Well I may not be inclined right now to determine the define to be set. However i have this finding, this program a.c with the following code and compiled it with -m64 options and without the -m64 options (gcc compiler) i get different outputs for the sizeof(curl_off_t) bash-2.05# cat a.c #include <stdio.h> #include <curl/curl.h> int main() { printf("%d %d %d %d\n", sizeof(long), sizeof(int), sizeof(off_t), sizeof(curl_off_t)); } bash-2.05# gcc -o prog a.c bash-2.05# ./prog 4 4 4 4 bash-2.05# gcc -m64 -o prog a.c bash-2.05# ./prog 8 4 8 8 But when i try to compile the following ftpupload.c program with -m64 option, I get an error like this... What does this mean?? Is it that when i ran the make script while installing libcurl, I didnt use -m64 option?? bash-2.05# gcc -m64 -o prog -I/usr/local/include -L/usr/local/lib -lcurl -L/usr/local/ssl/lib -lssl -lcrypto -ldl -lsocket -lnsl -lz ftpupload.c ld: fatal: file /usr/local/lib/libcurl.so: wrong ELF class: ELFCLASS32 ld: fatal: File processing errors. No output written to prog collect2: ld returned 1 exit status bash-2.05# cat ftpupload.c #include <stdio.h> #include <curl/curl.h> #define TRUE 1 #define LOCAL_FILE "a.txt" #define REMOTE_URL "ftp://bridge/a.txt" struct FtpFile { char *filename; FILE *stream; }; int my_fread(void *buffer, size_t size, size_t nmemb, void *stream) { struct FtpFile *out=(struct FtpFile *)stream; if(out && !out->stream) { /* open file for reading */ out->stream=fopen(out->filename, "rb"); if(!out->stream) return -1; /* failure, can't open file to read */ } return fread(buffer, size, nmemb, out->stream); } int main(int argc, char **argv) { CURL *curl; CURLcode res; char passwd[] = "hemant:sample"; struct FtpFile ftpfile={ "a.txt", /* name to store the file as if succesful */ NULL }; printf("%ld\n", sizeof(curl_off_t)); printf("%ld\n", sizeof(off_t)); /* In windows, this will init the winsock stuff */ curl_global_init(CURL_GLOBAL_ALL); /* get a curl handle */ curl = curl_easy_init(); if(curl) { /* enable uploading */ curl_easy_setopt(curl, CURLOPT_UPLOAD, TRUE) ; /* specify target */ curl_easy_setopt(curl,CURLOPT_URL, REMOTE_URL); curl_easy_setopt(curl, CURLOPT_USERPWD, passwd); curl_easy_setopt(curl, CURLOPT_FTP_SSL, CURLFTPSSL_ALL); /* Define our callback to get called when there's data to be read */ curl_easy_setopt(curl, CURLOPT_READFUNCTION, my_fread); /* now specify which file to upload */ curl_easy_setopt(curl, CURLOPT_READDATA, &ftpfile); curl_easy_setopt(curl, CURLOPT_INFILESIZE,(long)3); curl_easy_setopt(curl, CURLOPT_VERBOSE, TRUE); /* Now run off and do what you've been told! */ res = curl_easy_perform(curl); /* always cleanup */ curl_easy_cleanup(curl); } curl_global_cleanup(); return 0; } On Thu, 19 Jan 2006 Daniel Stenberg wrote : >On Thu, 19 Jan 2006, azad amm wrote: > >>Now, i am able to find out that curl_off_t is 32bit in my app, with printf("%d\n", sizeof(curl_off_t)); > >>How do i find out the sizeof curl_off_t in libcurl? > >It isn't that easy to probe, but from the output in your error case we know this.

In the curl headers, it tries to include the necessary files to find your system's off_t type and then curl_off_t is set to use that type. > >On all modern unixes, off_t is 64 bit.
