How to compile Berkeley DB 5.3.28 for MXE cross-compiler?

Has anybody a solution for building Berkeley DB for MXE's cross-compile environment?

When I run my build script:

 #!/bin/bash

 MXE_PATH=/path/to/mxe
 
 db=db-5.3.28

 rm -rf ./$db/build_mxe
 mkdir -p ./$db/build_mxe
 cd ./$db/build_mxe
 
 sed -i "s/WinIoCtl.h/winioctl.h/g" ../src/dbinc/win_db.h

 CC=$MXE_PATH/usr/bin/i686-w64-mingw32.static-gcc \
 CXX=$MXE_PATH/usr/bin/i686-w64-mingw32.static-g++ \

 ../dist/configure \
     --build=x86_64-pc-linux-gnu \
     --host=x86 \
     --disable-replication \
     --enable-cxx \
     --enable-mingw \
     --prefix=/path/to/dev/mingw_db

  make -j6; make -j6 install

The compiler warns of direct.h missing:

../src/dbinc/win_db.h:21:20: fatal error: direct.h: No such file or directory compilation terminated.

direct.h and all dependent files exist in mxe/usr/i686-w64-mingw32.static/include directory

So how to force the compiler to use these files ?

Solution

  • I've improved upon my build script and solved my question:

    I had to fix the original script which then perfected the build.

    The correct syntax goes as follows:

    #!/bin/bash

## Path to MXE source
 MXE_PATH=/home/demon/dev/mxe
## Path for mingw headers
 MXE_INCLUDE=$MXE_PATH/usr/i686-w64-mingw32.static/include

## Path to db source
 db=db-6.1.26

## Make a clean working tree and Create working DIR 
## You can also use `make distclean` within build_mxe to start fresh
 
 rm -rf ./$db/build_mxe
 mkdir -p ./$db/build_mxe

## Enter working directory
 cd ./$db/build_mxe

## Correct naming of header file
 sed -i "s/WinIoCtl.h/winioctl.h/g" ../src/dbinc/win_db.h


## Define CC and C++ compiler & user level commands
export CC=$MXE_PATH/usr/bin/i686-w64-mingw32.static-gcc
export CXX=$MXE_PATH/usr/bin/i686-w64-mingw32.static-g++
export AR=$MXE_PATH/usr/bin/i686-w64-mingw32.static-ar
export STRIP=$MXE_PATH/usr/bin/i686-w64-mingw32.static-strip
export RANLIB=$MXE_PATH/usr/bin/i686-w64-mingw32.static-ranlib

### Find mingw headers in non-standard directory
export CPPFLAGS=-I$MXE_INCLUDE


## Configure the build
 ../dist/configure \
     --build=x86_64-pc-linux-gnu \
     --host=x86 \
     --disable-replication \
     --enable-cxx \
     --enable-mingw \
     --program-transform-name='s,.exe,,;s,\(.*\),\1.exe,' \
     --prefix=/home/demon/dev/mxe_db \
     --exec-prefix=/home/demon/dev/mxe_db

## Build DB and install it
 make -j(nproc); make -j(nproc) install

    The corrected issues:

    That did the trick !
