mingw-w64 builds anyone?

[Carl Kleffner]

Hi!

as the yeppp library is written in C++ a usage within mingw-w64 (windows) requires the dll to be compiled by minwg-w64.
Is there any advice how to accompish this on Windows?

With best Regards

Hi Carl,

Compilation of Yeppp! with mingw is not supported and there are no plans to enable such builds. However, I believe that it is possible to use Yeppp! with mingw (although I didn't try it myself). The library does not expose any C++ features in its interface, so you could use it just as any other C library (e.g. WinAPI DLLs). Yeppp! also does not have a dependency on Microsoft CRT as it uses its own tiny CRT library.

Regards,
Marat

Hi Carl,

I just tried to use Yeppp! with mingw64, following the guide from MinGW wiki (http://www.mingw.org/wiki/MSVC_and_MinGW_DLLs), and it works flawlessly. After I converted the COFF import library ($YEPROOT/binaries/windows/amd64/yeppp.lib) to GNU format (libyeppp.a) gcc/mingw64 linked to it without any problems, and the produced binaries are fully operational.

Below is the complete sequence of commands I used

cd "%YEPROOT%"

SetVars.bat

cd binaries/windows/amd64

reimp yeppp.lib

cd ../../..

cd examples/c

gcc -o binaries/CpuInfo.exe sources/CpuInfo.c -I "%YEPROOT%/library/headers" -L "%YEPROOT%/binaries/windows/amd64" -lyeppp

binaries\CpuInfo.exe

Indeed,

examples runs like a charm (on Penryn):

Polynomial.exe
Naive implementation:
        Time = 4.093182 secs
        Performance = 0.409882 GFLOPS
Yeppp! implementation:
        Time = 0.251865 secs
        Performance = 6.661204 GFLOPS
Max error:   0.000%

Many thanks

Carl
