Hello,
I'm attempting to compile CLN 1.1.13 using GCC 3.4 (inside scratchbox
using qemu which allows GCC to be a native ARM compiler). I am
compiling for the Nokia N800.
I'm compiling with the following configure command:
./configure --with-gmp --prefix=/usr
and with the following env vars:
CPPFLAGS="-DNO_ASM"
CXXFLAGS="-O2 -fno-exceptions -finline-limit=1000 -mfpu=vfp
-mfloat-abi=softfp"
I get the following error (trimmed as the preceeding command is very long):
/bin/sh ../libtool --mode=link g++ -o libcln.la -rpath /usr/lib
-version-info 4:2:0 -lgmp -objectlist libcln.objectlist
g++ -shared -nostdlib

I did a search of the mailing list archives and could only find this
mentioned for MinGW. There was no solution as far as I could tell, but
some talk of --param *inline* options that might make a difference. The
installation instructions say the following: "If you use g++ on OSF/1
or Tru64 using gcc-2.95.x, you should specify `--disable-shared'
because of linker problems with duplicate symbols in shared
libraries.", which sounds like my problem, though obviously on a
different platform & compiler version.
I have tried altering -finline-limit (removing it, and changing the
value to 10000), but to no avail, I still have the problem.
I am trying to compile Qalculate, and even if I compile CLN to be a
static library, I get linking errors due to the multiple functions when
compiling libqalculate.
Is there any way around this problem? Any other -finline*/--param
options I could try, etc., or any other ideas?
Many thanks,
Simon
P.S. I'm not subscribed to the list, but can do so if needed.
