Compilation error with JK flipflop module

Siva Chandra — Thu, 01 Mar 2007 06:53:45 -0000

There has been a slip-up in the constructor of the JK flipflop module (please see the file lcs/jkflipflop.h). The function onStateChange needs a parameter. Currently, the function is called in the constructor without a parameter. It has to be changed to

onStateChange(4)

since 4 is the reset port Id.

This will be corrected in the next release numbered 0.0.53.

libLCS-0.0.45 :: Replace the file lcs/vcdman.h

Siva Chandra — Mon, 04 Dec 2006 04:42:36 -0000

If you are using libLCS-0.0.45, kindly replace the file lcs/vcdman.h with the file attached. This fixes the bug which does not produce a valid VCD file when only one variable is being dumped.

Declaration of Bus and InputBus classes in the file line.h

Siva Chandra — Mon, 13 Nov 2006 10:21:09 -0000

I have, for the first time, built libLCS-0.0.34 with
gcc-4.1.1 and have got a build failure. Previously,
when I have built using gcc-3.4.x, there were no build
failures. With gcc-4.1.1, the error occurs in the file
line.h. The class Line is defined in this header file.
Classes Bus and InputBus are declared as friends of the
class Line. However, gcc-4.1.1 is complaining when I
make use of these friend classes as return types and
function argument types. The fix is to declare the
classes Bus and InputBus in the namespace before the
definition of class Line. It has to be done as follows.

In file line.h:

namespace lcs
{

template <int w> // This line should be added.
class Bus; // This line should be added.

template <int w> // This line should be added.
class InputBus; // This line should be added.

class Line
{
...
};

}
