    Hi all
8/15 18:18:14 Sante
    i am working in a fakeroot environment trying to compile something
    video related (NMM)
8/15 18:18:20 Sante
    it says im missing a library called ltdl
8/15 18:18:25 Sante
     so i installed libtool-1.5.22
8/15 18:18:32 Sante
    i am using a powerpc architecture so when i run ./configure i use
    CC=ppc-gcc CXX=ppc-g++ --arch=ppc
8/15 18:18:38 Sante
    then run make and make install
8/15 18:18:42 Sante
    and it appears fine
8/15 18:18:48 Sante
    but when i run file library it says Intel 80386
8/15 18:18:48 Sante
    Sante anyone could help me as to what I am doing wrong ?
8/15 18:18:48 Sante
    Sante .............. anyone awake ?
8/15 18:18:55 Sante
    sorry wrong paste
8/15 18:19:16 Sante
    so any1 kno anything to help me out ??
8/15 18:22:36 mmp
    Sante: when the compilation starts, you see that make calls 'ppc-gcc',
    or just 'gcc?
8/15 18:23:00 Sante
    ppc-gcc
8/15 18:25:15 mmp
    hmm, and if you do file *.o in the build directory, the files are
    ppc or 386 ones?
8/15 18:25:34 *
    mmp wonders how could be ppc files linked into 386 executable
8/15 18:26:12 Sante
    hang on
8/15 18:28:01 Sante
    the build directory, u mean the directory in which the files are
    installed?
8/15 18:28:16 Sante
    ie usr/local/lib?

    Hi, yesterday I had a problem and until today I didn't solve
    it. When trying to bootstrap stage1 uclibc I get the error right
    at the strat of the process: * Executing: emerge --oneshot -p -v
    virtual/os-headers sys-apps/texinfo sys-devel/binutils sys-devel/gcc
    virtual/libc virtual/baselayout sys-libs/zlib ------ These are the
    packages that I would merge, in order: ----- Calculating dependencies
    |!!! Cannot resolve a virtual p
8/15 18:32:16 mmp
    Sante: where you build the sources, where are the object files
8/15 18:32:36 mmp
    Sorry that I did not write it more clear...
8/15 18:35:32 Sante
    the object file is POWERPC
8/15 18:37:48 jooopy
    is the http://www.bulah.com/embedded-guide.html should work? Are
    ppl here have experience with it?
8/15 18:37:54 hiyuh
    Sante: to use more sane CHOST/CTARGET/CBUILD is worth to consider,
    though.
8/15 18:38:06 hiyuh
    Sante: and then,  -I$target_incdir -L$taregt_libdir could help. but
    some apps'/libs' configure script sucks x-compile.
8/15 18:38:24 jooopy
    I also have something I don't understand
8/15 18:38:41 *
    theBear doesn't understand many things
8/15 18:39:12 jooopy
    If I run on the host system : ROOT="/tmp/minime" USE="make-symlinks"
    emerge uclibc busybox baselayout-lite dropbear
8/15 18:39:36 jooopy
    This should make an image, or I need more steps?
8/15 18:40:09 hiyuh
    jooopy: nope, virtual/* will be provided by installed packages,
    IIRC. don't emerge explicitly these virutal stuffs.
8/15 18:40:14 Sante
    ok
8/15 18:40:50 Sante
    what do u mean by CHOST/CTARTGET/CBUILD
8/15 18:41:22 jooopy
    hiyuh:  How do I know what are the virtual stuffs?
8/15 18:41:38 theBear
    the category is virtual/
8/15 18:41:39 jooopy
    hiyuh: I just ran ./bootstrap
8/15 18:42:34 jooopy
    hiyuh: should I block libiconv in /etc/portage/packages.mask ?
8/15 18:43:12 hiyuh
    jooopy: the sources always with you. :P
8/15 18:43:43 Sante
    hiyuh: i dont understand the CHOST stuff, and what u wrote next
8/15 18:44:44 hiyuh
    jooopy: sound like you're trying to build from stage1?
8/15 18:45:26 jooopy
    hiyuh: yep, but I don't realy have to. I just follow
    http://www.bulah.com/embeddedgentoo.html
8/15 18:45:38 jooopy
    hiyuh: Should I start from stage 3?
8/15 18:46:17 jooopy
    hiyuh: can you refer me to a good howto ?
