App build fails after some time (or number of builds)
asked 2019-05-21 19:05:06 +0300
I am learning to develop apps using SDK Qt Creator 4.8.1 (Sailfish SDK) on Ubuntu 19.04. Some first test-apps run well in the emulator and on my Xperia X. I learn by making small changes and frequently testing the results in the emulator. Now something weird has happened: after some time and various changes the build process faults with
/usr/lib/Scrt1.o: In function `_start':
(.text+0x28): undefined reference to `main'
collect2: error: ld returned 1 exit status
Even if I roll back all changes, the error remains. Only starting a new project and copying all the code as text, makes the build successful again. But after some time (or number of builds?) the error surfaces again.
Any suggestions how to overcome this problem?
Can you share your project?
