Hello,
I am a complete newbie to dovecot, but do have reasonable experience in
compiling Unix/Linux software.
I am currently trying to do a cross-compile of dovecot-2.29.1 to be used
on my home office Thecus NAS (host: Thecus kernel 2.6.33 on 32-bit Intel
Atom: "i686-nptl-linux-gnu"; my build machine has Ubuntu 16.04.2 LTS)
"from ground up", i.e. I need to build and provide all dovecot
dependencies from within my module.
My compiler toolchain (using gcc-5.2.0) has been set up properly using
ct-ng and works completely fine.
I also have already successfully cross-compiled/built almost all dovecot
dependencies (zlib, bzip2, xz, lz4, openssl-1.0.2, clucene-git,
snowball-git, libexttextcat, icu) - i.e. including icu - and installed
them properly into my cross-compile build root
(/raid/data/module/Dovecot/sys as defined by Thecus module spec).
My dovecot configure/make command is as follows:
===
export PKG_CONFIG=/usr/bin/pkg-config
export PKG_CONFIG_PATH=/raid/data/module/Dovecot/sys/lib/pkgconfig
export
CC=$HOME/Thecus/n4200pro-5.2.0-toolchain/i686-nptl-linux-gnu/bin/i686-nptl-linux-gnu-gcc

make

and completes configuration just fine, but the make step runs into the
following issue which I am unable to resolve even after several hours of
investigation, so I am completely stuck at this point... :-(

As far as I can tell, my pkgconfig file
(/raid/data/module/Dovecot/sys/lib/pkgconfig/icu-i18n.pc) also seems to
be fine:

Note that even adding a line stating
LIBICU_CFLAGS=-I/raid/data/module/Dovecot/sys/include
(just in order to set it to any non-null value) to the icu-i18n.pc file
and/or setting an environment variable
export LIBICU_CFLAGS=-I/raid/data/module/Dovecot/sys/include
before running configure does NOT help to get rid of the above error...
So do you have any idea why variable substitution for LIBICU_CFLAGS does
not work, and what could be done to work around this?
Many thanks in advance for your kind help with this!
Best regards,
