I tried googling the errors but couldn't find any that related to my issue. I installed cURL libraries okay but when I try to run this program: #include #include #include #include // callback function writes data to a std::ostream static size_t data_write(void* buf, size_t size, size_t nmemb, void* userp) { if(userp) { std::ostream& os = *static_cast(userp); std::streamsize len = size * nmemb; if(os.write(static_cast(buf), len)) return len; } return 0; } /** * timeout is in seconds **/ CURLcode curl_read(const std::string& url, std::ostream& os, long timeout = 30) { CURLcode code(CURLE_FAILED_INIT); CURL* curl = curl_easy_init(); if(curl) { if(CURLE_OK == (code = curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, &data_write)) && CURLE_OK == (code = curl_easy_setopt(curl, CURLOPT_NOPROGRESS, 1L)) && CURLE_OK == (code = curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L)) && CURLE_OK == (code = curl_easy_setopt(curl, CURLOPT_FILE, &os)) && CURLE_OK == (code = curl_easy_setopt(curl, CURLOPT_TIMEOUT, timeout)) && CURLE_OK == (code = curl_easy_setopt(curl, CURLOPT_URL, url.c_str()))) { code = curl_easy_perform(curl); } curl_easy_cleanup(curl); } return code; } int main() { curl_global_init(CURL_GLOBAL_ALL); std::ofstream ofs("output.html"); if(CURLE_OK == curl_read("http://google.com", ofs))

It produces a lot of cmath errors Since It would have taken a lot of space to put my code and error together: #include #include #include #include typedef unsigned char* pointer; void printDbPointers(void); void show_int(int); void show_bytes(unsigned char*, int); void floatingPointRep(); void fahrenheit(); int main() { int a = 100; show_int(a); floatingPointRep(); fahrenheit(); printDbPointers(); Sleep(100000); return 0; } void printDbPointers(){ char http://stackoverflow.com/questions/11367707/c-compile-time-cmath-error hi[7] = {'t', 'i', 'g', 'e', 'r', '\0'}; char *p, **dp; p = &(hi[0]); dp = &p; printf("%c %c\n", *p, **dp); printf("%p %p %p\n", p, *dp, hi); p+=1; printf("%c, %c\n", *p, **dp); printf("%p %p %p\n", p, *dp, hi); *dp+=2; printf("%c, %c\n", *p, **dp); printf("%p %p %p\n", p, *dp, hi); } void show_int(int x) { show_bytes((pointer) &x, sizeof(int)); } void show_bytes(pointer start, int len) { int i; for(i=0;iLanguages , .NET Framework > Visual C# Question 0 Sign in to vote I'm trying to compile the following code using visual c++ express edition that I downloaded for free.

I just listed some of them. I did exactly http://www.ogre3d.org/forums/viewtopic.php?f=2&t=71281 what they said for creating a project and c file.
