[Frage] Compling for Freetz

[Qemme]

Hello Freetz Developers,

I have made a program based upon this example:

http://freetz.org/wiki/libs/ftdi
But now i have to execute :

LD_LIBRARY_PATH=/mod/lib:/usr/lib/freetz
export LD_LIBRARY_PATH

every time i want to use it.
How to avaoid this?
Ive managed to add the binary to the /addon directory so it is available in the freetz image,
how can I start the binary upon boot time?

Thanx in advance.
(to moderator: My german is not to good, i hope i posted this message in the right place)

Freetz should search the directory /usr/lib/freetz without any modifications necessary.

But I get a:
./blink2: can't load library 'libusb-0.1.so.4'
when i run
root@fritz:/bin# ./blink2
firmware is: 29.04.82freetz-1.2_rc2

You can also write the lines with LD_LIBRARY_PATH to the .profile (in the Web interface Freetz->.profile), then they are executed at every login.

But will i be able to run the program as a service at start-up?

 

[RalfFriedl]

Try it.
If if doesn't work, you can add a skript to set the environment variables.

We set "LD_RUN_PATH=/usr/lib/freetz" when compiling our programms. This path is hardcoded into the binary and can be shown with readelf -d prog.

Ok, thanxs.
I fixed it with a script in init.d\rc.blink2
i placed the script in : \addon\own-files-0.1\root\etc\init.d
with the line:
export LD_LIBRARY_PATH="/mod/lib:/usr/lib/freetz:${LD_LIBRARY_PATH}"

But do you know if its possible to run this script at boot time straight from the image? (whitout editing rc.custom afterwards..)

 

[RalfFriedl]

You can always use

LD_LIBRARY_PATH=/mod/lib:/usr/lib/freetz ./blink2

instead of

./blink2
