[jbr] - 2012-03-20 I have been trying to compile the [tcom] extensions with no success. It should be understood that I have little or no experience on Windows. I started by checking out the source from a git repository here https://github.com/pukkaone/tcom.git. I installed ActiveTcl, CMake and Visual C++ 2008 as instructed by the BUILD_INSTRUCTIONS.md. When trying to build the project created by cmake, the git sources seem to be missing "version.h" and "buildNumber.h". I stole these files from the 3.9 zip file on [Chin Huang]'s site. I had to add an include directive to the *.rc files for "buildNumber.h". The project then builds without erros but the package does not work. A test script hangs at "package require tcom". Also, the dll files are very large and not comparable to the distributed binaries. ====== john@home : ls -l total 2072 -rw-r--r-- 1 john john 114 Mar 19 19:29 pkgIndex.tcl -rw-r--r-- 1 john john 562176 Mar 19 19:29 tcom.dll -rw-r--r-- 1 john john 4220 Mar 19 19:29 tcom.tcl -rw-r--r-- 1 john john 244736 Mar 19 19:29 tcominproc.dll -rw-r--r-- 1 john john 236032 Mar 19 19:29 tcomlocal.exe ====== Any help would be appreciated. Thanks, John [PT]: MSVC discriminates between debug builds and release builds. The published files are likely a release build so optimized and stripped and linked to the optimised version of the C runtime. Debug builds run significantly slower but provide more information about errors and the runtime performs bounds checking on memory accesses and so on. In the released version of tcom (without CMake) you'd open the solution file, select the release build and possibly adjust the path to Tcl in the project settings for Preprocessor includes and the Linker library imports. For CMake - you will have to fork and fix this yourself or contact the owner of that repository. These files (version.h and buildNumber.h) are not part of the normal tcom sources. [jbr] - The git repository that I cloned appears to be the latest source for tcom. Can you suggest an alternative source distribution? Thanks.
