Hello List,
I'm porting a c++ application to FreeBSD. I've got an error:
-----
~/work/src/FileChannel.cpp: In member function 'QString FileChannel::errorString()':
~/work/src/FileChannel.cpp:251: error: invalid conversion from 'int' to 'const char*'
~/work/src/FileChannel.cpp:251: error: initializing argument 2 of 'char* strcpy(char*, const char*)'
*** Error code 1
-----
A simle patch makes the application to be compiled without errors:

+++ src/FileChannel.cpp 2009-09-12 13:08:41.000000000 +0400

QString FileChannel::errorString()
{
- strcpy(lastErrorString, strerror_r(errno, lastErrorString, 0));
+ strcpy(lastErrorString, "XXX: Fix me: errno should be here");
return QString(trUtf8(lastErrorString));
}
-----
If I understand correctly, an integer value which is returned by
strerror_r() should be converted to const char*.
I have _very_ basic knowledge about c++. Hence my question.
Can someone provide a patch (a proof of concept)? Thanks!
