<div dir="ltr">Hey guys,<div><br></div><div>I'm trying to build erlang from source (tried github and tar.gz sources from <a href="http://erlang.org">erlang.org</a>)</div><div><br></div><div>I'm running into issues when it proceeds to build the pcre side of things.</div>

<div><br></div><div>Grepping for "L_LOOP_COUNT" on the source directory yields two files that make use of it, and the build-time-generated file <span style="color:rgb(0,0,0);font-family:Consolas,'Liberation Mono',Courier,monospace;font-size:12px;line-height:16.799999237060547px;white-space:pre">erts/emulator/pcre/pcre_exec_loop_break_cases.inc .

<br>But the only use for that result is knowing that I'm not the only one seeing this and that the issue is at least 2 years old.</div><div><br></div><div>I'm not using MacOS, or kerl; I'm using Arch Linux, and building by HOWTO/INSTALL.md.</div>
<div><br></div><div>In a blind/crazy idea that it might be trying to use my system PCRE (8.34-2) instead of the one in the sources directory I tried installing some of those locally to my home directory and using LDFLAGS and CFLAGS pointing to lib/include dirs where I installed them. This had no effect. And, of course, running from a clean bash instance with no shell magic applied to the environment.</div>
<div><br></div><div>The reason I want to install from source is that I require R17 to poke around, and my distro doesn't have packages for it yet. When it failed, I tried building other Rs from source, and found I was getting the same issues.</div>
<div><br></div><div>I have the very deep feeling that I'm missing some simple thing, but can't spot it.</div><div><br></div><div>What steps would you suggest I follow? Any ideas?</div><div><br></div><div>Thanks in advance.<br clear="all">
