install.sh Linux i386 - cannot find /lib/libc.so.6

[fische...@gmail.com]

Hi, a have problems installing CDT for Linux.

I have proper libraries in /Developer/Cocotron/1.0/PlatformInterfaces/
i386-ubutnu-linux [include and lib] - yes, libc.so.6 is here with cca
1.8MB file size (not a wrong link issue).

What is wrong?

Thanks, Petr Fischer

Sigh - why is the path in error message "/lib/libc.so.6" - is it bug
in cocotron build scripts? Correct path is "/Developer/Cocotron/1.0/
Linux/i386/gcc-4.3.1/i386-ubuntu-linux/lib"...

Hi,

You probably need to modify libc.so in the platform interface, this is
typically just some linker commands but they are absolute paths. Mine
looks like:

/* GNU ld script
Use the shared library, but some functions are only in
the static library, so try that secondarily. */
OUTPUT_FORMAT(elf32-i386)
GROUP ( libc.so.6 libc_nonshared.a )

The others might need to be modified like this too, libpthread.so is
another one.

(yea, this is a hassle but you only need to do it once and can
probably be fixed using sysroot in the gcc config)

SOLVED - thanks Chris!

Any chance you could post a patch to install.sh or provide a link to
where the mod could be?

Thanks!
