You compile a 64 bit library "-m64 -mptr64 ...:"

but you link against 32 bit gcc libraries ("ELFCLASS32").

To resolve this:

a) configure with "ABI=32" to get a 32 but gmp


b) include the 64 bit libs of gcc in $LD_LIBRARY_PATH - on my sparc box
for exmaple that would be

/usr/local/gcc-3.4.2/lib/sparcv9/  [notive the "v9"]

The 32 bit libs are in "/usr/local/gcc-3.4.2/lib/"

Hope this helps,


PS: Can this problem be added to the Manuel/FAQ because it crops up at
least once or twice a month. I know, if people were to read the manual
these questions would never be asked, but unfortunately we have to live in
reality. My apologies if this is already in the manual and I was to dim to
look for it ;) Googling for "gmp ELFCLASS32" also solves the problem
