More and more 64-bit systems are showing
up on the market—and developers are porting
their applications to these systems. Most code
runs directly without problems—but there is a
number of sometimes quite subtile problems
that developers have to be aware of for portable
programming and porting.
This paper illustrates some problems on porting
an application to 64-bit and also shows
how use a 64-bit system as development platform
for both 32-bit and 64-bit code. It will
give hints especially to application and library
developers on writing portable code using the
GNU Compiler Collection.
