[Bug c++/19281] New: file format not recognized; treating as linker script

[jeff at connectrf dot com]

Compile seems to work fine but will not link.  Any thoughts?

This is not a gcc bug, either this is your bug and the .o file is not an object file or this is a binutils bug.

Andrew, then perhaps you can explain why the exact same code compiles, links and
runs fine in a Microsoft environment?  So the only thing that has changed is I
am using GCC....  Hmmmmm..

But GCC is only the compiler, not the assembler and linker, report this to the binutils project, <http://
sourceware.org/bugzilla/> which controls both the assembler and the linker, yes this is confusing but 
correct.

Andrew,

A view from the ld folks.  They believe that the ld is failing due to the
-fpreprocessed switch not producing the .o file..

Subject: Re:  file format not recognized; treating as linker script

Hi Jeff,


>> I tried it with -c same result.  Also, when I ran file on it it says ASCII text.


Hmm, what size is the file ?


>> Here are the messages
>> 
>> **** Full rebuild of configuration Release for project Auth ****

Note - I would strongly suggest that you halt the build process after 
the creation of the first object file.  Things have definitely gone 
wrong by this point.  We are not looking at a linker bug, we are looking 
at a gcc bug or possibly a gas bug.

There appears to be something very odd going on when an object file is 
built:



>> g++ -O3 -Wall -c -fpreprocessed -M -v -oAuthTest.o ../AuthTest.cpp


So G++ is invoked on AuthTest.cpp.  I assume that the "-fpreprocessed" 
switch is correct and that this source file has already been pre-processed ?

... and yet GAS has not been invoked to turn the assembler output of the 
cc1plus.exe program into an object file.

Perhaps ... the g++ driver program is picking the wrong executable to 
use to convert assembler into binary ?

[Bug driver/19281] file format not recognized; treating as linker script

[pinskia at gcc dot gnu dot org]

Invalid, -M -o t, ouputs the depenciences in t.  So again this is not a bug in the compiler but in the 
makefile.

Andrew,

What compiler option flag do I need to set for forward Declartions then?  _M was
taking care of those errors however it is not producing the .o?  Is there a
Crossrefrence of compiler options between MC VC++ and GCC?

I have no idea what option you are talking about?
Look at the info/man pages of ld and gcc.

Andrew, let me try again.  BTW I have looked at the man pages for both gcc and
ld, I must say they are clear as mud, but then most are.

If I take the defaults, in CDT, I receive the errors attached below.  If I add
the options -fpreprocessed and -M as miscellaneous options, as I found in the
man pages,  the files compile without issue, but gcc does not create the proper
object files for linking.

So what gcc options would be required for forward declarations and standard
#include's?

Here is the makefile...

This is your bug and not gcc bug, figure out why you are getting the following error:
../AuthTest.h:7:10: #error include 'stdafx.h' before including this file for PCH

The reason why it works just fine for -M, well it does not fully compile, it only emits the dependencies.

Andrew,

If I take the exact same code, and compile it with VC++ it does not complain! 
However, gcc the ONLY thing that has changed, will not compile code that works!

Why? Old wise one, must one rewrite entrie working applications just so gcc
understands??

../AuthTest.h:7:10: #error include 'stdafx.h' before including this file for PCH

See that error, in VC++ (which is not usually a compand line driven) you have a PCH which use, do "-
include stdafx.h" on the command for gcc since that is actually done for you with VC++, this is still not 
a gcc problem, please stop reopening this bug as it is not a gcc bug and cannot be.

Considering -M does not actually compile your code, no I am not hard to convince.
Read the manual for gcc and you will see -M does not compile the code at all, only gets the dependices 
for include files.

Jeff,

The problem does not have to be the source code or the compiler, it can be the
way that you are invoking the compiler.  I do not understand why you are
invoking the compiler with -M -fpreprocessed -- you say that with those options
it works, but it obviously does not work.  I infer that you mean it works
because you no longer receive error messages, but that change in behavior is a
byproduct of the option not because those options are necessary or correct.  You
are skipping the compiler processing that produces the error messages *and*
skipping the compiler processing that produces an object file.

David

Those additional options are wrong.  You need to figure out how to address the
error messages.  If the application source code is standard C++, it should
compile with both VC++ and with G++, modulo problems with conformance to standards.

As best I can figure out from the discussion thread, VC++ is being "friendly"
and implicitly inserting some header files that should be referenced explicitly.
 This is a difference in behavior between the two compilers, not a bug in either
one.  However, you need to adapt your source code and your build machinery to
the behavior of each compiler.

Well that makes sense..

Does anyone have an example of the compiler options to port from VC++ to GCC?  A
nice Crossreference table would be just dandy.

Well open a new bug for that and/or figure out what the options do, all of the gcc options are 
documented and if they are not, then that is a bug.
