g ++抛出Skeleton wxwidget项目“对主要对象的未定义引用”错误

Question

Target Platform : Linux mint 9 (Ubuntu Lucid Distribution)

Compiler : g++ 4.4.3

wxwidget : 2.8

Project Title : BareBones

Files : BareBonesApp.cpp , BareBonesApp.rc , BareBonesFrm.h BareBonesApp.h , BareBonesFrm.cpp , BareBonesFrm.wxform

IDE : Nil (Made the project in wxdevcpp in windows mingw successfully compiles and executes the barebones app)

Editor : Gedit

Compiler Output & Files link : http://pastebin.com/eTMtDw9h

Observation :Something to do with IMPLEMENT_APP(BareBonesFrmApp)

Experience :Newbie

Goal :Need a solution for g++ to successfully compile BareBonesFrm.cpp

Answer 1

您不仅需要编译项目的所有cpp文件，而且还需要编译BareBonesFrm.cpp，然后它才能在IMPLEMENT_APP宏（在BareBonesApp中定义，未编译）中找到其主文件。

Answer 2

尝试添加BareBonesApp.cpp：

g++ BareBonesFrm.cpp BareBonesApp.cpp `wx-config --cxxflags` `wx-config --libs` -o BareBones
