Disclaimer: I am not a programmer!
I am trying to compile scribus-0.7.2, a Page Layout program, built
against qt3. /usr/ports/print/scribus contains scribus-0.5, which
is the qt2 version.
On my Debian GNU/Linux, make works without a hitch. On my FreeBSD
stable box, I get a series of errors of the following type:
scribus.cpp:4217: assignment to `char *' from `const char *'
discards qualifiers
scribus.cpp: In method `int ScribusApp::DLLType(QString)':
scribus.cpp:4240: assignment to `char *' from `const char *'
discards qualifiers
*** Error code 1
Stop in /usr/local/scribus-0.7.2/scribus
These errors come from code similar to code that is given as an
example of how to handle exceptions in the Linux man page for
dlerror, /usr/compat/linux/man/man3/dlopen.3 Specifically, the
last error was produced by
int ScribusApp::DLLType(QString name)
{
void *mo;
char *error;
typedef int (*sdem0)();
sdem0 demo;
QString pfad = PREL;
pfad += "/share/scribus/plugins/" + name;
mo = dlopen(pfad, RTLD_LAZY);
if (!mo)
return 0;
dlerror();
demo = (sdem0)dlsym(mo, "Type");
if ((error = dlerror()) != NULL) <-- line 4240
{
dlclose(mo);
return 0;
}
int an = (*demo)();
dlclose(mo);
return an;
}
Both the FreeBSD and the Linux man pages list
const char *dlerror(void)
Why does c++ on FreeBSD produce an error on
error = dlerror()
and c++ on Debian Linux does not? What is the proper fix?
