>><i> Hello !
</I>>><i> Some news :
</I>>><i> Indeed it was more difficult than I thought :
</I>>><i> There were 21 different Makefile.in in 21 directories to modify :
</I>>><i> I wrote a patch that replaces
</I>>><i> -LDFLAGS = @LDFLAGS@
</I>>><i> by
</I>>><i> +LDFLAGS = @LDFLAGS@ -lpthread
</I>>><i> in each of them...
</I>>><i>
</I>><i>
</I>><i> And now you are overlinking :)
</I>><i>
</I>><i> You only need to patch the Makefile(s) that is responsible for
</I>><i> building the code that relies on pthread
</I>><i>
</I>
Hey ! You ! you are a happiness breaker :-(
><i>
</I>>><i> Now each Makefile contains :
</I>>><i> LDFLAGS = -Wl,--as-needed -Wl,--no-undefined -Wl,-z,relro -Wl,-O1
</I>>><i> -Wl,--build-id -Wl,--enable-new-dtags -lpthread
</I>>><i>
</I>>><i>
</I>>><i> And I discover that my first workaround was indeed bad :
</I>>><i> I used
</I>>><i> %build
</I>>><i> %configure2_5x
</I>>><i> %make LDFLAGS="-lpthread"
</I>>><i>
</I>>><i> instead of
</I>>><i> %build
</I>>><i> %configure2_5x
</I>>><i> %make
</I>>><i>
</I>>><i> this allowed to package and I felt happy ;) ... but wrongly happy :(
</I>>><i>
</I>>><i>
</I>>><i> Now that I use a correct LDFLAGS I got new errors about other undefined
</I>>><i> references (thanks to --as-needed option)
</I>>><i> ... and I feel sad :(
</I>>><i>
</I>>><i> There came now undefined references to 'dlopen' 'dlerror' 'dlclose'
</I>>><i>
</I>>><i> I had to add -ldl to each Makefile.in
</I>>><i>
</I>><i>
</I>><i> And overlinking again :)
</I>><i>
</I>
Argh !
You killed me ;-(
>><i> And now it's OK
</I>>><i>
</I>>><i> Thanks to all of you ! I'm now less ignorant than I was ...
</I>>><i>
</I>>><i> But packaging for Mageia will need more skill and more time than for
</I>>><i> Mandriva ... and more patches ! (hope it's worth of it)
</I>>><i>
</I>><i>
</I>><i> Of course it is worth it...
</I>><i> By finding and fixing issues like this (and also send the fix upstream)
</I>><i> the quality of the code is improving...
</I>><i>
</I>><i> --
</I>><i>
</I>><i> Thomas
</I>><i>
</I>You gave me some more work indeed :
>><i> I will provide my spec and patch files to anyone (perhaps through
</I>>><i> bugzilla with a package request)
</I>><i>
</I>Mageia will have to wait for sometime :...
There are 21 makefiles
There are 0 or 1 or 2 links to add to them (but which of them really
need the added links ?)
Than means some combinations to try :
2 square to the power of 21 = 2097152 if I blindly test all of them !
If I win early I will try the casino
;-)
I will try a rational approach to decrease the number of tests to do...
Anyway... Did you think that inactivating the --as needed option will
imply so much time to build only one package ?
I really am afraid with this !
