Subject: [devel] Building on Windows with MinGW

Hi there,

I've followed the steps outlined here:

https://www.zephyrproject.org/doc/getting_started/installation_win.html

to compile Zephyr on Windows.

The first problem I encountered was that the regex library could not be
found by MinGW's gcc, so I had to add the following to my .bash_profile:

export CPATH="C:/mingw/msys/1.0/include"
export LIBRARY_PATH="C:/mingw/msys/1.0/lib"

Not sure if this is due to the way one installs MinGW, but it was required for
me.

The second problem I see is that no matter how I configure my build (both
manually or adding my own Makefile.toolchain) the build always fails with an
error similar to:

Error processing
'c:/cygwin64/home/cacu/src/nordic/git/cacu/zp/c:\cygwin64\home\cacu\src
\nordic\git\cacu\zp\arch\x86\soc\atom\Kconfig' #123.

Obviously my git repo lives in
c:\cygwin64\home\cacu\src\nordic\git\cacu\zp.

After digging a bit, I found out that win_process_files in zconf.lex.c_shipped
gets the following path when the error occurs:

c:\cygwin64\home\cacu\src\nordic\git\cacu\zp\arch\x86\soc\atom\Kconfig

which obviously does not exist (I see no "Kconfig" file in x86\soc\atom). Since
there is no wildcard, there is no chance that file is going to be found, and
then win_process_files tries a second path by doing:

env = getenv(SRCTREE);
if (env) {
sprintf(fullname, "%s/%s", env, expanded);
}

But that doesn't work either, since it results in a path concatenation.

It is worth mentioning that the folders that *do* contain a Kconfig file, such
as c:\cygwin64\home\cacu\src\nordic\git\cacu\zp\arch\x86\core\Kconfig,
seem to be processed fine.

Any idea on what could be causing this?

Thanks!
