问题 I tried to run a program on opencv but got the following error: test_1.cpp:(.text+0x44): undefined reference to `cv::imread(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int)' I learnt that the order of sources and libraries on the link line matters So, running g++ -o test_1 test_1.cpp pkg-config opencv --cflags --libs works. However, how can I setup code blocks so that when I build the code, it applies the correct order? 来源： https://stackoverflow.com

问题 I need to obtain the information on the C-compiler used to build an installed program. I am guessing a rt or a lib can report that, but nothing concrete. Not that the program would be installed in /usr/... or a similar place, and hence would not have access to the build directory to get the relevant info. 回答1: Well behaved programs should understand the --version argument. Packaged programs (i.e. those installed with dpkg -i or apt-get install of a .deb package on Debian, etc...) also know

问题 As the title suggests, I'm getting the above error with code that was working 6 days ago. Code since omitted - apologies DurationCombo is an ActiveX ComboBox which resides on Sheet1.

Is there an easy way to do that? My first attempt is something like: <ItemGroup> <Compile Include="%(PEG.Identity)" Condition=" '$(Compile)' != '%(PEG.Identity)' " /> <

问题 I'm able to debug a C program in Visual Studio 2008 and build it. However, the build process doesn't seem to leave an .exe in the folder it builds in. Regardless of if I choose Release or Debug. Could the .exe be sent somewhere else? How can I tell? Contents of the Debug folder under the main folder of the project: cl.command.1.tlog CL.read.1.tlog CL.write.1.tlog ConsoleApp.Build.CppClean.log ConsoleApp.exe.embed.manifest ConsoleApp.exe.embed.manifest.res ConsoleApp.exe.intermediate.manifest

问题 I have been looking at Javascript templating engines trying to find a way to have standard templates available on/offline. Currently I'm kind of stuck at dustjs/linkedIn which would require to server-side pre-compile a template into a js file - difficult as I'm using Coldfusion8 . There are sparse links available on running Javascript in Coldfusion (example). So: Question: Is there an easy to use Javascript in Coldfusion? I'm not talking about toScript our <cfoutput><script>alert("hello")><

问题 An excerpt from "Exceptional C++": "In the old days, you could just replace "#include " with "class ostream;" in this situation, because ostream used to be a class and it wasn't in namespace std. Alas, no more. Writing "class ostream;" is illegal for two reasons: ostream is now in namespace std, and programmers aren't allowed to declare anything that lives in namespace std. ostream is now a typedef of a template; specifically, it's typedef'd as basic_ostream. Not only would the basic_ostream
