如何在QMAKE中为头文件创建相对路径

Question

I am able to use the QMAKE_POST_LINK = copy address\\goes\\here.h and\\pastes\\here.h but want to take the original address as a relative path. I tried something like this…

HEADERS += -L”$$PWD/header.h” -header.h 

QMAKE_POST_LINK = copy -H”$$PWD\header.h” -header.h C:\really\long\address\goes\here\header.h;

this didn't work, so I tried something like this from a library relative path example I found earlier like so…

QMAKE_POST_LINK = copy -L”..\header.h” -header.h C:\really\long\address\goes\here\header.h;

Does anyone know how to copy a header file using a relative path approach? Or is it simply impossible?

Answer 1

Some time ago i implement a shared precompiled header, i used the following approach to copy a .pdb file to a other directory:

In .qmake.conf:

root_dir = $$PWD

In .pro File:

QMAKE_PRE_BUILD += xcopy /D /Y "$$root_dir\\src\\precompilemfc\\debug\\vc100.pdb" "$(ProjectDir)\\debug" &

Look here . PWD or _PRO_FILE_PWD_ are the correct way to do what you want.

In qt do not use "\\", use "\\\\" or better "/" instead.

This should work:

QMAKE_POST_LINK = copy "$$PWD\\header.h" C:\\really\\long\\address\\goes\\here;
