Hi, I hope someone could help me with this. Tried to compile 21.5.8 on cygwin and MSVC 6. Both attempts failed miserably. I am able to build and install 21.4.7, 21.4.8 and 21.5.7. Here are the problems: on cygwin, I configured only with --with-mule=yes This is the sorry end: make[1]: Entering directory `/xemacs/xemacs-21.5.8/src' ./temacs -nd -no-packages -batch -l /c/src/tools/xemacs/xemacs-21.5.8/src/../lis p/update-elc.el ./temacs -nd -no-packages -batch -l /c/src/tools/xemacs/xemacs-21.5.8/src/../lis p/loadup.el dump make[1]: [xemacs] Error 255 (ignored) make[1]: *** [xemacs] Error 1 make[1]: Leaving directory `/xemacs/xemacs-21.5.8/src' make: *** [src] Error 2 Under MSVC the build dies here (again configured with MULE=1): Dumping under the name xemacs rc -d INCLUDE_DUMP -Fo C:\src\tools\xemacs\xemacs-21.5.8\nt\obj\xemacs.res C:\src\tools\xemacs\xemacs-21.5.8\nt\xemacs.rc link.exe ＠C:\DOCUME~1\weiv\LOCALS~1\Temp\nmc01772.

It appears that MSVC build leaves me with a xemacs.exe executable that cannot open any files - all attempts on C-x C-f let me enter the filename and then end with: Finding truename: Unknown error, c:\blah.txt or whatever file I'm trying to open. I'm able to edit and save a file, but I cannot open it. Thanks, Vladimir
