Issue Description:

I get fatal error: 'unicode/ustring.h' file not found when compiling for Android. I have downloaded the prebuilt ICU binaries, as well as compiled them myself, and it makes no difference. As you can see from the build command below, I put all my dependencies in my home folder to make the compilation simple.

[modocache]

Sorry for the slow response!

It looks like the problem is that libicuuc.so isn't being found--specifically, it can't find the headers. Does the project exist at the path you're passing into the build script, ~/libicu-android/armeabi-v7a?

[colemancda]

Yes, I even compiled the project, and replaced the "~" with the full path "/home/coleman". I will move things to another folder and try again. Thanks for looking into this.

[modocache]

Hmm, weird. It's not as if the import was introduced recently, so I wonder why it's failing for you.

I'm currently pulling down the latest changes and attempting the build myself (CI can't come soon enough!). In the meantime, just a sanity check: you do have a file at path ~/libicu-android/armeabi-v7a/icu/source/common/unicode/ustring.h, yes? What happens if you enter the following command:

$ wc -l ~/libicu-android/armeabi-v7a/icu/source/common/unicode/ustring.h

[colemancda]

I renamed the folder and changed the build command. Still doesnt work. I am cloning and compiling again from scratch, just to be safe.

New Build command:

./utils/build-script -R --android --android-ndk /home/coleman/android-ndk-r11c --android-api-level 21 --android-icu-uc /home/coleman/libiconv-libicu-android/armeabi-v7a --android-icu-uc-include /home/coleman/libiconv-libicu-android/armeabi-v7a/icu/source/common --android-icu-i18n /home/coleman/libiconv-libicu-android/armeabi-v7a --android-icu-i18n-include /home/coleman/libiconv-libicu-android/armeabi-v7a/icu/source/i18n

Sanity check:

coleman@coleman-ubuntu:~$ wc -l ~/libiconv-libicu-android/armeabi-v7a/icu/source/common/unicode/ustring.h 1700 /home/coleman/libiconv-libicu-android/armeabi-v7a/icu/source/common/unicode/ustring.h

[modocache]

I tried pulling down the latest changes from master and running a clean build of the Android stdlib, and everything worked on my end. My current theory is that there's something wrong with your libicu build, but I haven't figured out what yet. Still investigating...

[colemancda]

Right now I am compiling with the prebuilt libICU. But I did compile it myself too and that did not work either. I am currently compiling it again and haven't run into any issues, but its a Macbook Pro 2009 so it might take a while.

[modocache]

> its a Macbook Pro 2009 so it might take a while.

Yes, I was wondering--based on the build output, it seems like you're only using 2 cores.

You're capable of building Swift normally, yes? As in, simply utils/build-script -R?

[colemancda]

Yes, no errors there. I already built it for Ubuntu 15.10 x86_64.

[modocache]

Looking at the compilation command that is failing, I can clearly see that you're passing -I/home/coleman/libicu-android/armeabi-v7a/icu/source/common and -I/home/coleman/libicu-android/armeabi-v7a/icu/source/i18n. If the unicode/ustring.h header is indeed placed there, you wouldn't be seeing the include error... puzzling.

First off, try invoking the build script again, but this time blowing away any cached CMake values you might have by using --reconfigure:

$ utils/build-script -R --android --android-ndk ~/android-ndk-r11c --android-api-level 21 --android-icu-uc ~/libicu-android/armeabi-v7a --android-icu-uc-include ~/libicu-android/armeabi-v7a/icu/source/common --android-icu-i18n ~/libicu-android/armeabi-v7a --android-icu-i18n-include ~/libicu-android/armeabi-v7a/icu/source/i18n -- --reconfigure

Make sure to change the paths to libicu in the invocation above to where they are on your machine. Double-check that they exist at the paths specified.

Second off, when posting build logs, please either upload a text file or surround the output in {code} {code} tags. That ensures JIRA formats it properly.

Third, if you encounter a build error again, even after using --reconfigure to blow away the CMake cache, try rerunning the failed compilation command. For example, from your comment above, the following command fails:

/usr/bin/clang++ -DGTEST_HAS_RTTI=0 -D_DEBUG -D_STDC_CONSTANT_MACROS -DSTDC_FORMAT_MACROS -D_STDC_LIMIT_MACROS -fno-stack-protector -fPIC -fvisibility-inlines-hidden -Wall -W -Wno-unused-parameter -Wwrite-strings -Wcast-qual -Wmissing-field-initializers -Wcovered-switch-default -Wnon-virtual-dtor -Wdelete-non-virtual-dtor -Werror=date-time -std=c+11 -fcolor-diagnostics -ffunction-sections -fdata-sections -Wdocumentation -Wimplicit-fallthrough -Wunreachable-code -Woverloaded-virtual -O3 -Istdlib/public/stubs -I/home/coleman/swift/stdlib/public/stubs -I/home/coleman/swift/include -Iinclude -I/home/coleman/build/Ninja-ReleaseAssert/llvm-linux-x86_64/include -I/home/coleman/llvm/include -I/home/coleman/build/Ninja-ReleaseAssert/llvm-linux-x86_64/tools/clang/include -I/home/coleman/llvm/tools/clang/include -I/home/coleman/cmark/src -I/home/coleman/build/Ninja-ReleaseAssert/cmark-linux-x86_64/src -I/home/coleman/libicu-android/armeabi-v7a/icu/source/common -I/home/coleman/libicu-android/armeabi-v7a/icu/source/i18n -UNDEBUG -fno-exceptions -fno-rtti -Wglobal-constructors -Wexit-time-destructors -fvisibility=hidden -target armv7-none-linux-androideabi -isysroot /home/coleman/android-ndk-r11c/platforms/android-21/arch-arm --sysroot=/home/coleman/android-ndk-r11c/platforms/android-21/arch-arm -B /home/coleman/android-ndk-r11c/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/arm-linux-androideabi/bin/ -O2 -g0 -UNDEBUG -I/home/coleman/android-ndk-r11c/sources/cxx-stl/llvm-libc/libcxx/include -I/home/coleman/android-ndk-r11c/sources/cxx-stl/llvm-libc+abi/libcxxabi/include -I/home/coleman/android-ndk-r11c/sources/android/support/include -MMD -MT stdlib/public/stubs/CMakeFiles/swiftStdlibStubs-android-armv7.dir/UnicodeNormalization.cpp.o -MF stdlib/public/stubs/CMakeFiles/swiftStdlibStubs-android-armv7.dir/UnicodeNormalization.cpp.o.d -o stdlib/public/stubs/CMakeFiles/swiftStdlibStubs-android-armv7.dir/UnicodeNormalization.cpp.o -c /home/coleman/swift/stdlib/public/stubs/UnicodeNormalization.cpp

If you encounter a build error, try copy-pasting the failed command and re-running it yourself.

[colemancda]

@modocache I created a Virtual Box instance of Ubuntu 15.10 and tried everything again, from scratch, and now I get this error.

The long version:
