Subject:	qmake-qt5 does not support QMAKE_POST_LINK on shared object targets
User-Agent:	Internet Messaging Program (IMP) H5 (6.0.4)
MIME-Version:	1.0
Note-from-DJ:	This may be spam

Dear qt5-base maintainers,

I noticed that QMAKE_POST_LINK is not applied to shared object targets  
in qmake (version 3.1 from Qt 5.9.4). The purpose of QMAKE_POST_LINK  
is to add custom script statements after the link step in  
qmake-generated Makefiles.

I checked cygwin's package files for qt5-base and found this patch  
which IMHO is lacking QMAKE_POST_LINK support.

The qmake.patch is taken from here:

https://cygwin.com/git-cygwin-packages/?p=git/cygwin-packages/qt5-base.git;a=blob;f=5.9-cygwin-qmake.patch;h=e6feef3d3a19e5e412adf6e4f2b9ac512553cdc1;hb=HEAD

I am referring to this part of the qmake.patch file:

   72              if (!isystem.isEmpty() && isSystemInclude(inc.toQString()))
   73 @@ -603,6 +603,14 @@ UnixMakefileGenerator::writeMakeParts(QT

# IMHO this part of the patch is missing to enable QMAKE_POST_LINK:
                   if(!project->isEmpty("QMAKE_POST_LINK"))
                       t << "\n\t" << var("QMAKE_POST_LINK");
                   t << endl << endl;

   85          } else if(project->isEmpty("QMAKE_HPUX_SHLIB")) {
   86              t << "\n\t";

Thanks for considering this bug report.

Best regards,

Matthias

Genauer um den Stacktrace.

Ich krieg' das schon hin, ich muß es ja normalerweise nur einmal durchturnen.

Probier's nochmal, irgendjemand scheint gerade den Sourceware-Server zu DOSen.


Mit freundlichen Grüßen.
