Hi folks, I have: installed eclipse on ubuntu 10.10 installed libbost 1.4 using sinaptic pkg manager started a simple new c++ project, #include int main(int argc, char* arg[]){ } I tried to build it, and had the error:

blablabla...so on... a lot more errors. what am I missing here? I dont understand the error message, and tried to write -pthread wherever I could, but did not work.

Did you get the same error?

Any tips? detailed or stepbystep solution please, because I am a beginner, and dont understand chinese:) thank you guys

Did you try g++ -pthread -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" -MT"main.d" -o"main.o" "../main.cpp" In Christ, Steven Watanabe
