 Posted: Thu Jan 12, 2006 3:00 am Post subject: ebuild requires remote service |
 |
|
I just spent some time updating my machine and when I went to install krecipes, it complained that I did not have a database installed:
| Code: | * krecipes needs either SQLite, MySQL or PostgreSQL to work,
* please try again with USE=sqlite,
* USE=mysql (and Qt compiled with USE=mysql) or
* USE=postgres (and Qt compiled with USE=postgres). |
That I do not have a database installed on the local machine is not a problem. I have a mysql server installed on the network so it makes no sense to install a database server on every desktop that needs to communicate to a remote server. With that kind of logic, Firefox would need Apache!
Clearly, either this ebuild is broken in nature or there is a good reason for requiring the server on the same machine. Can anyone shed some light as to why this is the case? |

The ebuild needs the MySQL libs in order to compile MySQL support into the application. Unfortunatly you can't just install the MySQL libraries into Gentoo, without installing the full MySQL server as well.
It's the same with SAMBA. If you need to mount SAMBA shares, then you need to install the full SAMBA package (client, server, etc...).
Other distros have separate packages for such stuff. But Gentoo does not have this. However... you are free to hack up a ebuild for only installing the MySQL libraries and post it to bugs.gentoo.org

Well, since you mentioned this, I decided to look through their build process. The first step I took was to read the docs provided with the source, and in the INSTALL-SOURCE file they discuss some of the ./configure options:
| Code: | Some of the more commonly used `configure' options are described here:
* To compile just the MySQL client libraries and client programs and
not the server, use the -without-server option:
shell> ./configure --without-server
If you don't have a C++ compiler, `mysql' cannot be compiled (it
is the one client program that requires C++). In this case, you
can remove the code in `configure' that tests for the C++ compiler
and then run `./configure' with the -without-server option. The
compile step should still try to build `mysql', but you can ignore
any warnings about `mysql.cc'. (If `make' stops, try `make -k' to
tell it to continue with the rest of the build even if errors
occur.)
* If you want to build the embedded MySQL library (`libmysqld.a')
you should use the -with-embedded-server option. |
I'm not exactly knowledgable in writing ebuilds (they look like perl scripts with some default callbacks and globals), but this looks like it should not be too great of a task since there is already a 'configure' option to build not only without the server, but just the libs. I don't have the time to hack up on the ebuild, test it, then submit it (right now anyways). Of course, if no one else steps up to the plate then I will be forced to because this is unacceptable. |

Think of it like with X applications - you need the X libs to build client applications even if they're running on a headless box.
Now, X is becoming modularised -- splitting the client libs from the server -- but I don't think MySQL does that yet.

Oh, I get how libraries work, it was just lost on me why I needed the server when only the libs will do. Besides, read my last post, there is support (at least according to the documentation) for a minimalist build. |

I grepped through the ebuild some more and I think this will be the solution I am looking for. It still builds the server, the tools and all of the libraries, but drops basically everything except for the libraries. I'll give this a try later today and report on the status of this.
I knew there had to be a logical explanation. |
