rtext: How to build

Here is how I build rtext on all the three supported platforms.

Prerequisites:

Tcl (trunk branch) must be in (rtextlocation)/../tcl
Tk (trunk branch) must be in (rtextlocation)/../tk

Then the build and test steps are (for me - you should adapt according to your setup):

--------------------------
-- Windows (VS2022)
--------------------------

set MYTCL="C:\Users\francois\Documents\Development\tcltk-fossil\tcl"
set MYTK="C:\Users\francois\Documents\Development\tcltk-fossil\tk"
set MYTCLTK="C:\Users\francois\Documents\Development\tcltk-fossil\tcltk"

REM set DEBUGRELEASE="none"
set DEBUGRELEASE="symbols"

CALL "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvarsall.bat" x86_amd64

cd C:\Users\francois\Documents\Development\tcltk-fossil\rtext\win

nmake -f makefile.vc TCLDIR=%MYTCL% TKDIR=%MYTK% INSTALLDIR=%MYTCLTK% OPTS=%DEBUGRELEASE% clean
nmake -f makefile.vc TCLDIR=%MYTCL% TKDIR=%MYTK% INSTALLDIR=%MYTCLTK% OPTS=%DEBUGRELEASE%
nmake -f makefile.vc TCLDIR=%MYTCL% TKDIR=%MYTK% INSTALLDIR=%MYTCLTK% OPTS=%DEBUGRELEASE% install

nmake -f makefile.vc INSTALLDIR=%MYTCLTK% OPTS=%DEBUGRELEASE% test TESTFLAGS="-verbose be"


--------------------------
-- Linux
--------------------------

procs=$(getconf _NPROCESSORS_ONLN)
cd ~/Documents/tcltk/fossil/rtext
rm ./configure
autoconf
./configure --enable-symbols
make clean
make -j $procs
make install

make test


--------------------------
-- macOS (XQuartz or aqua)
--------------------------

export CFLAGS="-ObjC"  ; # needed for aqua only
procs=$(getconf _NPROCESSORS_ONLN)
cd ~/Documents/tcltk/fossil/rtext
rm ./configure
autoconf
./configure --enable-symbols
make clean
make -j $procs
make install

make test  ; # or (XQuartz):  DISPLAY=:0  make test


---------------------------------
-- Basic instanciation from tclsh
---------------------------------

package require Tk
package require rtext
rtext::build-info
::tk::text .lt    ; # legacy text widget
text .rt          ; # revised text widget
