Newbie question: Compiling helloworld-APR.c under Windows
Hello,
we are evaluating APR as a possible base for a multi-platform server
project.
I have successfully compiled and executed the following APR-"Hello
world!" program under Unix:
#include <stdio.h>
#include <apr_general.h>
int main(int argc, const char *argv[])
{
apr_status_t rv;
rv = apr_initialize();
printf( "Hello APR world!\n");
apr_terminate();
return 0;
}
Now I try to compile this with Visual Studio 8 (2005). I have
successfully built the APR libs and the test suite with Studio.
But when compiling the above program, I get the following error message:
------ Build started: Project: TestAPR, Configuration: Debug Win32 ------
Compiling...
try-helloworld-APR.c
d:\apr\apr\include\apr_errno.h(52) : error C2061: syntax error :
identifier 'apr_strerror'
d:\apr\apr\include\apr_errno.h(52) : error C2059: syntax error : ';'
d:\apr\apr\include\apr_errno.h(52) : error C2059: syntax error : 'type'
The respective line in apr_errno.c reads
APR_DECLARE(char *) apr_strerror(apr_status_t statcode, char *buf,
apr_size_t bufsize);
It seems that the macro APR_DECLARE is not defined.
I have spent one day to read all available documentation on APR and have
searched the mailing list archive for messages concerning how to compile
with APR under windows, but I just could not find out what settings I
have to specify to use the APR libs with Visual Studio.
The page http://apr.apache.org/compiling_win32.html just says
> Integrating the Library

> We should tell ya'll 'bout this, no?

Can you please help me? Any hints are highly appreciated.
Thank you and kind regards,
Joachim

I just want to tell you that some kind soul sent me the following
advices, which solved the problems for me:
> this should fix your problems:
>
> 1. Add ws2_32.lib and mswsock.lib to your depend libraries (fixes unresolved symbols)
> 2. Check the runtime library for APR/ApU and your project, they should be the same (e. g. multithread or multithread dll) (fixes multible symbols)
Now, what I still do not know, is: Should I have known this? Is there
some documentation missing or is it my missing experience with
development under Windows?
Thank you all,
Joachim

Posted by Joachim Ziegler <zi...@mpi-sb.mpg.de>.
Let me tell you exactly what I did.
I tried to follow as much as possible the information given on
http://apr.apache.org/compiling_win32.html
Again, I must admit that I have not used Visual Studio much in the past.
I come from a UNIX background. Maybe I do wrong something very basic.
I try to compile and link the following minimal program against the
static APR libraries within visual Studio 2005:
#include <apr.h>
#include <apr_general.h>
int main(int argc, const char *argv[])
{
apr_initialize();
apr_terminate();
return 0;
}
My installation of APR resides below D:\apr.
I created a new project APRTest in Visual Studio. On the properties
pages of this project, I entered:
- C/C++/General/Additional Include Directories:
D:\apr\apr\include;D:\apr\apr-util\include
- C/C++/Preprocessor/Preprocessor definitions:
WIN32
APR_DECLARE_STATIC
APU_DECLARE_STATIC
- Linker/Input/Additional dependencies:
D:\apr\apr\LibD\apr-1.lib
D:\apr\apr-util\LibD\aprutil-1.lib
Now I got the following error messages:

Sounds great - give me a day or two to freshen that document, and I'll
post when it's good to follow.
I'll be sure to add something about consuming libapr on win32 as well.

Good point - I missed that. Now the original email makes more sense.

You must mean libapr-1.lib/libapr-1.dll, yes, it is.
But no, it's not linked to apr-1.lib (static).
I'm contemplating some trickery which would ensure that the user doesn't
have to call out dependent libs, but not till apr 1.3.0

Sounds like the liker wants Winsock linked in (ws2_32.lib). Not sure
why your application wants it, as it should have been linked into
apr-1.dll already - maybe someone else can chime in.

Hello William,

I'm not quite sure to understand what you mean by this. Yes, I have
downloaded the win32-src.zip file and followed the instructions in the
section "Developer Studio Workspace/Microsoft Development Environment
IDE Build" on
http://apr.apache.org/compiling_win32.html
to build the libs.
I have also successfully built and run the apr/test/aprtest.dsw project.

Sorry, I do not understand what you say here. It might well be that I
just know too little about Windows programming in general. (I come from
a UNIX background.)

I have found out by myself that I have to declare this WIN32 macro by
following the compiler's error messages into the apr.h file. You say "of
course": Is this something I should have known beforehand because it is
customary in Windows development? If not so: I cannot read anything
about this in the official documentation!?
Anyway, now my helloworld compiles, but it does not link. I get the

If you used a -win32-src.zip file, and run nmake against the
makefile.win, you shouldn't be having problems.
If you import into VS2005/2008, there are dependency hassles,
but you can usually work those out by reviewing the build
target and it's dependencies. APR alone is pretty easy.
You MUST end up with apr.h derived from apr.hw fixed-file,
not the ./configure gunk.
Finally, apr.h defines those APR_DECLARE macros to be .dll
imports if you do nothing. You do need to declare -D WIN32
of course.
You only define APR_DECLARE_STATIC etc if you want to bind
to a static library of apr, and don't want to see all sorts
of noisy "importing exported symbol" warnings.

Another possibility is to use MSYS from http://www.mingw.org/ I've use
that on Windows to compile APR with not much trouble. Since you want to
port you code to multiple platforms you would probably be better served
using something like that anyway. There are two problems with using
MSYS, there is no perfect IDE for it, and for some reason the build
system as provided doesn't build the dll's, but it does build the
assemblies so you can get the dll's out of them. (It could also be
because I couldn't figure out how to make the build system do it.)
The log4cxx guys have some good instructions on compiling with MSYS and
Mingw
http://wiki.apache.org/logging-log4cxx/MSWindowsBuildInstructions
And if you want a pretty good C/C++ IDE that is free there is a good one
from the eclipse project that plays nice with the Mingw port of GCC.
The only thing you need that the log4cxx instructions don't tell you is
that you'll probably want
pkg-config so you don't have to type out the long list of linking flags.
Hope this helps.

Subject: Newbie question: Compiling helloworld-APR.c under Windows
Hello,
we are evaluating APR as a possible base for a multi-platform server
project.
I have successfully compiled and executed the following APR-"Hello
world!" program under Unix:
#include <stdio.h>
#include <apr_general.h>
int main(int argc, const char *argv[])
{
apr_status_t rv;
rv = apr_initialize();
printf( "Hello APR world!\n");
apr_terminate();
return 0;
}
Now I try to compile this with Visual Studio 8 (2005). I have
successfully built the APR libs and the test suite with Studio.
But when compiling the above program, I get the following error message:
------ Build started: Project: TestAPR, Configuration: Debug Win32

Compiling...
try-helloworld-APR.c
d:\apr\apr\include\apr_errno.h(52) : error C2061: syntax error :

d:\apr\apr\include\apr_errno.h(52) : error C2059: syntax error : 'type'
The respective line in apr_errno.c reads
APR_DECLARE(char *) apr_strerror(apr_status_t statcode, char *buf,
apr_size_t bufsize);
It seems that the macro APR_DECLARE is not defined.
I have spent one day to read all available documentation on APR and have
searched the mailing list archive for messages concerning how to compile
with APR under windows, but I just could not find out what settings I
have to specify to use the APR libs with Visual Studio.
