|

|

# We want to avoid that qtbase is built using cl.exe for example, and then for another repo

# gcc is picked up from %PATH%.
|
||
|
|
# The same goes when using a custom compiler on other platforms, such as ICC.
|
||
|
|
#
|
||
|
|
# There are a few exceptions though.
|
||
|
|
#
|
||
|
|
# When crosscompiling using Boot2Qt, the environment setup shell script sets up the CXX env var,
|
||
|
|
# which is used by CMake to determine the initial compiler that should be used.
|
||
|
|
# Unfortunately, the CXX env var contains not only the compiler name, but also a few required
|
||
|
|
# arch-specific compiler flags. This means that when building qtsvg, if the Qt created toolchain
|
||
|
|
# file sets the CMAKE_CXX_COMPILER variable, the CXX env var is ignored and thus the extra
|
||
|
|
# arch specific compiler flags are not picked up anymore, leading to a configuration failure.
|
||
|
|
#
|
||
|
|
# To avoid this issue, disable automatic embedding of the compilers into the qt toolchain when
|
||
|
|
# cross compiling. This is merely a heuristic, becacuse we don't have enough data to decide
|
||
|
|
# when to do it or not.
|
||
|
|
# For example on Linux one might want to allow mixing of clang and gcc (maybe).
|
||
|
|
#
|
||
|
|
# To allow such use cases when the default is wrong, one can provide a flag to explicitly opt-in
|

|
|
# or opt-out of the compiler embedding into the Qt toolchain.
|
||
|
|
#

# Passing -DQT_EMBED_TOOLCHAIN_COMPILER=ON will force embedding of the compilers.
