[Tinycc-devel] tinycc 0.9.25 x86_64 on Fedora 12

[Aharon Robbins]

Hi. I built tinycc on my x86_64 Fedora 12 system. Here's a report.

1. Below is a patch that was necessary to get it to find the libraries;
   something should be done with configuring etc. to handle this. My patch
   is definitely quick and dirty.

2. When built, my program could not find some of the string functions,
   such as strlen, strcmp, strncmp and strcpy. I put in replacement versions,
   but that's not a scalable solution. Any idea what's not working?

3. I have a static table with some function pointers to static functions.
   This compiles, but the table values are NULL. Any idea why?

4. The external variable `char **environ' was accessable, but initialized
   to NULL. I had to use the (really old style) three argument version of
   main to get access to the environment and then initalize environ from
   within main.  Any idea why?

I am overall quite impressed; the compiler is blazingly fast, which is
quite refreshing when one normally uses GCC.

Thanks,
