Unable to cross compile QT 5.5.1 for aarch64; aarch64-linux-gnu-ar fails with error
-
I get the below error when I cross compile QT on host centos and target aarch64
configure executed successfully.
config options:

/opt/gcc/aarch64-4.8.3.2014.04/bin/aarch64-linux-gnu-ar: invalid option -- Q
Note:
I have proper sys root. generated using cross-sysroot(python package)
cross compiler for aarch64 builds c++ code; picked from linaro.
building from sources. version: 5.5.1 -
Edit 1:
looks like the command is treating libQt5platformsupport.a as argument. when i renamed libQt5platformmsupport.a tp platformsupport.a. I pass the above error and end up withbelpw error:
/opt/gcc/aarch64-4.8.3.2014.04/bin/aarch64-linux-gnu-ar: two different operation options specified

Hi and welcome to devnet,
You seem to be mixing Debian's cross-compiler with something else.
What is exactly your setup ?

Thank you for taking time to respond.
Figured out the error. QT configure script is not auto populating the parameters required. I have provided -cr as arguments to AR command /opt/gcc/aarch64-4.8.3.2014.04/bin/aarch64-linux-gnu-ar..
/opt/gcc/aarch64-4.8.3.2014.04/bin/aarch64-linux-gnu-ar -cr
