glibc-for-termux support 32bit arm and bug fixes

[ExtinctDrift19]

glibc 32

[Maxython]

glibc-for-termux will support all architectures, it's just a matter of time. So I understand what you mean by 32bit - arm architecture (armv7)? If yes, support for this architecture will not appear soon, since I do not have a device with arm.

[ExtinctDrift19]

Yes

can i help you with compiling for arm since i have a armv8l (but armv7 compatible) device with termux?

bruh its my device but if you have smth like that cool

Hi all. Now you can install glibc packages for armv7 architecture and experiment with packages for compiling in termux (note: in the termux section, not all packages are configured to compile in armv7).

after running gcc i got this bad sys call

and heres a bit of gdb in case you need it

[ghost]

after running strace i got this, weird

[Maxython]

Thanks for reporting the bug. I'll fix it soon and update the package archive in the release.

Is it just gcc or all glibc commands not working?

[ghost]

yep

[Maxython]

@Randomxdp, I need you to do the following:

• Install the https://github.com/torvalds/linux/blob/master/samples/vfs/test-statx.c file
• Compile it via clang (bionic)
• Run it (./a.out test-statx.c) and send me the result of running it.

I need this so that I understand whether you have a statx system call (according to the bionic system call standard, it must exist - https://android.googlesource.com/platform/bionic/+/master/libc/SYSCALLS.TXT#214).

[ghost]

my luck.

[Maxython]

Now, I would like to get the result of the termux-info command. And also try running some glibc commands with proot (for example: proot gcc).

[ghost]

termux-info

and proot fixes it?

[Maxython]

Similar case: libuv/libuv#2282 (I left it for further action)

[Maxython]

@Randomxdp, install this glibc and try to compile something based on gcc-glibc.

wget https://github.com/Maxython/glibc-for-termux/files/9738900/glibc-2.36-1-armv7.zip
unzip glibc-2.36-1-armv7.zip
proot --link2symlink pacman -U glibc-2.36-1-any.pkg.tar.xz

glibc-2.36-1-armv7.zip

[ghost]

when trying to build with pacman it couldnt verify the signature of binutils, (the package i tried to build) but the sha suceeded and this is a screenshot of my attempt to run gcc and also some debugging info

[Maxython]

The result of strace is not fully shown here. Can you show the full or end result of strace?

[ghost]

[Maxython]

@Randomxdp, now try using this glibc.

glibc-2.36-1-armv7.zip

After you install it, you must compile one program written below based on gcc-glibc and send me the result.

#include <stdio.h>
#include <time.h>
#include <fcntl.h>

int main () {
        struct timespec tp;

        if (clock_gettime(CLOCK_REALTIME, &tp) == -1) {
                perror("clock_gettime");
        }
        else {
                printf("clock_gettime success: %ld\n", tp.tv_nsec);
        }
        return 0;
}

this strace was big so i made it as a video

[Maxython]

Run this

gcc test.c -c test.o
strace ld -o test -dynamic-linker $PREFIX/glibc/lib/ld-linux-armhf.so.3 $PREFIX/glibc/lib/crt1.o $PREFIX/glibc/lib/crti.o -lc test.o $PREFIX/glibc/lib/crtn.o

[ghost]

here

[Maxython]

Bruh, you didn't copy the ld command all the way.

[ghost]

i forgor, anyways

[Maxython]

@Randomxdp, install this glibc.

glibc-2.36-1-armv7.zip

After that, try to compile the last file and run it (send the result).

[Maxython]

@Randomxdp, try to do the same but only with this glibc.

glibc-2.36-1-armv7.zip

[ghost]

[Maxython]

Great, you now have a working glibc (in theory). As a test, try compiling a program that doesn't require additional glibc libraries (for example, vitetris).

[ghost]

yep, its working, thank you!
