@ -35,7 +35,19 @@ When your Tcl/Tk libraries are compiled with "pthread support",
|
|||
Ruby/Tk may cause "Hang-up" or "Segmentation Fault" frequently.
|
||||
If you have such a trouble, please try to use the '--enable-pthread'
|
||||
option of the 'configure' command and re-compile Ruby sources.
|
||||
It may help you to avoid this trouble.
|
||||
It may help you to avoid this trouble. The following configure
|
||||
options may be useful.
|
||||
|
||||
--enable-tcl-thread/--disable-tcl-thread
|
||||
--with-tclConfig-file=<path of 'tclConfig.sh'>
|
||||
|
||||
It is not need that 'tclConfig.sh' is a normal Tcl/Tk's tclConfig.sh.
|
||||
But the file is expected to include the line "TCL_THREADS=0" or "...=1".
|
||||
When no "TCL_THREADS=?" line, if Tcl version is 7.x or 8.0 which is
|
||||
given by "TCL_MAJOR_VERSION=?" line and "TCL_MINOR_VERSION=?" line,
|
||||
then --disable-tcl-thread is expected. Else, ignore the 'tclConfig.sh'.
|
||||
If --enable-tcl-thread or --disable-tcl-thread option is given, then
|
||||
--with-tclConfig-file option is ignored.
