-Say you want to try running file system server ([[`ext2fs`|translator/ext2fs]],
-[[`jfs`|translator/jfs]], ...) against a modified version of
-[[`libpager`|libpager]] and debug the latter one using [[debugging/GDB]].
-
-Set the [[hurd/translator]] like this:
-
- $ settrans -fgap ↩
- jfs.img.i ↩
- /usr/bin/env ↩
- LD_LIBRARY_PATH=~tschwinge/tmp/hurd/hurd.ogi/build/libpager ↩
- "$PWD"/jfs.obj/jfs ↩
- "$PWD"/jfs.img
-
-Then, when starting GDB, start it like this (or use an equivalent method, of
-course):
-
- $ LD_LIBRARY_PATH=~tschwinge/tmp/hurd/hurd.ogi/build/libpager ↩
- gdb ↩
- ~tschwinge/tmp/jfs/jfs.obj/jfs 15436
