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

[Christian JULLIEN]

Hi Grischka,

Please read carefully!

The issue is definitely not with Cygwin/Mingwin gcc. Cygwin used to work perfectly with your .bat script.

The issue is with new default value for :

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

Which prevents tcc boostrapt unless you set CONFIG_TCCDIR in config.h for example to "." as it was before.

You can change your .bat script with either:

echo>>..\config.h #define CONFIG_TCCDIR "%CD:\=/%"

‍for an absolute value or

echo>>..\config.h #define CONFIG_TCCDIR "."

For a relative value.

C.