8/15 18:47:54 hiyuh
    jooopy: first of all, see the
    topic. http://arcanux.org/guidexml/cross-development.html
8/15 18:48:30 jooopy
    ok
8/15 18:49:25 hiyuh
    Sante: you should read env-ver section in this documents.
8/15 18:49:48 Sante
    ok
8/15 18:49:55 Sante
    ehmm which documents?
8/15 18:50:00 Sante
    http://arcanux.org/guidexml/cross-development.html ?
8/15 18:50:05 hiyuh
    yep
8/15 18:50:25 Sante
    im not using gentoo btw
8/15 18:50:30 Sante
    but ill have a look
8/15 18:53:20 hiyuh
    Sante: except some commands in this document, these info are common
    knowledge of x-development, IMHO.
8/15 18:54:49 Sante
    ok
8/15 18:55:09 Sante
    i still dont really get my problem, i mean it appears to be compiling
    correctly
8/15 18:55:26 Sante
    can i show u the ./config and make dumps ? maybe u can help me out
8/15 18:57:37 hiyuh
    Sante: of cource, you can show us. but I cann't bet you expext. :P
8/15 18:58:08 hiyuh
    s/expext/expect/
8/15 18:58:12 Sante
    hehe
8/15 18:59:05 Sante
    http://pastebin.ca/132432
8/15 18:59:08 Sante
    thats configure
8/15 18:59:39 Sante
    and make
8/15 18:59:40 Sante
    http://pastebin.ca/132433
8/15 19:04:15 Sante
    any idea ?
8/15 19:08:07 hiyuh
    Sante: hmm? it looks libtool installing is ok. then, you mean you
    couldn't link target libs?
8/15 19:15:35 Sante
    i mean
8/15 19:15:49 Sante
    when i try to compile my app it says ltdl not found
8/15 19:21:46 hiyuh
    hmm? so, ltdl is "libltdl.{a,so}" as your target lib?
8/15 19:29:31 hiyuh
    Sante: FYI, this is "locate ltdl" result of my ~ppc gentoo (but
    notice, only self compilation tools was installed).
8/15 19:30:02 hiyuh
    http://rafb.net/paste/results/OmlsA693.html
8/15 19:30:25 hiyuh
    So, if your apps need to link libltdl.{so,a}, you should do like that.
8/15 19:30:38 hiyuh
    1) compile it with "-I$inc_dir", $inc_dir is where target's ltdl.h is.
8/15 19:30:41 hiyuh
    2) link it with "-L$lib_dir -lltdl", $lib_dir is where libltdl.{so,a}
    are.
8/15 19:31:24 hiyuh
    maybe, you should check step 2), IMHO.
8/15 19:48:44 Sante
    wait
8/15 19:48:56 Sante
    at what step do I link with -L$lib_dir -lltdl"
8/15 19:48:57 Sante
    ?
8/15 19:49:23 Sante
    and i dont have libltdl.so
8/15 19:49:49 Sante
    only .a
8/15 19:50:00 Sante
    when i compile with standard gcc i get the .so aswell
8/15 19:50:07 Sante
    hiyuh: is that normal ?
8/15 20:33:35 hiyuh
    Sante: *.a is an "ar archive" for static link. *.so is "shared object"
    for dynamic link... if you specfied to build only "ar archive"
    or your x-compiler can only build static ones, it is normal.
8/15 20:34:27 Sante
    ah ok
8/15 20:34:37 Sante
    then my compiler can only do static ones
8/15 20:35:05 Sante
    but why does my app complain that ltdl is not installed then ?
8/15 20:40:22 hiyuh
    Sante: nope, it may be not your apps' fault. to link is to working
    of linker as a part of toolchain...
8/15 20:40:35 Sante
    hmm ok
8/15 20:40:37 hiyuh
    in static link case, libltdl.a should be linked when it was build,
    and it's in $lib_dir was specfied -L option. and then you need
    -static as well.
8/15 20:40:50 Sante
    hang on
8/15 20:40:52 Sante
    where do i do this ?
8/15 20:42:47 hiyuh
    sane fixing is poking *.{in,am,ac} or so. otherwise, poking Makefile
    or manually link it where it failed, IMHO.
8/15 20:43:27 Mimil
    hi all
8/15 20:44:07 Sante
    ok
8/15 20:44:08 Sante
    safe
8/15 20:44:28 Sante
