</I>Hello !
Some news :
Indeed it was more difficult than I thought :
There were 21 different Makefile.in in 21 directories to modify :
I wrote a patch that replaces
-LDFLAGS = @LDFLAGS@
by
+LDFLAGS = @LDFLAGS@ -lpthread
in each of them...
Now each Makefile contains :
LDFLAGS = -Wl,--as-needed -Wl,--no-undefined -Wl,-z,relro -Wl,-O1
-Wl,--build-id -Wl,--enable-new-dtags -lpthread
And I discover that my first workaround was indeed bad :
I used
%build
%configure2_5x
%make LDFLAGS="-lpthread"
instead of
%build
%configure2_5x
%make
this allowed to package and I felt happy ;) ... but wrongly happy :(
Now that I use a correct LDFLAGS I got new errors about other undefined
references (thanks to --as-needed option)
... and I feel sad :(
There came now undefined references to 'dlopen' 'dlerror' 'dlclose'
I had to add -ldl to each Makefile.in
And now it's OK
Thanks to all of you ! I'm now less ignorant than I was ...
But packaging for Mageia will need more skill and more time than for
Mandriva ... and more patches ! (hope it's worth of it)
I will provide my spec and patch files to anyone (perhaps through
bugzilla with a package request)
Regards
Philippe
