Hi,
I have a Qt project that uses an external library (linux).
The external lib is built statically from source each time using a shell script.
To include the lib in the project, I've created a .pri file that
defines libx like follows:
libx.name = libx
libx.target = $$PWD/libx_build/.libx.build
libx.commands = cd $$PWD/ && ./build_libx.sh
QMAKE_EXTRA_TARGETS += libx
PRE_TARGETDEPS += $$PWD/libx_build/.libx.build
So the logical way to build is:
- compile libx (can take some time)
- compile app
The sequential build I've managed to get right with the use of the
subdirs template.
But, this system only works when only using one compile job at a time.
Using for example make -j 4 will start the libx compilation as the
first job and already start compiling the app itself in parallel.
Resulting in undefined references because libx is not fully built yet.
So my question here: how can I make a qt project that compiles libx
before starting on the app itself, disregarding multiple jobs.
