Thank you for your prompt answer.
I tried to set the dynamic linker whith the -FL option too, but it
didn't help. Anyway, it seems to be a runtime hint, as you give a target
path as an argument, and I don't get the chance to reach this step, as
I can't produce any executable.
I read your doc, and didn't see anything else that could improve the
matters.
Also note step 8 it is very treacherous.
Did not change anything... What are precisely the respective purposes of
cprt0.o & cprt21.o ?
The 10th step can nowdays (all versions after medium july) be done by
passing -XLAc=c,dl and -XLAgtk=gmodule,gtk or so. Same for step 12.
Note that in the 10th step I do three things, IIRC
- The -FL sets the place where the loader on the target should look for the
dnyamic linker.
- The -Xr causes it to also search /usr/lib for anything it needs.
OK, that has runtime effect, it won't break linking, then.
- The -Fl points to the directory where I stored the copies of the libs.
Note that I sometimes renamed the copied libs a bit to match the names it
searches.
I did that already, and the linker seems to find anything it searches for.
Also note this remark:
----
Making mistakes with renaming is not that bad, there will be chances to fix
it. Make sure all crt* and a file "libc.so" are available, otherwise
generating link.res will go wrong. (Yes, Peter, that was my fault :-)
----
In case you added parameter by parameter, clean, and try to build again with
all relevant parameters. The compiler on Linux makes some decisions based on
the existance of some of these files.
I tried all this, unsuccessfully, alas.
Clearly all symbols that ld claims are undefined are defined in
ld-linux.so.2 (ld-2.3.6.so), but somehow ld doesn't find them....
But it does on Linux ! It is a priori the same, except this one is from
the cross-binutils (Well, indeed on linux I have ld 2.16.91 20060413
Debian Gnu/Linux; perhaps I should try to compile this one as cross-tool...)
Here is the link.res, if you can see some strange things from it.
