[Mingw-users] Trouble invoking - ld - directly

[Rom <a_r...@ho...>]

 Hi folks, I'm having trouble linking with (ld) when invoked directly. 
However, when invoked indirectly (via the compiler driver), 
everything works fine. 

I've included a tiny sample program, the makefile 
and the build output. Beside the obvious things, 
"setting the lib path with -L", what else am I missing here.. ?
Your response is greatly appreciated. 

My Environment : 

Windows XP SP3
gcc/g++-3.4.5
GNU ld (GNU Binutils 2.19.1)
PMAKE (mks Toolkit make )


Many thanks..

Tiny sample program. 

//  
// g++ -Wno-deprecated main.cpp 

#include <iostream.h>
#include <strstream>
#include <iomanip.h>
#include <stddef.h>

int main(int argc, char *argv[])
{
  char buf[4096]="The quick brown fox..";
  std::strstream ss(buf,4096,ios::out);
  cout << ss.str() << endl;
  ss.clear();

return(0);
}

#----------------------
# makefile for G++ build. (WORKING WITH PMAKE) from MKS-Toolkit. 
#----------------------

APP=out
CC=g++
CPPFLAGS= -D_MSWINDOWSPC -c -g -Wno-deprecated
LIBDIR=c:\mingw\lib
LDFLAGS=-L$(LIBDIR) -lstdc++
LINKER=ld
O = .o
HDR= 
SRC= main.cpp
OBJECTS= main.o

$(APP):	$(OBJECTS)
	$(LINKER) $(LDFLAGS) $(OBJECTS) -o $(APP)
	
%$O	:	%.cpp
	$(CC) $(CPPFLAGS) $?

clean: FRC
	rm $(APP).exe
	rm *.o

FRC:

#
#--- END Sample Makefile 
#

Here is the sample output of the build. First with the variable 
LINKER=ld as per the listing of the makefile above. 

$ make -f sample.mak
g++ -D_MSWINDOWSPC -c -g -Wno-deprecated main.cpp
ld -Lc:\mingw\lib -lstdc++ main.o -o out
main.o: In function `ZSt17__verify_groupingPKcjRKSs':
C:/mingw/bin/../lib/gcc/mingw32/3.4.5/../../../../

.

.
. (The link errors continue on... ) 
.
make: Error code 1 


Now, the output of the build with the variable LINKER=g++ instead. 

$ make -f sample.mak 
g++ -D_MSWINDOWSPC -c -g -Wno-deprecated main.cpp
g++ -Lc:\mingw\lib -lstdc++ main.o -o out
$ ls out.exe
out.exe
$ out.exe
The quick brown fox..
