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".

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

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/$(LDHARDENING) $(LDFLAGS)/$(LDHARDENING) -Wl,-rpath,\/usr\/local\/lib $(LDFLAGS)/' makefile.my

make -f makefile.my USE_UPNP=-

Anyone do or have a benchmark to compare http://primegpu.com http://rapidprime.com as GPU vs CPU on Primecoin? It would be interesting to see whether it's profitable to do CPU anymore and how profitable with GPU.

I'm going to guess it is (or will soon be) roughly equal to the more profitable scrypt coins but 10-20% less profitable than vertcoin (on highly optimised cards reaching their limit for scrypt-n). Everything has its way of working out...

I'm updating everything and fine tuning a pair of 3770 processors, using hp12.  Will see how a month of them going goes, and the electric cost.
Wondering this as well, GPU miners could spike the price though, hash rate goes up, so does coin value generally as does market cap.

Love to know the stats or benchmark to see which one is better, let me know!

please update hp12 cause it uses vulnerable to heartbleed bug openssl v1.0.1e

AFAIK it just uses the libs, so you'll be fine by upgrading openssl and restarting primecoind.
No changes required on primecoind's side (unless you have used SSL for your rpc calls)

I'm working on a new release with updated OpenSSL. AFAIK, there's two ways to exploit the OpenSSL bug in the wallet:
1.) Using -rpcssl with a wallet daemon. This turns the RPC port into an SSL server which can be exploited. If the port is open to the internet, your wallet may be compromised.
2.) Opening payment protocol links which makes the wallet connect to an SSL server. If the server is malicious, your wallet may be compromised. So don't open any links starting with primecoin: .

Hi, Mikaelh.

I did a partial double spend by accident since I have installed Primecoin-Qt on two computers. Do you know how long the transaction will be in the memory pool and block my funds?

HP13 released! Download links are on the first page. Links point to my own server because SourceForge is being especially slow for me.

Changes:
 * Binaries compiled with OpenSSL 1.0.1g which addresses the Heartbleed vulnerability
 * Faster blockchain download
 * Bonus: Also compiled with GMP 6.0.0a

Mac OS X version will be delayed because it failed to build this time.

Hmm, how well will this work with my i3?

GMP has optimized assembly for several processors. I'd expect it to give decent performance on an i3.

Simmer down TheSwede75...

I've always loved the term " simmer down " . Lol

yeah, me too. It's a soothing/relaxing and non-threatening/defensive term. Crisp and clear.

I fixed the OS X build and it's now available for download.

Sadly seems CPU mining is quite unprofitable(Unless you have the gear already and free electricity, but then what isn't profitable at that point).  The 3770 processors(5) only hit 1 block since my last post.
I had a 4770 pointed to beeeeer and I got around .05 XPM a day, which seems about right?

Though it's hard to judge, next month could have hit a ton of blocks, but seems these CPU's will need to find a new purpose.
CPU coins become GPU, and Scrypt now belongs to ASICs.
Wonder what things will be like a year from now.

I'm still running them though for now, will update if luck changes.

If you want to do profitable CPU mining, my tips are:

- Have a lot of hardware ready to go, sourced as cheap as you can
- Free / leached electricity helps. By leached I mean at work or low cost tarrifs, not coathangering your power box
- If you must pay for power, use newer CPU with fab sizes not larger than 34 nm. Newer CPU are amazingly more efficient.
- Avoid buying old servers from eBay or site auctions. Yes they're extremely cheap but they'll always be disappointingly slow, inefficient, and noisy.

Lastly but most importantly, you must sink a lot of time into researching and looking for new CPU coins, which means browsing the altcoin forum daily. You have to get onto the new coins as soon as they're out as that is always where the profits lay in the long run. The time you spend doing this and tweaking mining software/hardware may not ever exceed your profits if you put a value on your time.

Unless you are lucky your efforts will probably be in vain when compared to margins from scrypt/scrypt-n/SHA-256 coins and hardware.
