I'm trying to integrate the Facebook SDK into my xcode project, and I've sort of hit a stumbling point.
After some research, I tried making sure I had the latest version of the FacebookSDK, as those who had the same errors as I were able to resolve their issues with the latest version, but that did not help, so I tried downloading the source code from github and using the build_all.sh command to recompile, which also did not help.
I'll have the full error log be at the end because it's super long, but here is the part at the end:
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I've seen plenty of strings related to this issue but as I stated previously, neither updating to the latest SDK (an unnecessary step in my case as I already had it) or recompiling the source code for armv7, armv7s fixed the issue.
Thanks in advance,
Tom
