Bitcoin / Litecoin Compiling Error

[NoahBuscher]

Hiya! I am working on a new dummy coin for testing and when I try and compile the Windows client I keep getting the error:

Code:

../mingw32/bin/ld.exe: cannot find -ldb_cxx

I have the Berkeley DB installed at C:\deps\db and I compiled it with:

Code:

  ../dist/configure --disable-replication --enable-mingw --enable-cxx

I am following the amazing tutorial for creating a clone over here, but I also tried the instructions on StackOverflow and the error was the same. If it helps, I'm running Windows 8 x64 with MinGW 20120426. All the versions for the dependencies are the same as the ones on the tutorial linked to above.

I checked in the C:\deps\db\build_unix and sure enough there is a file called db_cxx.h, but no library to be found.

I'm not trying to compile the non-Qt version, so no need to worry about that. Thanks so much for any replies!

I am stuck at the same point... I have a working wallet qt for mac and linux, but no windows yet.

Did Berkeley DB build correctly? If you can't find the library file, the linker sure won't be able to either. If you know where it is, add an -L/path/to/db_cxx.lib to the LDFLAGS environment variable.

Whenever I build an altcoin daemon in Linux, I have to add an -I/path/to/db_cxx.h to my CFLAGS and CXXFLAGS. Libraries work the same way, but with -L and LDFLAGS.

You are correct, I realized a couple of hours ago that the DB build had not completed when I thought it did. On to the next obstacle...
