Re: [Dclib-devel] dlib c++ on mac os x

[Davis K. <dav...@us...>]

All those errors in the dlib/test/makefile are dependency lines added in by
the makedepend program.  So you can type make dep and it will remake them on
OS X assuming you have makedep installed and it is in your path.   But it
has been my experience with OS X that a lot of the unix utilities like
makedepend either aren't installed by default or aren't in your path.  So
you might have to address that.  But you can just remove all the lines below
the # DO NOT DELETE and it will build fine.

You can also use cmake (www.cmake.org) to build the test program and in fact
that is probably the easiest solution.


As for the example programs you have to compile with some command line
statement like g++ example.cpp /source/dlib/all/source.cpp -I /source -l X11

(That is a capitol -i and then a lower case -l)

You might also have to tell it where to find the X11 development libraries
if the compiler can't find them automatically.  They are usually somewhere
like

/Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/


Or if you aren't doing any X11 GUI stuff then you can #define
DLIB_NO_GUI_SUPPORT and then you won't have to worry about linking to X11.


Hope that helps,
Davis
