See the website for details.</p> <p>This page describes how you can use MinGW configured as a cross-compiler running under RedHat 6.0 Linux to generate a binary for SQLite that runs under WinNT. Some additional steps (described <a href="#win95">below</a>) are needed to target Win95/98.</p> } proc Code {body} { puts {<blockquote><pre>} regsub -all {&} [string trim $body] {\&} body regsub -all {>} $body {\>} body regsub -all {<} $body {\<} body regsub -all {\(\(\(} $body {<font color="#00671f"><u>} body regsub -all {\)\)\)} $body {</u></font>} body puts $body puts {</pre></blockquote>} } puts { <p>Here are the steps:</p> <ol> <li> <p>Get a copy of the MinGW compiler and all its associated tools that run under Linux. No binary versions of MinGW in this configuration are available for net downloads, as far as I know. You will probably have to download the source code and compile it all yourself. A <a href="mingw.html">separate bulletin</a> describes how this can be done. When you are done, make sure the compiler and all its associated tools are located somewhere on your PATH environment variable. </p> </li> <li> <p> Download the Win32 port of GDBM from <a href="http://www.roth.net/libs/gdbm/"> Roth Consulting</a>. You can FTP a ZIP archive of the sources directly from <a href="ftp://ftp.roth.net/pub/ntperl/gdbm/source/Win32_GDBM_Source.zip"> ftp://ftp.roth.net/pub/ntperl/gdbm/source/Win32_GDBM_Source.zip</a>. </p> </li> <li> <p>Make a directory and unpack the Win32 port of GDBM.</p> <blockquote><pre> mkdir roth cd roth unzip ../Win32_GDBM_Source.zip </pre></blockquote> </li> <li> <p>Manually build the GDBM library as follows:</p> <blockquote><pre> i386-mingw32-gcc -DWIN32=1 -O2 -c *.c i386-mingw32-ar cr libgdbm.a *.o i386-mingw32-ranlib libgdbm.a cd .. </pre></blockquote> </li> <li> <p> Download the SQLite tarball from <a href="http://www.hwaci.com/sw/sqlite/sqlite.tar.gz"> http://www.hwaci.com/sw/sqlite/sqlite.tar.gz</a>. Unpack the tarball and create a separate directory in which to build the executable and library. </p> <blockquote><pre> tar xzf sqlite.tar.gz mkdir sqlite-bld cd sqlite-bld </pre></blockquote> </li> <li> <p> Create a "hints" file that will tell the SQLite configuration script to use the MinGW cross-compiler rather than the native linux compiler. The hints file should looks something like this:</p> <blockquote><pre> cat >mingw.hints <<\END config_TARGET_CC=i386-mingw32-gcc config_TARGET_CFLAGS='-O2' config_TARGET_GDBM_LIBS=../roth/libgdbm.a config_TARGET_GDBM_INC=-I../roth config_TARGET_AR='i386-mingw32-ar cr' config_TARGET_RANLIB=i386-mingw32-ranlib config_TARGET_EXEEXT='.exe' END </pre></blockquote> </li> <li> <p>Configure and build SQLite:</p> <blockquote><pre> ../sqlite/configure --with-hints=./mingw.hints make </pre></blockquote> </li> </ol> <a name="win95"> <h2>Targetting Windows95/98 instead of WindowsNT</h2> <p>A small amount of additional work is needed to get SQLite running under Windows95/98. The first problem is that the LockFile() and UnlockFile() API that the Roth GDBM port uses does not work under Windows95. The easiest workaround is to just disable file locking in the GDBM library. You can do so by appending a few lines of code to the end of one of the GDBM source files and compiling the library using a special command-line option. Replace step (4) above as follows:</p> <ol> <li value="4"><p> Append text to the <b>systems.h</b> source file as follows:</p> <blockquote><pre> cat >>systems.h <<\END #ifdef NO_LOCKS #undef UNLOCK_FILE #define UNLOCK_FILE(x) #undef READLOCK_FILE #define READLOCK_FILE(x) lock_val=0; #undef WRITELOCK_FILE #define WRITELOCK_FILE(x) lock_val=0; #endif END </pre></blockquote> <p>Then manually build the GDBM library with the extra "NO_LOCKS" define as follows:</p> <blockquote><pre> i386-mingw32-gcc -DWIN32=1 -DNO_LOCKS -O2 -c *.c i386-mingw32-ar cr libgdbm.a *.o i386-mingw32-ranlib libgdbm.a cd .. </pre></blockquote> </p></li> </ol> <p>Note that the locking problem has been reported and may actually be fixed in the Roth GDBM distribution by the time you read this. You should probably check before you make the above changes.</p> <p>The above is all you have to do to get SQLite to work on Windows95. But one more step is required to get it to work <i>well</i>. It turns out that SQLite make heavy use of <b>malloc()</b> and <b>free()</b> and the implementation of this functions on Windows95 is particular poor. Large database queries will run more than 10 times faster if you substitute a better memory allocator such as the one by <a href="http://g.oswego.edu/dl/html/malloc.html">Doug Lea</a>. A copy of Doug's allocator is included in the <b>contrib</b> directory of the source tree. Speed improvements are also reported on WindowsNT when alternative memory allocators are used, though the speedup is not as dramatic as it is with WIndows95.</p> } puts { <p><hr /></p> <p><a href="index.html"><img src="/goback.jpg" border=0 /> Back to the SQLite Home Page</a> </p> </body></html>} |
