Re: FTP passive mode
Thanks a lot to all! Patrick Monnerat wrote: Be also aware that, in active mode, the server connects to the client: this means you may have problems along the network path with: - Firewalls (reverse data port must be open). - NAT (the real IP address of your client may not be seen as such by the server). - Port forwarding: inbound data connection requests should be redirected to your client if the later is on a LAN and the server in the outside world. That's why the active mode is pretty much deprecated nowadays. Mostly. When the server is behind a firewall/NAT with port forwarding, such as my friend's little Netgear NAS at home, depending on the router you might have to use active mode. (It's unfortunate if client and server are both in this situation, as neither active nor passive modes work then.) -- Jamie --- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
FTP passive mode
It is said in the docs that CURLOPT_FTP_USE_EPSV Pass a long. If the value is 1, it tells curl to use the EPSV command when doing passive FTP downloads (which it always does by default). And how can I connect to FTP without passive mode? --- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html

they are other - nothing works. They are according to the official

ultotal is never zero. When function is

{
printf(%f / %f (%g %%)\n, ulnow, ultotal, ulnow*100.0/ultotal);

everything works as it should be. The problem is when it returns

Re: Re: Re: Error 411 (Length Required) in post request with header, but header has Content-Length:
Solved. My error was because there is a symbol for a new line at the end of the auth string that I receive from YouTube in my prev POST request. --- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
Re: Re: Error 411 (Length Required) in post request with header, but header has Content-Length:
You should never need to specify the Content-Length header like
this--libcurl
takes care of that as necessary. In this case, you probably want
the
CURLOPT_POSTFIELDSIZE_LARGE option. Enable logging and you'll see
exactly
what headers are being sent out.
I try with or without Content-Length in my header - result is the
same. I'm trying to form post request as in the manual -
http://code.google.com/apis/youtube/2.0/developers_guide_protocol_direct_uploading.html#Direct_uploading
when I include CURLOPT_VERBOSE option I get such info. Maybe I form
POST request wrong? What is the right way to send POST request with
headers in libCurl?

Lots of errors when try ro use self built OpenSSL and lincUrl with it
I haven't give up yet on libcurl with OpenSLL! I built myself OpenSSL statically with the help of INSTALL.W32 and http://stackoverflow.com/questions/197444/building-libcurl-with-ssl-support-on-windows/7231376 So I receive libeay32.lib and ssleay32.lib. Then I've built libcurl following the instructions in INSTALL.W32 file in lubcurl folder for Visual C++. I receive libcurl.lib. Now I'm trying to use then in my project, but it's on MinGW with Eclipce.

RE: RE: Linker errors when statically compiled linking libcurl+openssl to my project
Looking at rand_win.c it uses CreateDCA, CreateCompatiableDC(), GetDeciceCaps() etc... which are defined in gdi32.lib. These are defined in ws2_32.lib. What libraries is your application linking against? I'm not a MinGW / Eclipse user but it looks like you will need to add gdi32.lib and ws2_32.lib to your project. ws2_32.lib was already linked, I added gdi32.lib. Errors decreased.

Re: Re: Re: Problem using static libraries libcurl with OpenSSL, minGW, Eclipse
As I was told on StackOverflow, maybe the openssl-libs I link against seem to be import-libraries. That means they only contain the information your code needs to call functions and then load and call the corresponding functions from the dll. So the problem is: although you link to static libs, the libs then load and use dynamic dlls. They are no real static libs. I downloaded them from http://www.shininglightpro.com/download/Win32OpenSSL-1_0_0d.exe , used .a-files in folder called MinGW. Maybe I took wrong files from wrong place? I need static OpenSSL libs --- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
RE: RE: RE: RE: Linker errors when statically compiled linking libcurl+openssl to my project
I just had to check MSDN for this one - and it says this function is defined in winmm.lib. I'm not too familiar with librtmp, so I just downloaded the source for it and checked out it's makefile which includes the following when building with mingw: -lws2_32 -lwinmm -lgdi32 Can you add -winmm and see if that decreases the number of errors by 1?

Problem using static libraries libcurl with OpenSSL, minGW, Eclipse
I downloaded compiled static libs of OpenSSL, from here - http://www.shininglightpro.com/download/Win32OpenSSL-1_0_0d.exe , this link is on the official cUrl site in Download page. I downloaded Zlib and compiled them, then I compiled libcurl with mingw32-make mingw32-ssl-zlib I changed in all makefile.m32 pathes to the Zlib and OpenSSL files. All went fine, I recieved libcurl.a and libcurldll.a. I added into lib folder of my project libcurl.a and libeay32.a, libssleay32.a and libz.a. I built project - it says that everything is fine. I run - and it just terminated. I'm using MinGW and Eclipse. It is compiled with this: g++ -DCURL_STATICLIB -O0 -g3 -Wall -c -fmessage-length=0 -osrc\main.o ..\src\main.cpp g++ -L..\lib -oYTUploader.exe src\main.o -lcurl -lcurldll -lws2_32 -lwldap32 -leay32 -lssleay32 -lz I run DependencyWalker, and it says that it's missing ieshims.dll, libeay32.dll and ssleay32.dll. But WHY? Why it want OpenSSL dll, I'm using static linking! I built static libCurl library, with static libs of OpenSSL. About ieshims.dll I also can't get why it needs it! Help, please, I have no idea what is wrong! I compiled cUrl according to the instruction, everything should be fine.. --- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
