building Qt for Windows (revisited)

[mzimmers]

Hi all -

Last year, I thought I had this issue resolved (see this thread for details), but evidently some changes have occurred and I need to update my procedure.

This was the configure command I used:

configure -static -static-runtime -developer-build -opensource -release -platform win32-g++ -opengl desktop -nomake tests -recheck-all

Here's the error I'm getting now when I try to run mingw32-make:

Any ideas where I went wrong? Thanks.

As an aside, I believe that the wiki on this subject, which was already flawed, is now broken. The PS script it references relies on the old method of obtaining source code, which I'm fairly sure won't work any more. Once I get my build process working, I'll publish the complete steps here.

[mzimmers]

BTT. I need to get this working again; any suggestions?

Thanks...

[kshegunov]

Do you really need the examples built? If not, try adding -nomake examples.

EDIT:
Why are you using -developer-build? Are you going to be patching Qt? If not then remove it, and it's incompatible with -release.

[mzimmers]

@kshegunov I fixed the configure command per your suggestions. Now make fails here:

Am I missing a pathname to point to QtCore? Thanks.

PS: I got some of my configure options from here if you're interested.

Not that I know of.

I got some of my configure options from here if you're interested.

What are is the exact line you used? (and please include it on every iteration, to make keeping track easier)
How did you obtain the source and which Qt version is this?

[mzimmers]

My latest configure command is:

configure -mp -confirm-license -static -static-runtime -opensource -release -platform win32-g++ -opengl desktop -nomake examples -nomake tests -nomake tools -recheck-all

My make command is:

mingw32-make -k -j4

Which is in C:\Qt\Tools\mingw730_32\bin.

I got the source from github, using branch 5.12.6.

Thanks...

@mzimmers said in building Qt for Windows (revisited):

My latest configure command is

I don't know what -mp does, but everything else seems okay. I'd add -redo to make sure it recompiles qmake so there's no doubt you're working from a clean start.

My make command is

What does -k mean?

I got the source from github, using branch 5.12.6.

Okay, I usually clone from code.qt.io, but the github mirror should be working fine as well.

Sorry couldn't be of more help, but it doesn't seem you're doing something wrong. If -redo doesn't help, perhaps (re)start from a clean tree?

[mzimmers]

-mp is multi-processing (akin to the -j option for make).
-k, --keep-going Keep going when some targets can't be made.

I'll start again with the "-redo" and see what happens. Failing that, I'll kill the copy I have and get another, from code.qt.io. I'll report back with my findings.

Thanks for looking.

[mzimmers]

Current steps attempted:

1. git clone from the Qt (not github) repository (5.12 branch)
2. add the following (through a script):

SET _ROOT=C:\qt5
SET PATH=C:\Qt\Tools\mingw730_32\bin;%PATH%
SET PATH=%_ROOT%\qtbase\bin;%_ROOT%\gnuwin32\bin;%PATH%

3. configure as follows:

configure -mp -confirm-license -static -static-runtime -opensource -release -platform win32-g++ -opengl desktop -nomake examples -nomake tests -nomake tools -recheck-all -prefix /Qt5Static

4. mingw32-make -j4

I get this error:

g++ -c -include .pch/release/qt_pch.h -fno-keep-inline-dllexport -msse2 -mstackrealign -mfpmath=sse -O3 -std=c++1z -ffunction-sections -fdata-sections -fexceptions -mthreads -Wall -W -Wextra -Wvla -Wdate-time -Wshift-overflow=2 -Wduplicated-cond -Wno-stringop-overflow -DUNICODE -D_UNICODE -DWIN32 -DMINGW_HAS_SECURE_API=1 -DWINVER=0x0601 -D_WIN32_WINNT=0x0601 -DQT_NO_USING_NAMESPACE -DQT_NO_FOREACH -DQFLOAT16_INCLUDE_FAST -DQT_NO_NARROWING_CONVERSIONS_IN_CONNECT -DQT_BUILD_CORE_LIB -DQT_BUILDING_QT -D_CRT_SECURE_NO_WARNINGS -D_USE_MATH_DEFINES -DQT_ASCII_CAST_WARNINGS -DQT_MOC_COMPAT -DQT_USE_QSTRINGBUILDER -DQT_DEPRECATED_WARNINGS -DQT_DISABLE_DEPRECATED_BEFORE=0x040800 -DQT_NO_DEBUG -DPCRE2_CODE_UNIT_WIDTH=16 -DPCRE2_STATIC -I. -Iglobal -I../3rdparty/harfbuzz/src -I../3rdparty/md5 -I../3rdparty/md4 -I../3rdparty/sha3 -I../3rdparty -I../3rdparty/double-conversion/include -I../3rdparty/double-conversion/include/double-conversion -I../3rdparty/tinycbor/src -I../../include -I../../include/QtCore -I../../include/QtCore/5.12.7 -I../../include/QtCore/5.12.7/QtCore -Itmp -I.moc/release -I.tracegen/release -I../3rdparty/pcre2/src -I../../mkspecs/win32-g++  -o .obj/release/qcollator.o tools/qcollator.cpp

EDIT: I also tried without the -nomake tools (purely as a guess); same results.

[kshegunov]

I'm out of ideas. My best guess now is to disable the pch (i.e. -no-pch), and I'd suggest removing -mp just to be sure it's not interfering.

PS.
Can you try building dynamic binaries, just to compare?

[mzimmers]

@kshegunov tried "-no-pch" and removing "-static -static-runtime" and got the same errors.

I did find windows-requirements, which is interesting, but I never had to manually add any of those things in the past. Do I really need to do that now?

I don't know, sorry. Nothing else comes to mind. :|

I don't think so. I haven't done so the last time I build Qt on windows a couple of months or so ago.

[mzimmers]

I'm going to try 5.13; I can't think of anything else either.

[mzimmers]

Update on this: it turns out that there were some artifacts from a prior version of Qt that caused make to look at/use incorrect locations for some files. I blew away the directory and re-cloned.

Here are my condensed notes on how to accomplish this (note that this is for a static build):

1. $ git clone https://code.qt.io/qt/qt5.git
2. $ cd qt5
3. $ git checkout v5.14.1 // or whatever
4. $ perl init-repository

	or 
	
   $ git submodule update --init --recursive
5. $ configure -confirm-license -static -static-runtime -opensource -release -platform win32-g++ -opengl desktop -nomake examples -nomake tests -nomake tools -recheck-all -prefix c:\qt5\5.14.1\static
6. mingw32-make -j4
7. mingw32-make install // if a prefix option was specified in configure

Thanks to everyone for the help on a frustrating issue.
