libgcc_s.sl
/usr/lib/libm.2 => /usr/lib/libm.2

But when I do the same with new exe , it shows
/usr/lib/libdld.2 => /usr/lib/libdld.2
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/lib/libdld.2 => /usr/lib/libdld.2
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/lib/libcl.2 => /usr/lib/libcl.2
/usr/lib/libisamstub.1 => /usr/lib/libisamstub.1
/usr/lib/libdld.2 => /usr/lib/libdld.2
/usr/lib/libm.2 => /usr/lib/libm.2
/usr/lib/libCsup_v2.2 => /usr/lib/libCsup_v2.2
/usr/lib/libstd_v2.2 => /usr/lib/libstd_v2.2

Is it possible for you to explain me what it is all about ?

This is using foreign devil g++.

This is using aC++ -AA.
It's unfortunate the latter isn't the one that works. :-(

Dennis,
I use CXX=/opt/aCC/bin/aCC and I compile in my Makefile. Do I need to make it to gCC compiler and compile them.

Thanks
Vaish

Is it possible for you to explain me "CXX=/opt/aCC/bin/aCC and CXXFLAGS=-AA -mt -c -g0 +objdebug -z -I$(BOOSTINCL) +W823 $(MK_CXXOPTS)" How should I modify them to point to gCC compiler ?

>I use CXX=/opt/aCC/bin/aCC and I compile in my Makefile. Do I need to make it to gCC compiler and compile them?

Well, my ulterior motive is to have you use aC++. :-)
But you could try setting CXX=g++.

>Is it possible for you to explain me "CXX=/opt/aCC/bin/aCC and CXXFLAGS=-AA -mt -c -g0 +objdebug -z -I$(BOOSTINCL) +W823 $(MK_CXXOPTS)"

This says use aCC to compile. And pass the -AA & -mt & -g0 & +objdebug +W823 ... options to it.

>How should I modify them to point to g++ compiler?

You need to point CXX to the absolute path of g++.
For CXXFLAGS, remove -AA -mt -g0 +objdebug +W823 and replace by -g -threads

Okay I modified as the following
CXX=gcc
CXXFLAGS=-g -I$(BOOSTINCL)

But I get errors like
/usr/ccs/bin/ld: Unsatisfied symbols:
std::basic_ostream >& std::operator<< , std::allocator >(std::basic_ostream >&, std::basic_string, std::allocator > const&)(first referenced in /var/tmp//cck6qFKn.o) (code)
std::basic_stringstream, std::allocator >::~basic_stringstream()(first referenced in /var/tmp//cck6qFKn.o) (code)
std::basic_istream >& std::ws >(std::basic_istream >&)(first referenced in /var/tmp//cck6qFKn.o) (code)

I hope I miss something else in CXXFlag to compile with gcc compiler

Re: Make command help. Exe are not created in right size

vaish — Tue, 04 Nov 2008 10:33:11 GMT

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

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++

#CXXFLAGS=-AA -mt -c -g0 +objdebug -z -I$(BOOSTINCL) +W823 $(MK_CXXOPTS)
CXXFLAGS=-threads -g -I$(BOOSTINCL)

But I see the following error ...

Can you please help me to modify the CXXflag correctly ?

Dennis Handly — Wed, 05 Nov 2008 11:37:18 GMT

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.

Dennis Handly — Wed, 05 Nov 2008 23:25:20 GMT

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

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

Re: Make command help. Exe are not created in right size

vaish — Thu, 06 Nov 2008 09:06:06 GMT

/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.)
