Thanks, so https://gmplib.org/download/gmp/gmp-6.0.0a.tar.lz then https://gmplib.org/manual/Installing-GMP.html#Installing-GMP ?

Yes, that will install the latest version of GMP in /usr/local. However, you then need to use some special flags to link against it. Here's a snippet from my Linux compilation guide which modifies makefile.unix.

Code:

cp makefile.unix makefile.my
sed -i -e 's/$(OPENSSL_INCLUDE_PATH))/$(OPENSSL_INCLUDE_PATH) \/usr\/local\/include)/' makefile.my
sed -i -e 's/$(OPENSSL_LIB_PATH))/$(OPENSSL_LIB_PATH) \/usr\/local\/lib)/' makefile.my
sed -i -e 's/$(LDHARDENING) $(LDFLAGS)/$(LDHARDENING) -Wl,-rpath,\/usr\/local\/lib $(LDFLAGS)/' makefile.my

After that run "make -f makefile.my clean" and then "make -f makefile.my".

Also, it's possible to check that you're using your own custom libgmp by typing "ldd primecoind". The output should say something like this:

Code:

libgmp.so.10 => /usr/local/lib/libgmp.so.10 (0x0000003822600000)

That means it's using the libgmp installed in /usr/local.

Thanks, even without the changes, I have:
libgmp.so.10 => /usr/local/lib/libgmp.so.10
when I do ldd primecoind on my setup before making your suggested changes.
Does that mean it's using the latest version?

Here is a little script I made:

wget http://sourceforge.net/projects/primecoin-hp/files/0.1.2-hp12/primecoin-0.1.2-hp12.tar.bz2/download

tar jxf download

cd primecoin-0.1.2-hp12/src

cp makefile.unix makefile.my
sed -i -e 's/$(OPENSSL_INCLUDE_PATH))/$(OPENSSL_INCLUDE_PATH) \/usr\/local\/include)/' makefile.my
sed -i -e 's/$(OPENSSL_LIB_PATH))/$(OPENSSL_LIB_PATH) \/usr\/local\/lib)/' makefile.my
sed -i -e 's/$(LDHARDENING) $(LDFLAGS)/$(LDHARDENING) -Wl,-rpath,\/usr\/local\/lib $(LDFLAGS)/' makefile.my

make -f makefile.my USE_UPNP=-
