<div dir="ltr">We've been using a configure-built libedit from <a href="http://thrysoee.dk/editline/">here</a>. We essentially build that with something like "configure --prefix=/usr/local/libedit/libedit-20130712-3.1 && make && sudo make install".<div>
<br></div><div>We then run configure something like this:</div><div><br></div><div>export LIBEDIT_PATH=/usr/local/libedit/libedit-20130712-3.1</div><div>export LD_LIBRARY_PATH=<some_paths_to_gcc_4.8.2/lib64>:$LIBEDIT_PATH/lib:$LD_LIBRARY_PATH</div>
<div><br></div><div># assume ../llvm is the source tree: i.e. we're in a build directory that parallels the source tree</div><div>configure ../llvm --enable-cxx11 --with-extra-option=-I$LIBEDIT_PATH/include --with-extra-ld-options=-L$LIBEDIT_PATH/lib --prefix=<some_install_path></div>
<div><br></div><div>That's what we're doing now. We could consider breaking out the libedit parts to the 2008-libedit spec and adding configure/cmake checks for it. That might be a nice smallish project for somebody to knock out.<br>

However, I am in the process of fixing something in llvm that is broken due to unexpected interactions between libedit, libbsd and <bsd/stdlib.h> on Ubuntu (and probably other linux variants that might implement libedit in terms of libbsd).<br>
<br>
</div>The problem here is that any Ubuntu < 13.10 (which unfortunately includes 12.04 LTS we are using) use libedit<br>
2.11-20080614 while latest lldb source/Host/common/Editline.cpp relies on libedit 3.1 API (available only for 13.10).<br>
<br>
I presume that Ubuntu < 13.10 builds should use their own libedit 3.1 probably linked statically, but I have absolutely no idea how to configure that.<br>
<br>
Currently my build here fails:<br>
