Full Autotools build

[sunpho84]

• GPU and SPI not yet enabled
• A single long Makefile.am: this might be broken in many files if you prefer, though I can't see a practical reason for doing that

[kostrzewa]

Thanks, I'll take a look at this next week. I'm not sure I like the single list of all source files too much, but if that's the only way to achieve the desired goal, so be it.

[sunpho84]

No no one can certainly split the Makefile.am across multiple files and use include directive to collect them in the main Makefile.am, if you prefer. I can do that quickly.
What I find cumbersome, is to split the build into (in)convenient sublibraries. Given that you always link all of them, there is little reason to have a libsolver, a libhmc, etc etc, I would keep just libtmlQCD as a single target. That's also beneficial to parallel compilation.
In any case, I can arrange for split sublibs if you wish.

[sunpho84]

Ok now the Makefile.am is split across different files, included in subdirs, there is still a bit of a mess in the master Makefile.am and one would probably split the main folder sourcefiles list into a dedicated file (or put the files in an appropriate directory?)

[urbach]

did I tell already how much I love automake!? ;)

anyhow, I guess I have to type automake in the main directory, correct?

Here
automake-warnings.txt the list of warnings and errors... anyone?

[urbach]

btw: I have automake (GNU automake) 1.15

[urbach]

even if I invoke automake --add-missing I do not get a configure script that would be working

[kostrzewa]

Works for me.

$ automake --add-missing
$ autoreconf

[kostrzewa]

include files are not installed by make install, the rest seems to work as expected

[kostrzewa]

of course, the external libraries should be taken care of

[urbach]

well, this is what I get after an `autoreconf`: ``` $> autoreconf configure.ac:15: error: required file './compile' not found configure.ac:15: 'automake --add-missing' can install 'compile' configure.ac:13: error: required file './missing' not found configure.ac:13: 'automake --add-missing' can install 'missing' autoreconf: automake failed with exit status: 1 ``` another round of `automake --add-missing` solves it then. Is this ment seriously?

Works for me. ``` $ automake --add-missing $ autoreconf ``` -- You are receiving this because you commented. Reply to this email directly or view it on GitHub: #415 (comment)

That's why one usually has an autogen.sh script.

It worked with a single invocation of automake --add-missing for me though (in a fresh source directory). Should be tested on Marconi and Jureca, just in case problems arise there.

[urbach]

has this been tried with `--enable-sse2`?

[kostrzewa]

I think the full set of configure options needs to be mapped out. Ideally one would do this via travis...

[kostrzewa]

SSE2 / SSE3 seem to work, but produce the kinds of errors upon compilation that we got a while ago from the single precision stuff

[urbach]

for me it does not compile with SSE2

[urbach]

but this might not be due to automake

[kostrzewa]

for me it does not compile with SSE2

no, it doesn't compile, but the flags seem to be defined correctly

the errors come from the single precision hopping matrix...

[kostrzewa]

and D_psi, respectively

[sunpho84]

My autgen.sh -like script (for nissa) goes like this

#!/bin/sh

rm -fr \
    aclocal.m4 \
    autom4te.cache \
    $(find . -name "Makefile.in") \
    config/{compile,config.guess,config.sub,depcomp,install-sh,missing,ylwrap} \
    configure

aclocal
autoreconf --verbose --install --force

[urbach]

and D_psi, respectively

same for me...

[sunpho84]

For what concern flags, I've modified the ALIGN stuff, adding or removing the description (if I believe correctly), but it would be better if you could check it...

[kostrzewa]

The README should probably be adjusted to contain

aclocal
autoreconf --verbose --install --force

as an instruction for generating configure.

[sunpho84]

Yes, but the autogen.sh or boostrap.shwould be advisable

[kostrzewa]

Agreed.

[urbach]

Yes, but the `autogen.sh` or `boostrap.sh`would be advisable

yes, add it please. I have no experience with automake whatsoever...

The wikipedia article about GNU Autotools has a nice flowchart, this really helped me when I tried to compile the USQCD code.

I have found that aclocal && autoreconf -fiv is indeed sufficient. Just calling autoconf (even with flags like --install or --add-missing) does not do everything that is needed. In principle one does not need to call autoconf manually. automake should not be called manually, the configure script will do that.

For USQCD projects the following commands do all I need:

aclocal
autoreconf -fiv
./configure
make
make install

If this is nice, I don't want to hear what's the feeling of setting up a project with cmake

autoreconf -fiv

same same

So what about the gpu side?

[urbach]

there are very good reasons that I never used cmake or automake for tmLQCD... ;)
