[cfe-dev] Static Linking and loading "libclang.so"

[David Tweed]

Hi,

Note that there may be a slightly different issue: to my understanding Android actually provides a lot of the system calls expected of a Unix-y environment, but often puts them in different libraries. (At the very least, it looks like the linker is looking directly for libdl.so.2, which may not be the version used on Android, or as mentioned the functionality LLVM wants may actually be resident in a different .so file). However, I'm not remotely expert of the intricacies of Android, so I'll leave further advice for someone who's actually built LLVM for Android :) (In the worst case that no-one has done this you may have to figure out the dependencies and change the LLVM build-files yourself.)

Cheers,
Dave

Hi Anton,

libdl is required (as others) and probably not installed in your target system. You should be able to install it via yum/apt-get etc.

Installing Clang via packages would probably bring that dependency automatically, but you compiled it from scratch on a separate machine, so dependencies won't be met automatically.

And, yes, Clang/LLVM libraries are huge, especially ones with debug symbols in it.
