The procedure entry point axiom_attribute_create could not be located in the dynamic link library
I have a project in c and I want to compile it in CodeBlocks with MinGW. I tried to link its needed libraries but I got
undefined reference error
so I searched and found out that the libraries that I was using was compiled with MVC++ and cannot be used with MinGW. (I am not an expert in c, so I'm a little bit confused.) I found This link and did what they said in order to solve my problem.
I have created axis2c .a files from the original axis2c .dll files.
- I created .def files with reimp
- then I modified each stdcall function in .def files (I changed "_name@ordinal" to "name")
- then I used dlltool to create .a files.
I linked the .a files to my project. Everything went fine and I could compile my project. but when I try to run it. I get this error.
The procedure entry point axiom_attribute_create could not be located in the dynamic link library
I have included my project in this Link.
I downloaded a CodeBlocks with MinGW. codeblocks-10.05mingw-setup.exe (which I guess uses MinGw32bit).Then I followed the steps that @mikekinghan said to set up Build Options. Then I built the project. I got this error. I have already added Axis2c lib folder to path Environment. (I even copied axiom.dll to "C:\Windows\SysWOW64" as @mikekinghan suggested.
Here is the build log :

It seems that I made a mistake putting ../include in Search Directories>Linker I fixed that mistake.
I build the project then I get this :

Form what @MikeKinghan tried to teach me, I understand the meaning of Linker commands now, and I see that the Linker is set correctly this time. but why can't it compile properly?
Your project contains 5 source files, which each has to be successfully compiled, and then all
need linked together, along with some axis2c DLLs, to build your program.
Let's look at your build log.
There is a compile command for each of the 5 source files:
mingw32-gcc.exe -Wall -g -IC:\Tools\axis2c\include -IE:\dev\CodeBlocks\MinGW -c E:\dev\c\Math\adb_addOperatorResponse.c -o obj\Debug\adb_addOperatorResponse.o
...
mingw32-gcc.exe -Wall -g -IC:\Tools\axis2c\include -IE:\dev\CodeBlocks\MinGW -c E:\dev\c\Math\axis2_extension_mapper.c -o obj\Debug\axis2_extension_mapper.o
...
mingw32-gcc.exe -Wall -g -IC:\Tools\axis2c\include -IE:\dev\CodeBlocks\MinGW -c E:\dev\c\Math\axis2_stub_MathService.c -o obj\Debug\axis2_stub_MathService.o
...
mingw32-gcc.exe -Wall -g -IC:\Tools\axis2c\include -IE:\dev\CodeBlocks\MinGW -c E:\dev\c\Math\main.c -o obj\Debug\main.o
...
mingw32-gcc.exe -Wall -g -IC:\Tools\axis2c\include -IE:\dev\CodeBlocks\MinGW -c E:\dev\c\Math\adb_addOperator.c -o obj\Debug\adb_addOperator.o
...
and then there is a link command:
mingw32-g++.exe -LC:\Tools\axis2c\include -LE:\dev\CodeBlocks\MinGW\lib -o bin\Debug\Math.exe obj\Debug\adb_addOperatorResponse.o obj\Debug\axis2_extension_mapper.o obj\Debug\axis2_stub_MathService.o obj\Debug\main.o obj\Debug\adb_addOperator.o -laxiom -laxutil -laxis2_engine -laxis2_parser
...
Copy/paste these commands out somewhere where you can see them from end to end.
In all of the places where I have put '...', the compiler or linker has emitted some complaint about your program.
All of the diagnostics emitted by the 5 compile commands are warnings. Whatever is not right, it doesn't actually stop the compiler from compiling the source
file (.c) into an object file (.o). If there had been any compilation errors in any .c file, then the compiler would not have been able to create the .o file,
and the build would have stopped without attempting to link the program, because linking it when some object files are missing would be futile.
This does not mean you don't have to bother about the compiler warnings. They might be warnings about possible bugs in your program, and some of them are. So you'll need to fix them.
