Crash when static link

[sheldonlyr]

This is source file:

#include <stdio.h>
#include <zlog.h>

int main(int argc, const char *argv[])
{
    if (dzlog_init("./zlog.conf", "test_rule")) {
        fprintf(stderr, "dzlog_init falied\n");
        return 1;
    }

    dzlog_info("info message");
    dzlog_error("error message");

    zlog_fini();
    return 0;
}

Build command:

gcc main.c -std=c99 -Wall -g -o example -lzlog -lpthread -static

This is configuration file:

file perms = 644

[formats]
test_format = "[%d.%ms] [%-5V] %m%n"

[rules]
test_rule.debug    "test.log"; test_format

gcc version:

Using built-in specs.

After build, run binary file, it crashed immediately.

Because

gcc main.c -std=c99 -Wall -g -o example -lzlog -lpthread -static

The -static would make libpthread be static linked, then your program would always crash.

If you want to static link zlog only, you probably could use this

gcc main.c -std=c99 -Wall -g -o example /path/to/libzlog.a -lpthread

Though it has been four years, hope someone still cares about this.
