Hello xemacs team, I found the part for making vsim cygwin aware. If i use menu VHLD->compile->Compiler Buffer I get the error: $ cd /cygdrive/d/electronic/Projects/LA/mxe/ $ vcom -93 -work work /cygdrive/d/electronic/Projects/LA/source/vhdl/num_type.vhd Model Technology ModelSim XE III vcom 6.0a Compiler 2004.11 Nov 10 2004 ** Error: (vcom-7) Failed to open design unit file "/cygdrive/d/electronic/Projects/LA/source/vhdl/num_type.vhd" in read mode. No such file or directory. (errno = ENOENT) Compilation exited abnormally with code 2 at Fri Sep 30 14:23:08 The last line attached is hopefully the solution for this (the use of cygpath -d $path to convert paths). Can you extend the vhld-mode's vhdl-compile() function with this one? I guess, you must use new variables like file-name-prefix/-postfix to aware the compatibility with non cygwin environments. Personaly I haven't any (emacs) lisp knowlegde unfortunally.
