[Fwd: Debugging execve problems]

[Svante Signell]

Hi,

Looks like this mail did not arrive to the ML. I'm resending and people
interested can contact me for the non-stripped iconx executable (1MB),
or build yourself from the Debian source.

Hi,

Attached are test programs and a partial gdb session to hunt down the
problems with execv for the icon package:

Without . in PATH:
==================
 ./a.out
error in startup code
/dev/fd/3: can't read interpreter file header

With . in PATH:
===============
PATH=.:$PATH; ./a.out
                                                        Hello, hello.

Test programs: test_execve.c (parts of src/icont/tunix.c)
gcc -g test_execve.c -> a.out
Icon executable: iconx
icon application program (source): hello.icn
icon application program (executable): hello
gdb session (results up to now, not complete!): debugging_execve
