how to install tcc library without root privileges

[Vinzent Steinberg]

I tried the things Kirill - thank you! - suggested. I used

$ ./configure --extra-cflags="-fPIC" --prefix=`pwd`/tcc-root

This worked for tcc, but not for libtcc, there seems to be a bug:

$ python compilef.py
tcc: file '/usr/local/lib/tcc/libtcc1.a' not found
Running tests...
Traceback (most recent call last):
File "compilef.py", line 555, in <module>
test_clambdify()
File "compilef.py", line 410, in test_clambdify
cf1 = clambdify((x, y), f1)
File "compilef.py", line 260, in clambdify
return _compile(code, len(args))
File "compilef.py", line 228, in _compile
__run(libtcc.tcc_relocate(tccstate)) # fails if link error
File "compilef.py", line 205, in __run
raise Exception('could not run libtcc command')
Exception: could not run libtcc command

libtcc seems not to be configured for the correct path.

Thanks :) !

I run tcc 7bebf1f59a983255e6c029995583f360f30f1a04 from here:

http://repo.or.cz/w/tinycc.git

and everything seems to be just fine:

Vinzent, could you please try latest tinycc from git?
