Subject RE: 64-bit build errors
Date Mon, 02 Jan 2006 14:46:26 GMT
 Thanks,
	I will try the CFLAGS="-fPIC" on the APR build. I was using it
on my library build.  Under 32-bit, I have been using:

 ./configure --disable-shared --enable-static  

With this, I am able to statically link in the APR libs to my shared
lib.  I did not need the "-fPIC" flag. I like this method because I can
distribute a single binary library rather than installing and building
APR on each machine I need my library on.  My target is limited to
RedHat Linux and Win32, so it makes deployment a bit easier.


Why is it generally a bad idea to link APR statically into a shared
library ?  What is the preferred method ?  With the static method, I can
precisely control the version of APR that my library uses.  The only
downside I see is my library is larger and my library footprint is
larger.  This is an acceptable tradeoff in my environment.

Daniel

You used -fPIC when building what, your library or APR?  If you want to
link APR statically into a shared library (though this is generally a
pretty bad idea), you need to build APR with -fPIC, e.g. using:

  CFLAGS="-fPIC" ./configure ..
