Re: [gentoo-user] Fwd: FontForge needs conversion from ISO-8859-1 to UCS2 - iconv (glibc-2.3.5-r2) does not support it on amd64

from that output:

open("/usr/lib32/gconv/UNICODE.so", O_RDONLY) = 4
read(4, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0 \5\0\000"..., 640) = 640
close(4)                                = 0
open("/usr/lib32/gconv/ISO8859-1.so", O_RDONLY) = 4
read(4, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\240\4\0"..., 640) = 640
close(4)                                = 0
---snip

So it opens a file, reads 640 bytes and closes it. Note the "/lib32".
Now this is my output, 32bit platform:

---snip
open("/usr/lib/gconv/ISO8859-1.so", O_RDONLY) = 3
read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\240\4\0"..., 512) = 512
fstat64(3, {st_mode=S_IFREG|0755, st_size=9720, ...}) = 0
mmap2(NULL, 12316, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0xb7de4000
mmap2(0xb7de6000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x1) = 0xb7de6000
---snip

So after reading the first 512 bytes, it mmap's a code section and a
data section into address space. Dynamic loading, I'd say (without
further debugging). So this seems to fail for you and I think the
"lib32" indicates that the 64bit glibc errorneously tries to load the
wrong modules for iconv.

Maybe you can temporarily move the lib32/gconv dir and soft link the
lib64/gconf in place of it to verify my assumption (it should work
then, but this is obviously not a solution as it will break 32bit
environment). You might want to file a bug into gentoo's bugzilla
(after searching for an existing one, of course).

Strange. Mine has:
---snip
module  ISO-8859-1//            INTERNAL                ISO8859-1       1
---snip

(whatever that means)
