hI
all:
I just installed QNX  and started to use it
one of my module got the follwoing error(in the same project with multiple moudles):(link error)

C:/QNX650/host/win32/x86/usr/bin/qcc -Vgcc_ntoarmv7 -Wl,--no-keep-memory  -lang-c++ -lang-c++    -oC:/Users/qiurosea/

C:/QNX650/target/qnx6/armle-v7/lib/crt1.o: In function `start_7':
(.text+0xe8): undefined reference to `main'

I checked this module, there is no main and also this module includes all the function definition.
to other modules in the same project, it is ok
though I used exact same configure.
I am stuck here for two days, I would need your help.
(I checked the ctrl.o, I do not have source code for this file)
thanks
