I have a project in VC++ where I am using libcurl library. Even after adding the library in Additional Dependencies I am facing around 150 unresolved external errors, all majorly for libcurl_a.lib file.

Error -

1>libcurl_a.lib(mime.obj): error LNK2019: unresolved external symbol imp__feof referenced

    Perhaps you are not properly linking libcurl. Perhaps you are using the wrong compiled binary for your compiler or mixing 32 and 64 bit. Maybe you put the wrong path in the linker dependency. – drescherjm Nov 15 '21 at 15:19

    You will have to show some of the build output for a chance of help. I recommend copying at least some of the errors from the top of the Output tab (yes the Output tab and not the errors list) to the question. The output tab is in proper order and in a better text format. – drescherjm Nov 15 '21 at 15:24

    Is this the problem: [https://stackoverflow.com/questions/46585662/windows-linking-to-libcurl-a-lib](https://stackoverflow.com/questions/46585662/windows-linking-to-libcurl-a-lib) – drescherjm Nov 15 '21 at 15:25
  • Hey, Thanks for looking into it, I have added some part of errors from Output tab. I have given the libcurl_a.lib path in the Linker->Input->Additional Dependency section – Anjali Singh Nov 15 '21 at 15:45
  • Did you add all the required library files and include header files?

I have solved this problem by building the library with RTLIBCFG=static option.
