Question

我正在使用Ubuntu中的wxWidgets开发一个hello-world级程序。

代码用

编译

g++ HelloWorld.cpp `wx-config --libs` `wx-config --cxxflags` -o HelloWorldApp -I../inc

maot@HP-Pavilion-dv7:~/Perforce/maot_HP_Pavilion_dv7_full_02/WxWidgets/Learning_01/src$ which wx-config
/home/maot/Perforce/wxWidgets-3.1.0/gtk-build/wx-config
maot@HP-Pavilion-dv7:~/Perforce/maot_HP_Pavilion_dv7_full_02/WxWidgets/Learning_01/src$

...这是有道理的，因为我将路径放在PATH环境变量中的wx-config。我自己编译了wxWidgets。

现在我想使用cmake。我的CMakeLists.txt文件尝试：

cmake_minimum_required(VERSION 2.8.9)
project(WxWidgets_Learning_01)

set(CMAKE_CXX_COMPILER /usr/bin/g++)

message("CMAKE_CXX_FLAGS_DEBUG = ${CMAKE_CXX_FLAGS_DEBUG}")
message("CMAKE_CXX_FLAGS_RELEASE = ${CMAKE_CXX_FLAGS_RELEASE}")

set(CMAKE_CXX_FLAGS_DEBUG " -g3 ")
set(CMAKE_CXX_FLAGS_RELEASE "")

message("CMAKE_CXX_FLAGS_DEBUG = ${CMAKE_CXX_FLAGS_DEBUG}")
message("CMAKE_CXX_FLAGS_RELEASE = ${CMAKE_CXX_FLAGS_RELEASE}")

include_directories(../inc)
include_directories(../api/IBJts/source/cppclient/client)
include_directories(../api/IBJts/source/cppclient)

# wxWidgets header files start
include_directories(/home/maot/Perforce/wxWidgets-3.1.0/include)
include_directories(/home/maot/Perforce/wxWidgets-3.1.0/gtk-build/lib/wx/include/gtk2-unicode-3.1)
# wxWidgets header files end

# wxWidgets defines start
add_definitions(-D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -D__WXGTK__)
# wxWidgets defines finish

# Directories with wxWidget libs start
link_directories(/home/maot/Perforce/wxWidgets-3.1.0/gtk-build/lib)
# Directories with wxWidget libs finish

SET(wxWidgets_ROOT_DIR /home/maot/Perforce/wxWidgets-3.1.0/gtk-build/lib)
SET(wxWidgets_CONFIGURATION mswud)

# https://cmake.org/cmake/help/v3.0/module/FindwxWidgets.html
# Note that for MinGW users the order of libs is important!
find_package(wxWidgets COMPONENTS net gl core base REQUIRED)
include(${wxWidgets_USE_FILE})

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wextra -Wall -pthread -lm ")

file(GLOB sources "../src/*.cpp" )
file(GLOB headers "../inc/*.h" )

set(daytrading_sources ${sources} ${headers})

add_executable(WxWidgets_Learning_01 ${sources})
target_link_libraries(${PROJECT_NAME} ${wxWidgets_LIBRARIES})

输出：

我认为find_package找不到wxWidgets，我不明白为什么。我不确定这个mswud的事情因为我找不到关于它的解释; ms听起来像比尔G.我已经为wxWidgets_ROOT_DIR尝试了一些值，但没有运气。欢迎任何帮助：wxWidgets_ROOT_DIR应该有什么价值，mswud有什么好处？

===编辑以下===

我使用--prefix = $（pwd）选项跟随https://wiki.wxwidgets.org/Compiling_and_getting_started。不需要make install，它就是sais。

如何将wx-config的结果放入CMakeLists.txt？

maot@HP-Pavilion-dv7:~$ wx-config --cxxflags

maot@HP-Pavilion-dv7:~$ 
maot@HP-Pavilion-dv7:~$ wx-config --libs

我使用下面的CMakeLists.txt文件编译并运行我的代码;我意识到这不是预期的方式。

如果你只需要为原型编译一个简单的例子就可以了。

但是，如果你需要编译一些大项目 - 你可以尝试设置Anjuta / CodeBlocks / CodeLite来提供帮助。从长远来看，它将使您受益（特别是CodeBlocks）。

就你的问题而言：mswud并不好，因为它（如名称所示）适用于Windows。

此外，对于include / lib目录，您应该使用wx-config相应的命令，就像您用于命令行编译一样。

您还可以尝试在trac.wxwidgets.org中查看TobiasT的CMake工作。

找不到wxWidgets（缺少：wxWidgets_FOUND）
