I have not tried the stl yet but I will try. My suggestion is to use g++ =
instead of gcc. With g++, the libraries you used (lstdc++, g++) are =
linked by default, so you do not need to use option '-l' to link them. I =
hope this can solve your 'multiple definition' problem. eg, tye the =
following simple command:
g++ -c xx.cc
g++ -o xx.exe xx.o ...

Subject: ld problem with templates
dear sirs,
I tried to compile a program that uses stl extensivly.
There is no problem to compile it with gnu 2.7.2 under solaris, linux
and OS/2.
Using gnuwin32 causes hundreds of linker errors like this:
.... multiple definition of __default_alloc_template<false,0>::...
(all errors occured contain '__default_alloc_template<false,0>::' !)
Is it a known problem? Should I use other ld options?
options to compile cc files were :
gcc -c xx.cc
options to link the executable were :
gcc -o xx.exe xx.o ... -lstdc++ -lg++ -lm
thanks
S. Triebel
