Unsolved Qt 5.6 & mingw_49_32

[Jedd]

I recently updated to Qt 5.6 (compiled static) and mingw49_32. As a result,
when I compile, my program now refuses to run, complaining:

libgcc_s_dw2-1.dll
libwinpthread-1.dll
libstdc++-6.dll

are missing. I can include these DLLs with the program and all works,
however, previously with Qt 5.4.2/mingw491_32 my programs were fully
static, no external DLLs required.

I'd rather not ship these DLLs. How can I tell mingw to compile them into the program statiically?

Hi! Can you try adding "-static-libgcc -static-libstdc++" to your compiler flags?

Apologies to Diamond Platypus, I must not have had this post flagged as watch.

Anyway, I did add:

QMAKE_CXXFLAGS += -static-libgcc -static-libstdc++

To my .pro file

I still have missing dlls:

libgcc_s_dw2-1.dll
libwinpthread-1.dll
libstdc++-6.dll
