Hi, I want to port an application written in C into C++. When compiling the code with the C compiler (gcc) some of the variables are compiled as common symbols that the linker treats without problems. But when I compile the code with g++ these common symbols are put in BSS section and at link time, the linker reports for multiple definitions of the same variable in different object files. Before writing here, I looked for some solution and as I understand the -fconserve-space flag is supposed to solve my problem. There is another posting in the mail grup that relates to -fconserve-space flag that it doesn't have any effect (http://gcc.gnu.org/ml/gcc-help/2004-08/threads.html#00008). The suggested solutions are to define the variables that cause the problem as either static or extern. Static definition changes the logic/semantics of the application, whereas the extern declaration will involve a lot of code refactoring :( I would welcome all the comments that would save me the huge burden of code rewriting.
