Compile problem with gcc-4.7 on i686 => Fixed in SVN

[Marius Cirsta]

I'm having the following problem when compiling Vbox on Linux i686:

/var/tmp/fst/src/VirtualBox-4.1.14/src/VBox/Runtime/generic/critsect-generic.cpp: In function 'int RTCritSectEnterMultipleDebug(size_t, RTCRITSECT, RTUINTPTR, const char*, unsigned int, const char*)': /var/tmp/fst/src/VirtualBox-4.1.14/src/VBox/Runtime/generic/critsect-generic.cpp:459:73: error: narrowing conversion of 'uId' from 'RTUINTPTR {aka long long unsigned int}' to 'volatile RTHCUINTPTR {aka volatile unsigned int}' inside { } is ill-formed in C++11 [-Werror=narrowing] cc1plus: all warnings being treated as errors

Vbox was being compiled with these options:

./configure --disable-docs --nofatal --disable-pulse

Everything compile fine on AMD64.

Thanks for the report. Actually the error is only triggered when using gcc-4.7. The following fix (which will be included in the next maintenance release) fixes the problem:

Fix is part of VirtualBox 4.1.16.
