[ptxdist] dependency issue

[ptxdist] dependency issue

[Steve Schefter]

Hi.

I'm having an issue with ptxdist building one of the components out of order. 
Mesalib depends on host-makedepend, but it is building Mesalib first.

rules/mesalib.in starts off with:
menuconfig MESALIB
        tristate
        prompt "mesa                          "
        select HOST_MESALIB
        select LIBDRM
        select HOST_MAKEDEPEND

There's no circular dependency causing problems:  I've tried removing the one
select statement from rules/host-makedepend.in so that it has no dependencies. 
That had no effect.

ptxdist seems to be aware of Mesalib/host-makedepend dependency as
state/ptx_map_deps.sh contains the line:
PTX_MAP_DEP_MESALIB=HOST_MESALIB:LIBDRM:HOST_MAKEDEPEND:DRI2PROTO:XORG_LIB_X11:
XORG_LIB_XEXT:XORG_LIB_XXF86VM:XORG_LIB_XDAMAGE:XORG_LIB_XFIXES:XORG_PROTO_GL:
EXPAT:GCCLIBS

Any suggestions on what I might have set up incorrectly to cause ptxdist to
build out of order?  Or what, beyond the select statement, can force it to build
host-makedepend first when I run "ptxdist go"?

Thanks,
    Steve

You can try to run 'ptxdist --debug go', which prints out the make
deductions. Maybe that gives you a hint why Mesalib is built first.

Thanks Robert.

I tried that, but it just seems to confirm that it isn't considering
host-makedpend.  Details below.

First, it reports that it needs to build libdrm.  That is consistent with the 
state/ptx_map_deps.sh line I quoted earlier:
PTX_MAP_DEP_MESALIB=HOST_MESALIB:LIBDRM:HOST_MAKEDEPEND:DRI2PROTO:XORG_LIB_X11:
XORG_LIB_XEXT:XORG_LIB_XXF86VM:XORG_LIB_XDAMAGE:XORG_LIB_XFIXES:XORG_PROTO_GL:
EXPAT:GCCLIBS

But then it moves on to building Mesalib without considering host-makedepend. 
Even though there are no state/host-makedepend... files.  

All of the other state files needed by the above map_deps line are in place (eg
state/xorg-lib-x11..., state/xorg-lib-xxf86vm...) so it rightly doesn't need to
do anything with those (has already done those).  It just seems to be
host-makedepend that it isn't considering.

    Steve

Strange, I'm not seeing this here. Take a look at the generated dependencies:
$ grep host-makedepend platform-<some-platform>/state/ptx_dgen_deps.post

What does this say?

I've put the whole output below, but it looks correct to me (indicates that
mesalib depends on host-makedepend).  It indicates:
   $(STATEDIR)/mesalib.prepare: $(STATEDIR)/host-makedepend.install.post

To further debug it, I did an strace of the ptxdist run.  I can see that it
opens /usr/local/lib/ptxdist-2012.03.0/rules/host-makedepend.make.  I can also
see that it does a stat() on state/libdrm.targetinstall to verify that
dependency.  However, there is not stat() for any state/host-makedepend... file.

I'm rather stumped.

    Steve

Just to make sure:
host-makedepend is enabled in your ptxconfig, right?
Does "ptxdist install host-makedepend" do the right thing?
Where exactly does it fail when you run "ptxdist targetinstall mesalib"?

Re: [ptxdist] dependency issue

[Steve Schefter]

Thank you Michael.  Your questions lead me to see the error of my ways.

It starts with the fact that, while mesalib depends on host-makedepend, it does
the extract of mesalib before it does the install of host-makedepend.  It just
saves the further steps in building mesalib until later.

The problem is that I had it run mesalib's autogen.sh during the extract.  At
that point, makedepend doesn't exist and mesalib's configure fails.  Why did I
put it as part of extract and not prepare?  According to the notes I put in the
mesalib.make file, I was finding with it in prepare, ptxdist was attempting to
use the configure script included in the tarball (not suitable for cross
compile) before autogen.sh generated a new one.  Now moving it back to prepare I
am not finding this to be an issue, so I am not sure what else might have been
wrong at the time.

Thanks again for your help and gaining a better insight into how ptxdist decides
when to do what.

Regards,
    Steve
