Hi
It is being worked on.

Actually the Installer framework I used was customised i.e. the source code of the QTIFW was modified to suit the need and then the required QTIFW binaries are rebuilt from the modified source.

Hi,
I'm having a similar problem with the auto installer for Linux 64. The installer gets about half way and then stops with the error message:

Error during installation process (qt.54.gcc_64):
File '/qt/5.4/gcc_64/bin/qmake' does not exist or is not an executable binary.

Checked the files and sure enough qmake is not executable by any user and only read write by root, I tried chmod but can't make the file executable. I don't really understand why its not working I have a working tool-chain and executing the run file as root.

I haven’t tried building it from source yet, just hoping some one might know what’s happening?
