hi all
i’m trying to build a Qt webbrowser that compiles just in fedora 15,but refuses to build in haiku because of some sort of workaround in the code??(i think)
here is the error msg:
3rdparty/qtlocalpeer.cpp: In constructor 'QtLocalPeer::QtLocalPeer(QObject*, const QString&)': 3rdparty/qtlocalpeer.cpp:104:54: error: '::getuid' has not been declared make[1]: *** [../build/qtlocalpeer.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make[1]: Leaving directory `/boot/home/Desktop/nowrep-QupZilla-1c6bd7e/src' make: *** [sub-src-make_default] Error 2 ~/Desktop/nowrep-QupZilla-1c6bd7e>
it’s probably not too difficult to solve but i’m not a c++ guy,so i hope to find some help here.
and here is the .cpp file in question

I’m sure Haikuware would be happy to host and share it for you - have you tried submitting it to them yet?
