Hi Linux fans,

I'd like to catch a signal sent to a Linux program.

Here: http://www.freepascal.org/docs-html/rtl/oldlinux/signal.html I see: "Install signal handler (deprecated) ... This call has the same functionality as the *SigAction* call. "

So I tried to do this:
http://www.freepascal.org/docs-html/rtl/oldlinux/sigaction.html

It does not compile, as the unit oldlinux is not compiled in the "normal" Lazarus svn installation.

So I tried to add the directory of oldlinux.pp to the project options (no problem).

This now asks for adding multiple more directories with inc files (no problem either)

But finally the project gets linker errors, as "lineinfo" is not provided.

Trying to add this seemingly results in recompiling the complete rtl, which I of course don't want to do.

So: Hot to catch a signal ?

Use FpSig* in unit BaseUnix.

What does the name "old" imply to you?

Nevertheless: The functionality of SigAction is provided by FpSigAction in the unit BaseUnix. For documentation and an example look here: http://www.freepascal.org/docs-html/rtl/baseunix/fpsigaction.html

Sven

I did not want to ask before having tried on my own ;-) .

In our previous episode, Michael Schnell said:

Or any "normal" installation since it has been deprecated since 2004.

See baseunix.fpsigaction or baseunix.fpsignal.

People stubbornly trying to use it anyway is exactly the reason why it isn't compiled by default anymore. And in 2.6.2 unit libc will trigger a "deprecated" warning for exactly the same reason.

Obviously and as it should be !

It was just a documentation problem and silly me not taking "old" for "depreciated".

Thanks again,
