This sometimes causes problems or confusion +to developers. This document should help clear up a few things. + +dnr.c +----- + +We have found a way to work around some bugs in dnr.c that +Apple has never fixed even though we sent in numerous bug reports. +The file tclMacDNR.c simply set's some #pragma's and the includes +the Apple dnr.c file. This should work the problems that many of +you have reported with dnr.c. + +More Files +---------- + +Macintosh Tcl/Tk also uses Jim Luther's very useful package called +More Files. More Files fixes many of the broken or underfunctional +parts of the file system. + +More Files can be found on the MetroWerks CD and Developer CD from +Apple. You can also down load the latest version from: + + ftp://members.aol.com/JumpLong/ + +The package can also be found at the home of Tcl/Tk for the mac: + + ftp://ftp.sunlabs.com/pub/tcl/mac/ + +I used to just link the More Files library in the Tcl projects. +However, this caused problems when libraries wern't matched correctly. +I'm now including the files in the Tcl project directly. This +solves the problem of missmatched libraries - but may not always +compile. + +If you get a compiliation error in MoreFiles you need to contact +Jim Luther. His email address: + + JumpLong@aol.com + +The version of More Files that we use with Tcl/Tk is 1.4.3. Early +version may work as well.. + +Unfortunantly, there is one bug in his library (in 1.4.3). The bug is +in the function FSpGetFullPath found in the file FullPath.c. After +the call to PBGetCatInfoSync you need to change the line: + + if ( result == noErr ) + + to: + + if ( (result == noErr) || (result == fnfErr) ) + + +The latest version of More Files is 1.4.6. Unfortunantly, this +version has a bug that keeps it from working with shared libraries +right out of the box. If you want to use 1.4.6 you can but you will +need to make the following fix: + + In the file "Opimization.h" in the More Files package you + need to remove the line "#pragma internal on". And in the + file "OptimazationEnd.h" you need to remove the line + "#pragma internal reset". + +Note: the version of MoreFile downloaded from the Sun Tcl/Tk site +will have the fix included. (If you want you can send email to +Jim Luther suggesting that he use Tcl for regression testing!) + +Ray Johnson |
