compiling mprime

[ATH]

I installed Ubuntu 64bit in VMware and have tried to compile mprime but I need some help.

First I corrected some issues with wrong path to curl.h and gwnum.a. I'm using the gwnum.a in gwnum/linux64 dir and the gwnum.ld in gwnum dir. I also installed g++-multilib because it was missing lstdc++.

Now I get a lot of "undefined reference" but I don't understand the final error message:

That means the code is making function calls, but the linker (ld) can't find any code that's designated as being those functions. (Or it could it can't find some global variables or something.)

However, I don't know enough to tell you where to get what's missing. In my own attempts to compile it previously, I ran into different problems, such as not having the CURL library and other things. I didn't get these ld errors.

[ATH]

Yeah I also had missing curl.h but I downloaded it and corrected the link to the curl.h file.

[Batalov]

Some (or most) of your missing symbols refer to gwnum.a
There are precompiled libs included. You gotta copy an appropriate one to the dir where linking happens.
cd ..
find . -name gwnum.a

[Prime95]

The gwnum library you copies only has the assembly code object files. You need to compile the C code.

Go to the gwnum directory and type 'make -f make64' to create the "real" gwnum.a.

Thanks.

My problem now is curl. I have tried downloading it and compiling it, and also downloaded it from Ubuntu Software Center but I still get:

I'll probably give up soon, I just don't know enough about Linux to do this.

What version of Ubuntu and curl are you using ?

And it's usually harder to assemble the pieces you need for compiling a program (its "build dependencies") on Windows than on *nix

[alexvong1995]

I have the same problem but now I have made it!!!

It cannot connect to Primenet but I think (not tested yet) you can use Submission Spider instead.
I am using Debian Jessie. I think it will also work for Ubuntu since it is Debian-based.

First, you have to have g++ installed.

Then, follow George's instruction to create gwnum.a

After that, check if you have libcurl.so in /usr/lib/
if not, following instructions on this page to install curl,
or you could install a package but I can't find one.

Next, go to <your_source_directory>/linux64/makefile
On the line

LIBS = ../gwnum/gwnum.a ../gwnum/gwnum.ld -lm -lpthread -Wl,-Bstatic -lcurl -Wl,-Bdynamic -lrt -lstdc++ -ldl

change

-Wl,-Bstatic -lcurl

to

-Wl,-Bdynamic -lcurl

With this change, you tell the linker to link against the dynamic library libcurl.so instead of the static library libcurl.a which is causing problems.

Finally, 'make' will do everything.

[alexvong1995]

I have done some P-1 double-checks. I think you cannot submit them with Submission Spider. So forget what I have said.

Anyway, I have written a quick and dirty python script just enough to report P-1 tests with no factor found. I don't know the network stuff well enough to use the PrimeNet API so I am only auto-filling form for manual testing. You will need username and password for it to work. Also, you need to install mechanize library for python2. I write it just because today is Friday.

[alexvong1995]

Fix the code to use a table check to get the fft size based on http://www.mersenne.org/report_benchmarks/

The main use of the script is to disguise the results as results from cudapm1 to silent the

Error: Missing checksum. Correct the problem or email results to woltman@alum.mit.edu

error. This is due to the security code being missing from the self-compiled version of mprime.
