Link error

[Vardhan, Sundara (GE Infra, Energy)]

Hi All
 
I compiled successully gcc 4.2.3 version on AIX 5.3. Using g++ and AIX ld, I get the following error :
 
ld: 0711-562 SEVERE ERROR: Symbol table entry 734 in object sample.a
An auxiliary symbol table entry is required for a C_EXT or C_HIDEXT entry.

Any ideas what this is and how this can be fixed? I would very much appreciate your inputs and advice.
 
With Regards
 
Vardhan

You have to provide sbrk.

Hi gcc experts,

I try to compile a sample .c file that communicates with the GPIB 
interface (see attached c file) by using
GCC type of compilers, such as cygwin, Dev-Cpp, MinGW, and C-Free4. Then 
I got the same sort
of error messages - the low level drivers were not found, see the log below:

gcc.exe "C:\Program Files\Agilent\IO Libraries 
Suite\ProgrammingSamples\C\VISA\idn.c" -o "C:\Program Files\Agilent\IO

The low level drivers, such as viPrintf and viScanf  are in the file of 
visa32.lib that is seated in the directory of ...\lib\msc.
I mean the drivers are sit there but he compiler complains that the 
drivers were not found. And the same error happens
either in windows application or in DOS window. Is there something 
wrong? Please advise. What I expect is to produce
an .exe file that will talk to the instrument that is connected with the 
pc with a GPIB interface.

The linker complains, that in the files you are linken, the functions
viPrintf,... are used but never defined. 
> The low level drivers, such as viPrintf and viScanf  are in the file of

The Problem is: You have to tell the compiler to use the file
visa32.lib!
Try the additional parameter "-lvisa32" (telling gcc to link to a
library "visa32" - gcc will search in the Library-Directory which you
already specified). However, never having used gcc in Windows, I'm not
sure wheter gcc will recognize visa32.lib, when you link to visa32.

If not, try to give the complete Path to visa32.lib:
gcc.exe "C:\Program Files\Agilent\IO Libraries Suite\ProgrammingSamples\C\VISA\idn.c" -o "C:\Program Files\Agilent\IO Libraries Suite\ProgrammingSamples\C\VISA\idn.exe"   -ansi -I"C:\Program Files\VXIPNP\WINNT\include"   C:\Program Files\VXIPNP\WINNT\lib\msc\visa32.lib

Then, gcc will pass visa32.lib to the linker and your errors should
disappear

I doubt it's the makefile that's the problem...

BTW, I have gcc 4.1.0 running on AIX 5.3 and 6.1, and gcc 4.2.3 on 
6.1 and all work just fine for 99% of the pre-packaged things I've
found, and all of my custom apps (except for my own errors, of
course...). 

We're going to need a bit more information here.

Hi 

AIX is 5.3, gcc is 4.2.3 and ld is 2.18. Yes I downloaded the source and compiled it locally on AIX

We have a product running successfully on Solaris and AIX for many years and we have recently decided to port to Linux. This was done successfully. Since we used gcc on Linux, we decided to go with gcc on all the OS platforms we support. Towards this goal, I downloaded gcc 4.2.3 on AIX and Solaris. Compiled on AIX and installed it successfully. When I tried to use this gcc to compile the product code, the below error occurs only in couple of places.

What does this error mean?

Do you want me to send the compile/load line?

Thanks for your help.

With Regards

Hi Andrew

I checked libc.a using nm and .__memmove is defined. The following is the compile/load line where it fails

gcc -W1,-soname=x.so -o x.so .*I6.o -shared   -Wall -D__USE_GNU -D_GNU_SOURCE -DDEBUG -DLEAVE_OUT_REV_ID -O2 -D_ALL_SOURCE -Drs6000  -D__EXTENSIONS__ -I/usr/openwin/include -DAIX53 -U__MATH__ -DAIX  -DRS6000 -fPIC -L<libpath> -lsbI6 -L<libpath> -ldbI6
/lib/libc.a(moveeq.o):moveeq.s:(.pr+0xc): undefined reference to `.___memmove'

I think as you have suggested, I may have compiled and installed gcc incorrectly.

Hope this helps. Thanks much for your help.

Ouch.  You're linking statically against libc.  I don't know what's
causing this, but I suspect it's a Bad Thing.

/lib/libc.a typically is/contains a shared object on AIX.
Yes, AIX is confusing.

You might consider using automake and libtool, which takes care of all
this for you.

.so is not the universal extension for shared libraries.  Under windows
(and Cygwin) it's .dll, under darwin it's .dylib, and so on.  You really
shouldn't hardcode this information and expect to have a portable
makefile.

Under Cygwin the normal convention is that for a library named "foo" the
shared library is cygfoo.dll and the import libray is libfoo.dll.a.  If
it is a versioned library then it is cygfoo-n.dll and libfoo-n.dll.a.

Under Cygwin, when you specify -lxyDEVS, the linker will search for the
following filenames (in this order):

libxyDEVS.dll.a
xyDEVS.dll.a
libxyDEVS.a
cygxyDEVS.dll
libxyDEVS.dll
xyDEVS.dll

(As documented at
<http://sourceware.org/binutils/docs-2.16/ld/WIN32.html#WIN32>.)

So of course it errors because .so is not tne correct extension under
Cygwin.  You can still link against a .so file but you will probably
have to specify its full filename like with other link objects, as
opposed to -lfoo.

Link Error

[Tom Browder]

I compile a program on host A (Linux, i386) with g++-3.1.1.  I copy it
to machine B and attempt to execute it and get the following message:

makebar: /usr/local/lib/libstdc++.so.4: no version information available
required by makebar)

I recompile the same program on host B (Linux, i386) with g++-3.1.1 and
it works fine.

What is happening, please?

Thanks.

Very helpful! Any way to tell what shared libs and how to correct it?
And what does the message about needing a version mean?

Thanks.

Install exactly the same gcc/g++ environment on both machines.
OR
Try static linking.

Hi,

I tried to build the gcc-2.95.2 using the --with-newlib option, because I
got the __eprintf unresolved external on trying to link the library with CC
that I previously build with gcc.

I read that if I rebuild my gcc with --with-newlib option that would
illuminate  __eprintf problem.

That's exactly what I did except I got the same unresolved external trying
to build gcc

Here is the error

../stage1/xgcc -B../stage1/ -B/usr/local/sparc-sun-solaris2.7/bin/ -DIN_GCC

Any suggestions?
