WARNING: I don't know much about Windows so I might be doing everything wrong.
Trying to use the nightly DLL, I am getting Access Violation (and thus crash) upon opening a ZIM file.
Here's my reprocase.
#include <iostream>
#include <fstream>
#include <zim/archive.h>
using namespace std;
inline bool exists (const std::string name) {
ifstream f(name.c_str());
return f.good();
}
int main()
{
string filename = string("test.zim");
if (!exists(filename)) {
cout << "BAD filename" << filename << "..." << endl;
return 2;
} else {
cout << "About to open existing file: " << filename << "..." << endl;
}
zim::Archive zim = zim::Archive(filename);
cout << "Opened!" << endl;
return 0;
}
It requires any ZIM file named test.zim in cwd. I am using this one
here's how I build and run (I have Visual Studio Built Tools 2022 installed and used vcvars64.bat in the shell to target 64b build –zim-9.dll is 64b).
cl /EHsc /Iinclude repro.cpp /link libzim/zim.lib /out:rlz\tester.exe
cd rlz
tester.exe
echo Exit Code is %errorlevel%
cd ..libzim folder contains both zim.lib and zim-9.dll; include folder contains the zim subfolder. rlz folder contains the runtime stuff: icudt73.dll, icuin73.dll, icuuc73.dll, test.zim, tester.exe, zim-9.dll
Using WinDbg, I get some insights of what happens:
