I replaced #define with bool as suggested (note: why this doesn't work?)
if (system("which kchmviewer > /dev/null") == 0)
{
// "which kchmviewer" exit code 0
bool useKchmviewer = true;
}
else
{
// "which kchmviewer" exit code 1
bool useKchmviewer = false;
}
but the compilation was terminated with the following message (screenshot):
warning: unused variable ‘useKchmviewer’ [-Wunused-variable]
Based on what I read on the Internet (I need to declare a variable first,
then I can change the value later), I tried a different approach (note: while
this seems to work, I would also like to know how to do this, if possible,
using an if…else statement as pointed out above):
bool useKchmviewer = false;
if (system("which kchmviewer > /dev/null") == 0)
{
// "which kchmviewer" exit code 0
useKchmviewer = true;
}
This worked, however once I tried to use this with
if (!useKchmviewer)
{
const QString name = "UserManual";
const QString suffix = "pdf";
}
else
{
const QString name = "VirtualBox";
const QString suffix = "chm";
}
the compiler was unhappy again (screenshot). Based on the answer from Stack
Overflow, I altered this code too (note: why is this necessary?):
QString name = "UserManual";
QString suffix = "pdf";
if (useKchmviewer)
{
name = "VirtualBox";
suffix = "chm";
}
After this, the compilation finished successfully and the changes worked as
expected. However, I still need to adapt other parts of the code so this is
only a partial success.
P.S.: I understand how frustrating can be to help a person that doesn't have
any knowledge in the topic he/she's expecting to get help in, but please bear
with me.
