[gentoo-dev] ebuild question

[pepone pepone]

Hello I ´m trying to create a new ebuild for Ice (Internet Comunication Engine)
       http://www.zeroc.com

       this is my first ebuild and i want know how in my ebuild can
detect the version of a  program that is installed in the system

the problem is that in order to suscefuly compile my package i need to
export DB_FLAGS  and DB_IFLAGS acording to the db version that is instaled
in the system

thanks in adavantage

you should be able to use the has_version function.  More details at

has_version only returns 0 or 1 depending whether the package is installed or
not, so it's useless in this case.  best_version would be a better alternative,
however that alone won't solve the problem.

Read about best_version in the ebuild(5) manual page.  After you're done with
that, read about the versionator eclass in the versionator.eclass(5) manual
page (may have to emerge portage-manpages).  You'll probably have to use a
combination of both to do what you're trying to achieve.

That's all that's really needed since all you'd care about in this 
instance is the existance of one of 2 or 3 major versions.  Just look 
for >=sys-libs-4.0 then 3.0 and so-on, compiling for the first one you 
find.

That would be the incorrect way of going about it.  As I said in my previous
post, use versionator.eclass.  One call to best_version and one call to
get_major_version is all that's needed.

O.o!

Great, I have in my overlay an ebuild which I made and I'm testing it right
now..

hdf5_hl-1.6.2.1.ebuild - hdf5_hl-5162p1.tar.gz

---
PKG_VER="${PV:0:5}"
PKG_REV="${PV:6}"
MY_PKG="${PN}-5${PKG_VER//./}${PKG_REV:+p${PKG_REV}}"

SRC_URI="ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/hdf5_hl/src/${MY_PKG}.tar.gz"

Use of versionator.eclass seems to be the elegant solution, just I need to
read de eclass...

Cool stuff Ciaran, ;-)
