Re: [Dev-C++] errors when linking to a .lib

[Alexander S. <a.s...@qu...>]

Joshua,

The reimp tool does exactly what you need. You get it as part of the=20
"MinGW Utilities".
Download it from here:=20
http://prdownloads.sf.net/mingw/mingw-utils-0.3.tar.gz?download

it will turn a XXX.lib to a libXXX.a file, ready to be used with Dev-Cpp.=
