Is there going to be a Linux application in the future?

Will appear if you tell me how to compile PARI/GP for Linux.

Maybe termit knows this.
But it still has problems running on Windows.

I found a quote from Demis

Для винды - да.
Для линукса - я уже много раз писал что, это немного хитрее.
И нужно смотреть как сделать для линукса стандалоне версию...
(просто для винды она УЖЕ сделана)

See

And one more quote from Demis

Повторюсь еще раз:
С боинк-клиентами так не получится (не важно какая система).
Они должны получать готовое приложение.
Со всеми внедренными библиотеками.

Это обязательное условие, т.к. на клиенте может оказаться такая библиотека,
но не той версии под которую написано приложение.
Одна из них это gmp (на ней-же основана и primesieve, на которой работает приложение SPT).
Это объяснял еще в июле кажется.

При сборке pari/gp потребуется обновление gmp.
И это проблема.
Напоминаю, что в июле 2023 устанавливал на сервер pari/gp.
Он обновил все модули gmp.

По этой причине полетела вся сборка по SPT и не только само приложение,
но и ассимилятор, и прочие программы, что необходимы для нормальной работы проекта.

Было потрачено 3 или 4 дня,
чтобы найти все хвосты "от неправильной" (то есть другой) версии
и вернуть все в рабочее состояние.

yes, now that the project is open to the public, we're waiting for a linux application.

The PARI/GP site has instructions for compiling and running on Linux. When I worked with you before (assuming this is the same application) there was another program (symtuples.exe) required that was written specifically for Windows that needed to be re-written for Linux. PARI/GP itself works fine on Linux.

See:
I compiled the PARI/GP program for Linux and started running ...test_4 through ...test_11 simultaneously on one of my larger systems. the ...test_6 program ended after 7 hours. Programs 4,5,7,8,9,11 continue to run (11 hours so far).
Here is the output from the results_6.txt file:

Thanks.
I remember that.

I think termit will try to make a Linux app when it finishes launching Windows.

Dear project participants!

termit needs help to launch the Application for Linux.

Who can help, please write a PM to me or termit.

Dear project participants!

Let's think together how to launch the Application for Linux.

Here's what we need.

1. The gp.exe program, which should work in Linux.

We take this program from the official page
https://pari.math.u-bordeaux.fr/download.html

2. A working program that performs calculations.

This program is published here
https://boinc.mak.termit.me/odlk2025/forum_thread.php?id=13&postid=52

3. A program that runs the gp.exe program and monitors its execution.

The code for this program in C++ is published here
https://boinc.progger.info/odlk/forum_thread.php?id=290&postid=14671

All these programs need to be adapted for Linux.

Who can help termit?

Maybe you have some thoughts.
Please share

Please, recommend other projects where the Linux Application works (if you participate in these projects and know well how they work).
I will write there too.
Maybe someone will respond.

Yes, that's the most important thing!

The program we need now is the same, the code for this program is published here

can you rewrite this code for Linux?

Maybe someone else can?

I asked a colleague from Italy about gp.exe for Linux.

He replied

I just find that pari/gp is officually in Ubuntu:
https://installati.one/install-pari-gp-ubuntu-20-04/

so one can download the linux executable with

sudo apt -y install pari-gp

termit
perhaps this will be useful to you.

My colleague from Italy Stefano Tognon rewrote the SymTuples.cpp program for Linux.

I publish this code

#include <iostream>
#include <assert.h>
#include <ctime>
#include <cstdio>
#include <cstring>
#include <unistd.h>
#include <sys/types.h>
#include <sys/wait.h>
#include <fcntl.h>

using namespace std;

#define CHECKPOINT_FILENAME "checkpoint.txt"
#define POLL_PERIOD 1.0

#define INPUT_FILENAME "in"
#define OUTPUT_FILENAME "out"

int read_checkpoint(int& percent_completed, double& cpu_time) {
    int nt;
    double c;

    percent_completed = 0;
    cpu_time = 0;

    FILE* f = fopen(CHECKPOINT_FILENAME, "r");
    if (!f) return -1;  // ERR_FOPEN equivalent
    int n = fscanf(f, "%d %lf", &nt, &c);
    fclose(f);
    if (n != 2) return 0;
    percent_completed = nt;
    cpu_time = c;
    return 0;
}

void write_checkpoint(int percent_completed, double cpu_time) {
    FILE* f = fopen(CHECKPOINT_FILENAME, "w");
    if (!f) return;
    fprintf(f, "%d %f\n", percent_completed, cpu_time);
    fclose(f);
}

int start_process_gp() {
    fprintf(stderr, "\nStarting child process 'gp' and waiting until process exits.\n");
    fprintf(stderr, "Command line : %s\n", "gp spt.txt");

    pid_t pid = fork();
    if (pid == -1) {
        perror("fork failed");
        return 1;
    }

    if (pid == 0) {
        // Child process
        execlp("gp", "gp", "spt.txt", (char*)NULL);  // Execute the command
        perror("execlp failed");
        return 1;
    } else {
        // Parent process
        int status;
        waitpid(pid, &status, 0);  // Wait for the child process to terminate

        if (WIFEXITED(status)) {
            fprintf(stderr, "Process gp finished with exit code %d.\n", WEXITSTATUS(status));
        } else {
            fprintf(stderr, "Process gp terminated abnormally.\n");
            return 1;
        }
    }

    return 0;
}

int main(int argc, char* argv[]) {
    int retval = 0;

    // Placeholder for BOINC options and status (adjust if needed for Linux)
    // In Linux, we might need to replace BOINC initialization code with an appropriate API for Linux
    // e.g., use the BOINC client tools in the Linux environment if required.

    retval = start_process_gp();
    if (retval) {
        fprintf(stderr, "Error starting process gp. Exiting.\n");
        return retval;
    }

    fprintf(stderr, "Program completed.\n");
    return 0;
}

The colleague then compiled an executable program from this code.
After that, he ran the test on Linux.
The test was successful.

I hope all this will help termit to run the Linux Application.

If you have any more questions, please write to me.

I sent you an archive that a colleague sent me.
The archive contains the source code of the SymTuplesLinux.cpp program and the executable program.

The working program spt.txt does not change.
