Re: [Tinycc-devel] build-tcc.bat is broken since recent changes

[Christian JULLIEN]

Grischka,

Thank you for your efforts to convince me (I'm still not).

Of course I know that build-tcc.bat was supposed to work with mingw. This is how I started to build tcc for Windows long ago.

I also know that until you very recently changed

 # define CONFIG_TCCDIR "."

to

‍

 # define CONFIG_TCCDIR "/usr/local/lib/tcc"

Standard Cygwin+gcc install was ALSO able to bootstrap a fully working tcc.exe for Windows.

I still don't understand the reasons of this change. IMHO "." , i.e. relative path is far better than "/usr/local/lib/tcc" which supposes that lib has already installed in this path which is btw not very Windows friendly.

If I locally change back to  # define CONFIG_TCCDIR "."

tcc.exe bootstraps again with Cygwin/gcc that why I thing it's a regression.

Now I give up, I have the trick to make Makefile working again which is my main goal.

Even nothing is perfect, I would like to thank you for the time you spend on this project. I'll no more bother you with this topic.

C.
