I found the reason of the error: the tcl_platform(os) call returns
"CYGWIN_NT-6.1-WOW64" instead of the expected "windows" string.
Here the patch that SHOULD avoid the error (the code part below starts
around line 67 of ecos-install.tcl):
# ----------------------------------------------------------------------------
# Namespaces. All code and variables in this script are kept in the namespace
# "ecos_install". This is not really necessary for stand-alone operation, but
# if it ever becomes desirable to embed this script in a larger application then
# using a namespace is a lot easier.
#
# As a fringe benefit, all global variables can be declared inside this
# namespace and initialised.
#
namespace eval ecos_install {
# What OS is this?
variable os $tcl_platform(platform)
# "unix" isn't specific enough, so:
if { $os == "unix" } {
set os $tcl_platform(os)
}
# ---------------- begin patch
if {[string match "CYGWIN*" $os]} {
set os "windows"
}
# ---------------- end patch
I wrote SHOULD since I still experience the random error "couldn't
fork child process: resource temporarily unavailable", so I'm not able
to fully test the patch.
Hope that help.
Ciao
Fabrizio
