liblttng problem with build for android

[meold]

Hello!
After i run cross/build-android-rootfs.sh I have this output. Can you help me please??

`CMake Error at src/pal/src/configure.cmake:1347 (message):

Try to build with cmakeargs -DFEATURE_EVENT_TRACE=0. It should disable to the tracing subsystem that pulls in lttng.

[meold]

@jkotas Ok, thanks
I run this: CONFIG_DIR=realpath cross/android/arm64 ROOTFS_DIR=realpath git/coreclr/cross/android-rootfs/toolchain/arm64/sysroot ./build.sh cross arm64 skipgenerateversion skipnuget cmakeargs -DFEATURE_EVENT_TRACE=0

And get this another errors:

[jkotas]

This was discussed in https://github.com/dotnet/coreclr/issues/5160. There is something wrong with detecting ucol_setMaxVariable.

@jkotas ok, thanks
But now i get another error and I can't find smth information about it.

[jkotas]

No idea about this one.

@meold this means that the ICU library headers are not present. Are you sure the rootfs was built without any errors? I remember that there was a problem that a version of the library packages needs to be manually updated from time to time when they get bumped in the repository. See the last change that did that here:
dotnet/coreclr@b3e859c#diff-64e4222a4045c49394b856c6644cefef

My guess is that some of the wget commands have silently failed and you haven't noticed (we should add bash option to the script to make sure that a failed command fails the whole script, which seems to not be there).

[meold]

@janvorli @jkotas, I updated my build-android-rootfs.sh like this(last versions from termux.net):

But none of these packages contain libintl.h, so I have the next error:
/git/coreclr/src/pal/src/locale/unicode.cpp:41:10: fatal error: 'libintl.h' file not found #include <libintl.h> ^ 1 error generated. src/pal/src/CMakeFiles/coreclrpal.dir/build.make:854: recipe for target 'src/pal/src/CMakeFiles/coreclrpal.dir/locale/unicode.cpp.o' failed make[2]: *** [src/pal/src/CMakeFiles/coreclrpal.dir/locale/unicode.cpp.o] Error 1 CMakeFiles/Makefile2:240: recipe for target 'src/pal/src/CMakeFiles/coreclrpal.dir/all' failed make[1]: *** [src/pal/src/CMakeFiles/coreclrpal.dir/all] Error 2

Any suggestions would very helpful.
Thanks.

[meold]

@janvorli, @jkotas any ideas about this problem?

[janvorli]

@meold this header should be part of gettext-dev package. So it looks like the build-android-rootfs.sh should include getting this package.

[janvorli]

The URL for ARM64 seems to be http://termux.net/dists/stable/main/binary-aarch64/gettext-dev_0.19.8-2_aarch64.deb

[meold]

@janvorli , I added this package, but this package does not contain this header file libintl.h. So I still get the same error(

[janvorli]

@meold hmm, I've checked the location of the header and it is actually part of libc on Linuxes. On Android, it is not present. It is strange though that we were able to build the stuff for android in the past just fine.
@qmfrederik, do you happen to remember if we needed to do anything special w.r.t. the libintl.h?

[qmfrederik]

@meold @janvorli Well, it's been a while since I looked at .NET Core on Android ;-).

It looks like libintl.h was previously part of libandroid-support but it has been removed in termux/libandroid-support@08ad732.

@meold Can you try downloading libintl..h and save it to a location where the compiler can find it?

From dotnet/coreclr#15751 it seems you managed to build CoreCLR for Android, how did you handle the libintl.h dependency there?

[meold]

@qmfrederik, I I tried to add libintl.h file, but still get the same error.

@qmfrederik, I downloaded libintl.h file for #15751 from this this link.

@jkotas @qmfrederik @janvorli , so, could you help with the build process for android? Maybe there are some another important steps, that I forgot.

Any suggestions would very helpful.
Thanks.

[janvorli]

@meold I was on a paternity leave for the last month so I am sorry for low responsiveness. Now I'm back, so I can try to run the android build locally and find out how to fix the issue.

[meold]

@janvorli, thank you very much. Waiting for your reply.

[meold]

@janvorli, thank you for the for this pull request. CoreCLR builds fine now.
But I have another problem - with CoreFX (described here)

Any suggestions would very helpful.
Thanks.

[brianrob]

Looks like the coreclr build succeeded, so closing this.
