msi:~/video#  g++ -fPIC --shared thrtest.c -o thrtest
thrtest.c:1: syntax error before ìnt'
thrtest.c: In function ìnt main()':
thrtest.c:5: `x' undeclared (first use this function)
thrtest.c:5: (Each undeclared identifier is reported only once
thrtest.c:5: for each function it appears in.)
msi:~/video#  g++-3.4 -fPIC --shared thrtest.c -o thrtest

msi:~/video#
msi:~/video# ./thrtest
Segmentation fault

aha...

I assume on your box it will work depending with or
without LD_ASSUME_KERNEL=2.4.1?





I think it's high time for a ".configure" for vdr, ;-)
