I am not sure how much effort we should make for building U-Boot on Cygwin.
Anyway, other than host programs, I notice file name problem.
Unlike Unix or Linux, on Windows upper/lower cases for file names are not distinguished.
On Cygwin, for example, we cannot do this:
$ mkdir abc $ mkdir ABC mkdir: cannot create directory `ABC': File exists
Right, this is a well know issue.
It causes some problems in U-Boot too.
For example,
$ make mrproper CLEAN SPL rm: cannot remove `SPL': Is a directory Makefile:1278: recipe for target 'clobber' failed make: *** [clobber] Error 1
$ make qong_config Configuring for qong board...
$ make clean CLEAN arch/arm/imx-common rm: cannot remove `arch/arm/imx-common/../../../SPL': Is a directory scripts/Makefile.clean:79: recipe for target '__clean' failed make[1]: *** [__clean] Error 1 Makefile:1256: recipe for target '_clean_arch/arm/imx-common' failed make: *** [_clean_arch/arm/imx-common] Error 2
I notice at least one file name conflict at the top directory.
SPL - image for IMX spl - directory where SPL is built
This commit renames the former to a temporary name.
I guess there is few developers testing U-Boot on Cygwin. If Cygwin support is mandatory, please consider to rename IMX image.
IMHO we have to consider if there will be a high request to build on Cygwin and I prefer to defer this issue. Some developers working before on Cygwin are used to set up a VM on their OS nowadays, reducing the number of people who need a Cygwin environment.
