RE: [Ltib] Building xorg-server; missing dependencies?

[Alexandre Paradis]

Do we need to adjust some paths?  I can't reproduce the failure inside
the ltib shell with the gcc command below:

LTIB> gcc -shared  .libs/evas_engine.o .libs/evas_outbuf.o

Hi Alex,

This really has me scratching my head now.  I just checked and I'm
building the same platform, and my toolchain is the same one.

Aside from you being on Gentoo (and I don't see how that is a factor), I
don't really see why we are getting different build results?

In your build, the telling thing to me, which must first be eliminated
is the presence of the absolute link references to: /usr/lib/libX11.so
etc.  If you can go back to a failure situation again and then do:

$ ./ltib -m shell
$ export FS_DEBUG=1
> cd rpm/BUILD/evas*
> gcc
-shared  .libs/evas_engine.o .libs/evas_outbuf.o .libs/evas_x_buffer.o
.libs/evas_x_color.o .libs/evas_x_main.o  -Wl,--rpath
-Wl,/home/alex/savannah/ltib/rpm/BUILD/evas-0.9.9.050/src/lib/.libs
-L/usr/X11R6/lib /usr/lib/libX11.so /usr/lib/libXext.so
../../../../src/lib/.libs/libevas.so  -Wl,-soname -Wl,module.so -o
.libs/module.so

this should fail as before, then try as (no abs link refs):
> gcc
-shared  .libs/evas_engine.o .libs/evas_outbuf.o .libs/evas_x_buffer.o
.libs/evas_x_color.o .libs/evas_x_main.o  -Wl,--rpath
-Wl,/home/alex/savannah/ltib/rpm/BUILD/evas-0.9.9.050/src/lib/.libs 
-L/usr/X11R6/lib -lX11 -lXext ../../../../src/lib/.libs/libevas.so
-Wl,-soname -Wl,module.so -o .libs/module.so

Maybe this will work??? anyhow both those gcc commands are all on one
line (the emailer will wrap).

Regards, Stuart

not for powerpc, as opposed to mine which still tries to use them. Would
this mean that it is first searching the libs on the host, then on your
host you also have the path roots/usr/X11R6/lib/ which "ld" would look
into and find the correct libs?
