wxHTTPEngine.DevPak don't build with wxdevcpp 4.7.1 Topic is solved

[starra]

wxHTTPEngine example don't build with wxdevcpp 7.4.1.
in file httpbuilder.h in row 45 i replace

Code: Select all

wxProxySettings() { m_bRequiresAuth = 0; m_bUseProxy = 0; m_nProxyPort = 0; m_strProxyExceptionsDelim = ","; }

with

Code: Select all

wxProxySettings() { m_bRequiresAuth = 0; m_bUseProxy = 0; m_nProxyPort = 0; m_strProxyExceptionsDelim = [b]wxT(",")[/b]; }

in httpengine.dev i have replace -lwxmsw28 -lwxmsw28_gl -lwxregex with -lwxmsw28u -lwxmsw28u_gl -lwxregexu
and add _UNICODE in preprocessor definition.

with this modify if i build the log compile is

It looks like the wxHTTPEngine DevPak wasn't built with Unicode support. So simply adding the _UNICODE flag and using the wxT() wrapper isn't enough (although that's needed too).

You need to download the actual source code for wxHTTPEngine and create your own wxhttpengine.a (I think the makefile will probably call it wxhttpengineu.a). It's a bit tricky, but definitely a good learning experience.

To start, you'll need to download the wxWidgets source (http://sourceforge.net/projects/wxwindo ... urce=files). Then, from the Windows command line you'll need to change the directory to c:\wxWIdgets-2.8.12\build\msw.

Now type the following 2 commands:

Code: Select all

set path=C:\Progra~1\dev-cpp\bin;%path%
mingw32-make -f makefile.gcc UNICODE=1 MONOLITHIC=1 BUILD=release

This assumes that your wxDev-C++ is installed in c:\Program Files\dev-cpp. The build will take about 30-60 minutes so have your favorite beverage handy.

Now download the wxhttpengine.zip file and unzip it (http://sourceforge.net/projects/wxcode/ ... p/download).

Then from the Windows command line change the directory to the wxhttpengine/build directory. Then, type the following two commands:

Code: Select all

set path=C:\Progra~1\dev-cpp\bin;%path%
mingw32-make -f makefile.gcc UNICODE=1 MONOLITHIC=1 BUILD=release

Then copy the compiled library from wxhttpengine\lib into your c:\Program Files\Dev-Cpp\lib directory.

That file should have unicode support and will correctly link.

ok with the new library with unicode support linking correctly.
There is a problem in component.
Tn example exe don't load a page of url select.
Is possible that is a unicode problem of url passed?
For build wxhttpengineu.a i have replate "" string with wxT("")

I'm not sure url's can handle Unicode strings. However, you might want to post this question on the C++ developer's section of this forum. They are more knowledgeable about such things.
