Hello, i hope I get answers here, since this problem been bugging me since yesterday. I created a small code, using curl, I downloaded the library and put it in the mingw "lib" directory (libcurl.a and libcurldll.a), then I compiled my code with this option

gcc MyCode.c -DCURL_STATICLIB -lcurldll

(I used -lcurldll because I have errors on -lcurl) So now I have the application compiled. First it asked for libcurl.dll (I found it and feed it to the app) then it asked again for libshh2.dll (which I havn't found till now and having trouble compiling it).

When I look at some tutorial, these dll doesn't seem to be needed, what happens to mine?

What I have tried:

I tried compiling libshh2 from the source but no luck since yesterday

Solution 1

Your declaration of -DCURL_STATICLIB means you will use the static library, but you then try to link to the dll. If you use that declaration then you need to specify -lcurl not -lcurldll.

Thanks I really need this, but when I use -lcurl, I get an error

undefined reference to _imp_WSAStartup@08
undefined reference to _imp_WSACleanup@00
undefined reference to _imp_WSACleanup@00
*** libcurl.a(easy.o): bad reloc address in section ".data"
collect2.exe: error: id returned 1 exit status

But not in -lcurldll

You are missing the library (probably a socket library) that contains the referenced functions. Check the documentation for those functions to see which library you need.

You don't have to be an expert to read the documentation.
