<TITLE>Gui/qt4 starts a bootstrap/configure during Make on Cygwin</TITLE>
</HEAD>
<BODY>
<!-- Converted from text/rtf format -->
<P><FONT FACE="Times New Roman">Scenario:</FONT>
<BR><FONT FACE="Times New Roman">I have a clean Cygwin compile environment, decide to do an SVN update to pull in current trunk.</FONT>
</P>
<P><FONT FACE="Times New Roman">When I update my main trunk, get a new configure.ac, it's time for a full configure/make cycle, no problem.</FONT>
<BR><FONT FACE="Times New Roman">I run the configure/make. This does all the tests, then generates all new makefiles, starts the full make of the trunk, going through all the modules.</FONT></P>
<P><FONT FACE="Times New Roman">There is, however, a difficulty down at the gui/qt4 level.</FONT>
<BR><FONT FACE="Times New Roman">For some reason, I do not know what it is, when this new configure/make reaches gui/qt4, gui/qt4/makefile is starting a new bootstrap/configure/make cycle:</FONT></P>
<P><FONT FACE="Times New Roman">make[5]: Leaving directory `/home/mfm/vlc-trunk/modules/gui/qnx'</FONT>
<BR><FONT FACE="Times New Roman">Making all in qt4</FONT>
<BR><FONT FACE="Times New Roman">make[5]: Entering directory `/home/mfm/vlc-trunk/modules/gui/qt4'</FONT>
<BR><FONT FACE="Times New Roman">cd ../../.. && /bin/sh ./bootstrap</FONT>
<BR><FONT FACE="Times New Roman">+ AUTOMAKESUCKS=no</FONT>
<BR><FONT FACE="Times New Roman">+ INSTALLSUCKS=no</FONT>
<BR><FONT FACE="Times New Roman">+ ACLOCAL_ARGS='-I m4'</FONT>
<BR><FONT FACE="Times New Roman">+ test -d extras/contrib/bin</FONT>
<BR><FONT FACE="Times New Roman">++ pwd</FONT>
<BR><FONT FACE="Times New Roman">+ export 'PATH=/home/mfm/vlc-trunk/extras/contrib/bin:/usr/local/bin:/usr/bin:/b</FONT>
<BR><FONT FACE="Times New Roman">in:/usr/X11R6/bin:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS:/cygdrive/c/W</FONT>
<BR><FONT FACE="Times New Roman">INDOWS/System32/Wbem:/cygdrive/c/Program Files/Microsoft SQL Server/80/Tools/Bin</FONT>
</P>
<P><FONT FACE="Times New Roman">What's happening is that the modules/gui/qt4 makefile has indeed launched a brand new round, a bootstrap/configure/make sequence. I think (could be wrong) that this occurs down at:</FONT></P>
<P><FONT FACE="Times New Roman">$(srcdir)/Makefile.am: $(srcdir)/Modules.am $(top_srcdir)/bootstrap</FONT>
<BR> <FONT FACE="Times New Roman">cd $(top_srcdir) && $(SHELL) ./bootstrap</FONT>
<BR><FONT FACE="Times New Roman">It generates a new makefile.am at the modules level, plus new makefile.am files for all subsidiary directories (modules/access, Modules/access_filter,…) You can see the config.log file at the root of the trunk updating as it runs all the configure checks.</FONT></P>
<P><FONT FACE="Times New Roman">The above uses two hours -- it takes about 30 minutes for the initial configure round, then about 90 minutes are spent on the make of the trunk before hitting modules/gui/qt4, which then goes back to square 1 and repeats the cycle.</FONT></P>
<P><FONT FACE="Times New Roman">Could someone knowledgeable take a look at the build script relative to gui/qt4, see if there's a way to get rid of this second round of generating makefile.am, running conf tests, etc. If there's something special about qt4 that requires a bootstrap whenever there's an update to the top-level configure.ac (even though the changes to it have nothing to do with qt4), great, no problem -- please just include that in the basic configure, don't let the build go all the way to gui/qt4 and then force a restart. </FONT></P>
<P><FONT FACE="Times New Roman">Thanks.</FONT>
