That's because you're using a different ptxdist version. Run 'oldconfig'
und PTXCONF_HOST_AUTOTOOLS_AUTOMAKE=y should show up in the ptxconfig file.
And then the missing files should be there, because the package is actually
built.
In general you should use the PTXdist version specified in the config file
anything else may break in arbitrary ways.

Great, thanks! This fixes the m4 problem.
A few packages later, another problem popped up though. Probably not
related:
(...)
target: host-autotools-automake.install.post
sed: can't read .../toolchain/platform-../packages/host-automake-1.16.1/bin/*:

--
I worked around it by removing the custom install stage from
host-autotools-auto(make|conf).make after copying them into the
toolchain rules directory.
Something else:
According to the selected_ptxconfig, HOST_AUTOTOOLS_AUTOMAKE is not
selected. Is this host dependency pulled in automatically without a
PTXCONF_HOST_AUTOTOOLS_AUTOMAKE=y in the ptxconfig file?
Thanks,

Right, I see the problem. The toolchain overwrites PTXDIST_HOST_LDFLAGS to
_not_ add the rpath. This is correct because the toolchain avoids any extra
shared libraries. And when this was implemented, this was done to avoid
leaking any absolute paths into the toolchain binaries.
This works in most cases, because the end result is no rpath at all. And
PTXdist will skip calling chrpath.
For some reason, the m4 build system adds the '-Wl,-rpath -Wl,/lib' so
there is a rpath. PTXdist tries to change it an fails.
Try adding configure options for host-m4 that include --disable-rpath.
Does that help?
I'm currently testing a patch for ptxdist upstream that does this. It
should be in master some time this week.

I've heard of this error, but I've never seen it myself.
Can you do the following:
$ ptxdist clean host-m4
Then move / remove platform-.../logfile
$ ptxdist -v install host-m4
And then send the logfile.
The gcc wrapper should be used when host-m4 is compiled. And it should add
a longer rpath. With '-v' the wrapper will write the full commandline, so
we can see where the rpath is lost.

[ptxdist] Toolchain: host-m4 build error
Hi,
when building a toolchain based on OSELAS.Toolchain-2018.02.x, I get the
following error at the end of the host-m4 build, in the install.pack
stage:
new rpath '${ORIGIN}/../lib' too large; maximum length 4
ptxdist: error: Failed to adjust rpath for
'~/toolchain/platform-../packages/host-m4-1.4.18/bin/m4'
--
readelf tells me:
...
0x000f (RPATH) Library rpath: [/lib]
...
So there is not enough space to put in ${ORIGIN}/../lib
--
Any idea why this is only happening in the toolchain build and how to
fix it?
Host OS: ArchLinux
Host GCC: 8.3.0
PTXdist: 2019.05.0
Thanks and best regards,
Clemens
