My fault. I can't read the documentation. voikkoAnalyzeWordCstr returns a pointer to a null terminated list of analysis result. So in the code *v is null if there are no results.
This code causes a segmentation fault on Xubuntu 22.04 LTS
`#include
include <libvoikko/voikko.h>
int main() { const char *error;
VoikkoHandle *handle = voikkoInit (&error, "fi", "/usr/local/lib/voikko");
if (!handle) std::cout << "Pieleen meni." << std::endl;
std::cout << "Version " << voikkoGetVersion() << std::endl;
voikko_mor_analysis v = voikkoAnalyzeWordCstr (handle, "vappuasuidea"); const char a = voikko_mor_analysis_keys (*v);
for (size_t i = 0; a[i]; i++) { std::cout << a[i] << " " << voikko_mor_analysis_value_cstr (*v, a[i]) << std::endl; } return 0; }`
Compiling: g++ -g -Wall main.cc -o m -lvoikko
