Here I am again. I have been trying to compile OpenDBX with both of them: Cygwin and MinGW. As I have already told you before, with cygwin openDBX compiles perfectly (although I cannot see the dll from FFI), but I had some problems with MinGW. These problems are because OpenDBX does not use any cross-platform socket library wrapper but use native Unix socket libraries. So, I cannot compile this with MinGW. I could, but I have to do this: <br>
<br>Anyway, suppose I cannot use MinGW or imagine MinGW doesn't exist, can I use cygwin with FFI? I mean, can I compile something with cygwin so that FFI can use is? If so, how can I do this? I ask because I know cygwin applications must be distributed with a cygwin dll.<br>
<br>I have this:<br><br>- OpenDBX library -> c:\mariano\opendbx-1.3.10\<br>- Cygwin -> c:\cygwin\<br>- MySQL -> c:\MySQL\<br>- Postgres -> c:\PostgreSQL\<br>- PATH variable: .....;c:\msys\1.0\bin\;c:\cygwin\bin\;C:\MySQL\bin<br>
<br><br>After compiling, I have in c:\cygwin\usr\local\lib\ these files: libopendbx.a, libopendbx.a.dll, <a href="http://libopendbx.la">libopendbx.la</a>, libopendbxplus.a, libopendbxplus.a.dll and <a href="http://libopendbxplus.la">libopendbxplus.la</a>. <br>
There are also, theese folders: c:\cygwin\usr\local\lib\opendbx\ with these files: cygpgsqlbackend-1.dll, libpgsqlbackend.a, <a href="http://libpgsqlbackend.la">libpgsqlbackend.la</a> and libpgsqlbackend.a.dll<br>c:\cygwin\usr\local\lib\pkgconfig\ with file: opendbx.pc<br>
<br>Now, what should I do with this? is this right?<br><br>very thanks,<br><br>Mariano<br><br><div class="gmail_quote">On Fri, Jun 20, 2008 at 5:20 PM, Mariano Martinez Peck <<a href="mailto:marianopeck@gmail.com">marianopeck@gmail.com</a>> wrote:<br>

</div></div>why not just build a .dll with mingw tools?</blockquote></div></div><div><br><br>Igor: Thanks a lot for the answer. Norbert (openDBX author) tell me that openDBX can be compiled with both of them: cygwin and winGW. As I know cygwin I tried with it and not with winGW.<br>
<br>Why do you think I could use MinGW? which are the difference between them (MinGW and Cygwin) ?</div></div></blockquote></div></div><div><br><a href="http://en.wikipedia.org/wiki/MinGW#Comparison_with_Cygwin" target="_blank">http://en.wikipedia.org/wiki/MinGW#Comparison_with_Cygwin</a><br>
