OpenEuphoria

1. euphoria on Ubuntu Linux

New install of euphoria downloaded from rsd for a linux platform. Platform is Ubuntu Linux using bash shell. Followed instructions for installing. exu refuses to run (from command line terminal). At first I thought it was a problem related to the exu executable file as the error message was "no such file or directory" (command issued from bash while in directory containing exu -> ./exu or ./exu file.ex). After many hours of working on this problem I am beginning to think that it has to do dynamic link libraries or the lack of them as if I run it under gdb because gdb tells me that it is unable to find the dynamic linker breakpoint. ldd tells me that it is NOT a dynamic executable; however, file tells me that it IS a dynamically linked program. I have done all the obvious things. Any thoughts greatly appreciated.

$ ldd ./eui 
        linux-gate.so.1 =>  (0xb803e000) 
        libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7ffa000) 
        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7ff6000) 
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7e92000) 
        /lib/ld-linux.so.2 (0xb803f000)

Further information:

file gives:

exu: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.8, dynamically linked (uses shared libs), not stripped

---

gdb answer:

(gdb) run Starting program: /home/jd/euphoria/bin/exu /bin/bash: /home/jd/euphoria/bin/exu: No such file or directory /bin/bash: /home/jd/euphoria/bin/exu: Success

Program exited with code 01. warning: Unable to find dynamic linker breakpoint function. GDB will be unable to debug shared library initializers and track explicitly loaded dynamic code. You can't do that without a process to debug.

---

ldd yields:
not a dynamic executable

---

The error message is NOT coming from the shell. It appears to be coming from the loader or the program itself. Is there something required by exu to run on linux that is assumed to be there?

---

Time marches onward toward the inevitable end.

ls -l /lib/ld*.so 

uname -a

Got it!

I replaced Ubuntu 8 with Ubuntu 9 and the problem dissappeared. Apparently a subtle bug.

Thanks for your kind help