The link command has failed. You have no program, which is your top problem.
In order to make sense of compiler and linker diagnostics, and be able to fix them yourself, you need to understand what the compiler and linker commands mean.
We can see that the toolchain Code::Blocks is driving for you is the MinGW project's 32-bit Windows port of GCC (The GNU Compiler Collection). GCC is the daddy of C/C++ programming toolchains: it's supported for every operating system and every processor; it's used in every application domain. It's completely independent of any of the numerous IDEs that you can get to drive it, and all of those IDEs (Eclipse, Code::Blocks, KDevelop, CodeLite, Anjuta, Dev-C++, etc.) come to you with the implicit assumption that you understand compiling and linking with GCC. At least, none of them can save you from having to understand compiling and linking with GCC.
Before going any further then, the life-lesson of all this is going to be: Kick away your IDE for a while. Learn about building programs with GCC, itself. Then it will be obvious how to do it with your IDE.
All of your compile commands are executed by mingw32-gcc.exe. That's the GCC tool-driver, in its C compiler "posture". If you look in the directory where it's installed,
maybe C:\MinGW\bin, you'll see also programs gcc.exe, g++.exe, plus those two with the prefix mingw32-. All of these programs
are the GCC tool driver, in different "postures" adapted to different roles.
Your link command is executed by mingw32-g++.exe. That's the GCC tool-driver again, in its C++ linker "posture". It may seem puzzling that Code::Blocks
by default configures the C++ linker to link C programs. It does that because C++ linkage works for programs that are all C, all C++, or a mixture of the two.
But C linkage won't work for C++ programs.
Whatever "posture" is suggested by the name, the GCC tool driver figures out what needs to be done by inspecting the options on its commandline and the file extensions
of the files that are passed to it. So it tries to compile each of your .c source files as C because they are .c files.
If they were .cpp files then it would try to compile them as C++. Once it figures out what it do, it delegates the work to an appropriate specialized tool -
C compiler, C++ compiler, assembler, linker.
Here's what each of your compile commands means:
-Wall=> Enable all warnings-g=> Generate debugging information in the object file.-IC:\Tools\axis2c\include=> Search for non-standard header files inC:\Tools\axis2c\include-IE:\dev\CodeBlocks\MinGW=> Also search for non-standard header files inE:\dev\CodeBlocks\MinGW-c=> Just compile; don't linkE:\dev\c\Math\some_filename.c=> Compile this file.-o obj\Debug\some_filename.o=> Output the object fileobj\Debug\some_filename.o
And here's what your link command means:
-LC:\Tools\axis2c\include=> Search for non-standard libraries (.lib,.a,.dll) inC:\Tools\axis2c\include-LE:\dev\CodeBlocks\MinGW\lib=> Also search for non-standard libraries inE:\dev\CodeBlocks\MinGW\lib-o bin\Debug\Math.exe=> Output the executablebin\Debug\Math.exeobj\Debug\adb_addOperatorResponse.o=> Link this object fileobj\Debug\axis2_extension_mapper.o=> Also link this object fileobj\Debug\axis2_stub_MathService.o=> Also link this object fileobj\Debug\main.o=> Also link this object fileobj\Debug\adb_addOperator.o=> Also link this object file-laxiom=> Link the libaryaxiom.dllor failing that,axiom.liborlibaxiom.a, wherever it is first found in the specified linker search directories (-L), or failing that in the linker's standard directories.-laxutil=> Link the libaryaxutil.dllor failing that,axutil.liborlibaxutil.a, etc...-laxis2_engine=> Link the libaryaxis2_engine.dllor failing that,axis2_engine.liborlibaxis2_engine.a, etc...-laxis2_parser=> Link the libaryaxis2_parser.dllor failing that,axis2_parser.liborlibaaxis2_parser.a, etc...
You might wonder how the tool-driver knows that the link command is a link command, and not perhaps a C++ compile command?
It knows there is no compiling to do because none of the input files can be compiled. They are all object files (.o).
