Cpan install failed on Android.

[RajDave-Dev]

Module: local::lib

Description

As we all know starting from Android 10 execution of binary is forbidden on Android. To overcome this problem we execute the binary with /system/bin/linker64 binaryname arguments. So the problem here is we add prefix of the linker64 to the binary that is executing but when perl try to get its own exe it always return the linker64 not perl I tried to fix this and repaced /proc/self/exe with the perl path but it didn't work. Steps to Reproduce

You can try this on termux on play store. Although I encountered this error in my app and also in termux.

Expected behavior

Should work as does in termux's GitHub varient. Perl configuration

Please could you show:

• How you built perl
• The simplest possible example of the error occuring - what code are you using to trigger and what's the output?

Is the fundamental problem that described by https://github.com/termux/termux-packages/wiki/Termux-and-Android-10 with an open-ended discussion under https://github.com/termux/termux-app/issues/2155 ?

Finally, how does this relate to local::lib please?

[RajDave-Dev]

1. I have built perl using the termux's package builder and ran command: ./scripts/run-docker.sh ./build-package.sh perl
2. Yes it is.
3. I don't think that it is really related to local::lib

Here is the output of cpan install local::lib

Here is the strace file cpan.txt

The problem I think is that when perl wants its own binary path but get the linker64 path, we use linker64 to execute every executable file so linker64 is the argv[0]. At first I was thinking that changing the /proc/self/exe to the perl binary path will solve the problem but it doesn't. So I searched for argv[0] and now I'm going to try changing the argv[0] to argv[1] because argv[0] is always the linker64, I hope that work.

Here Andio is my own app and same problem is occurring in termux's Play Store version.

[RajDave-Dev]

I tried changing the argv[0] to argv[1] but it doesn't work, I have changed only PL_origargv[] in all files.

[Leont]

I guess that means we should not be using the linux code for making $^X an absolute path on android then. I'd guess that's the procselfexe configuration option that needs to be disabled.

[RajDave-Dev]

How can we disable it?

[Leont]

How can we disable it?

That depends on how you build it. Adding a -Uprocselfexe argument to Configure might be enough, but you may also have to edit hints/linux-android.sh because that can also fiddle with it.

[RajDave-Dev]

Okay, I'll try it as well

[RajDave-Dev]

Now I'm getting this error while compiling 5.41.4, am I Missing any library? I'm not adding any libs while compiling perl

Now I'm getting this error while compiling 5.41.4, am I Missing any library?

Locale on Android has always been weird. I think @khwilliamson is better equipped to answer that question. I guess 3c45ca2e154f5fdc7ce2a0fdf51b192da3a1ae98 needs some refinement.

Those symbols if not available on the system are defined in perl_langinfo.h, which is included unconditionally in perl.h

I recall that Android's locale implementation was crippled, though that was a long time ago.

For the time being, to get you going sooner and avoid likely other locale-related issues,I suggest adding the following to your Configure options

-Accflags='-DNO_LOCALE'

You could generate a locale.i and send it to me, and/or look for a langinfo.h system hdr and send it to me

[RajDave-Dev]

Where is this langinfo.h or locale.i is located approximately?

I use termux's package builder so I somewhat don't know about it......

[RajDave-Dev]

I searched langinfo.h in android ndk, I don't find any.

[khwilliamson]

If you run make locale.i from the directory where you compile perl, it will create that .i file, which you can then send to me. Don't bother with langinfo.h for now; I may not need it.

But adding that Configure option should have gotten you (hopefully much) further along. The locale.i is just to help me figure out for the future what we can do to avoid this particular issue

[RajDave-Dev]

And yeah, I forgot to tell you that after using that configure option -Accflags='-DNO_LOCALE' it still failed with that locale error.

[RajDave-Dev]

I ran make locale.i after configuration and this is what I get make: *** No rule to make target 'locale.i'. Stop.

[khwilliamson]

Is there a config.h file in that directory. If so, please send it to me

[RajDave-Dev]

Okay. Here it is: config.txt

Renamed this file from config.h to .txt

[khwilliamson]

Attached is the file perl_langinfo.txt. You can just copy that on top of your existing file perl_langinfo.h Note the name change due to github limitations. perl_langinfo.TXT

[khwilliamson]

I hope this will get you past this problem. Let us know.

