undefined reference to '_connect'

[RSeroka]

In plain cygwin, I can create a simple .c program to create a tcp client socket and connect to remote tcp socket. In crossbridge, this fails with a link error /tmp/ccqLouBl.o: error: undefined reference to '_connect'

I can't use inline AS3 to access a socket because I wish to use the socket in OpenSSL which requires a file descriptor.

Hi, The simpliest solution is to add an empty connect method in your program, like here: https://github.com/crossbridge-community/crossbridge-swc-openssl/blob/master/clientlib.c (line 98) The proper solution would be to implement Sockets using inline AS3.

OpenSSL code is translated into ActionScript ByteCode so you have to use AS3 API, because the SWF runs inside the Flash Player, so no native APIs are present.

Closing this one. It's not possible to use the socket in OpenSSL because everything is translated to actionscript/bytecode.
