Issues Building Static Qt

mzimmers

Hi all -

Updated Qt, and ran into problems building a static version.

I tried following the directions here and this is what I got:

C:\Qt\Static\src\qt-everywhere-src-5.12.3>configure -static -release -no-exceptions
+ cd qtbase
+ C:\Qt\Static\src\qt-everywhere-src-5.12.3\qtbase\configure.bat -top-level -static -release -no-exceptions
Cannot detect host toolchain. Please use -platform. Aborting.

C:\Qt\Static\src\qt-everywhere-src-5.12.3>configure -static -release -no-exceptions -platform win32-g++
+ cd qtbase
+ C:\Qt\Static\src\qt-everywhere-src-5.12.3\qtbase\configure.bat -top-level -static -release -no-exceptions -platform win32-g++
Bootstrapping qmake ...
'mingw32-make' is not recognized as an internal or external command,
operable program or batch file.

I remember running into issues building a static Qt library in the past, but not this particular error. Can someone tell me where I went wrong?

Thanks...

Hi
For your second try
C:\Qt\Static\src\qt-everywhere-src-5.12.3>configure -static -release -no-exceptions -platform win32-g++

try running
"C:\Qt\5.12.3\XXXX\bin\qtenv2.bat" FIRST
Its in your compiler folder. I dont have mingw installed so dont know the excact path.
It will set up paths etc. as it seems it cannot find
mingw32-make

Hi mrjj -

That worked, though I had to remove the "-no-exceptions" command line option.

Unfortunately, I also got this warning:

WARNING: Using OpenGL ES 2.0 on Windows without ANGLE.
The build will most likely fail.
Specify -opengl desktop to use regular OpenGL.

This I have seen in the past, but I don't remember what I did about it. Might you be familiar with this issue?

I went ahead and ran mingw32-make, but got this error:

g++ -static -static-libgcc -Wl,-s -Wl,-subsystem,console -Wl,--gc-sections -o ..\..\..\bin\moc.exe .obj/release/moc.o .obj/release/preprocessor.o .obj/release/generator.o .obj/release/parser.o .obj/release/token.o .obj/release/main.o  -LC:\Qt\Static\src\qt-everywhere-src-5.12.3\qtbase\lib C:\Qt\Static\src\qt-everywhere-src-5.12.3\qtbase\lib\libQt5Bootstrap.a -luser32 -lole32 -ladvapi32 -lshell32 -lnetapi32 -luuid C:\Qt\Tools\mingw730_64\x86_64-w64-mingw32\lib\libz.a .obj\release\moc_resource_res.o

.obj\release\moc_resource_res.o: file not recognized: File format not recognized

Any ideas on this one?

mrjj

Hi
Nope, i only build a static version once a long time ago :)
Well did you add the -opengl desktop ?

file not recognized: File format not recognized

that's very odd.
Did you start clean over so nothing was left from the previous run?

mzimmers

Yes, I added the -opengl desktop and then got this error:

ERROR: Feature 'opengl-desktop' was enabled, but the pre-condition '(config.win32 && !config.winrt && !features.opengles2 && (config.msvc || libs.opengl))
                          || (!config.watchos && !config.win32 && !config.wasm && libs.opengl)' failed.

ERROR: The OpenGL functionality tests failed!
You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

I have no idea what to do about this.

EDIT:

No, I didn't run a clean command. Are you referring to a make clean, or to something to undo the configure command?

mrjj

@mzimmers
yes something like clean as to be sure it start fresh over.
Hmm its odd that !config.win32 failed as you did specify that.

mzimmers

I need to return my attention to this issue. The problem at hand is this error when I run configure:

WARNING: Using OpenGL ES 2.0 on Windows without ANGLE.
The build will most likely fail.
Specify -opengl desktop to use regular OpenGL.

I I have my environment variable ANGLE_DIR set to C:\Qt\Static\src\qt-everywhere-opensource-src-5.12.3\qtbase\src\angle. assume that configure is looking for ANGLE source, correct? Or, do I need to build ANGLE libraries before invoking the configure command?

Thanks...

mzimmers

BTT.

Can anyone please give me some guidance? I'm in need of static builds.

jsulm

@mzimmers Take a look at https://wiki.qt.io/Building_a_static_Qt_for_Windows_using_MinGW

mzimmers

@jsulm thanks. The PS script that page references is a bit out of date, so I made some changes to it, but it doesn't address the OpenGL error I'm getting on the configure step.

mzimmers

Anyone have any ideas on this? Should I report this as a bug?

kshegunov

Does it fail if you ignore the warning? I don't recall doing anything special when building Qt on windows (dynamic, but still).

mzimmers

@kshegunov yes it does fail. I get the impression there's some implicit set-up to be done for the Angle stuff, but it's not documented anywhere that I can find.

mzimmers

Here's an error message I'm getting during configure:

C:\Qt\Static\src\qt-everywhere-src-5.12.3> configure -prefix C:\Qt\Static\src\qt-everywhere-src-5.12.3\qt-build -static -static-runtime -opengl desktop -nomake examples -nomake tests
...
Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
On macOS, you can use Homebrew's llvm package.
On Windows, you must set LLVM_INSTALL_DIR to the installation path.

ERROR: Feature 'opengl-desktop' was enabled, but the pre-condition '(config.win32 && !config.winrt && !features.opengles2 && (config.msvc || libs.opengl))
                          || (!config.watchos && !config.win32 && !config.wasm && libs.opengl)' failed.

QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

Check config.log for details.

So, I gather that I'm missing something related to OpenGL, but I really don't know what it might be.

kshegunov

Do you have the opengl dev headers (I think they're in the directx sdk)?

mzimmers

I didn't have DirectX installed. Now that I do, though, I don't see anything that looks like what you're talking about. None of the files listed here are in the DirectX directory.

I'm completely out of my element here -- do I need an Angle installation as well?

kshegunov

@mzimmers said in Issues Building Static Qt:

Did you by mistake install the redistributables? I was talking specifically about the SDK (software development kit). If I'm not mistaken it [the DX SDK] is also available through the Windows SDK.

I'm completely out of my element here -- do I need an Angle installation as well?

Honestly me too a bit. I think you don't, although I'm not completely certain. If I recall correctly Angle is a software implementation to substitute the GL. I hope someone's going to correct me if I'm wrong.

mzimmers

No, I installed the SDK -- went into this directory: C:\Program Files (x86)\Microsoft DirectX SDK (June 2010).

I did open a bug report for this (here) though I'm not sure that the assignee fully understands what's going on. I'm just amazed that more people aren't experiencing something similar.

mzimmers

UPDATE:

I got the configure (and make/make install) to run successfully. On a suggestion from the person handling the bug case I opened, I deleted my existing source base and re-extracted it. I then created a subdirectory for the build, went into that subdirectory and issued this command:

..\configure -prefix C:\QtStatic\qt-everywhere-src-5.12.3 -platform win32-g++ -static -static-runtime -opengl desktop -nomake examples -nomake tests -recheck-all

Then ran mingw32-make.

Both the wiki page on this topic, and the powershell script it references, are flawed. And the build process is a bit fragile: even by creating and using a shadow build, I somehow corrupted my source, causing the OpenGL red herring that was driving me crazy. A fresh extraction was the key, but a couple other points:

do use the -platform switch when running configure
-static and -static-runtime are both needed
when in doubt, use the -recheck-all switch

Anyway, this hopefully closes out this nasty little chapter. Thanks to all involved; I'll be back eventually with some follow-up questions on creating standalone apps.