Run Configure, adding to your normal options, the flags -DDEBUGGING -Accflags='-DNO_LOCALE'. And send me the file that Configure generates config.sh Also, start the compilation again, and after it fails, run the following PERL_DEBUG_LOCALE_INIT=1 ./miniperl -DLv and send me the output

[RajDave-Dev]

Here is the config.sh file: config.txt

And running the command PERL_DEBUG_LOCALE_INIT=1 ./miniperl -DLv Gives Segmentation fault (core dumped) and no other output

[khwilliamson]

Try applying this patch setlocale.txt

[RajDave-Dev]

Still same error

I really need to see locale.i. In a log of compiling so far, there should have been a line gcc ... locale.c . Take that line and execute it separately, changing the gcc to gcc -E. And append > locale.i to the end. And send that to me.

[tonycoz]

Based on the earlier compilation command-line you should be able to get the preprocessed source with:

aarch64-linux-android-clang -DPERL_CORE --sysroot=/home/builder/.termux-build/_cache/android-r27b-api-29-v1/sysroot  -D__USE_BSD=1 -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -fPIC -Wno-unused-function -E locale.c >locale.i

You may also want the result of separate runs with -DNO_LOCALE and/or -DDEBUGGING

The Makefile.SH supplied with perl always generates a rule to build .i pre-processed files, so I wonder why it didn't work for you.

[RajDave-Dev]

Locale.i without any dlocale or debugging. Command:

aarch64-linux-android-clang -DPERL_CORE --sysroot=/home/builder/.termux-build/_cache/android-r27b-api-29-v1/sysroot  -D__USE_BSD=1 -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -fPIC -Multifunction -E locale.c >locale.i

File: locale.txt

Locale.i with -DNO_LOCALE

aarch64-linux-android-clang -DPERL_CORE -DNO_LOCALE --sysroot=/home/builder/.termux-build/_cache/android-r27b-api-29-v1/sysroot  -D__USE_BSD=1 -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -fPIC -Wno-unused-function -E locale.c >locale.i

File: locale.dnolocale.txt

Locale.i with -DDEBUGGING

aarch64-linux-android-clang -DPERL_CORE -DDEBUGGING --sysroot=/home/builder/.termux-build/_cache/android-r27b-api-29-v1/sysroot  -D__USE_BSD=1 -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -fPIC -Wno-unused-function -E locale.c >locale.i

File: locale.ddebugging.txt

[khwilliamson]

Add to your Configure options -Accflags=-DNO_POSIX_2008_LOCALE If running that fails in the same place, I need the config.sh and locale.i files. I only need the one combination of NO_LOCALE DEBUGGING and NO_POSIX_2008_LOCALE

[RajDave-Dev]

Here I have used this command to generate locale.i

aarch64-linux-android-clang -DPERL_CORE -DDEBUGGING -DNO_POSIX_2008_LOCALE -DNO_LOCALE --sysroot=/home/builder/packages/build/_cache/android-r27b-api-29-v1/sysroot  -D__USE_BSD=1 -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -fPIC -Wno-unused-function -E locale.c >locale.i

I have added the --Accflags but clang tells that it doesn't used this flag so I removed --Accflags and only put --DNO_POSIX_2008_LOCALE

Files: locale.i config.sh

[khwilliamson]

Several things:

There is only a single - before Accflags and before any of the -D words. Your comments indicate you used a double dash. But the command you used to generate locale.i looks good, and the file contents also look good to me.

Earlier, gcc was being used, and now clang. Is that deliberate?

And do you need threads? Generally, it's best to not use threads when trying to get things set up initially. They are a complication that can be dealt with later.

I think that if you use just the single dash, it will work a lot better, and you should get a lot further in your compilation. The previous version you sent me of locale.i, did not have -DNO_LOCALE actually specified. I don't think -DNO_POSIX_2008_LOCALE is necessary if plain -Accflags=NO_LOCALE is done correctly

You can examine the generated config.sh file and look at the line very near the top that starts config_args=. It should look very much like this

config_args='--target=aarch64-linux-android --with-cc=aarch64-linux-android-clang --with-ranlib=llvm-ranlib -Dosname=android -Dsysroot=/home/builder/packages/build/_cache/android-r27b-api-29-v1/sysroot -Dprefix=/data/data/com.raj.andio/files -Dsh=/data/data/com.raj.andio/files/bin/sh -Dld=aarch64-linux-android-clang -Wl,-rpath=/data/data/com.raj.andio/files/lib -Wl,--enable-new-dtags -Dar=llvm-ar -Duseshrplib -Doptimize=-O2 --with-libs=-lm -Accflags='-DNO_LOCALE' -DDEBUGGING -Uprocselfexe --keeplog --mode=target --target=aarch64-linux-android --targetarch=aarch64-unknown-linux-android'

[RajDave-Dev]

I use termux's package builder scripts. So i think that gcc is used to build perl to compile the perl files and then cross compile it, and if I forgot to mention that termux uses the https://github.com/arsv/perl-cross and then it copy all the files in perl-cross to the perl's source code.

