What I am trying to do is take a bunch of .C files that I created using f2c.exe on a Windows computer and use them in Xcode in an already existing project consisting primarily of Swift code.
On my Windows computer I used f2c to generate the .C files and then was able to build them to an executable and it runs as expected. So I took all of the .C files and brought them to my Xcode project and that is where I am currently stuck.
I only just added in the .C files and Xcode gives the following errors when I try to buid:
Undefined symbols for architecture arm64:
"_s_wsle", referenced from:
_xplannr_ in X1.o
...
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
X1.C is one of the .C files I have as an example. Additionally there are many repeated messages, I have just shown 1 for the purpose of this question. They all follow the same format as what I have provided here.
So what I am trying to understand is, what does the error message that is being provided indicating? Is this an issue of how the .C files were generated, or some configuration issue within Xcode that is not correct? Any ideas are appreciated.
