Does FPC support the graph unit on OSX?

No, not yet. A graph unit for Mac OS X will probably be built on top of SDL.

Hello!

The following happened while compiling the maze example application. Do I need to compile this from a graphical terminal? I was using SSH.

This is no you must run it on a local machine in a terminal (not from X)

Or am I missing something?

Yes, you need libsvga (package name maybe svgalib) installed.

/usr/bin/ld: cannot find -lvga maze.pp(508) Error: Error while linking

Ciao,

No. source rpm usually have srpm as extension.

It didn't give any errors but didn't fix my compile problem, either.

Then it only installed the lib, but didn't do some postconfiguration step.

Try finding the lib(s)vga.so.x.y library, and create a symlink to it called libvga.so

Sorry for asking a Linux question.... but is there a right way to get the graphics library installed?

It is very distribution (and package) dependant.

However, the bottom line is

1) that if FPC says: "can't find -lxxx" then you are missing a libxxx.so file. Usually that means you have to install the corresponding package
2) A corresponding package sometimes doesn't install libxxx.so, for various reasons (see below), you can correct this by creating a symlink with ln -s libthenamethatwasinthepackage.so.123.5235 libnameitshouldbe.so

The reason for (2) is because

- you might want to install multiple versions of this package, and if all would call the main lib "libxxx.so" this would cause conflicts. This is solved by appending the .x.y.z versioning to the libxxx.so file
- Some libraries have multiple names. e.g. a lot distributions/OSes call "libsvga" libvga, and some call "ncurses" curses, all for historical reasons.

This is already 1 step. The second step is installing the svgalib-devel package. Alternatively, install a symbolic link to it:

cd /usr/lib
ln -s libvga.so.x.y.z libvga.so

replace x.y.z with the actual version number.

Thanks!

The other platform I can use is Red Hat Linux 7.1

Thank you guys! You're very helpful!

I downloaded the rpm and typed:

#rpm -i svgalib-1.4.1-2.src.rpm

I don't think this is how this type of RPM gets installed.... it's a "source" RPM I take it?

It didn't give any errors but didn't fix my compile problem, either.

Thanks, again.

ps. BTW, we're eventually converting a DOS-based Turbo Pascal program. This program is used by scientists all over the world. They will LOVE to upgrade to Linux!

Thanks, everyone. I had to download the source... couldn't get the RPMs to work. But after compiling I followed your link instructions and voila...

Thanks, again. Success feels good. 8^)
