Using Wt with Visual Studio 2013

Added by Barış Meriç over 8 years ago

Hi,

I'm trying to use Wt html->pdf feature with Visual Studio 2013 but i get linker errors.

I downladed pre-built binaries for VS2013, defined HPDF_DLL, set include/lib folders for project and compiled this snippet;

#include <hpdf.h>
#include <Wt/Render/WPdfRenderer>

namespace {
    void __stdcall error_handler(HPDF_STATUS error_no, HPDF_STATUS detail_no,
        void *user_data) {
        fprintf(stderr, "libharu error: error_no=%04X, detail_no=%d\n",
            (unsigned int)error_no, (int)detail_no);
    }
}
using namespace Wt;

int  main() {
    HPDF_Doc pdf = HPDF_New(error_handler, 0);

    HPDF_Page page = HPDF_AddPage(pdf);
    HPDF_Page_SetSize(page, HPDF_PAGE_SIZE_A4, HPDF_PAGE_PORTRAIT);
    Render::WPdfRenderer renderer(pdf, page);
    renderer.setMargin(2.54);
    renderer.setDpi(96);
    renderer.render("<p style=\"background-color: #c11\">Hello, world !</p>");
    HPDF_SaveToFile(pdf, "hello.pdf");
    HPDF_Free(pdf);
}

But i get "LNK2019: unresolved external symbol "LNK2019: unresolved external symbol "_declspec(dllimport) public:thiscall Wt::Render::WPdfRenderer::WPdfRenderer(void *,void*)\" (imp??0WPdfRendererRender@Wt@QAEPAX0Z) referenced in function _main" error.

I'm linking these libs;

  • libhpdfd.lib
  • wtd.lib
  • wtdbod.lib
  • wthttpd.lib
  • wtisapid.lib
  • wttestd.lib

Is it a link order issue or am i missing something?

Hey Baris,

This is likely a misbuild of the Wt binary. Can you file a bug report for this and assign it to me?

Thank you,

Wim.

Was there ever a resolution or workaround on this? I'm having this same behavior using the most recent stable build.

Hey Neal,

If you build the binaries yourself, you will not have this problem.

I have the wt binaries v3.3.6 and the same linker Problem (use with VS 2015), how can i solve this without generating own wt binaries?
