无法使用娜娜图书馆 [英] Cannot use nana library

问题描述

我尝试将Nana库与Code :: Block IDE结合使用。我进行了所有设置，例如此处

I try to use Nana library with Code::Block IDE. I made all settings like here

并添加-std = C ++ 11标志和Boost包含路径，但会在构建时显示下一个错误：

and add -std=C++11 flag and Boost include path but it's print next error on building:

nana / include / nana / paint / graphics.hpp | 143 |错误： unsigned int nana :: paint :: graphics :: bidi_string（const nana :: point& ;, const char *，std :: size_t）'不能重载|

nana / include / nana / paint / graphics.hpp | 142 |错误：
与'unsigned int nana :: paint :: graphics :: bidi_string（const nana :: point& ;, const char_t *，std :: size_t）'|

nana/include/nana/paint/graphics.hpp|143|error: ‘unsigned int nana::paint::graphics::bidi_string(const nana::point&, const char*, std::size_t)’ cannot be overloaded|
nana/include/nana/paint/graphics.hpp|142|error: with ‘unsigned int nana::paint::graphics::bidi_string(const nana::point&, const char_t*, std::size_t)’|

我只开始研究C ++ 11标准和Nana GUI库，无法理解这些错误。

I only start study C++ 11 standart and Nana GUI library and cannot understand these bugs.

推荐答案

我遇到了同样的问题。
为了解决问题，我看了 nana 如何通过用<$编译 nana 来解决这个问题。 c $ c> make VERBOSE = 1 ，
并从中获取定义。

I faced the same problem. To solve problem I look at how nana it self deal with this problem by compiling nana with make VERBOSE=1, and take defines from it.

以编译后的示例为例：

#include<nana/gui.hpp>

int main()
{
     using namespace nana;
     form fm;
     drawing{fm}.draw([](paint::graphics& graph){
         graph.string({10, 10}, L"Hello, world!", colors::red);
     });
     fm.events().click(API::exit);
     fm.show();
     exec();
}

来自nana网站（ http://nanapro.org/en-us/ ）我使用以下命令行：

from nana site(http://nanapro.org/en-us/) I use such command line:

g++ -DNANA_ENABLE_PNG -DNANA_LIBPNG -DNANA_LINUX -DNANA_UNICODE \
-DNANA_X11 -DPLATFORM_SPEC_HPP="<nana/detail/linux_X11/platform_spec.hpp>" \
-DSTD_CODECVT_NOT_SUPPORTED -std=c++11 -I nana/include/ \
test.cpp build/libnana.a -lX11 -lXft -lpthread -lpng
