Termux-packages: Clang is not working

[yubrajbhoi]

Problem description
Clang produces linking errors when compiling.

$ clang hello.c
/data/data/com.termux/files/usr/bin/ld: /system/lib/libunwind.so: undefined reference to `XzUnpacker_Code'
/data/data/com.termux/files/usr/bin/ld: /system/lib/libunwind.so: undefined reference to `XzUnpacker_Free'
/data/data/com.termux/files/usr/bin/ld: /system/lib/libunwind.so: undefined reference to `Crc64GenerateTable'
/data/data/com.termux/files/usr/bin/ld: /system/lib/libunwind.so: undefined reference to `CrcGenerateTable'
/data/data/com.termux/files/usr/bin/ld: /system/lib/libunwind.so: undefined reference to `XzUnpacker_Construct'
/data/data/com.termux/files/usr/bin/ld: /system/lib/libunwind.so: undefined reference to `XzUnpacker_IsStreamWasFinished'
clang-8: error: linker command failed with exit code 1 (use -v to see invocation)

Steps to reproduce
hello.c

#include <stdio.h>

int main(void) {
    printf("Hello\n");
    return 0;
}

$ clang hello.c

Expected behavior
Clang should be able to compile hello world code.

Seems like libunwind.a from NDK is required now. libunwind.a is already in ndk-sysroot.

[xeffyr]

Should be fixed with clang 8.0.1-4.

[yubrajbhoi]

@xeffyr Unfortunately it isn't. Can you please re-open this ? It is still showing the same error.

[xeffyr]

@yubrajbhoi Did you pkg upgrade'd ? I just verified on my devices and undefined reference error is gone.

[yubrajbhoi]

@xeffyr NVM it was my mistake. I was overriding libunwind. It is indeed fixed. Thank you.

I am getting similar error with clang-9:

[xeffyr]

@svimes This is a conflict between liblzma.so from Termux and from Android. You should force link with one in /system/lib64.

[svimes]

Thank you. You are right, the build was using the Termux copy of liblzma.so instead of the Android one.

[sane-987]

Plz help me with this
I have the issue while running the code:
$clang hello.c
/data/data/com.termux/files/usr/bin/aarch64-linux-android-ld: /system/lib64/libc.so: .dynsym local symbol at index 3 (>= sh_info of 3) /data/data/com.termux/files/usr/bin/aarch64-linux-android-ld: /system/lib64/libc.so: .dynsym local symbol at index 4 (>= sh_info of 3)
$ ./hello
bash: ./hello: Permission denied

[xeffyr]

@sane-987

1. You have issues with your ROM. Looks like /system/lib64/libc.so is corrupted but still usable.
2. Have you tried chmod +x ./hello ? And make sure that binary is not stored on /sdcard - execution permissions are disabled at this location.

[sane-987]

I've stored everything in internal
While performing chmod the operation is not permitted

[xeffyr]

I've stored everything in internal
chmod the operation is not permitted

Ensure your "internal" path is exactly

/data/data/com.termux/files/home

[sane-987]

Yes,it is
But still operation is denied

[sane-987]

@xeffyr thankyou it work after giving permissions :chmod +x ./hello.c

[MonAaraj]

Hi, I have the same error on my phone which is an android with clang 9, here's the error:

I've tried the chmod solution but it silently succeded without executing the file, and i dont know what to do to solve the liblzma.so solution, I might have a corrupted libc.so, can i redownload it to fix it or something?
