Hi TJF,
I've the same problem as Niro. So I've modified the file you talked about.
I also follow the instructions on your site to rebuild `libpruio.so`:
cd pruio
vim pruio_adc.bas (edit buggy lines)
./make.sh
./build.sh
After the build command a file named `libpruio.so` appear in the current
directory.
The problem is that *I can't use that library to compile anything.* If I
try to compile some of the examples shipped with the library I got the
annoying error
sos.c:(.text+0x128): undefined reference to `pruio_new' etc
I'm doing something wrong?
Thanks,
Andrea
