Bugzilla Bug 16678

after upgrading slang to 1.4.8, emerge wanted to upgred jed to 0.99.16-r1, but 
jed compilation failed with:

if /var/tmp/portage/jed-0.99.16-r1/work/jed-0.99-16/src/x86objs/chkslang jed 
10311 ;\
then exit 0; else rm -f /var/tmp/portage/jed-0.99.16-r1/work/jed-0.99-
16/src/x86objs/chkslang; exit 1; fi


******
slang.h does not match slang library version.  Did you install slang as
as a shared library?  Did you run ldconfig?  You have an installation problem
and you will need to check the SLANG variables in the Makefile and properly
set them.  Also try: make clean; make

I really don't think I have other version of slang installed...

please post `emerge info`, `qpkg -I -v slang`, and the config.log file from the
build directory

Created an attachment (id=8879) [edit]
jed's config.log

i get this problem as well. seems to be something related to the recent
slang-1.4.8 upgrade.

i modified the chkslang script in JED to give me more information, and
curiously, it says:

"slang.h (10405) does not match slang library version (10408)."

but in /usr/include/slang.h, it says 10408. very weird indeed. looking into
this further.

ok, for some reason, gcc copies random header files into 

/usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.2/include

try removing /usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.2/include/slang.h and then
try again. meanwhile i'll try and find out why the hell gcc is doing this?

let us know if that works after you remove the cached old version of slang.h

Yes... it works now :)

Thanks

ok, closing this bug now.

i committed a fix into slang to make sure it removes any older cached header files created by gcc. apparently, the reason is that slang.h is non-ANSI compliant, so gcc > 3 tries to correct this and overrides any slang.h in /usr/include with its own version.

the jed making problems shouldn't reoccur any more.
