I have built FBReader 0.8.17 for iLiad.
It works in Scratchbox enviroment but fialed on iLiad.
I added some notification into its source code and found where it failed. But I can't figure why.

This is the main entrance in "main.cpp"

int main(int argc, char **argv) {
	printf("1\n");//my personal addon
	if (!ZLibrary::init(argc, argv)) {
		printf("!ZLibrary::init\n");
		return 1;
	}
	printf("2\n");//my personal addon
	ZLibrary::run(new FBReader(argc == 1 ? std::string() : argv[1]));
	printf("3\n");//my personal addon
	ZLibrary::shutdown();
	return 0;
}

"ZLibrary.cpp" called by "main.cpp"

bool ZLibrary::init(int &argc, char **&argv) {
#ifdef ZLSHARED
	const std::string pluginPath = std::string(LIBDIR) + "/zlibrary/ui";

	void *handle = 0;
	printf("11\n");//my personal addon
	fflush(stdout);
	if ((argc > 2) && std::string("-zlui") == argv[1]) {
		handle = dlopen((pluginPath + "/zlui-" + argv[2] + ".so").c_str(), RTLD_NOW);
		argc -= 2;
		argv += 2;
	}
	printf("12\n");//my personal addon
	fflush(stdout);
	if (handle == 0) {
		DIR *dir = opendir(pluginPath.c_str());
		if (dir == 0) {
			return false;
		}
		std::vector<std::string> names;
		const dirent *file;
		struct stat fileInfo;
		while ((file = readdir(dir)) != 0) {
			const std::string shortName = file->d_name;
			if ((shortName.substr(0, 5) != "zlui-") ||
					!ZLStringUtil::stringEndsWith(shortName, ".so")) {
				continue;
			}
			const std::string fullName = pluginPath + "/" + shortName;
			stat(fullName.c_str(), &fileInfo);
			if (!S_ISREG(fileInfo.st_mode)) {
				continue;
			}
			names.push_back(fullName);
		}
		closedir(dir);
	printf("13\n");//my personal addon
fflush(stdout);
		std::sort(names.begin(), names.end());
		for (std::vector<std::string>::const_iterator it = names.begin();
				 (it != names.end()) && (handle == 0); ++it) {
			handle = dlopen(it->c_str(), RTLD_NOW);
		}

		if (handle == 0) {
			return false;
		}
	}
	dlerror();
	printf("14\n");//my personal addon
fflush(stdout);
	void (*initLibrary)();
	*(void**)&initLibrary = dlsym(handle, "initLibrary");
	if (dlerror() != 0) {
		return false;
	}
#endif /* ZLSHARED */
	printf("15\n");
fflush(stdout);
	initLibrary();
	printf("16\n");//my personal addon
fflush(stdout);
	if (ZLibraryImplementation::Instance == 0) {
		return false;
	}
	printf("17\n");//my personal addon
fflush(stdout);
	ZLibraryImplementation::Instance->init(argc, argv);
	return true;
}

When I execute FBReader in mrxvt on iLiad, I got output:

1
!ZLibrary::init

Then FBReader stopped. And ZLibrary::init didn't output anything. (The reasone that ZLibrary::init() didn't output anything was caused by my forgetting to update lib file. ZLibrary::init() did executed to printf("13\n") and returned false.)
