Hi, This problem is related to This question I asked yesterday. Now it seems that the linker flag --whole-archive forces the test object to be included in the binary. However, in linking with, g++ main.cpp -o app -Wl,--whole-archive -L/home/dumindara/intest/test.a -Wl,-no--whole-archive I get the following error: /usr/lib64/gcc/x8...
Hi, I have 3 tiny files which I use to make a static library and an app: test.h #ifndef TEST_H #define TEST_H class Test { public: Test(); }; extern Test* gpTest; #endif test.cpp #include "test.h" Test::Test() { gpTest = this; } Test test; main.cpp #include "test.h" #include <iostream> using namespace...

Hi, This is a new question after my long rant. The problem here is, I have a global vector<Base*> vObjs in my main application and I got Derived objs in each static lib linked to the application. If I specify the vObjs to have an init_priority of 101 and each obj in static libs to have say... 1000, is it guaranteed that vObjs will ...
Ok I'm trying to get my head around g++ and librarys. I have a few files that I've compiled into a library from the make file $(CC) -fPIC -c -o $@ $< -O2 -D__PS2 then $(CC) -shared -o $@ $(OBJ_FILES) -O2 -D__PS2 this compiles fine. from the program that uses the lib $(CC) -c -o $@ $< -I./ compiles fine $(CC) -o $@ $(OBJ_FILES...

Hi, I have a very large code, a lot of which is legacy code. I want to know which of all these files are taking part in the compilation. The code is written in GNU compilers and mostly in C/C++, but some in other programs too. Any advice will be highly appreciated. Thanks, Moshe. I am compiling under linux with a mix of scripts/...
I'm using cygwin and when I'm compiling hello world with gcc somehow the compiler doesn't understand about using std namespaces (some of them are missing), but when I compile with g++ yes they work. But when I click on the helloworld.exe it says that cygwin1.dll is missing. Is there anything can I do? ...

I'm trying to use G++ to compile some C++ code. It seems to work fine in other compilers, but for whatever reason, G++ won't produce working output. Disclosure: This is part of a homework assignment, but I feel like it's more of a compiler issue, since it works in other compilers. Here's the snippet that's wreaking havoc: set<int> t1,...

Hi all, I'm experimenting with C++0x threading, partially implemented in gcc 4.5 and I've got a problem, which I can't understand.
