How can I get gcc to add a prefix to all symbol names

阅读更多关于 How can I get gcc to add a prefix to all symbol names

问题 I know that in the past there was an option -fprefix-function-name that would add a prefix to all generated symbols, it doesn't seem to be part of gcc anymore. Is there any other way to do this? 回答1: I believe this answer will give you the solution. In short, you can 'prefix' symbols in an existing library using objcopy like this: objcopy --prefix-symbols=foo_ foo.o 回答2: *EDIT: George Skoptsov's solution's better than mine :) The nm trick might come in handy though. This is not exactly what

How to reduce compile time for large C++ library of individual .cpp files?

阅读更多关于 How to reduce compile time for large C++ library of individual .cpp files?

问题 We're developing a C++ library with currently over 500 hundred individual .cpp files. These are each compiled and archived into a static library. Even with a parallel build, this takes some minutes. I'd like to reduce this compilation time. Each file is on average 110 lines with a function or two inside. However, for each .cpp file there is a corresponding .h header and these are often included by many of the .cpp files. For example, A.h might be included by A.cpp , B.cpp , C.cpp , and so on.

Sass::SyntaxError: Undefined mixin 'mixin_name'

问题 I'm working on a Rails 4 project where I'm using Sass and Sass's @import to combine multiple css into one. It works fine but not if I use a new partial for mixins ( _mixins.css.scss ) and @import this in main.css.scss only and use mixins any other file which is added after that _webapp.css.scss @import "bootstrap/bootstrap"; @import "responsive/mega_menu"; @import "responsive/mixins"; @import "responsive/webapp"; Rails Precompilation process is unable to find " responsive/mixins " and gives

What is the best way to flush precompiled perl6 modules?

阅读更多关于 What is the best way to flush precompiled perl6 modules?

问题 I am trying to refactor some code. My approach (using vi) is to copy my old libraries from /lib to /lib2. That way I can hack out big sections, but still have a framework to refactor. So I go ahead and change mymain.p6 header from use lib '../lib'; to use lib '../lib2'; . Then I delete a chunk of the lines in ../lib2/mylibrary.pm6 and make darn sure :w is doing what I expect. Imagine my surprise when my program still works perfectly despite having been largely deleted. It even works when I rm

ASP.NET in-place precompile doesn’t work as expected

阅读更多关于 ASP.NET in-place precompile doesn’t work as expected

问题 I am trying to use ASP.NET precompile tool aspnet_compiler.exe to compile site after it has been deployed. As per book definition running in-place precompile on web machine should improve first page load experience. The compilation tool compiles each ASP.NET page, storing the compiled version in the %WINDIR%\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files folder just like if the pages had each been visited for the first time from a browser. In-place precompilation can speed up the

What do I specify as the “target folder” parameter to ClientBuildManager constructor?

阅读更多关于 What do I specify as the “target folder” parameter to ClientBuildManager constructor?

问题 I'd like to experiment with the fourth parameter of ClientBuildManager class constructor that lets me specify the compilation options. The problem is I have to provide the third parameter that specifies the "target folder". Previously I used the two-paremeters constructor like this: VirtualDirectory dir = ...; using( var buildManager = new ClientBuildManager( dir.Path, dir.PhysicalPath ) ) { buildManager.PrecompileApplication(); } and it worked okay - the two parameters are quite obvious. I

问题 I'm currently running a CI build and deploy using TFS 2013 for the build and Release Management 2013 for the deployment, though I need the web applications (WebForms) that I'm deploying to be precompiled. I'm looking to use a publish profile to drive the precompilation before the output is copied to the drop location, but I haven't found anything that has been able to do this yet. After finding How do I configure MSBuild to use a saved publishProfile for WebDeploy? , I set up a publish

阅读更多关于 How to make GCC evaluate functions at compile time?

问题 I am thinking about the following problem: I want to program a microcontroller (let's say an AVR mega type) with a program that uses some sort of look-up tables. The first attempt would be to locate the table in a separate file and create it using any other scripting language/program/.... In this case there is quite some effort in creating the necessary source files for C. My thought was now to use the preprocessor and compiler to handle things. I tried to implement this with a table of sine
