I am not an expert in GLIB, but, following your suggestion, I have added
the following variables. Notice that it is similar to the one in your
example.
--------
gchar strMsg;
strMsg = g_strdup("Under Comstruction ... ");
--------
However, this statement gives me an error that reads:
main.cpp: In function `int main(int, char**)':
main.cpp:25: error: invalid conversion from `gchar*' to `gchar'
main.cpp:83: error: invalid conversion from `gchar' to `void*'
main.cpp:83: error: initializing argument 1 of `void g_free(void*)'
make.exe: *** [main.o] Error 1
Execution terminated
-------------
What am I doing wrong?
TIA
