I have a web application that uses the library
github.com/mattn/go-sqlite3
and I build using the command
env GOOS=darwin GOARCH=amd64 go build -ldflags "-s" $GOPATHsrc/github.com/user/example/main.go
I am building it in OSX El Capitan 10.11.5. When I run the executable on osx 10.8 and above it works correctly but fails on 10.7 and below with the error message "Illegal Instruction". If I remove the go-sqlite3 library it works correctly on 10.6 and 10.7.
Any help on what is going on here and how to fix this for 10.6 and 10.7?
I found this regarding sqlite3 using the -x option when compiling env CGO_CFLAGS="-mmacosx-version-min=10.6" GOOS=darwin GOARCH=amd64 go build -x -ldflags "-s" $GOPATHsrc/github.com/user/example/main.go:
