[ikiwiki] / doc / bugs / post-update_hook_can__39__t_be_compiled_with_tcc.mdwn

Thinking that any c compiler would do the job, I tried to use tcc with ikiwiki, as explicitely allowed by the Debian package dependencies.

I installed `tcc` and `libc6-dev` (for `libcrt1`). The wrapper compilation was OK, but the wrapper fails to run correctly and dies with

    usage: ikiwiki [options] source dest
       ikiwiki --setup configfile

Everything works fine with gcc.

versions: Debian lenny + backports

> Given that the man page for `clearenv` suggests using `environ=NULL`
> if `clearenv` is not available, I would be lerry or using tcc to compile
> stuff, since that could easily lead to a security compromise of code that
> expects that to work. However, I have fixed ikiwiki to use `clearenv`.
