Error compiling Wt on OSX Yosemite
Added by Freddy Martinez Garcia about 10 years ago
Hi guys...
I'm trying to compile Wt in OSX Yosemite because it's look like a great tool and I want to make some test, but I'm getting the following error:

Hey,
You need Wt 3.3.4rc2 for boost 1.57

Hi Koen... after compile the Wt version as you recomend me, the compilation end fine, but now..., I'm trying to run the HelloWord example and the compiler give a link error...
this is my link line in my .pro file, because I use Qt Creator as IDE:
LIBS +=-L/usr/local/lib -lwt -lwthttp -lwttest -lwtfcgi -lwtdbo
his is my link error:
Undefined symbols for architecture x86_64:
"Wt::WApplication::handleJavaScriptError(std::string const&)", referenced from:
vtable for HelloApplication in main.o
"Wt::WObject::setObjectName(std::string const&)", referenced from:
vtable for HelloApplication in main.o
"Wt::WApplication::makeAbsoluteUrl(std::string const&) const", referenced from:
vtable for HelloApplication in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [wt1] Error 1
14:57:38: The process "/usr/bin/make" exited with code 2.
Error while building/deploying project wt1 (kit: Desktop Qt 5.4.1 clang 64bit)

what I'm missing about the configuration ??
PD: Guys, great job with this framework... it's is amazing !!!!!

Hey,
It seems that you are mixing headers/libs of different versions: you are linking against a different set of wt libraries you already installed somewhere?
And you should only link against one of (-lwthttp -lwttest -lwtfcgi), probably -lwthttp, but that will not solve the above error.
