Openmoko에서 i386-linux-user 모드로 동작시키자. <아직도 미해결>
1. /lib/i386-linux-user 폴더를 만든다.
(편의상 lib에 만들었지만, 추후에는 /usr/local/lib으로 갈 예정)
mkdir /lib/i386-linux-user
2. 필요한 library를 복사한다.
ld-2.10.1.so libgcc_s.so.1 libnss_nis-2.10.1.so
libBrokenLocale-2.10.1.so libm-2.10.1.so libnss_nisplus-2.10.1.so
libSegFault.so libmemusage.so libpthread-2.10.1.so
libanl-2.10.1.so libnsl-2.10.1.so libresolv-2.10.1.so
libc-2.10.1.so libnss_compat-2.10.1.so librt-2.10.1.so
libcidn-2.10.1.so libnss_dns-2.10.1.so libthread_db-1.0.so
libcrypt-2.10.1.so libnss_files-2.10.1.so
libdl-2.10.1.so libnss_hesiod-2.10.1.so
등등...
cp /lib/libm* ./
cp /lib/libBrokenLocale* ./
cp /lib/libSegFault.so ./
cp /lib/libanl* ./
cp /lib/libc* ./
cp /lib/libdl* ./
cp /lib/libgcc_s.so.1 ./
cp /lib/libn ./
cp /lib/libn* ./
cp /lib/libpthread* ./
cp /lib/libresolv* ./
cp /lib/librt* ./
cp /lib/libthread_db ./
cp /lib/libutil ./
cp /lib/libutil* ./
3. 링크 파일 생성한다.
ln /lib/i386-linux-user/ld-2.10.1.so /lib/ld-linux.so.2
4. 에러 발생
a.out: error while loading shared libraries: lle: cannot open shared object file: No such file or directory
- ld-linux.so.2를 실행시키는 것은 성공,
# ./qemu-i386 -E LD_LIBRARY_PATH=/lib/i386-linux-user/ /lib/ld-linux.so.2
Usage: ld.so [OPTION]... EXECUTABLE-FILE [ARGS-FOR-PROGRAM...]
You have invoked `ld.so', the helper program for shared library executables.
This program usually lives in the file `/lib/ld.so', and special directives
in executable files using ELF shared libraries tell the system's program
loader to load the helper program from this file. This helper program loads
the shared libraries needed by the program executable, prepares the program
to run, and runs it. You may invoke this helper program directly from the
command line to load and run an ELF executable file; this is like executing
that file itself, but always uses this helper program from the file you
specified, instead of the helper program file specified in the executable
file you run. This is mostly of use for maintainers to test new versions
of this helper program; chances are you did not intend to run this program.
--list list all dependencies and how they are resolved
--verify verify that given object really is a dynamically linked
object we can handle
--library-path PATH use given PATH instead of content of the environment
variable LD_LIBRARY_PATH
--inhibit-rpath LIST ignore RUNPATH and RPATH information in object names
in LIST
--audit LIST use objects named in LIST as auditors
- 왜 실행에 에러가 발생하는 것일까?
5. glibc를 학습해봐야 하나..ㅠㅠ
eglibc (2.10.1-0ubuntu15)
glibc-2.10.1 installation
The GNU C Library Reference Manual
- 에러 메시지 내용은 찾았다.
(lle는 아직 몿찾음.)
po 파일에 있기는 있는데.
po 파일에 대한 간단한 설명
0. 학습이
필요하다.
