dgp -- Pushed this commit off the trunk, it breaks the build. Symptoms suggest that a working tcl.h is not found (some broken one is found in stead?) and then compile of Tk fails quickly. Closed-Leaf check-in: f3d8527b user: yorick tags: mistake | |
08:41 | Fix indentation of previous commit, and move one character into quotations in SC_TCL_LINDEX. check-in: 84b404a0 user: yorick tags: buildtools | |
08:30 | Improve ability to find Tcl sources at build time. This introduces a new build-time dependency: A working tclsh version 8.6 or higher must be available in the build environment. check-in: e73977c5 user: yorick tags: buildtools | |
