hello!
I am trying to compile/build a program which use the boost thread library.
I add the directoties(include,lib,link),the flag -mthreads but I still
have problem.Under CodeBlocks it's ok but not with cdt
the compiler output is the usuall:

g++ is missing the -c flag which forces it to build only the object file without linking. Thus, it tries and link to produce an executable file and cannot find the boost library which is missing because there is no linker option on the command line.
Well the basic problem is that the -c flag is missing
if you're using a managed make project go to the project properties, select c/c++ build, in the GCC G++ Compiler options, there's a "Miscellaneous" property page. Click on it and in the "other flag" line you should see "-c -fmessage-length=0" (without the quotes). If it's not there then add these options and it should build fine.
