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

[Stewart, J. <JSt...@ra...>]

I did this just then,
firstly I:
reimp Sigmalib.lib  .. which outputted 3 .obj files and 1 .dll=20
Then I ran
ar rcs libsigma.a *.obj *.dll  .. to create the .a file (as per the =
reimp README instructions)

however i still get the same problems. am I missing a step here?

Now I am linking with the following
gcc.exe -D__DEBUG__ JOSHspares1.o  -o "Simu1testbuild.exe" =
-L"C:/Dev-Cpp/lib" -L"C:/logistics/testbuild1/lib" -L"C:/Dev-Cpp/lib" =
-lkernel32 -luser32 -lgdi32 -lwinspool -lcomdlg32 -ladvapi32 -lshell32 =
-lole32 -loleaut32 -luuid -lodbc32 -lodbccp32 --verbose lib/libsigma.a =20
Reading specs from C:/Dev-Cpp/Bin/../lib/gcc-lib/mingw32/3.2/specs
Configured with: ../gcc/configure --with-gcc --with-gnu-ld --with-gnu-as =
--host=3Dmingw32 --target=3Dmingw32 --prefix=3D/mingw --enable-threads =
--disable-nls --enable-languages=3Df77,c++,objc,ada =
--disable-win32-registry --disable-shared

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.
