Re: [fpc-pascal] Where does Write(Ln) actually write to?

As suggested yesterday, you need to implement some of the other Do_* functions, at least Do_Open, otherwise some of the fields in the TextRec/FileRec are not initialized properly (e.g. the input/output mode). Just have a look at one of the existing implementations. Tomas ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Re: [fpc-pascal] How to use OpenGL 2.0 features
OpenGL 3.x also deprecates many OpenGL 1.1 functions (for example immediate
mode). OpenGL 1.1 is not loaded (as there is no need even on windows) so how
does the 'flexibility' help us there?
Binding flexibility is required, if application is to be distributed.
There's no way to say, what kind of OpenGL drivers is installed on the
next machine.
for example, an application uses some 2.0 features (that're available
in earlier gl versions as some extensions)
The application will run fine with OpenGL 2.0 drives installed, but if
there's older drivers it will probably fail.
The most robust code is the following:
if not Load_SomeFunc_asCore and
not Load_SomeFunc_asExtension then begin
writeln('Please, update OpenGL drivers');
Halt;
end;
I know, it's easy, to say: My application requirement is GL 2.0 or
higher, but, personally, i prefer to care about the user, rather
making him/her to install latests drivers.
thanks,
dmitry

[fpc-pascal] Daemon question
Hi, I wrote a daemon monitoring my solar powerstation. It works fine but I want to extend it. At the moment I log everything to file, and I put some data into rrdtool. I would like to be able to ask the daemon some information, but I don't know how to do this. I made some signals : sigterm to terminate gracefully, sighup to restart, sigusr0 to get the uptime and sigusr1 to get some device-info. Except, sigusr0 and sigusr1 use writeln's to output the data which I never see when I ask for them (kill -10 processid). Where do these writeln's write to ? Sigterm and sighup do work fine, so I think my handler is OK. How can I get that info ? It should be software-independent, because I would like to use php to get that information. I thought of writing the info to a file, but that info is updated every 15 seconds. I think it's not good to write a new file every time. Now I'm writing this, I could write to a file after receiving a signal, and then reading this with php. Thinking about it, does php support sending signals ? Back to the books. Before you ask, I'm running Linux. Thanks for any pointers, Koenraad Lelong. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] Link libglx library.
Hello. I'm working on a project that needs the GLX library. It compiles but when running it returns that error: ./exbasic: symbol lookup error: /usr/local/lib/libagl.so: undefined symbol: glXQueryExtension In other forum a colleague suggest that it doesn't links with the libglx.so . I'm trying to force it using the command line but it returns that error on compiling time: fpc -02 -Sh -kglx examples/agl/exbasic.pp -oexamples/agl/exbasic ...

[fpc-pascal] Sourceforge Lazarus DEB Fails on Ubuntu Hardy Heron
The current .DEB lazarus-ide_0.9.26.2-0_i386.deb available from the Sourceforge repository reports a dependency error when I attempt to run it on Ubuntu 8.04. The error reads, Error: Dependency is not satisfiable: libxi6 What makes this vexing is the installer reports a dependency error when in fact I checked the Ubuntu install with Synaptic and it reports that libxi6 is present and up to date. Can anyone explain why the .DEB package is reporting a missing library when that library is present on the Ubuntu system? Is this a version issue? Can I just force the files onto the system and ignore this error. It appears to be a problem with the deb package and not the file it says is missing. --- ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
