problem with compiling for arm linux platform?

[billchen]

hi,all
i try to cross compile the vlc-1.0.0 for arm-linux , and come across with problem.

./configure --host=arm-linux CC=arm-linux-gcc --disable-hal --disable-dvd --disable-vcd --disable-dvd --disable-directfb --disable-x11 --disable-dbus --disable-skins2 --disable-qt4 --disable-libgcrypt --disable-remoteosd --disable-telx

make

You cannot build libvlc before you built libvlccore.

[kcleung]

You cannot build libvlc before you built libvlccore.

How do you arrange the order of building these libraries?

For me, I had this error (also cross-compiling, for ARM target on AMD64 host) and a quick workaround is to configure with "--disable-shared --enable-static"

[curgan]

Hi

Also you should need libiconv.

Cheers

[Rasfunk]

I have the very same problem. Is there any solution? Static linking works, but does not find the plug-ins when running on the target.

How to change vlc/vlccore build order?

Thanks a lot.

[Rasfunk]

Okay, I guess I solved this one.

The build order is not a problem. It's the library paths. Basically, configure and/or make partly ignore the paths that I provide for libraries such as libiconv. It doesn't even search it's own ./src/.libs directory. That's why it can't find the library.

The solution is to copy all relevant libraries to the "--prefix"/lib folder (including the build's own ./src/.libs dir). After that, it compiles and runs on the target.

I have stumbled upon the same issue. I believe this may be a bug in binutils. I have compiled the exact same configuration for i686 and arm, logged all of "make", and diffed them. It turns out they both do the exact same thing and run the same command (well, duh, that was expected), but the arm binutils is
2.17.50.20070611 and the i686 binutils is 2.18.0.20080103.

If I add that rpath above, it links fine.

Rasfunk, kcleung, billchen, what binutils version are you using? (self-compiled, from binary package, ...?)

[yfwong]

Try to modify bin/Makefile. It works for me.
vlc_LDADD = ../src/libvlc.la `$(VLC_CONFIG) -libs vlc` $(am__append_2)
change to
vlc_LDADD = ../src/libvlccore.la ../src/libvlc.la `$(VLC_CONFIG) -libs vlc` $(am__append_2)

[Rémi Denis-Courmont]

This bug is fixed in VLC 1.0-bugfix and 1.0.5.
