wxWidgets Discussion Forum

I use wxWidgets to write a simple dll project(only export a UI) in MAC+Xcode, but when I compile the project, many error as below:

../include/wx/buffer.h:96: error: parse error before "wxCharBuffer"

../include/wx/buffer.h:96: error: syntax error before '{' token

../include/wx/buffer.h:96: error: parse error before ':' token

…

Could you give me some information about these error
thank you

can you show some code? How did you build and install wxWidgets? Do wx samples build? How did you build your project/makefile?

can you show some code?
----------------------------------------------------------
export.h

int FunTest(int a, int b);
void OpenWnd();

export.cpp

#include <wx/wx.h>
#define EXPORT __attribute__((visibility("default")))
int EXPORT FunTest(int a, int b)
{
return a+b;
}

void EXPORT OpenWnd()
{
wxFrame* pFrame = new wxFrame(...);
pFrame->Show(...);
}
if i only export the FunTest(...), i call it by another application, and it's ok, but when i export OpenWnd(), there will appere many errors.

my code is a simple sample to export a UI for other application, but when comple first line(wx/wx.h),there will apper a lot of error,and by now, the compiler can't comile my any one line code still.

How did you build and install wxWidgets?
I didn't install wxWidgets, but i download it's code and compile successfull

Do wx samples build?
yes, the sample "minimal" comiled and run OK

How did you build your project/makefile?
my project creted by xcode, it is a dynamic link library.

I didn't install wxWidgets, but i download it's code and compile successfull

Well then how did you build it

my project creted by xcode, it is a dynamic link library.

How did you build your xcode project? I suspect you didn't build it properly. try e.g. building your library with a makefile + wx-config, if it works you know your project is incorrect

i create another dynamic project and build successfull, i don't know why? no time to find the answer.