And it knows it is supposed to link them because it hasn't been told not to link them: the -c option is absent.
You linkage failed because:
e:/dev/codeblocks/mingw/bin/../lib/gcc/mingw32/4.4.1/../../../../mingw32/bin/ld.exe: cannot find -laxiom
ld.exe is the linker itself: the specialized tool that the GCC tool driver invokes when there is linking to be done.
It can't find your axiom library in any of the linker search directories you specified (-L), nor, of course, in
any of the standard search directories.
Now that you understand the meaning of your link command, it will be easy for you to see what's wrong. The linker search directories that you specified are:
C:\Tools\axis2c\include
E:\dev\CodeBlocks\MinGW\lib
and your axis2c libraries (axiom.dll etc) aren't in either of those places. C:\Tools\axis2c\include
is the same place where you told the compiler to search for the axis2c header files: you have:
-IC:\Tools\axis2c\include
So if that's where the axis2c header files are, then the libraries, I guess, are in C:\Tools\axis2c\lib. Have a look.
Assuming that's right, then in the C::B IDE you need to delete the wrong C:\Tools\axis2c\include from Search directories -> Linker
for your project and replace it with the correct C:\Tools\axis2c\lib Leave C:\Tools\axis2c\include in Search directories -> Compiler,
because that is correct.
Continued for OP's further issues
I believe that your axis2c libraries and header files originated from Apache's Axis2/C download page
from the archive axis2c-bin-1.6.0-win32.zip.
This release suffers from a bug in its header files that causes the linkage errors you are seeing with the MinGW32 toolchain.
This bug does not affect Google's release of Axis2/C that I referred you to in my first answer to this question. At that time you said that you were building with 64-bit MinGW, but it has since become clear that you are building with 32-bit MinGW. In that case, you should download Google's 32-bit build Axis2/C
Unzip the archive with 7-Zip and rename the unzipped folder from axis2c to axis2c-x86-google, to make clear what it is, then copy it somewhere convenient
for your development. Let's say you put it at C:\Tools\axis2c-x86-google.
Then in the C::B IDE, in Search directories -> Compiler, change:
C:\Tools\axis2c\include
to:
C:\Tools\axis2c-x86-google\include\axis2-1.6.0
and in Search directories -> Linker, change:
C:\Tools\axis2c\lib
to:
C:\Tools\axis2c-x86-google\lib
The library that is called axiom.dll in the Apache release is called axis2_axiom.dll in Google's release. Therefore
in your Linker settings -> Other linker options, change:
-laxiom
to:
-laxis2_axiom
Your program then links successfully (for me).
Continued again
Per your comments, the program now fails to load at runtime with the error:
The procedure entry point axis2_callback_create could not be located in the dynamic link library
This means the correct DLL providing axis2_callback_create is not found at runtime.
You say:
I also added the "lib" to path environment. and also added the lib dll files to "C:\Windows\SysWOW64"
- Do one or the other, not both.
- Depending on what you did to add the Axis2/C library directory to the
PATH, it may have had no effect.- If you did this in a shell (command prompt) window that was not the very same one in which your tried to run your program, then it will have had no effect, since environment settings that you make in a shell apply only to processes launched in the same shell.
- If you did this by modifying the
PATHenvironment variable in Advanced System Settings then that will have no effect on a shell already open in which you tried to run your program. You would need save the Advanced System Settings and then try again to run your program in a new shell.
I am able to start your program without DLL errors in all of the following ways:
- With all of the files
C:\Tools\axis2c-x86-google\lib\*.dlllocated in the same directory withMath.exe - With all of the files
C:\Tools\axis2c-x86-google\lib\*.dlllocated instead inC:Windows\SysWOW64 - In a shell window in which I have previously run:
set PATH=%PATH%;C:\path\to\my\axis2c-x86-google\lib - In a new shell after I have added
C:\path\to\my\axis2c-x86-google\libto thePATHenvironment variable in Advanced System Settings.
If none of them works for you then I'm afraid the problem is beyond me :(
