How do you statically link a c library in go using cgo? Turns out my code is 100% fine; it was a copy of Go 1 0; under go 1 1 this works Under go 1 0, it doesn't (it's a bit lame answering my own question, I know; but the 'use -L -l answers below aren't right either; it had nothing to do with that)
cgo - How to specify the CFLAGS parameter in go build command line . . . from https: pkg go dev cmd cgo When building, the CGO_CFLAGS, CGO_CPPFLAGS, CGO_CXXFLAGS, CGO_FFLAGS and CGO_LDFLAGS environment variables are added to the flags derived from these directives Package-specific flags should be set using the directives, not the environment variables, so that builds work in unmodified environments
When using CGO_ENABLED is must and what happens The situation when cgo and CGO_ENABLED is absolute-must is when go compiler cannot produce the binary code for the target platform For instance, imagine I am writing a Space X control board embedded program in Go and I have to use C library and the compiler for the board
go - Why is CGO_ENABLED=1 default? - Stack Overflow CGO_ENABLED=1 uses the native OS (e g on Linux nsswitch) for ID lookup; CGO_ENABLED=0 uses a basic Go implementation (e g reads from etc passwd) - which does not include other ID registries the host may be aware of; Deployment While a CGO_ENABLED=1 binary may be smaller in size, it relies on delivering a host OS too Comparing Docker images:
Using a Windows DLL in Go with cgo - Stack Overflow You need to dlltool -dllname hunspell dll --def hunspell def --output-lib libhunspell a In gcc g++ does not using hunspell dll or hunspell lib as lib file @Fenistil You can syscall a dll file on Windows But with CGO it needs lib{name} a file
How to pass a Go pointer to Cgo? - Stack Overflow This will print the following: === Bypass Detection === A === Trigger Detection === panic: runtime error: cgo argument has Go pointer to Go pointer Using *C char bypassed the detection Only using unsafe Pointer will detect Go pointer to Go pointer scenarios
How do I use a cgo-based package on Windows? - Stack Overflow In order to use cgo on Windows, you'll also need to first install a gcc compiler (for instance, mingw-w64) and have gcc exe (etc ) in your PATH environment variable before compiling with cgo will work That being said, I still think you should consider sticking with the regexp package and try to make regular expressions as simple as possible
CGO; C function has int pointer argument, how to pass correct type? In order for the compiler to enforce the type safety, it requires you to do an explicit conversion or define the type at initialization In your example, you do: x := 0 This is the same as x := int(0) The int is implied Instead, you can do x := C int(0) However, I think the "cleaner" method would be to do what jnml recommended: var x C int
go - VSCode import C fails on modules - Stack Overflow internal lsp: use Go cgo source files instead of generated files Using CompiledGoFiles was causing metadata lookups to fail for cgo packages because it includes generated files in the Go build cache when the built-in 'go list' driver is used GoFiles includes both Go and cgo original file names, allowing metadata lookups to succeed
