gelfload is Gregor's ELF loader. It is a usermode loader for ELF executables, used for two purposes: 1) Creating ELF environments on otherwise ELF-hostile platforms (e.g. Mac OS X and Windows) 2) Cros...
This is gelfload, a portable runtime ELF loader. It lets you use ELF on platforms that don't natively support ELF!
Some special properties of gelfload:
-
To integrate gelfload well into platforms that /do/ support ELF, gelfload ELF files should have their interpreter set to /usr/bin/gelfload-ld
-
gelfload ELF files may refer to gelfload .so files by their standard name, or they may use symbolic names to refer to host libraries:
- libhost_
refers to the library on the host, e.g. libhost_libc.so.6 or libhost_msvcrt.dll - libhost_.so refers to:
- if possible, all libraries loaded by gelfload in the host, including certainly at least libc
- otherwise, libc or the nearest equivalent, e.g. msvcrt.dll
- libloader_dl.0 refers to the loader's builtin library providing dlopen() and dlsym()
- libhost_
gelfload is still in development, and doesn't yet support all ELF relocations. Some tests are in test/. They're tested primarily on GNU/Linux, however the test named testdl uses only standard libc functions and should work on any host system (including e.g. Mac OS X).
