Tinycore 14.0 64bit: grub-mkrescue error
« on: April 23, 2023, 06:39:02 AM »
I'm using Tinycore 14.0 64bit
I download and loaded grub2-multi.tcz

Then i ran grub-mkrescue -o test.iso testfolder
but it gives errors as follows

Code: [Select]
grub-mkrescue: warning: cannot open directory `/usr/local/share/locale': No such file or directory
grub-mkrescue: warning: cannot open directory `/usr/local/share/locale': No such file or directory
Error converting to codepage 850 invalid argument
grub-mkrescue: error: `mformat` invocation failed

Can someone please tell me how to fix this?
Thanks

What happens if you symlink it to /usr/share/locale?

Is the mtools extension loaded?

You could try loading glibc_gconv

Have you tried using getlocale to create a mylocale extension and rebooting?

No I haven't. But I tried grub-mkrescue using
Tinycore 13.1 64bit resulting the same error
Tinycore 12.0 64bit also prompts locale warnings but it continues and successfully created the iso.
So, I'm guessing it's not the locale issues.

Btw, It's very late at night now, I will probably try getlocale tomorrow.
Thanks for helping  :)

I ran into a similar error while trying to run "syslinux -i" in TC 14.0 Pure64:
Code: [Select]
$ sudo syslinux -i /dev/sdb1
Error converting to codepage 850 Invalid argument
Cannot initialize 'S:'
Bad target s:/ldlinux.sys
syslinux: failed to create ldlinux.sys

The short story is that this fixes the problem (run as root, after installing glibc_gconv.tcz):
Code: [Select]
cd /usr/lib/gconv
mv gconv-modules gconv-modules.orig
cat gconv-modules.orig gconv-modules.d/gconv-modules-extra.conf > gconv-modules

Then "syslinux -i /dev/sdb1" runs without errors.

So /usr/lib/gconv/gconv-modules.d/gconv-modules-extra.conf, which is added by glibc_gconv.tcz, doesn't seem to be read by glibc in TC 14.

Extra info:
The error seems to come from the glibc iconv_open function, via mtools, and this page says: "If the iconv_open returns an error and sets errno to EINVAL, there is no known way, directly or indirectly, to perform the wanted conversion."
