首先,我使用g ++(实际上是'fltk-config --compile')编译了以下代码,并且可执行文件在Linux上运行正常。但是当我尝试在针对Windows的Linux上使用'mingw32'编译代码时,我遇到了错误:
#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Button.H>
int main(int argc,char**argv){
Fl_Window*Fl_Window_Ptr=new Fl_Window(400*1.618,400,"My second window");
Fl_Window_Ptr->begin();
Fl_Button*Fl_Button_Ptr=new Fl_Button(10,400-40,30*1.618,30,"Hi, I mean, hello world!");
Fl_Window_Ptr->end();
Fl_Window_Ptr->show();
return Fl::run();
}
当我尝试使用'mingw32'编译时:
user@computer:~/Documents$ i586-mingw32msvc-g++ 'fltk-config --cxxflags' 2016_02_06a_1st_Window.cxx 'fltk-config --ldflags' -o 2016_02_06a_1st_Window.exe
发生此错误:
i586-mingw32msvc-g++: fltk-config --cxxflags: No such file or directory
i586-mingw32msvc-g++: fltk-config --ldflags: No such file or directory
2016_02_06a_1st_Window.cxx:1:19: error: FL/Fl.H: No such file or directory
2016_02_06a_1st_Window.cxx:2:26: error: FL/Fl_Window.H: No such file or directory
2016_02_06a_1st_Window.cxx:3:26: error: FL/Fl_Button.H: No such file or directory
但是,仅举几例,以下命令很好,可执行文件在Linux环境中有效:
user@computer:~/Documents$ fltk-config --compile 2016_02_06a_1st_Window.cxx
我的灵感来自this post。
答案 0 :(得分:0)
正如“Ulrich Eckhardt”评论的那样,解决方案是修改反引号的使用。最后,以下shell脚本解决了上一个错误:
#! /bin/bash
#This script compiles C++ source codes with MinGW32 with FLTK compile/link flags
echo "Getting fltk-config --cxxflags.."
fltk_config_cxxflags=$(fltk-config --cxxflags)
echo "Getting fltk-config --ldflags.."
fltk_config_ldflags=$(fltk-config --ldflags)
#echo $fltk_config_cxxflags
#echo $fltk_config_ldflags
cxx_source="2016_02_06a_1st_Window.cxx"
exe_output="2016_02_06a_1st_Window.exe"
echo "i586-mingw32msvc-g++ $fltk_config_cxxflags $cxx_source $fltk_config_ldflags -o $exe_output"
echo "Compiling and linking.."
i586-mingw32msvc-g++ $fltk_config_cxxflags $cxx_source $fltk_config_ldflags -o $exe_output
echo "End of script"
现在已经解决了上一个错误,但是,我遇到了 无法找到-lXext 的新错误,这可以在终端输出中看到:
user@computer:~/Documents$ ./2016_02_07a_script.sh
Getting fltk-config --cxxflags..

现在我正在尝试解决新错误!
