LINK : fatal error LNK1181: cannot open input file 'qtmain.lib'

[Nan Feng]

Dear community folks, I'm having some issues. When using Qt 4.8.7 after static compilation. An error occurred: LINK : fatal error LNK1181: cannot open input file "f:\Environment\MSVC-2005-QtStaticLib\lib\QtCore.lib"
This directory is the directory where I compiled the source code. Obviously, the compiler is looking for the lib file in this directory. Libraries=../lib is configured in qt.conf in the same directory of qmake.exe, and an error occurs when compiling again: LINK : fatal error LNK1181: The input file "qtmain.lib" cannot be opened. QtCore.lib and qtmain.lib are in the same level directory. Why does this happen? How to configure qt.conf so that the location of the compiler can be moved arbitrarily? Or how to configure it at compile time?

In addition, I would like to ask, does Qt 5.6.3 support Windows XP Home Edition after recompilation? Deploy only.

does Qt 5.6.3 support Windows XP Home Edition after recompilation?

https://doc.qt.io/archives/qt-5.6/supported-platforms.html

Did you also do "make install" after building Qt?

During compilation you specify where Qt should be located in the end. This path is hard-coded into qmake and qmake will always look in that directory for everything Qt-related. It is not easily possible to change directories later on.

@jsulm Hi. I am very glad that you took your precious time to reply to me. Yes, I did nmake install. I saw the link you gave. It is sufficient to deploy Qt 5.6.3 on Windows XP only. So does this Windows XP refer to all editions? For example: Home Edition (2001 version), or Pro version. SP3. All possible?

All possible?

All, edition doesn't matter (except embedded versions maybe).

@SimonSchroeder Hi nice to meet you. thank you for your reply. Since this information is written dead in qmake. So how does Qt official 4.8.7 achieve any installation location?

[Nan Feng]

@jsulm OK, there are two more questions.

1. About the qmake program contains a lot of information when compiling. As a result, it cannot be moved at will, so why can Qt officially set the installation location at will?
2. Will the Qt 5.15.3 binary distribution and source code be available to open source users in a few days? Because it's almost a year since his release date. Qt officially promises to distribute to non-commercial users for one year.

Installation location can be set by you, either using online/offline installer or when compiling Qt by yourself. Qt only defines default locations if you do not tell it where to install.

Qt 5.15.3 will not be available as oss (not as binary at least).

[Nan Feng]

@jsulm So is it possible to get the source code for 5.15.3?

@jsulm OK, thanks. There's another question I just forgot to mention. For example button: QSS After setting border-left, the text will be offset to the right. And as the border-width increases, the text offset also increases. Is there any way to keep him from drifting?