This is the configure options:

CFLAGS= -D__USE_BSD=1 LDFLAGS= -Wl,-rpath=/data/data/com.raj.andio/files/lib -L/data/data/com.raj.andio/files/lib -lm /home/builder/packages/build/perl-latest/src/configure --target=aarch64-linux-android --with-cc=aarch64-linux-android-clang --with-ranlib=llvm-ranlib -Dosname=android -Dsysroot=/home/builder/packages/build/_cache/android-r27b-api-29-v1/sysroot -Dprefix=/data/data/com.raj.andio/files -Dsh=/data/data/com.raj.andio/files/bin/sh -Dld=aarch64-linux-android-clang -Wl,-rpath=/data/data/com.raj.andio/files/lib -Wl,--enable-new-dtags -Dar=llvm-ar -Duseshrplib -Duseithreads -Dusemultiplicity -Doptimize=-O2 --with-libs=-lm -DNO_LOCALE -DNO_POSIX_2008_LOCALE -DDEBUGGING -Uprocselfexe

Now I am trying without the -Duseithreads -Dusemultiplicity flags.

[RajDave-Dev]

I got the problem, the problem is with the perl-locale you provided. I skip copying the perl-locale file to the source-code's one and that segmentation fault is fixed but after some time it gives error about that locale.c error.

[khwilliamson]

I'm unsure which error you are referring to. If it is the ones like where it says

locale.c:6252:12: error: use of undeclared identifier '_NL_ADDRESS_POSTAL_FMT'
 6252 |       case _NL_ADDRESS_POSTAL_FMT:
      |            ^

then the solution is to use the perl_langinfo.h file I gave in https://github.com/Perl/perl5/issues/22627#issuecomment-2390376575

You did uncover a bug there, and that file should fix it.

[RajDave-Dev]

Sorry by mistake I told perl-locale but it's perl-langinfo.h file.

I was referring to this error https://github.com/Perl/perl5/issues/22627#issuecomment-2381104160 The stacktrace is the same to this one without the perl-langinfo.h you provided.

But perl-langinfo.h file you gave that triggers the miniperl's segmentation fault (core dump)

[khwilliamson]

Ok, with the perl_langinfo.h file I gave you that generates the strace problem, send me config.sh and config.i

[RajDave-Dev]

Here is the config.sh configsh.txt

Here is the config.h configh.txt

Here is the config.i configi.txt

Sorry I don't know how to generate config.i and i saw that there is config.h so I ran that locale.c >locale.i command

[khwilliamson]

I'm sorry. I meant I want locale.i But the config.sh file indicates that -Accflags=-DNO_LOCALE wasn't used in your Configure options. Did you forget, or is the cross compilation somehow stripping it. Without that, things aren't going to work

[RajDave-Dev]

Here is the command I used for creating locale.i

aarch64-linux-android-clang -DPERL_CORE -DDEBUGGING -DNO_POSIX_2008_LOCALE -Accflags=-DNO_LOCALE -DNO_LOCALE --sysroot=/home/builder/packages/build/_cache/android-r27b-api-29-v1/sysroot  -D__USE_BSD=1 -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -fPIC -Wno-unused-function -E locale.c >locale.i

But it's output is:

clang: warning: argument unused during compilation: '-Accflags=-DNO_LOCALE' [-Wunused-command-line-argument]

Here is the config.sh: config.sh.txt

Here is the locale.i: locale.i.txt

Here is the configuration command I have used to configure:

CFLAGS= -D__USE_BSD=1 LDFLAGS= -Wl,-rpath=/data/data/com.raj.andio/files/usr/lib -L/data/data/com.raj.andio/files/usr/lib -lm /home/builder/packages/build/perl-latest/src/configure --target=aarch64-linux-android --with-cc=aarch64-linux-android-clang --with-ranlib=llvm-ranlib -Dosname=android -Dsysroot=/home/builder/packages/build/_cache/android-r27b-api-29-v1/sysroot -Dprefix=/data/data/com.raj.andio/files/usr -Dsh=/data/data/com.raj.andio/files/usr/bin/sh -Dld=aarch64-linux-android-clang -Wl,-rpath=/data/data/com.raj.andio/files/usr/lib -Wl,--enable-new-dtags -Dar=llvm-ar -Duseshrplib -Doptimize=-O2 --with-libs=-lm -DNO_LOCALE -DNO_POSIX_2008_LOCALE -DDEBUGGING -Uprocselfexe -Accflags=-DNO_LOCALE

I have copied your perl-langinfo.h file to its destination. And the build fails with that miniperl segmentation fault error.

[RajDave-Dev]

Sorry I'm late, I was changing the installation prefix, because some other packages have some errors.
