ld.exe: cannot find -lstrmbase

Question

I am getting a the following error in code blocks using gnu gcc compiler, when I try to compile the code I get these errors:

c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe: cannot find-                                          lstrmbase
c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe: cannot find -lz
collect2: ld returned 1 exit status
Process terminated with status 1 (0 minutes, 21 seconds)
2 errors, 0 warnings (0 minutes, 21 seconds)

Answer 1

1. First, make sure you have strmbase.lib (or libstrmbase.lib) and z.lib (libz.lib) in your mingw lib directory (it should be "c:/mingw/gcc/mingw32/4.6.2/" in your case).

2. Second, if they do exist, try to add "c:/mingw/gcc/mingw32/4.6.2/" to your library search path.

   There may be GUI option like "LIBRARY PATH" for that, although I don't know about code blocks.

   Alternatively, you can pass an option to gcc "-L c:/mingw/gcc/mingw32/4.6.2/" (It must be before "-l..." flags)

EDIT:

1. z.lib is zlib. You can build it using your gcc or download prebuilt binary from MinGW web-site (should be inside MinGW -> Extension).

2. strmbase.lib is from DirectShow Samples. You can get its source code by installing Windows SDK. There might be someone distributing prebuit binary for MinGW.
