I add output line number for found error place.


Why I not get human readable error messages if CURLOPT_ERRORBUFFER point to 
buffer for error message?


libcurl *may* store error message there - which is explained by the man page.

A slightly better approach for that macro would be to check for a zero-length 
string there and if so, use curl_easy_strerror() to get a decent message to 
show. Or just show the error code.

Hello!
I think I found problem.
CurlFTPFS set CURLOPT_FTP_SSL option, but I buld curl without SSL support.
I not understand another - CurlFTPFS set CURLOPT_ERRORBUFFER to 
error_buf (static char error_buf[CURL_ERROR_SIZE]) and use follow define 
for set curl options:

#define curl_easy_setopt_or_die(handle, option, ...) \
  do {\
CURLcode res = curl_easy_setopt(handle, option, __VA_ARGS__);\
if (res != CURLE_OK) {\
  fprintf(stderr, Error setting curl: %s (%d)\n, error_buf, 
__LINE__);\

  exit(1);\
}\
  }while(0)
I add output line number for found error place.
Why I not get human readable error messages if CURLOPT_ERRORBUFFER point 
to buffer for error message?

Yes, this is problem with curlftpfs, but may be you help me increase curl 
output?


CURLOPT_VERBOSE and CURLOPT_DEBUGFUNCTION are fairly good ways to get info out 
from libcurl.

Hello, Daniel!
I found what CURLOPT_VERBOSE used in curlftpfs:
$ grep CURLOPT_VERBOSE -rnI -C1 .
./ftpfs.c-1544-  if (ftpfs.verbose) {
./ftpfs.c:1545:curl_easy_setopt_or_die(easy, CURLOPT_VERBOSE, TRUE);
./ftpfs.c-1546-  }

Why I not get verbose output if this options in use?

I think you'll have to ask the ftpfs developers that.
