I've been working on setting up the proper environment to compile litecoin, and have been following the instructions from this:


2.2 Berkeley DB: http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz

We'll use version 4.8 to preserve binary wallet compatibility.

From a MinGW shell unpack the source archive, configure, edit line 113 of db.h then make:


cd /c/deps/

tar xvfz db-4.8.30.NC.tar.gz

cd db-4.8.30.NC/build_unix

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

after configuring make sure to edit your build_unix/db.h by replacing line 113:


typedef pthread_t db_threadid_t;



typedef u_int32_t db_threadid_t;

I was all set to do it, but this happened: The build_unix folder is empty

I've tried getting db-4.8.30.NC from multiple sources, but no luck—the build_unix folder is always empty.

So what's the deal?

  • I just downloaded Berkeley DB from the link and had no problems. The db-4.8.30NC.tar.gz is 21.7MB. Is this the size of your file? Dec 14 '13 at 22:07
  • I have no problem downloading the file; can you tell me what's inside your build_unix directory? I only have an .IGNORE_ME file. Dec 14 '13 at 22:17
  • There are 793 files, one of which is .IGNORE_ME. There is also a .libs subdirectory. Sounds like your tarball wasn't unpacked correctly or it was truncated. Dec 14 '13 at 22:58
  • Can I have your link? I tried both mingw and 7zip to open it. I tried the windows zip viewer for a zip version. Dec 14 '13 at 23:56
  • I mislead you because I have already built Berkely DB. I went back and looked at the .tar.gz file again and it does contain just the .IGNORE_ME file. You just need to run the configure and make commands to create all of the files in the directory. Dec 15 '13 at 1:07

The build_unix directory contains just the .IGNORE_ME file in the distribution. The directory is populated by the make command.

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

You do not need to edit db.h in the latest distribution since they have already corrected the typedef.

  • ../dist/configure --enable-cxx make this will also do Feb 13 '14 at 4:18
  • im trying to build this on windows, i dont see a configure file. can someone point out

  • I can't believe I missed this answer. I'll see if I still have that stuff on my laptop, maybe I can get it going when I have time! Jun 30 '14 at 1:53
