When building with my own make using MinGW, mongoose.c, mongoose.h I get this
same
error. pid_t is defined twice.

I'm not sure how correct this is, but I did get this to build.
I got this working by not using pid_t directly. I replaced pid_t with
'procesID' and
then conditionally typedef'd processID in windows vs unix
// For Windows and MinGW
typedef HANDLE processID;
// for Unix
typedef pid_t processID;
spawnProcess would return a processID and kill would take a processID. sendCGI
would
also use processID instead of pid_t
I only tested this under minGW though, and only compiled so far. But seems like
it
should avoid the conflict.

It looks like the pid_t issue has been partially addressed in
"$Id: mongoose.c 327 2009-05-05 14:11:04Z valenok $"
but using Eclipse-3.4.2/CDT-5.0.2/MinGW-3.15.2 I also had to define
"_NO_OLDNAMES" to
avoid the error (as used in sys/types.h). This macro definition doesn't appear
to be
in the Makefile.

@guy.lancaster: I've tried to use the options -D_NO_OLDNAMES in the makefile,
but it

I thought that defining _NO_OLDNAMES had resolved the problems so I reverted my
other
changes last night but this morning it's back to the original problems.
Is anyone able to build it under MinGW? If not, did it ever build? Knowing the
history will help to understand what may be needed. BTW, I haven't tried to
link it
yet so there may be more issues.
I have to return to the client-side of my project for a while so there's time to
speak up if there are any suggestions before I get back to this.
Thanks.

I've understood how to fix this!
I've searched on some forums/mailing lists (and in particular this
http://gcc.gnu.org/ml/gcc-bugs/2004-03/msg01944.html ), and it seems that when
you
try to use "gcc -v example.c" it shows you all the paths in which it will
search for
libraries and so on.
So I've just read that when I gave the command 'gcc -v example.c' (this is the
code)
#include <sys/types.h>
#include <stdio.h>
typedef int pid_t;
int main()
{
pid_t pid = 5;
off_t p = 6;
printf("Pid %d %d\n", pid, p);
}
It showed me some lines, and one (or more) of these were:
ignoring nonexisting directory mingw/include
So I've renamed the mingw directory; it was C:\MinGW4-4. I've renamed it to
'c:\mingw'. Then I've fixed the environment variables (PATH, since it pointed to
mingw4-4) and tried to compile the example (see here for the log
http://pastebin.com/f451ce8ca ) and then mongoose.
C:\mongoose-2.8\mongoose>mingw32-make mingw
gcc -W -Wall -mthreads -Wl,--subsystem,console -DNDEBUG -Os -DHAVE_STDINT mongoo
se.c -lws2_32 \
-shared -Wl,--out-implib=mongoose.lib -o _mongoose.dll
mongoose.c: In function 'mg_stat':
mongoose.c:1088: warning: integer constant is too large for 'long' type
Creating library file: mongoose.lib
gcc -W -Wall -mthreads -Wl,--subsystem,console -DNDEBUG -Os -DHAVE_STDINT mongoo
se.c main.c -lws2_32 -ladvapi32 -o mongoose.exe
mongoose.c: In function 'mg_stat':
mongoose.c:1088: warning: integer constant is too large for 'long' type
Only some warnings without using -D_NO_OLDNAMES!! :)
PS: Please note that now it says "ignoring duplicate ..." while it said
"ignoring
nonexisting .."!
Now it works very well :)
Bye!

@marcusbu
I'm not sure I understand your 'fix'. Moving my MinGW directory or installing
it off
root does not sound right to me at all.
The hello example you mention does compile if pid_t is an int. But doesn't if
you
use HANDLE as demonstrated below. So is this a fix or did you just get lucky?
#include <sys/types.h>
#include <stdio.h>
#include <windows.h>
typedef HANDLE pid_t;
int main()
{
pid_t pid = 5;
off_t p = 6;
printf("Pid %d %d\n", pid, p);
}

I've compiled mongoose without problems, as you can see. The only warning I got
was:
"integer constant is too large for 'long' type"
It however means that "typedef HANDLE pid_t" works fine.
I think it can be a solution, since gcc checked for the 'mingw/include' where
are
defined all the headers (sys/types.h and so on) but it couldn't find them.
Have you tried to rename your installation path?
It should be "c:\Mingw\" and not "C:\program files\mingw" and similar.
I don't know exactly why this happens (maybe the --prefix=/mingw doesn't work on
windows?), but as you can see also here (
http://web.archive.org/web/20041026163202/http://www63.tok2.com/home/bitwalk/dow
nload.html
), it's a well established fact that you must use C:\mingw.
Bye!

Does not work for me. I moved my MinGW to c:/mingw neither builds when using
HANDLE.
And I haven't had any issues using the MinGW in my Qt directory with anything
else so
I'm not sure why the c:/mingw works for you.
You could be right its a MinGW problem, but I can't build mongoose even if
c:/mingw
is the install i use.
BTW HANDLE for my install is defined as a void* not an integer.
Incidentally it does find the headers, that's part of the problem. pid_t is
defined
twice.
Thanks for the help.

I wonder *why* pid_t is defined twice? in mongoose.c, pid_t is defined under the
_WIN32 conditional, which I though is not visible under mingw.

Yes the win32 conditional is enabled. (In netbeans I can see the conditional
code that
is active.)
Also, I noticed marcusbu used gcc 4.4. I just spent an hour setting that up.
Still
fails.

@doug:
you're right. I don't know why I had mongoose.c modified (I had typedef HANDLE
processID; and all the pid_t were processID). What a really boring error!
@valenok:
when you use mingw, these macros are automatically defined:
http://pastebin.com/m762bb463
as you can see the second line says "_WIN32 1"
I've also tried to use -U_WIN32 in the makefile, but I get these errors:
