Comments on building tcl/tk for AMD64 with the MS SDK compiler ============================================================== I did have to build tcl/tk manually. First, I had to build the nmakehlp.exe helper utility manually by executing cl nmakehlp.c /link bufferoverflowU.lib in both the tcl8.4.12\win and tk8.4.12\win directories. Second, the AMD64 compiler refuses to compile the file tcl8.4.12\generic\tclExecute.c because it insists on using intrinsics for the 'ceil' and 'floor' functions: ..\generic\tclExecute.c(394) : error C2099: initializer is not a constant ..\generic\tclExecute.c(398) : error C2099: initializer is not a constant I did comment out these lines; an alternative would have been to use the /Oi- compiler flag to disable the intrinsic functions. The commands then used were these: svn export http://svn.python.org/projects/external/tcl8.4.12 cd tcl8.4.12\win REM echo patch the tcl8.4.12\generic\tclExecute.c file pause REM cl nmakehlp.c /link bufferoverflowU.lib nmake -f makefile.vc MACHINE=AMD64 nmake -f makefile.vc INSTALLDIR=..\..\tcltk install cd ..\.. svn export http://svn.python.org/projects/external/tk8.4.12 cd tk8.4.12\win cl nmakehlp.c /link bufferoverflowU.lib nmake -f makefile.vc TCLDIR=..\..\tcl8.4.12 MACHINE=AMD64 nmake -f makefile.vc TCLDIR=..\..\tcl8.4.12 INSTALLDIR=..\..\tcltk install cd ..\..
