ICU problem

[Nicolò Cavalleri]

Hi,

I am trying to use a library in linux that depends on the 4.5 static version of v8, but I built the 5.0 version as I saw it has all the necessary .lib/.a files are also built in this version, and it has less bugs. However I get some linking error that has to do with icui18n, that looks easy but that I cannot manage to solve.
I get a ton of errors like the following:

/usr/local/lib/v8/out/x64.release/obj.target/icui18n/third_party/icu/source/i18n/collationtailoring.o:(.data.rel.ro._ZTIN6icu_5418CollationTailoringE+0x10): undefined reference to `typeinfo for icu_54::SharedObject'

That all have to do with icui18n, and particularly with the icu_54 namespace, resulting in:

collect2: error: ld returned 1 exit status
Makefile:15: recipe for target 'lateximage' failed

This is the build command:

g++ -std=c++14 lateximage.o latex.o -o lateximage -L/usr/local/lib/v8/out/x64.release/obj.target/tools/gyp -L/usr/local/lib/v8/out/x64.release/obj.target/third_party/icu -L/usr/local/lib/wkhtmltox/lib -L/usr/local/lib/boost_1_63_0/stage/lib -lboost_system -lboost_filesystem -lwkhtmltox -lv8_base -lv8_libbase -lv8_external_snapshot -lv8_nosnapshot -lv8_libplatform -licuuc -licui18n -licudata -lrt -ldl -pthread

Any hints?

Thank you in advance

V8 is built without RTTI, and so is the bundled ICU, I assume. Does
it work when you add `-fno-exceptions -fno-rtti`?

Actually the problem was that I forgot to use circular dependencies, as it's almost the first time I am programming seriously in Linux (in Windows this is done automatically). Thank you for the support anyway!

you can tell the linker to not care about order.. but presumably it's faster if you put them in the right order to begin with.
