Bugzilla Bug 14177

I get this when I tries to build flightgear-0.9.1 ebuild or compiles the tar
file.

...
make[2]: Entering directory
`/var/tmp/portage/flightgear-0.9.1/work/FlightGear-0.9.1/src/Network'
make[2]: *** No rule to make target `jpg-httpd.cxx', needed by `jpg-httpd.o'. 
Stop.

I tried to run ./configure --without-network with same result
I have reported it on the flightgear list. 
install ebuilds:
sys-devel/gcc-3.2.1-r6 
dev-db/metakit-2.4.7.37
media-libs/plib-1.6.0
dev-libs/simgear-0.3.1 
app-games/flightgear-0.9.1

please post `emerge info`

I thing the problem is related to simgear or plib.

Instead I install the current version from cvs (--prefix ~/Local :-).
And got the opposit problem: 
   jpeg-factory was missing in "Simgear-CVS"

Has "FlightGear/configure" a bug that detect jpeg-factory by a mistake?

Could you please try 0.9.2?

Same result:

make[2]: Entering directory `/var/tmp/portage/flightgear-0.9.2/work/FlightGear-0.9.2/src/Network'

If I install SimGear with --with-jpeg-factory it works!
That what I do with the CVS version of FlightGear, SimGear and plib
The cvs version are install in my home dir: ~/Local

I can live with this bug because I use the current cvs-version of FlightGear.

I thing the problem is related to includes files, GNU configure and maybe a bug in my installation of gentoo.

oddly enough if i install simgear + flightgear w/out using --with-jpeg-factory
in simgear 
it'll work ... 

but if i emerge simgear with --with-jpeg-factory then flightgear fails with the
same error 
you reported 

I have look at Flightgear-devel mail-list and found this one:

http://seneca.me.umn.edu/pipermail/flightgear-devel/2002-March/005444.html 
> I think what we need to do is change the test in

> jpeg factory support and a suitable libjpeg is available

and from my /usr/lib/libsgscreen.a: 
> nm /usr/lib/libsgscreen.a |grep Factory
was empty!

but my local CVS build with --with-jpeg-factory
> nm /home/lasj/Local/lib/libsgscreen.a |grep Factory

So the problem is in FlightGear and it is a autoconf problem :-).

I with try to make a workaround/fix for the FlightGear ebuild.

From the standart ebuild/emerge:
checking for simgear 0.3.3 or newer... 0.3.3 or greater... yes
checking simgear/screen/jpgfactory.hxx usability... yes
checking simgear/screen/jpgfactory.hxx presence... yes
checking for simgear/screen/jpgfactory.hxx... yes
checking for jpeg_start_compress in -ljpeg... yes
checking zlib.h usability... yes

Workaround/fix to src_compile() is:
src_compile() {
	# Bug fix for bug 14177: flightgear failed -- missing jpg-httpd.cxx
	# Wrong detection of jpgfactory in SimGear 
	i=configure
	mv $i $i.orig;
        cat $i.orig | \
	sed 's|#include <simgear/screen/jpgfactory.hxx>|#include <simgear/screen/jpgfactory.hxx-faile-include>|g' > $i
	chmod +x $i

	egamesconf 
	emake || make || die
}
It let the detection of simgear/screen/jpgfactory.hxx fail:
checking for simgear 0.3.3 or newer... 0.3.3 or greater... yes
checking simgear/screen/jpgfactory.hxx usability... no
checking simgear/screen/jpgfactory.hxx presence... no
checking for simgear/screen/jpgfactory.hxx... no
checking zlib.h usability... yes

I attach the new ebuild. 

Created an attachment (id=13660) [details]
flightgear-0.9.2-r1.ebuild

yeah that script fixed the prob alright :) 
 
excellent job on tracking this thing down ... i'm not nearly involved in the projects as you 
are ;)
