compiling problems with VC++ 6

[shisha]

Hi All,

I have been having problems compiling OpenSees 1.5.2 using VC++ 6.0.

The error messages go like this:

Error executing cl.exe.

openSees.exe - 4 error(s), 0 warning(s)

Please suggest ideas to overcome the problem.

the problem is tcl/tk .. they have tightened up their api betwen versions 8.3 and 8.4
.. a lot of procedures now take const char * instead of char * .. as we have developers
trying to compile with both versions we have defined TCL_Char in OPS_Globals.h ..
if you look at the OpenSees files that call Tcl routines you will see TCL_Char all over the place .. by default it is char, if the macro definition _TCL84 exists it is const char .. the _TCL84 if required, is placed in the C++ preprocessor settings in the projects .. if you still have problems, i will be updating the vc6.0 project later today so that it compiles with tcl8.4.6 and the latest code in the repository and you can start with the new project and then add your files .. you will be able to obtain it from cvs
