[ptxdist] rpath maxmimum length error

[ptxdist] rpath maxmimum length error

[Rouven Czerwinski]

Hello,

I'm currently hitting the following error while trying to build
toolchains for Arch Linux:

----------------------------
target: host-m4.install.pack
----------------------------

new rpath '${ORIGIN}/../lib' too large; maximum length 4

ptxdist: error: Failed to adjust rpath for '/home/phoenix/build/tc-build/src/OSELAS.Toolchain-2018.12.0/platform-arm-v7a-linux-gnueabihf-gcc-8.2.1-glibc-2.28-binutils-2.31.1-kernel-4.19-sanitized/packages/host-m4-1.4.18/bin/m4'

make: *** [/opt/lib/ptxdist-2018.12.0/rules/post/ptxd_make_world_install.make:60: /home/phoenix/build/tc-build/src/OSELAS.Toolchain-2018.12.0/platform-arm-v7a-linux-gnueabihf-gcc-8.2.1-glibc-2.28-binutils-2.31.1-kernel-4.19-sanitized/state/host-m4.install.pack] Error 1

Because chrpath can not dynamically allocate more space for the new
rpath. I found a bug report for oe-core which ran into the same issue
under [1].
Their suggested solution is to switch to patchelf [2]. Is there an interest
for this switch in ptxdist as well? If so I'll gladly send-patches.

Regards,
Rouven

PTXdist should specify a long enough rpath at build-time. Please do a clean
build with '-v' and send the host-m4.compile section from the logfile.
