问题 I am trying to build an Xcode iOS project I haven't touched since last June. I know there have been some updates with packages and something with Swift 4.2 but I got a multitude of errors.

问题 I'm trying to experiment around in ncurses for the first time, but I'm having problems compiling my source code. As far as I can tell, ncurses is installed and in the proper directories. My makefile is super simple: .cpp : g++ -Wall -g -o $* $*.cpp -std=c++11 -lncurses and here's my output when I try to locate ncurses.h $ locate ncurses.h /usr/include/ncursesw/ncurses.h and when I check to see if it's installed $ dpkg -l | grep ncurses ii libncurses5:amd64 5.9+20140118-1ubuntu1 amd64 shared

问题 I am developing a library and need to make sure it compiles with 4.1.2(I know, it brings me no pleasure). So on a Fedora 14 Machine I downloaded, compiled and installed GCC41. Now in CMake I only change the following to variables CMAKE_CXX_COMPILER=/opt/gcc41/bin/c++41 CMAKE_C_COMPILER=/opt/gcc41/bin/gcc41 It compiles fine, but it seems to use the wrong version of the standard library. The error(s) I get look like this: /opt/gcc41/bin/c++41 -Wall -Wold-style-cast -Wsign-compare -Wnon-virtual

问题 I Had VS2010 installed but found that intellisense wasn't working. I looked on the web and found that I wasn't the only one who had that issue. So, I installed VS2008 and everything was fine. Then I decided to clean up my computer and removed VS2010 and immediately started getting this error on my programs (new and old). Even a simple test program that has one cout command. I tried repairing VS2008 and that didn't work so I tried to uninstall and then reinstall and still I am getting the same

问题 I'm trying to link my XPCOM extension against the 1.9.3a3pre SDK and I get the following: error LNK2001: unresolved external symbol _moz_xmalloc So, what lib do I need to link to? The documentation doesn't say. This is on Windows right now, but I'll need it to build on Mac and Linux (32bit/64bit) as well. Edit: Now with bounty. Edit: Update: Turns out FF3.7 was cancelled. So I don't have to worry about this until FF4. 回答1: define ' XPCOM_GLUE ' in C++ Preprocessor Definition property. It will

问题 I am using the following components of Boost 1.53.0 in conjunction with C++11 libraries... boost::signals2::scoped_connection boost::signals2::signal boost::signals2::connection boost::math::constants boost::circular_buffer boost::lexical_cast According to this answer, I do not need to link against libraries to use these parts of Boost. According to this answer, signals2 should be header-only also. However, I still receive linker errors... Undefined symbols for architecture i386: "boost:
