specific instantiation of static members from template class

[cedric]

hello, I have a problem when I try to instantiate static members. this code 
works with gcc-3.4.5 but not with gcc-4.0.2 (debian sid).
here a test case with 3 files :


/ main.cpp
#include 
#include "Test.h"

int main(int argc, char **argv)
{
std::cout << TestInt::member << std::endl;
return 0;
}

/ test.h
template 
class Test
{
public:

static T member;
};

typedef Test TestInt;

/ test.cpp
#include "Test.h"

template class Test;
template<> int Test::member;


I got an error at link because it cannot find the symbol Test::member 
used in "main.o"
If I use only one file, it works.
If I give an initial value to Test::member in test.cpp, it works.
It works with gcc-3.4.5.

I did some research and see that it could works even without the member 
declaration, the class instantiation should be enough here :

Is this a bug or a behavour change from gcc ?

Re: gcc command line exceeds 8191 when building in XP

Hi,

I'm building a project using GNU gcc, but the command line used to build
each source file sometimes exceeds 8191 characters, which is the maximum
supported command line length under Win XP.Even worst under Win 2000,
where the maximum command line length is limited to 2047 characters.

Can the GNU gcc read the build options from a file instead ?I have
searched, but cannot find an option in the documentation.

Thanks in advance,

redirecting to gcc-help.
The gcc builds for Windows themselves use a scheme for splitting the 
link into multiple steps in order to deal with command line length 
limits.  I would suggest adapting that.  Can't study it myself now while 
travelling.




@file says the manpage. "Read command-line options from file."
