Looking into the two linux systems I have access to, I see

• In one, a group computer to which I have full root access, there is no

/usr/X11 directory, only a /usr/X11R6 directory which contains virtually nothing, only a bin subdirectory containing symlinks to mkfontdir and mkfontscale

• In the other, a lab computer to which I have no root access, I see

neither /usr/X11 nor /usr/X11R6 directories (but they could be hidden from ordinary users).

X11 files are contained in regular /usr/include, /usr/lib, /usr/lib32, /usr/lib64 directories, and thus they are not found through $(X11INCS) and $(X11LIBS). The only necessary stuff when compiling binaries seems to be -lX11 contained in $(X11LIBS).

Probably you can check on your system.

On a plain Mac OS X, there is no X11. At least with some versions and it must be installed by the user. If so, it is placed in /usr/X11/, for example /usr/X11/lib/libX11.dylib. At least on 10.6, i also have /usr/X11R6, but this is only a symlink to /usr/X11.

With the latest patch "./configure --target=osx; make" gives a successful build. Thank you for your patience.

The next step is enabling the extra image file formats. This crashes with undefined symbols, when building the library.

Example after ./configure --target=osx --enable-png

... gcc -m32 -dynamiclib -dylib_install_name,libgrx20X-2.4.9.dylib -o ../lib/macosx/libgrx20X-2.4.9.dylib draw/bitblt.lo ... Undefined symbols: "_png_set_gray_to_rgb", referenced from: _readpng in png2ctx.lo "_png_set_IHDR", referenced from: _writepng in ctx2png.lo

and many more in png2ctx.lo and ctx2png.lo. As with X11, the library and the library path are needed, depending on the installation of libpng.dylib. Example: -L/usr/local/lib and -lpng
