I'm extending the capabilities of flx_pkgconfig, so it can query pkgconfig
(*.pc)
databases.
pkgconfig is a seriously bad program. It is very badly written,
it is full of bugs, and it has limited capabilities (which is why
flx_pkgconfig was written). Indeed, it has a very specialised application
and it can't even handle that properly.
I have extended flx_pkgconfig (next commit) to add;
--help
well it should always have had that ..
--extension=fpc
to set the extension to look for, if you set pc it will find pkgconfig files
instead of flx_pkgconfig files (will play with this to see if both can
be queried at once later).
I have added variables as used by pkgconfig:
prefix = /usr/local
lib = ${prefix}/lib
Libs: -L${lib} -lmylib
Also blank lines are tolerated, and lines starting with # are skipped.
pkgconfig allows trailing # comments which are not handled yet.
Pkgconfig also doesn't allow comma separators: some options go
like this:
-W1,linkeropt,-W1
and have embedded commas, so I'll have to remove that feature.
Some convenience flags such as --cflags can be added later.
A couple of stupid features not supported yet: splitting linker switches
into -L and -l. Probably support that by filtering values based on
a regexp (although at this point, flx_pkgconfig is very carefully built
to avoid using any regexps).
One of the biggest problems is version control. In pkgconfig, a Version
field provides the version, and you can write:
Requires: fred < 1.2.11
Requires: joe = 2.3.4
This makes the "Requires" field special (since the version requirement isn't in
the
correct form of a general field). Also breaks the dumb parsing I'm using for
variables
(which would think the last line is an assignment of 2.3.4 to variable
"Requires: joe" :)
However with enough hacks and tweaking, flx_pkgconfig can probably be made
a "drop in" replacement for pkgconfig.
