Re: [Tinycc-devel] Push reproducible builds script? (for windows)

[Christian Jullien]

Grischka,
It's difficult to give advice. It entirely depends on the C toolchain you
already have on your machine (or you're ready to install).
My **personal** choice is of course Cygwin/Makefile because I have Cygwin
installed with gcc for Cygwin and this Makefile, thanks to bash, lets me run
tests for x86 and x64 with one command.
Someone accustomed to Windows will prefer VC++.
I admit a "How to build" guide would be welcome because it's probably hard
for a noob to bootstrap a working tcc on Windows.

Not in principle.

Except I'd appreciate some concept to advise users which method to build tcc
on or for windows to use best in what situation.

We do support:
* msys with the normal ./configure && make && make install
* also cygwin with ./configure --cross-prefix=mingw32- && make && make
install
* also cygwin with Jullien's Makefile from win32
* just mingw's gcc or msvc's cl with build-tcc.bat from win32, including
   option to install, no sh-shell required.
* maybe your reproducible build script, with again its own advantages as
   well as drawbacks.

What is your recommendation?  And how (if any) can we make sure that it will
reach users?
