compilation

问题 In the CImg Makefile I notice a flag "-lm" I think this points to the m.lib file. But for some reason it cannot find it during the Linking phase. I am compiling the code using the following command: nvcc -o FilledTriangles FilledTriangles.cu -I.. -O2 -lm -lgdi32 "nvcc" is just the nvidia CUDA compiler. It should function similar to g++ 回答1: -lm refers to "libm.so" In general, -lXYZ is a way of telling the linker that it should resolve the symbols in your compiled code against libXYZ.so (after

问题 First, I'd like to say that I've spent a lot of time searching for an explanation/solution. I've found hints of the problem, but no way to resolve my particular issue. Hence the post on a topic that seems to have been beaten to death in at least some cases. I have a Java test class that tests for proper encoding/decoding by a Mime utility. The strings used for testing are declared in the source file and we use assertEquals() to test equality after processing the input string. Here's an

问题 In Ubuntu 12.04 Precise the only way to get breakindent patch working in VIM seems to be compiling VIM itself after patching it. Here's what I've done: Install pbuilder and create local environment sudo apt-get install pbuilder debootstrap sudo pbuilder create --debootstrapopts --variant=buildd Get the sources sudo apt-get source vim Patch them with breakindent patch retrieved from the official repo cd vim-7.3.429 patch -p1 < vim-breakindent.patch sudo pbuilder build vim_7.3.429-2ubuntu2.1

问题 Been working on this for hours now so any insight would be greatly appreciated. I'm trying to compile libssh2 for the iPhone Simulator on OS X (I already have it compiled successfully for the device). I'm using the following environment variables and commands: export DEVROOT=/Developer/Platforms/iPhoneSimulator.platform/Developer export SDKROOT=$DEVROOT/SDKs/iPhoneSimulator3.0.sdk export CC=$DEVROOT/usr/bin/gcc-4.2 export LD=$DEVROOT/usr/bin/ld export CPP=$DEVROOT/usr/bin/cpp-4.2 export CXX=

问题 A little backstory (ok, a lot): I've been working on creating classes that take java.util.function types and wrap their execution with try/catch blocks to remove the need for using try/catch from within lambda statements. Something that would allow this test code: list.forEach(ExceptionWrapper.wrapConsumer(s -> {throw new Exception(s);})); In doing so, I came up with this. It did not work. public class ExceptionWrapper { public static <T> Consumer<T> wrapConsumer(Consumer<T> consumer){ return

问题 Lets say I have these files: main.cpp , ClassA.cpp , ClassA.h , ClassB.cpp , ClassB.h The main has #include "ClassA.h" and #include "ClassB.h" and each .cpp file includes its respective .h file. Is this correct? Now I am compiling using g++ *.cpp after which I get an executable a.exe (Windows) And my question is that is this the right way? And lets say if I only make changes in one file (cpp or h)will this command also recompile the unchanged files(because I see no new files in the folder

问题 Got this error when compiled java code in ubuntu. error: illegal character: '\ufeff' import java.net.*; ^ error: class, interface, or enum expected import java.net.*; ^ 回答1: As Jim Garrison pointed out, you probably have a Byte Order Marker (BOM) at the start of the file. Use an editor that can view all non-printable characters and remove it. Alternatively, you can use sed to remove it: sed '1s/^.//' infile >> outfile 回答2: Use another editor because it seems to be an eclipse UTF-8-BOM problem

问题 An upcoming move of our Data Warehouse has us needing to change many Connection Strings and UNC File Paths located in VBA Script Tasks within DTSX Packages. We've performed a mass find-and-replace but when changing Script Tasks using this method, the binaries run during DTSX Package execution don't get recompiled at run time, resulting in the find-and-replaced changes not being reflected in the Script Task's execution. I've found some articles on how to do it in SQL Server 2008 and 2012, but

问题 I'm trying to build libpng in MS Visual studio 2015 community edition but when i built it, i got this error (i used cmake to compile libpng along with compiled zlib to produce libpng's soln file ALL_BUILD.vcxproj ) Cannot open include file: 'pnglibconf.h':No such file or directory I think this a system specific error,when i try to build this on other system it works fine(because pnglibconfig.h was present with MS VS soln folder). Is there any prerequisites that is missing? Update: I tried

问题 I couldn't seem to find an answer to this on the web. Since C# is a compiled language, how is code inside a Razor view able to execute without the developer having to build again? For example, if I load a page with this code: @{string test = "123";} . But then change the code to this: @{string test = "test";} How do I not need to rebuild? Also, is the thing that is allowing this to happen a C# feature or an MVC feature? 回答1: The razor engine basically "compiles" the view. Something like this.
