Creating my own makefile [Error 255]

由 佐手、 提交于 2019-12-23 02:55:15
问题 I have been enjoying the luxury of coding with an IDE that writes my makefile's for me, Iv decided that I have been 'short cutting' for far to long, so I have read a few manuals and watched a few videos on makefiles and have a makefile semi-done, the only trouble that I'm having is I'm not sure how to link libraries. CPPS := $(shell ls src/*cpp) TEMP := $(subst src/,obj/,$(CPPS)) OBJS := $(subst .cpp,.o,$(TEMP)) HEADERS := $(shell ls inc/*.h) EXEC := bin/testfile all: $(EXEC) $(EXEC) : $(OBJS

cc1plus: unrecognized command line option warning on any other warning

由 亡梦爱人 提交于 2019-12-23 02:38:35
问题 I have a strange behavior of g++ that it shows a warning about unrecognized command line option, when any other warning is shown. Example: struct Foo{virtual int bar() = 0;}; struct Bar:public Foo{int bar() {return 0;} }; int main(){} Compiling with g++-5 -Wsuggest-override -Wno-c99-extensions -std=c++11 a.cpp or even g++-5 -Wsuggest-override -Wno-c99-extensions a.cpp shows: a.cpp:2:27: warning: ‘virtual int Bar::bar()’ can be marked override [-Wsuggest-override] struct Bar:public Foo{int bar

C++ Non-Integral template Const Initialization expected init-declarator before ClassName

How to force ld to use a static lib instead of shared lib?

由 一笑奈何 提交于 2019-12-23 01:53:23
问题 I am trying to build by source using the static version of the test library. I have both libtest.a and libtest.so available, so I am using the "-static" option. However, It looks like the gcc linker is also trying to search for static version the standard math library. Any idea what option I can use to link the shared versions of the standard libraries? g++ -static main.cpp -o a.out -L. -ltest Error: /usr/bin/ld: cannot find -lm 回答1: If you want to force the linker to use the static version

在Linux Mint下安装Grunt

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> [前言] 前几天重写了一个javascript的ui组件，今天在整合到与原有系统中，并且替换旧版本组件的时候，越来越感觉当前代码的组织，编写，自动化测试以及打包都很有问题。 现在javascript组件是越来越复杂，往往一个项目下来，js模块的数量还是很可观的。项目发布的时候，各种方面因素得考量我们还常常需要合并成一个文件发布。 另外如今有很多新的工具提高我们的开发效率，比如coffeescript，less，在保证第一条的时候我们当然希望以这种高效的方式进行开发。 作为编写过服务端代码的一名coder，我们会用在项目编译的时候同时运行单元测试，或者做持续集成。现在js也有很多单元测试框架，比如Chai,Mocha( 惭愧，俺一个都没有用过... )，要是javascript开发过程中也能自动运行单元测试，实现TDD等开发模式多好。 以上我们完全可以做到，使用Grunt即可。这也是我第一次使用Grunt，首先当然就是要安装Grunt了。 [操作系统] Linux mint 13 [正文] 从 Grunt Getting Started 我们可以了解到，目前Grunt要求您的计算机要安装NodeJS以及npm,其中NodeJS的版本要大于等于0.8.0。 如果您一开始图方便直接使用如下代码安装nodejs

Inheritance of virtual member functions with the same name

由 我只是一个虾纸丫 提交于 2019-12-22 17:42:47
问题 class A { A() {}; virtual ~A() {}; virtual void Start() {}; virtual void Start(float a) {}; }; class B : public A { }; class C : public A { virtual void Start(float a) {}; } ... B BObj; BObj.Start(); // -> fine, no complain from g++ ... ... C CObj; CObj.Start(); // -> not fine -> error: no matching function for call to ‘C::Start()’ ... I suspect that the problem comes from that both virtual functions have the same name, but different parameter signature. What I would like to know is that this

ISO C++ forbids variable-size array (compilation error)

由 隐身守侯 提交于 2019-12-22 16:47:22
问题 Normally I always compiled my C code like this: g++ program.c -o program.exe But my college professor requires me to compile using:g++ -o -Wall -Wextra -Werror -pedantic -std=c++0x program.exe program.c (Which is new for me). So ... I run the command and get the following error: eda.c: In function ‘int main()’: eda.c:200: error: ISO C++ forbids variable-size array ‘v’ eda.c:207: error: ISO C++ forbids variable-size array ‘nfloat’ cc1plus: warnings being treated as errors eda.c:215: warning:

g++ static link error against Boost.Log

由 蹲街弑〆低调 提交于 2019-12-22 11:12:24
问题 I get link errors when statically linking against Boost.Log. The compiler version is g++ 4.8.1. Boost version is 1.55.0. I can do a dynamical link without problems (with a "-DBOOST_LOG_DYN_LINK" in make file) but when I do the static link, I get link errors. This problem won't happen on other boost libraries. I simplified my code to reproduce this issue easily: #include <boost/log/trivial.hpp> int main() { BOOST_LOG_TRIVIAL(trace) << "test trace"; return 0; } The build command that generates
