Hi all,
I test the DSO sample from http://dev.ariel-networks.com/ on Linux and
it works fine. OK, now I would like to test my own little library.
Its header file, apr_dso_f.h contains this function:
static int f10(int p1);
and its source file contains these lines:
#include <apr_dso_f.h>
static int f10(int p1)
{
return p1*10;
}
It compiles fine with the following command:
c:\MinGW\bin\gcc.exe apr_dso_f.c
-I e:\src\c_cpp\apr_test
-shared
-o apr_dso_f.so
I added the folder containig the apr_dso_f.so file to the PATH
variable so the following test program does not complain about anything:
#include <stdio.h>
#include <stdlib.h>
#include <assert.h>
#include <apr_general.h>
#include <apr_dso.h>
int main(int argc, const char *argv[])
{
apr_status_t rv;
apr_pool_t *mp;
const char fname[] = "apr_dso_f.so";
apr_dso_handle_t *dso_h;
/*typedef int (*f10_t)(int x);
f10_t f10;*/
apr_initialize();
apr_pool_create(&mp, NULL);
if ((rv = apr_dso_load(&dso_h, fname, mp)) != APR_SUCCESS) {
goto error;
}
/*if ((rv = apr_dso_sym((apr_dso_handle_sym_t*)&f10, dso_h,
"f10")) != APR_SUCCESS) {
goto error;
}
printf("%d\n", f10(12));*/
apr_dso_unload(dso_h);
apr_pool_destroy(mp);
apr_terminate();
return 0;
error:
{
char errbuf[256];
apr_strerror(rv, errbuf, sizeof(errbuf));
printf("error: %d, %s (%s)\n", rv, errbuf, fname);
apr_dso_error(dso_h, errbuf, sizeof(errbuf));
printf("dso-error: %d, %s (%s)\n", rv, errbuf, fname);
}
apr_terminate();
return -1;
}
After removing the comment, building it and running it, fails with the
following messages:
error: 720127, The specified procedure could not be found. (apr_dso_f.so)
dso-error: 720127, No error (apr_dso_f.so)
Can somebody help me?
Thank you,
