Qt 5.12 and static build.

EndrII 0

I have simple console application with qt core,
I used to build a project with qt 5.11 and everything was fine, but when it was over 5.12, the following problem appeared:

I build qt as follows:

./configure -confirm-license -prefix $BASE_DIR/$QT_DIR -release -optimize-size -static -no-opengl -no-openssl -opensource -nomake tests -nomake examples -no-gui -no-widgets -no-dbus -no-accessibility

qt is successfully built, but when I build my application with the static flag, it starts to require dynamic libraries (although this should not be, and everything was fine with qt 5.11) and is not going to happen because of this.

export PATH=$PATH:$BASE_DIR/$QT_DIR
$BASE_DIR/$QT_DIR/bin/qmake -r QMAKE_LFLAGS+="-static -static-libgcc -static-libstdc++" $BASE_DIR/CQtDeployer.pro

Here is the build error:

g++ -static -static-libgcc -static-libstdc++ -Wl,-O1 -Wl,--gc-sections -o build/release/cqtdeployer main.o   -L/media/D/own/Console-QtDeployer/QuasarAppLib/build/release -lQuasarApp -L/media/D/own/Console-QtDeployer/Deploy/build/release -lDeploy -L/media/D/own/Console-QtDeployer/pe/pe-parser-library/build/release -lpe-parser-library -L/media/D/own/Console-QtDeployer/staticQt/lib -lQt5Core -lm /usr/lib/x86_64-linux-gnu/libz.so /usr/lib/x86_64-linux-gnu/libpcre2-16.so /usr/lib/x86_64-linux-gnu/libdl.so /usr/lib/x86_64-linux-gnu/libgthread-2.0.so /usr/lib/x86_64-linux-gnu/libglib-2.0.so -lpthread

Use built-in libz when building Qt:

-zlib ................ Select used zlib [system/qt]

Thanks, it helped me, but now it requires a different library, is it possible to customize qt in some way so that by default it will always choose its own library build, if possible?

now :

/usr/bin/ld: attempted static link of dynamic object `/usr/lib/x86_64-linux-gnu/libpcre2-16.so'

No, each external lib has to be configured separately. See output of configure --help.

Still such question why at static assembly dynamic still can be required?

g++ -static -Wl,-O1 -Wl,--gc-sections -o build/release/cqtdeployer main.o   -L/media/D/own/Console-QtDeployer/QuasarAppLib/build/release -lQuasarApp -L/media/D/own/Console-QtDeployer/Deploy/build/release -lDeploy -L/media/D/own/Console-QtDeployer/pe/pe-parser-library/build/release -lpe-parser-library -L/media/D/own/Console-QtDeployer/staticQt/lib -lQt5Core -lm /media/D/own/Console-QtDeployer/staticQt/lib/libqtpcre2.a /usr/lib/x86_64-linux-gnu/libdl.so /usr/lib/x86_64-linux-gnu/libgthread-2.0.so /usr/lib/x86_64-linux-gnu/libglib-2.0.so -lpthread

No idea. Perhaps you should pass -static-libgcc -static-libstdc++ to Qt compilation as well. Because your code will use static runtime, but Qt still expects dynamic one.

did not help (
I reopen this issue.

This is more like a qmake bug.
The fact is that I changed the list of libraries necessary for linking in my makefile to

LIBS          = $(SUBLIBS) -L/media/D/own/Console-QtDeployer/QuasarAppLib/build/release -lQuasarApp -L/media/D/own/Console-QtDeployer/Deploy/build/release -lDeploy -L/media/D/own/Console-QtDeployer/pe/pe-parser-library/build/release -lpe-parser-library -L/media/D/own/Console-QtDeployer/staticQt/lib -lQt5Core -lm /media/D/own/Console-QtDeployer/staticQt/lib/libqtpcre2.a -ldl -lglib-2.0 -lpthread

and it all worked, I got the right binary.

maybe you need to configure qmake in some special way?
