Considering using ArangoDB GO driver about arangodb-php-driver HOT 8 CLOSED

Looks like we have to create an own main package because of building the go driver leads to errors.

-buildmode=c-archive requires exactly one main package
-buildmode=c-shared requires exactly one main package

Here is an example blog post how to build c-shared.

@martin-schilling I've created a new branch golang which builds the c archive from go-velocypack. Now we have to find a way to call test() from the php-cpp main file. I guess there is some linker fun ;-)

We have to check what does this mean exactly

The only callable symbols will be those functions exported using a cgo //export comment

@martin-schilling I've added a test case. Now it's your turn. ;-) We have the following issues:

g++: warning: go/arangodb.a: linker input file unused because linking not done

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20160303/arangodb.so' - /usr/lib/php/20160303/arangodb.so:

@sandrokeil The linking stuff should hopefully be fixed now. I think the next aim should be getting some database interaction going in a test case.

@martin-schilling Thanks so much. I want to try the vpack example from the master branch first and maybe the go return value mapping. You can bring a new PR with the connection if you have time. 👍

There is an important issue

The correct program should use a type defined in C, rather than in Go, because otherwise the external C programs have to manually define a C struct matching the Go struct, which is non-trivial and error-prone.

We stick with C++.
