Issues building on Debian for armhf #23

MockbaTheBorg · 2020-11-05T18:35:04Z

Hi There,

I have built this one on an armhf environment, together with Lua 5.3.6.
All seems to build fine, but when I try to do:

local cffi = require("cffi")

I get an error message:

lua: error loading module 'cffi' from file '/usr/local/lib/lua/5.3/cffi.so':
        /usr/local/lib/lua/5.3/cffi.so: unexpected reloc type 0x03

The process I am following is:
. Extract lua5.3.6
. build lua with make linux && make install
. then build cffi using -Dlua_version=vendor (I have copied the relevant files to deps folder)

cffi.so builds with no error, but gives me the message above when I try to use it.

I have no idea of what can be the issue, though I have a feeling it might be something simple I am missing.
Any help would be much appreciated.

Thanks,
Marcelo.

what meson version? this would seem like it's compiling without -fPIC in CFLAGS, even though it should, always (meson should imply it for shared libs)

also, are you building git master or the last release?

MockbaTheBorg · 2020-11-05T19:44:23Z

Hi there,

Meson is 0.56.0
Python is 3.5.5
Ninja is 1.7.2
I just did a git clone this morning.
I see -fPIC inside the compile_commands.json, except for the tests/runner, but I do not think that is needed.
I was trying this example:

local cffi = require("cffi")

This is all that's inside my minimum.lua.

I do not understand meson much, but I did some research and saw -fPIC there, that was my expectation to find the issue, but now I am lost.

Thanks,
Marcelo.

(update: I build the same way under Windows WSL and works fine, so it seems to be specific to armhf environment)

q66 · 2020-11-05T19:45:48Z

compile with ninja --verbose and you should see -fPIC in the gcc calls

unfortunately we don't have 32-bit ARM CI, so testing it is a bit tricky, Travis does not support any kind of 32-bit platform and all 32-bit machines I have here are PowerPC (which works fine here) so not much I can do in terms of reproducing it easily

MockbaTheBorg · 2020-11-05T19:50:41Z

Tried it... I see -fPIC on all build lines but the one for runner.
When I try ninja test all tests fail with killed by signal 6 SIGIOT

yeah, the output looks okay

a curious thing is the shadow warnings, they're complete nonsense; what compiler/version is it?

also, i see -llua in linkage, you should not be linking against the lua library

in fact, i now potentailly see the reason; since you are linking against the lua library, and by default lua makes a static library, you're carrying static relocs into the result, and that's why it's busted

that's not the only reason you should not link against lua on unix-likes (windows is another matter), see http://lua-users.org/wiki/BuildingModules, section "Do Not Link Modules to the Lua Core Libraries"

MockbaTheBorg · 2020-11-05T20:05:26Z

I will read that.

So what should I do then? I am not sure how to solve it, sorry.
When I build Lua is deploys lualib.a to /usr/local/lib and the .h to /usr/local/include

If I specify -Dlua_version=5.3 when building cffi it still won't find it, that's why I thought building with -Dlua_version=vendor would be the solution.
I copied those files onto the deps folder and then the build goes normal.

The compiler is gcc 6.3.0.

Thanks,
Marcelo.

q66 · 2020-11-05T20:09:07Z

wait, it's adding -llua automatically? that makes no sense, the lua dependency in meson is explicitly partial, with only compiler args and includes being added and link args being explicitly skipped

by default it's not found because lua does not ship a pkg-config file like distributions do

you can ditch the deps directory and use custom instead of vendor for now, with CFLAGS=-I/usr/local/include

q66 · 2020-11-05T20:13:08Z

i just tested with vendor and it's not linking lua, are you sure you're not setting some custom LDFLAGS

Let me triple check ... because I have tried so many different things and I might have left some garbage back.
Allow me a few minutes to just clean/rebuild
And thanks a LOT for helping with this.

q66 · 2020-11-05T20:18:36Z

could theoretically be a meson regression too, i haven't tested 0.56 yet

MockbaTheBorg · 2020-11-05T20:22:52Z

You nailed it ... the -llua was garbage from previous attempts. It works now.
I still got the below:

Not sure how to fix it, but I am not too worried about the test itself. I am ok with that as long as the cffi.so works fine.

q66 · 2020-11-05T20:26:55Z

that's with vendor or with custom? with vendor it should build fine, with custom you should also pass -Dtests=false as there is no reasonable way to ensure linkage there

MockbaTheBorg · 2020-11-05T20:33:32Z

Gotcha ... that's with custom. Makes sense.
Thank you so much for the prompt response and for the assistance. Saved the day.
