[Critcl] is in the process of being updated, with new features and a revised build mechanism   ''(as of what date?)''

Amongst the changes 
   * Critcl now builds using a more traditional "gcc -c" step for each source file, followed by a "gcc -shared" step for linking a shared library
   * the critcl::cflags procedure can be used to specify compiler flags
   * the critcl::ldflags procedure can be used to specify linker flags
   * the critcl::framework" procedure for specifying frameworks to use under [MacOS X] 
   * the critcl::clean_cache procedure and "critcl -clean" command are used to clean (i.e. empty) the Critcl cache
   * the critcl::debug command can be used to specify that debugging is enabled - either "memory" and/or "symbols" 
   * the "bytearray" or "rawchar" types can be used as arguments and return values to critcl::cproc
   * the "int*", "float*" and "double*" types can be used as arguments and return values to critcl::cproc
   * improved cross-compiler support when using mingwin
   * all extensions are now built "thread enabled"
 
In addition, the compiler and platform specific commands are now stored in a configuration file. This will make it easier to support new platforms and toolchains. For example, 
   #   Configuration file for the compiler toolchain
   
   # some defaults - you can override these in the platform specific section
   # but shouldn't need to for gcc or typical *nix toolchains
   
   compile         gcc -c
   link            gcc -shared
   preproc         gcc -dM -E
   tclstubs        -DUSE_TCL_STUBS
   tkstubs         -DUSE_TK_STUBS
   debug_memory    -DTCL_MEM_DEBUG
   debug_symbols   -g
   output          -o
   object          .o
   strip           -Wl,-s
   optimize        -O2
   noassert        -DNDEBUG
   threadflags     -DUSE_THREAD_ALLOC=1 -D_REENTRANT=1 -D_THREAD_SAFE=1    \
                   -DHAVE_PTHREAD_ATTR_SETSTACKSIZE=1 -DHAVE_READDIR_R=1   \
                   -DTCL_THREADS=1
                  
   # OSX
   Darwin-ppc  compile   gcc -c
   Darwin-ppc  link      gcc -bundle
   Darwin-ppc  strip     
   
   # Windows
   Windows-x86 compile   gcc -c -nostdlib
   Windows-x86 link      gcc -shared
   
   # Linux - default to current platform
   Linux-*     compile   gcc -c -fPIC
   Linux-*     link      gcc -shared -s
   
   # for cross-compiling using mingw - this will be automatically selected
   # if mingw is recognised
   
   mingw       compile gcc -c -nostdlib
   mingw       link    gcc -shared
   
   # the following will only be selected on the command line
   
   # Linux - force 32 bit compile
   Linux-32    compile   gcc -c -fPIC -m32
   Linux-32    link      gcc -shared -s
   
   # Linux - force 64 bit compile
   Linux-64  compile   gcc -c -fPIC -m64
   Linux-64  link      gcc -shared -s

Until the changes are merged into the main Critcl source you can download the Critcl Starkit from http://www.digitalsmarties.com/pub/critcl.kit. It should be considered as work in progress - there are more changes being implemented, including recognising and handling several 64 bit environments.   

The new Critcl was used in the development of [Muzic]. The changes were implemented by [Steve Landers] and sponsored by [Eolas] Technologies Inc. Thanks are due to [Arjen Markus] for his suggestions and assistance.

**critcl2 & linking with custom library**

'''[milarepa] - 2011-03-22 05:33:19'''

When trying to build cryptkit cith critcl, -lresolv and -lcl_Linux-x86 are passed to GCC.

/usr/lib/libresolv.so is found, but libcl_Lunix-x86.so is not found, despite I have links corretly in place in /usr/lib. (I have tried many places without success ...)

Any idea why this appends ?
