It may be advisable to reply directly on the bug tracker instead of replying to emails because the emails are not recorded to the bug report.

The mentioned cmake files are filed in report #1445. We didn't see a strong need to add these to HM yet because the existing makefiles seem to work fine for HM and cmake is another tool that needs to be installed on the target machine.

In general you can use the Linux build process.

Make sure, you have make and g++ installed.

What I'm seeing with cygwin is

 error: -fPIC ignored for target (all code is position independent) [-Werror]

This can easily fixed by removing the -fPIC parameter from build/linux/common/makefile.base
(twice)

The parameter is a default in Cygwin anyway, which causes a warning. With our settings, all warnings are considered as errors (-Werror), so also removing -Werror would help (as mention in the email thread).

I have removed the -fPIC parameter in r4854.

It does not have any effect for HM, because we don't link dynamically:

​https://gcc.gnu.org/onlinedocs/gcc/Code-Gen-Options.html

-fPIC
    If supported for the target machine, emit position-independent code, 
    suitable for dynamic linking and avoiding any limit on the size of 
    the global offset table. This option makes a difference on AArch64,
    m68k, PowerPC and SPARC.

    Position-independent code requires special support, and therefore 
    works only on certain machines.

    When this flag is set, the macros __pic__ and __PIC__ are defined 
    to 2. 

The problem were solved when I remove the -fPIC and -Werror parameter from the makefile.base.
Everything is working fine now.
Thanks to all.
