Compiling Boost.Locale

Hi, great work :)
Couldn't find the locale library (no libboost_log.so in the build directory), nor could I find a list to add the this library to.

Can you please help me compile the boost locale library as well?

Hello.

I take it you mean libboost_locale.so
Presumably the build skipped it because requirements icu or iconv are not satisfied.

You could try building them with this project.
Then add the ICU_PATH or ICONV_PATH to the run ./b2 command in my build_tools/build-boost.sh to tell boost where the libs you built are:

run ./b2 -d+2 -q -j$NUM_JOBS \
          .....
         -sICONV_PATH=path_to/libiconv-libicu-android/$ARCH \
         -sICU_PATH=path_to/libiconv-libicu-android/$ARCH \
         .........
install \

Possibly also add the --with-locale flag to ./b2

and/or try enabling exactly one of ICU/ICONV for b2 via
--with-locale boost.locale.iconv=off boost.locale.icu=on or vice versa

Hi, thanks for your response!

I tried your suggestion (also --with-locale) but getting:

  • Boost.Locale needs either iconv or ICU library to be built.

You can reproduce it using my fork, checkout the icu branch:

git clone --recursive https://github.com/david-hoze/Boost-for-Android
cd Boost-for-Android
git checkout icu

I added a submodule for libiconv-libicu-android, that's why the recursive clone

On my fork you need to run doIt.sh with arguments (instead of the hardcoded BOOST_SRC_DIR and ANDROID_NDK_ROOT).
just run:

doIt.sh BOOST_SRC_DIR ANDROID_NDK_ROOT

It builds the libiconv-libicu-android automatically if it's not already built.

Will appreciate your help in the matter :)

Hi David.

Do the ICONV and ICU libraries get built properly?

Concentrate on ICU. Place this directly in a dir of formicu/$ICU_VERSION, where 'version' is the icu version you built (eg 63.1).

This dir should have structure like:

icu/63.1
            /include
                    .......
            /libs
                   /armeabi-v7a
                                  libicuio.so
                                  .....

Pass the build-boost.sh script the parameter --with-icu=<version>

Modify the path used to search for ICU in build-boost.sh. eg.

local ICU=$NDK_DIR/sources/icu/$ICU_VERSION

->

local ICU=where_you_have_icu/icu/1.63

Then try to (clean -- make sure nothing gets cached) build again.

Note: This might work without any modification of the call to ./b2

Do the paths you set via sICONV_PATH=.. and -sICU_PATH... match exactly? (print/echo in the script to make sure).
Are you sure they were built with the same ndk (version) as you are using to build boost? (The other repo mentions requiring ndk 15).

You could possibly try enabling exactly one of ICU/ICONV for b2 via
--with-locale boost.locale.iconv=off boost.locale.icu=on or vice versa

Also make sure you're doing a clean build each time you try something new (eg could be boost build system caches the icu : no

What iconv/icu related messages appear in your "build_out.txt"?

Seems many reports of difficulty getting boost build system to detect icu/iconv even if they are there. Maybe you can glean some ideas from workaround such as described here

"The compilation errors explain why passing -sICONV_PATH as a number of people tried has no effect"

or mention of an (unused) patch here
ICU not detected in boost-locale

david-hoze commented

I can't seem to find the directory structure you illustrated..
Maybe the ICU is not being built, I am indeed getting a few errors in the build process, so I submitted an issue: pelya/libiconv-libicu-android#10.

Hello David.

I have been able to build boostlocale (with ndk 19) following the procedure I outlined above.

  • Build iconv/icu using my fork of the repo above (it includes a fix from me which hasnt been yet merged into the original).
    Note: you have to add the ndk dir to $PATH since it expects ndk-build to be callable - this is how you specify an ndk version: > export PATH=$PATH:<path_to_ndkdir>. And > export SHARED_ICU=1 from caller if you want to build a shared lib - recommended. And to sepecify an abi > export ARCHS=armeabi-v7a (choose from: arm64-v8a, armeabi-v7a, x86, x86_64)

  • Copy/move the libs/includes to a dir structure like the following:

icu/62.1
            /include
                    .......
            /libs
                   /armeabi-v7a
                                  libicuio.so
                                  .....

(This could be automated by a script .. feel free to add one :-)

  • Pass the build-boost.sh script the parameter --with-icu=<version> and export the variable ICU_DIR from doIt.sh (Youll need the latest version of Boost-for-Android for this)

Your doIt.sh should now look something like this:


ICU_VERSION=62.1   
export ICU_DIR=/home/declan/Documents/zone/low/icu

./build_tools/build-boost.sh --version=$BOOST_VERSION --stdlibs=$STD_LIBS --abis=$ABIS  --ndk-dir=$ANDROID_NDK_ROOT --linkage=$LINKAGE --verbose $BOOST_SRC_DIR --with-icu=$ICU_VERSION 2>&1 | tee -a $logFile

I get boostlocale and see that its dependent on libicudata.so, libicui18n.so, libicuuc.so, libiconv.so

Thanks a lot, it compiles!!
My fork automates all that you suggested in the doIt.sh script BTW, including a submodule for libiconv-libicu-android.

david-hoze commented

If you would like I'll be glad to submit a pull request, and add a --with-icu flag in the doIt.sh script.
let me know if you want me to.

Hi, it does indeed compile, however.. When I run it I'm getting this exception:

Please add a pull request into the "boost_locale" branch.

Would need to see your code.

Maybe you can create a repo with the app your trying to run
