linker

问题 As i understand Dynamic loading means loading the library (or any other binary for that matter) into the memory during load or run-time. so in program below when dlopen() called dynamic loader will come in to picture and it will load the lib in to the memory if library is not loaded already. Dynamic linking refers to the linking that is done during load or run-time. and it resolves external references. So in program below dlsym() function will ask for cosine function and dynamic linking will

问题 I would like to remove all unused symbols from my compiled C++ binary. I saw this, which gives an overview using gcc, which is the toolchain I'm using: How to remove unused C/C++ symbols with GCC and ld? However, on my system, the linking option ( -Wl,--gc-sections ) is rejected: $ gcc -fdata-sections -ffunction-sections a.c -o a.o -Wl,--gc-sections ld: fatal: unrecognized option '--' ld: fatal: use the -z help option for usage information collect2: error: ld returned 1 exit status I'm

问题 "file was built for archive which is not the architecture being linked (armv7s)" do I need to wait for people to release new binaries or I have a way out, I get this for GoogleAnalytics Restkit ... EDIT: problem with Restkit solved with their latest commit, just pull from github, 回答1: Yes, they will have to release binaries which are compiled for armv7s architecture to support the new iPhone 5 A6 processor. In the meantime, you can temporarily compile against only armv7 to continue

问题 I've updated my Xamarin.Android app package MvvmCross from 5.3.2 to 5.4 and app start crashing on startup. Manually I identified that the reason is the linker - I have link SDK libs only option enabled. With the None option it works just fine but makes a twice bigger package. The type initializer for 'MvvmCross.Core.Platform.LogProviders.ConsoleLogProvider' threw an exception. ---> System.NullReferenceException: Object reference not set to an instance of an object 回答1: This is a known bug in

问题 I can not fully understand the code result when exist override ambigous function. I have a libray libMy , which contains two class A and B . The code shows as follows // A.h #ifndef included_A_h #define included_A_h class A { public: void print(); }; #endif // A.cpp #include "A.h" #include <iostream> void A::print() { std::cout << "A from library" << std::endl; } // B.h #ifndef included_B_h #define included_B_h class A; class B { public: void printA(A &a); }; #endif // B.cpp #include "B.h"

问题 I have a rather huge .dat-file (896MB) included as a BIN resource in my project. Now I get a LNK1106 link error ("fatal error LNK1106: invalid file or disk full: cannot seek to 0x382A3920".) I use Visual Studio 2005 under Windows XP, and have tried on a 4GB RAM machine with high Virtual Memory settings and lots of disk space. I have tried a number of different optimization flags, but to no avail. Does anyone have a clue? EDIT: I have narrowed it down to a specific size of the compiled

问题 I've got an issue where CMake can't detect pthread. As a work-around I tried: set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -lpthread") However, this inserts -lpthread in the wrong place: /usr/bin/c++ -std=c++11 -D_GNU_SOURCE -Wall [manyflags ...] -lpthread \ CMakeFiles/connectivity_tool.dir/connectivity_tool/conn_tool.cpp.o \ -o connectivity_tool -rdynamic -lboost_system [many libraries...] This results in: /usr/bin/ld: /tmp/ccNvRifh.ltrans3.ltrans.o: undefined reference to symbol

问题 I'm using C language on windows. This question was previously part of What happens to identifiers in a program? . I broke it to reduce no. of questions. This is a standalone query (doesn't depend on the previous question) If there is nothing to link (i.e.. I'm not using any libraries. I know it wont be of any use.) will the linker change the object code output of assembler? If so what does it change? I heard that LINKER also does the operation of some memory mapping. I don't understand how.

问题 I have some text in a UITextView, that I would like to have show as blue, and serve as a link to a website. How do I do that in interface builder? 回答1: In Interface Builder, select the UITextView, open the inspector, go to the Text View Attributes tab, then make share "Detect Links" is checked. This only works for items that look like links (http://stackoverflow.com) For making arbitrary links, then you will want to use a UIWebView instead. 来源： https://stackoverflow.com/questions/2489950/how

问题 So I'm compiling the examples for libgstreamermm-0.10, and I've run into an issue with CMake. With the version of libgstreamermm-0.10 that is installed by default on my system, the example segfaults. OK, so I got the latest sources and installed them to /usr/local and get the new example. Everything's looking good. g++ main.cc player_window.cc -o test `pkg-config --cflags --libs gtkmm-3.0` `pkg-config --cflags --libs gstreamermm-0.10` works fine and as expected. Great, now to try and get it
