I have perl/tk installed and working. I tried using c++/tk and had to change the #include path in the headers to find the tk.h and tcl.h. I tried compiling a simple c++ program with g++ to test that the headers are correct. the line i type at console is:

g++ test.c cpptk.cc cpptkbase.cc -o test.bin

I fixed all previous errors, except for the following.

I checked the error in the file cpptkbase.cpp, but nothing is wrong. i'm using ubuntu 10.10 and the files i downloaded is:

cpptk.cc cpptk.h cpptkbase.cc cpptkbase.h cpptkoptions.x cpptkconstants.x

i'm stumped as to how to correct this error.

cpptkbase.cc : Timestamp = February 2006.

May be use an older g++ : 'g++-3.3 test.c cpptk.cc cpptkbase.cc -o test.bin

Suggest : Add 'hardy' to /etc/apt/sources.list, and do :
sudo apt-get update && sudo apt-get install g++-3.3

i tried your suggestion, but still get the same errors. it says something about the forward declaration, but it looks fine to me. i'm still stumped by what it could be.

Yesterday I have compiled (gcc 4.5.3 ) my test-example with success by the next code:

g++ example.cpp /downloads/cpptk-1.0.2/cpptk.cc /downloads/cpptk-1.0.2/base/cpptkbase.cc -ltcl -ltk -pthread -I/downloads/cpptk-1.0.2/ -o myprog

before it, i patched the line:212 of cpptkbase.cc: catch (exception const &e) -> catch (std::exception const &e)
all examples from cpptk were compiled with success too.

Tk is nice/
