"not a dynamic executable"

[lexesv]

Hello Do you plan to add the possibility of building a portable application? --ldflags '-extldflags "-static"'

[deuill]

I've added provisional support for building against a static PHP 7.x library, but am still fixing some issues with receiver bindings. The plan is to build a binary distribution of go-php that doesn't require building or downloading the PHP library.

Thank you, but

Please, could you describe process of building a static application?

Debian 8

1. aptitude install libphp7.0-embed php7.0-dev
2. go get github.com/deuill/go-php
3. write a test application.
4. if go build - ldd not return "not a dynamic executable" if go build --ldflags '-extldflags "-static"' - return error

And another question, you do not make it possible use a custom php.ini?

[deuill]

If you're building against Debian, you can build using the following:

go build -tags "php7 debian"

You do not need to pass in --ldflags '-extldflags "-static"' etc. By default, Go produces static binaries, but can only statically link against C libraries provided as .a files (which libphp7.0-embed is not).

You can, however, build PHP as a static binary yourself and try to build with:

go build -tags "static"

There are some issues with receiver bindings when statically linking, a bugfix is underway.

Well thank you.

However, please review this information at these links:

Statically compiled Go programs, always, even with cgo, using musl https://dominik.honnef.co/posts/2015/06/go-musl/

Compile statically linked with musl as an alternative to the non cgo version https://github.com/hlandau/acme/issues/113
