Re: [Gcl-devel] Maxima GCL buld trouble

[Camm Maguire]

Hi Vadim!  If you want to try a static libc, which should fix this, do
this in linux.defs:

# under redhat 6.1 and slackware 7.0 we needed to have this
# link be static, but should be ok with the fix to unixport/rsym_elf.c
LDCC=${CC} -static
######  comment this out for static libc link ###### LDCC=${CC}

ldd on the binary should indicate that all libs are statically linked
in. 

I'd be interested to know of the details of your experience here.  We
will doubtlessly have to bring this up with the emacs people.

I'm assuming you are doing the 'traditional' maxima gcl build,
i.e. doing the save-system after the .o files have been loaded.  This
should be fine given your description of the problem.  But just to let
you know, there is an --enable-gcl-altlink option to the maxima
configure, which will effectively use ld to link in the .o files into
raw_maxima via compiler::link, and then run the interpreted maxima
init code, and save the system at this later stage.  This is required
on machines where GCL currently cannot relocate .o files into the
running image (mips(el), hppa, ia64, and alpha), but can be run
anywhere.  Doesn't sound like you need this though.

Take care,
