One of the problems is that the library is not even at version 0.0.2, that means its going to change frequently. I was actually hoping to use it as a learning tool for building my own libraries and understanding the compiler. I actually don't want to install the library because I want to treat it as part of my overall project (this is as much about setting up good project environments as anything else). If the library provides a *-uninstalled.pc (libvfcgi-uninstalled.pc), you can pretend it's installed by setting the PKG_CONFIG_PATH (environment variable) to the directory where that file is. Than calling valac with respective --vapidir and --pkg libvfcgi should do the right thing automagically. This is special feature in pkg-config, that it looks for package-uninstalled.pc in preference to package.pc, provided for exactly this kind of situation. -- Jan 'Bulb' Hudec b...@ucw.cz ___ Vala-list mailing list Vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list
Re: [Vala] Newbie Compile Time Errors
Hi, 2010/3/11, Jeff Cave jefferey.c...@gmail.com: I've decided to start tinkering with Vala (come from MS C# background), having most of my interest in web development I've decided to start with libvfcgi. I've managed to compile libvfcgi, but can't seem to get my application (just the supplied example at this time) to link to the library (correctly at least). valac -d './bin/' -g --vapidir . --pkg glib-2.0 --pkg gio-2.0 ./libvfcgi.vapi ./ValaFCGI/fcgiserv.vala -o ValaFCGI You'll need to get C compiler flags for the library as well (the vapi isn't enough). The easiest way, if you've already installed the library, is to pass --pkg libvfcgi to valac. (you may need to add the directory where the libvfcgi.pc is installed to the PKG_CONFIG_PATH environment variable). All of these header files would be coming from the VAPI, and I don't quite get where the error is occuring: compilation of the library, the way I'm linking the library, or the compilation of fcgiserv. The problem is in the compilation of fcgiserv : if passing the vapi alone to the compiler, you'll need to pass the C compiler flags, using the -X option or by compiling to C then compiling with the C compiler. Anyway, I think it's better to install the library. HTH, Abderrahim disclaimer: I've never tried this particular library, there may be some quirks, but this is the general approach for vala. ___ Vala-list mailing list Vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list
Re: [Vala] Newbie Compile Time Errors
You will notice that these errors come from the .c file not the .vala file. When you are calling a library from a C program you must also have the .h headers installed. In practice this usually means installing a package such as libNAME-dev If you are using Ubuntu/Debian try sudo apt-get install libfcgi-dev Hope this helps, I am also a noob, but this happens to me a lot On 11 March 2010 22:11, Jeff Cave jefferey.c...@gmail.com wrote: I've decided to start tinkering with Vala (come from MS C# background), having most of my interest in web development I've decided to start with libvfcgi.
