[SOLVED]Anyone using synapse httpsend on Linux 64bit and working? lazarus / 38-Networking and Web Programming ---------------------------------------------------------------------- snorkel · 2014-03-05 20:04 I have a app  I wrote on win32 that uploads a file using httpsend from they synapse library using HTTPS, this works perfect on win32. When I compile it on linux 64bit it simply does not upload the file, no error, it just returns a empty result from the server. I don't know if it works ok on Linux 32 bit, but I imagine it does. When I was looking at the compiler directives using Laz 1.2 which shows which ones are active, The OS2 ones are showing active, so I am thinking this is a issue with Synapse not knowing it's 64bit or something. ---------------------------------------------------------------------- eric · 2014-03-05 22:56 I'm using HTTPSend on Linux 64bit, but only to download files, not upload. There are no apparent issues. ---------------------------------------------------------------------- snorkel · 2014-03-06 01:05 with HTTPS ?   I think it might be related to openSSL. ---------------------------------------------------------------------- eric · 2014-03-06 07:30 No, just plain HTTP. I'm using this method: http://wiki.freepascal.org/Synapse#Advanced_version ---------------------------------------------------------------------- Leledumbo · 2014-03-06 16:06 Why don't you test on a local server that you create yourself? ---------------------------------------------------------------------- snorkel · 2014-03-06 17:05 Got it working. I thought I had all the SSL stuff installed, but apparently synapse needs libssl.so So I had to do: sudo apt-get install libssl1.0.0 libssl-dev Works now.
