#916 In configure, use PREFIX to look for LUA_INCDIR and LUA_LIBDIR even when --ostype=linux is passed
What steps will reproduce the problem?
1. Run `./configure --prefix=/usr --ostype=linux`
What is the expected output? What do you see instead?
I’d expect lua.h to be found in $PREFIX/include/lua.h, that is /usr/include/lua.h here.
Instead I get:
Checking Lua includes... lua.h not found (looked in /usr/local/include, /usr/local/include/lua/5.3, /usr/local/include/lua5.3)
What version of the product are you using? On what operating system?
Trunk 8146:5c91fb62338e, on ALARM.
Please provide any additional information below.
LuaRocks’ configure script does the right thing, see https://github.com/luarocks/luarocks/blob/master/configure#L328
The issue is in how Prosody’s tries to guess which operating system it is running on, and does that badly, see https://hg.prosody.im/trunk/file/5c91fb62338e/configure#l187
I don't believe the 'linux' ostype preset has ever worked on anything I've ever tried.
The --ostype flag should usually be put first on the command line to avoid this kind of problem. It should be considered an alias that gets expanded into some set of other flags.
Maybe you should make it error then? Or remove the --ostype altogether, since pkg-config should work fine in every case?
