Comment(by nbruin):
The dirty {{{c::*cc-flags*}}} and {{{c::*ld-flags}}} are our own fault. In
the ECL spkg-install we have the lines:
{{{
CPPFLAGS="$CPPFLAGS -I$SAGE_LOCAL/include"
LDFLAGS="$LDFLAGS -L$SAGE_LOCAL/lib"
}}}
but we are adding paths there, not flags! It needs the include path to
find the boehm-gc headers, but our library search paths should already be
set up. Can we instead just do
{{{
C_INCLUDE_PATH="$SAGE_LOCAL/include"
export C_INCLUDE_PATH
}}}
If the library really needs to be mentioned here, perhaps also a
{{{
LIBRARY_PATH="$SAGE_LOCAL/lib"
export LIBRARY_PATH
}}}
but I think we can leave that one out. With this I get an ECL where we
obtain
{{{
> (require 'cmp)
> c::*cc-flags*
" -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -g -O2 -fPIC -Dlinux"
> c::*ld-flags*
" -lecl -lgmp -lgc -ldl -lm "
}}}
so no paths in the flags variables anymore! That just leaves figuring out
where best to change the values of the *ecl-...-directory* variables.
